Abstract： Many individuals now participate in online fund investment, but novice investors often struggle with the complex information they encounter due to the lack of professional guidance in traditional offline financing. Previous research on decision-making has primarily focused on outcomes and utilized statistical methods to construct decision models, which fail to provide direct evidence of information processing. To assist novices in developing the necessary skills for making investment decisions, this study employs process tracking technology in the field of fund investment for the first time. The aim is to explore the differences in information processing between experienced investors and novices, thereby identifying the advantages experienced investors possess in information processing. Additionally, this research investigates the relationship between the decision-making process and outcomes, proposing interventions based on information processing to aid novices in making accurate investment decisions.
To achieve the research objectives, two studies were conducted. Study 1 involved a comprehensive exploration that traced the fund investment decision-making process using Mouselab. It compared various information processing indicators between experienced investors and novices, including decision-making time, depth of search, variability of search, compensatory index, and SM (strategy measure) value of the search pattern. The study also examined the impact of the search pattern on decision quality for experienced investors and novices through grouping logistic regression. Study 2 involved an intervention experiment utilizing a single-factor (structured intervention group vs. control group) between-subject design. Participants in the structured intervention group were provided a piece of form paper to guide them to structure information of funds, while participants in the control group were provided blank paper. Then all participants completed a simulated fund investment task and their decision quality was recorded.
Study 1 revealed that: (1) Experienced investors, compared to novices, preferred to utilize attribute-based search pattern during fund investment decision-making, and displayed a more non-compensatory approach to information processing. (2) Only the decision quality of novices in fund investment was affected by the information search pattern, indicating that their decision quality improved when they searched for information based on attributes. In contrast, the decision quality of experienced investors was unaffected by the information search pattern but positively influenced by working memory. Study 2 demonstrated that participants who used form paper for intervention had higher decision-making quality than those who used blank paper, indicating the effectiveness of the structured intervention.
This study makes theoretical and practical contributions to the literature. First, it explores the characteristics of the information processing process during fund investment decision-making and its relationship with decision outcomes, filling the research gap regarding the "process" of information processing and deepening the understanding of the essence of decision-making ability in fund investment. Second, it extends the "expert-novice" paradigm to the field of fund investment, summarizing the differences in the search pattern and compensatory behavior between experts and novices, further supporting the heuristic decision model. Third, it proposes effective interventions to assist novice investors in improving their online fund investment and inspires the interface design of fund applications.

Abstract： Debt is a legally or morally binding obligation on the part of an individual to repay another person or institution, either immediately or at some point in the future. As the prevalence of indebtedness among Chinese residents continues to escalate, there is growing concern over the psychological and behavioral repercussions associated with debt. Debt-induced stress can result in adverse effects on mental health, shortsighted decision-making, consumption patterns, and even unethical bebavior. Furthermore, these impacts may extend beyond the indebted individual, affecting their romantic partner and offspring. The negative effects of indebtedness can be elucidated through the threat-compensation mechanism and the cognitive resource depletion mechanism. Future research is suggested to identify additional psychological and behavioral consequences stemming from indebtedness, delineate the boundaries of these effects, explore the various dimensions of debt, develop new methodologies and paradigms for studying debt, and ultimately construct an integrated theoretical framework that describes the nature of indebtedness and provides insights into its consequences.

Abstract： Trust behavior is mainly influenced by biological and environmental factors. Through quantitative or molecular genetic studies, researchers found that genes associated with trust include oxytocin receptor genes, serotonin transporter genes, and AVPR1A gene. From a biological perspective, genes affect the production and release of hormones, while the activities of hormones and specific brain regions affect trust. From gene-environment interaction theory, genes may play a moderating role between the environment and trust behaviors. An important direction for future research is to investigate the mechanism of the occurrence and development of trust from a more integrated and systematic perspective, and to further confirm the genetic role in the genetic mechanism of trust.

Abstract： Green consumption is an ethical issue, including two types of motivation: Identity construction and environmental concern. Green consumption based on identity construction would lead to the instability of green consumption, even lies and theft, and its psychological mechanism was moral self-regulation. The green consumption performance based on environmental concern was the opposite, and mechanism of moral identity played a role. So, was it identity construction or environmental concern? It might be influenced by many factors. On this basis, we built a green consumption model based on individual life style, which clarified the problem from the perspective of individual differences. Finally, Future research needs to focus on green consumption from theory and practice.

Abstract： How to reduce social class disparities in health and education and improve social equality has drawn widely concerns across the world. Among current approaches in social class psychology, the sociocultural perspective emphasizes on how social class contexts shape the self and corresponding patterns of thinking, feeling, and acting. Starting from the class-specific self, sociocultural perspective further provides systematic explanations on how social class culture is produced and maintained (i.e., social class cycles), as well as difference education as a means to improve the adaptations of the lower-class. These theoretical perspectives incorporate and extend previous key tenets of the individual and structural models of behavior. In addition, the sociocultural perspective provides new tools for developing social-psychological interventions which aim at reducing social class disparities in health and education. Future research from the sociocultural perspective could focus on sinicization of the theory and corresponding interventions, integration with other approaches in social class psychology and social justice perspective, and examining the effects of social mobility and cultural change on social class psychology.

Abstract： Social media has now become a part of the social life, in which selfie is a kind of common information of personal appearance oriented by appearance on social media. It is found that the selfie related behaviors are closely associated with users’ body image. Such behaviors on social media include selfie investment, selfie manipulation, selfie posting, selfie viewing, and selfie feedback investment. Since individuals are both publishers and receivers of information on social media, selfie investment, selfie manipulation and selfie posting can be regarded as publishers’ initiative selfie behavior, while selfie viewing and selfie feedback investment fall into the category of receivers’ reactive selfie behavior. This study summarizes how selfie related behaviors would affect body image from two perspectives: initiative and reactive behaviors. It finds out that the reactive behaviors could generally do harm to body image, while the relationship between initiative behaviors and body image is relatively complex. To be specific, preparations before posting selfies (including selfie investment and selfie editing) would deliver negative influence on body image; meanwhile, as shown in existing researches, the effect of posting selfies on body image is not constant. Therefore, further studies are required to clarify the relationship between posting selfies and body image and find out moderating factors. The objectification theory and social comparison theory provide some theoretic perspectives to explain how selfie related behaviors affect body image. In this process, body surveillance, standard internalization and appearance comparison are involved. Although the continuity of different selfie related behaviors is relatively obscure, behaviors in different categories would influence body image in certain paths, which would change with individuals’ identities as an information publisher or receiver. When an individual act as a publisher, he or she would constantly monitor and adjust his or her body from the perspective of spectators, thus strengthening body surveillance. On the other hand, when an individual act as a receiver, he or she would learn standards of beauty from the media and peers and then internalize them gradually. Meanwhile, social comparison runs through the whole process: individuals would compare themselves with the selfie images posted by others when they browse social media, present themselves online by posting selfies, or view the feedback on their posted selfies. Since individuals are usually intended to show their best aspects to the audience online, the selfies posted are generally edited and enhanced. As a result, upward social comparison would be naturally elicited afterward. What is more, the relationships between selfie related behaviors and body image as well as the process would be influenced by intrapersonal, interpersonal and environmental factors, such as gender, age, media literacy, etc. Research on the relationships between selfie behaviors and body image can be expanded and deepened in the future from the following aspects; firstly, to widen the scope of research groups to explore the similarities and differences in the problems faced by different groups; secondly, to optimize research designs, so as to explore the relationship between selfie related behaviors and how they develop with body image; thirdly, to identify the subtle differences between selfie behaviors, while exploring different effects of various selfie related behaviors on body image; fourthly, to focus on the moderating variables which may affect the relationships between initiative and reactive selfies and body image; and fifthly, to take environmental variables into account, so as to explore the similarities and differences of the relationships between selfie behaviors and body image in different social media environments. Last but not the least, it is necessary to summarize the relevant phenomena to study the self-construction process in cyberspace, and discuss it from a theoretical perspective in order to gain more insight.

Abstract： Previous studies showed that the attractiveness rating of a face was influenced by context face, which may lead the evaluation to be closer to or far away from the attractiveness of the context, known as assimilation effect or contrast effect. It suggests the influence of context face on target attractiveness evaluation varies and needs to further clarify how it happens. However, there are two problems remain to be solved according to the manner on how the assimilation effect is calculated in previous studies. Firstly, the calculation method of assimilation effect is based on a relative standard by comparing attractiveness ratings of target faces between different contexts (i.e., T1 vs T2), which ignores the initial attractiveness of target face (T0) presented alone. This might lead to an illusive assimilation effect, where both T1 and T2 are far away from T0 and is actually a contrast effect. Secondly, there is a change of assimilation effect associated with the change of target-context difference if an illusive assimilation effect is true. But the change of target-context difference is ignored in previous studies, and how it impact on the attractiveness rating of target face remains unlcear. In this study, the assimilation effect was calculated based on an absolute standard by comparing attractiveness ratings of target faces with their initial attractiveness rated without context. In the experiment, the medium attractive faces was chosen as target face and high-attractive faces as context faces, and the attractiveness difference between the target and the context was changed in a consecutive way. A within-participant design was adopted with the attractiveness difference between the target and the context and exposure time as independent variables. The results found that under highly attractive context faces, individuals' attractiveness ratings of medium target were increased to be closer to the context, resulted in an assimilation effect. In particular, we found the assimilation effect was changed with the attractiveness difference between the target and the context, called the continuum effect in assimilation process. More interestingly, an illusive contrast effect would be concluded if comparing attractiveness ratings between different context without considering th initial attractiveness rating (i.e., a relative standard). That is, the assimilation effect might be mistaken as a contrast effect in previous studies. In addition, the exposure time affected the evaluation of facial attractiveness, and individuals were more inclined to overestimate facial attractiveness in short time.

Abstract： Recently, group emotional contagion has attracted much interest among the scholars of emotional contagion, focusing on the interactive process of emotional contagion among group members. It contains not only direct emotional contagion between two individual, but also the process of group identity, common behavior, collective rules. In addition to inter-individual emotional contagion, group emotional contagion involves two unique emotional outcomes—"emotion cycles" and "collective effervescence". To clarify the occurrence and enhancement process of group emotional contagion, this review associates the three elements of collective ritual (i.e., synchronized actions, shared attention, and shared meaning) and group emotional contagion. Then, the potential mechanisms of collective ritual on group emotional contagion is summarized. First, redundant, repetitive and synchronized actions, as well as shared attention and meaning in collective rituals can trigger the processes related to self-representation. On the one hand, the "self-referential effect" pushes individuals to project personal characteristics into the group, leading to "self-anchoring". On the other hand, collective rituals are characterized by ambiguous causality, but with symbolized social norms embodied. During the process of collective rituals, individuals tend to rely on symbolized social norms to represent themselves, and thus the self-stereotype occurs. As a result, the group identities based on self-anchoring and self-stereotyping is facilitated. Second, strong sense of belonging to the group promotes integrated identity, thereby blurring the boundaries between the individual self and the social self. Highly integrated individuals will experience a transformation of self-representation, from the individual self to the relational self or the collective self (emphasizing group identity), so that an individual will be more closely connected with the group. The group identity generated by collective rituals leads individuals to regard emotion senders as a part of the group and more likely to interpret emotional signals as positive, leading to a larger possibility of emotional mimicry in this context. Emotional imitation under collective ritual produces an emotional experience based on identity, which ultimately enables group emotion to spread on a larger scale. In conclusion, collective rituals enhance group identity through self-stereotyping and self-anchoring. Integrated identity basing on group identity makes individuals pay more attention to group identity, which further leads individuals to transform the individual self into social self and more prone to accepting the group's opinions and emotions. Future studies should further investigate the influencing factors of group emotional contagion and enrich its measurement methods.

Abstract： Preference reversal of joint evaluation is well known in the field of decision-making. The Generalized Evaluability Theory (GET), as a theory for preference reversal with the strongest explanatory power, emphasizes the role of the mode of evaluation (i.e., the presence or absence of contextual information) in the decision-making process. The theoretical models for the contextual effect of social comparison and social evaluation, e.g., the Inclusion/Exclusion Model (IEM), also emphasizes the role of contextual information (especially the similarity between context and target) in the evaluation process. Analogous to preference reversal, the contextual effect can also be explained as a kind of "decision preference" (upward assimilation and downward contrast) and its "reversal" (upward contrast and downward assimilation). Taken as analogous concepts, preference reversal and contextual effect are first introduced and compared, and then contextual effect is explained and extended from the new perspective of joint evaluation. Future research should pay attention to the following aspects to deepen the understanding of the contextual effect and promote the theoretical integration and practical implications of these two fields.牋First, how to measure contextual effects. Previous studies usually measured the contextual effects as the relative difference of the target evaluations among different contexts, which might lead to a contrary conclusion. Similar to the fact that preference reversal is concluded from the difference between joint and separate evaluations, future research on contextual effect should also take the baseline condition (i. e., the target is evaluated separately) into account. This is to avoid the inapposite measure of contextual effects of social comparison and social evaluation. 牋Second, what factors influence contextual effects. Inspired from the contextual factors of preference reversal effects of joint evaluations, future research may pay more attention to the target-context similarity for various evaluation dimensions of social comparison and social evaluation. 牋Third, the contextual effect may be extended to cross-dimensional domains. It is common for cross-dimensional trade-offs in decision-making during joint evaluations. Thus, the cross-dimensional contextual effects should not be rare in social comparison and social evaluation. Specifically, the cross-dimensional domains may be manifested as followings: 1) context and target are cross-dimensional, 2) target evaluation on one dimension (e.g., trustworthiness) is impacted by the ingroup/outgroup relationships between the evaluator and target resulted from another feature (e.g., race), and 3) contextual effects are modulated by the relevance between the contextual dimension and the target dimension, and so on. 牋Finally, the contextual effect can be linked into practical applications. Decision-making is common in practical context, and the new perspective of joint evaluation can provide insights for the decision-making dilemma related to contextual effects, in particular when the target and the context are extremely similar leading to a hard prediction of the occurrence of the assimilation effect. Besides, based on the perspective of joint evaluation, multidimensional criteria in real situations such as interviews should be evaluated separately to minimize the adverse impact of contextual assimilation and contrast, when it is more difficult to evaluate the key criterion than the less important criterion. Therefore, the perspective of joint evaluation can inspire the application of contextual effect in a wider range of evaluation and decision-making situations in the future.

Abstract： Warmth and competence are the two fundamental dimensions (i.e. Big Two) in social cognition. According to the Dual Perspective Model (DPM), warmth is the primacy of the Big Two and the Big Two are differentially linked to the actor (self) vs. observer (other) perspectives. In the observer perspective, warmth is more relevant and more important; whereas in the actor perspective, competence is more relevant and more important. Another domain of literature on social class psychology suggested that lower-class individuals were more sensitive to external environment and valued interdependent self; whereas upper-class individuals were more self-focused and valued independent self. The current study combined these two domains of literature and examined possible moderating role of social class on the link between the Big Two and the actor vs. observer perspectives. Specifically, we hypothesized that both lower-class individuals and upper-class individuals would value warmth more than competence in evaluating others, and this primacy of warmth would be more evident for lower-class individuals (H1). In contrast, lower-class individuals would also value warmth more than competence whereas upper-class individuals would value competence more than warmth when evaluating themselves (H2). Two studies were carried out to test these hypotheses. In Study 1, 122 undergraduate participants were presented with a list of 8 sentences each describing a behavior of a stranger. The behavioral acts were deliberately chosen to be amenable to both warmth and competence traits. Participants were asked to use a single word to describe the character of the subject in each sentence. Information on participants’ objective socioeconomic status (SES, family income and highest parental education level) was also collected. In Study 2, 137 community participants were asked to rate the importance of 12 traits (6 on warmth dimension, 6 on competence dimension) in evaluating themselves. The MacArthur scale was used to assess participants’ subjective social class rank. In Study 1, more warm words (as compared to words on the competence dimension) were chosen to describe the character of the subjects in the sentences. This pattern was consistent among both lower- and upper-class individuals. In addition, lower-class individuals used significantly more warm words than upper-class participants. In Study 2, lower-class individuals scored significantly higher on warmth than competence. Contrary, upper-class individuals scored significantly higher on competence than warmth. Taken together, findings from these two studies provided evidences to support our hypotheses. The current study contributes to the social cognition literature by integrating the DPM and social class psychology. Social class does influence the primacy of warmth vs. competence as demonstrated previously in DPM. The primacy of warmth in evaluating others is more typical for lower-class individuals and the primacy of competence in evaluating themselves is more typical for upper-class individuals. Moreover, DPM further develops the ideas of social class psychology. Lower-class individuals showing contextual social cognitive tendencies and upper-class individuals showing solipsistic social cognitive tendencies are reflected very well in the primacy of warmth vs. competence in evaluating others vs. themselves. Uncovering the nuances in social cognition between lower and upper classes also provides important practical implications to promote healthy inter-class communications.

Abstract： In sentence production, syntactic priming effect refers to a phenomenon that speakers or writers tend to reuse syntactic structures that they have recently processed, and the repeated syntactic structures elicit shorter sentence production latencies than the novel ones. Different theories have been proposed to account for the syntactic priming effect. Among them, both the Residual Activation Theory and the Implicit Learning Theory aim to address speakers’ syntactic choices ratio, but with different theoretical bases on memory and learning, respectively. In addition, the Two-stage Competition Model attempts to explain the syntactic priming in syntactic choices ratio as well as production latencies. Experimental works have demonstrated that syntactic priming stably exists even after excluding the semantic and lexical relevance between the prime sentence and the target sentence, which suggests that syntactic priming actually reflects syntactic processing in sentence production. In the present study, we explored the cognitive mechanism of syntactic processing in Mandarin spoken sentence production using a syntactic priming paradigm. In this paradigm, participants were firstly instructed to read the prime sentence aloud and then judge whether the sentence’s description matched the prime picture. Then, participants were instructed to describe the target picture using the verb at the bottom. The dependent variables included not only the syntactic choices ratio but also the sentence production latencies. In experiment 1, we manipulated syntax structure of the prime sentence (double object dative vs. prepositional object dative) and verb overlap between the prime sentence and the target sentence (no verb overlap vs. verb overlap). In experiment 2, we added a within-subjects factor of lag by manipulating whether the target picture was presented immediately after the prime sentence, or after two or six intervening descriptions (Lag 0 vs. Lag 2 vs. Lag 6). For the syntactic choices ratio, results indicated that participants produced significantly more double-object sentences following double-object primes than following prepositional-object primes, and the syntactic priming was much stronger in the verb overlapping condition than in the verb non-overlapping condition. Furthermore, we found that the syntactic priming effect persisted when the prime sentence and the target sentence did not share the verb, whereas the lexical boost effect (i.e. a stronger syntactic priming effect caused by the verb overlap between the prime sentence and the target sentence) disappeared after six intervening descriptions. For the sentence production latencies, results indicated that the repetition of syntactic structures significantly speeded up target sentence production. Besides, we found that verb overlap slowed down the sentence production as the lag between primes and targets increased (also known as the lexical suppression effect) only when the syntactic structure was repeated. Unifying the different findings in the syntactic choices ratio and the production latencies, we suggest that, apart from the stage where a sentence is planned specifically, sentence production comprises a syntactic construction stage in which speakers map the thematic roles to one structural alternative. These findings are consistent with the Two-stage Competition Model. In methodology, we also suggest that syntactic choices ratio is sensitive to sentence generation process.

Abstract： Language is a complex lifelong faculty supported by the general cognitive system as well as the dynamic interactions between comprehension and production processes within the language system. Studies reported that while normal aging impairs important aspects of language production, most core processes of comprehension are robust. However, accumulating evidence suggests a decline in comprehension when comparing older adults with young ones. Thus it is plausible to assume that there might be a general degradation in older adults’ language capacity. The information-universal theories assume that the aging of language is contributed by the declines in general cognitive abilities including processing speed, working memory and inhibitory function, while the information-specific theories highlight the unique changes of linguistic representations and their connections in the brain, which may result in decreased interplay between comprehension and production. The current study investigated the relationships among language comprehension capacity, production capacity, and general cognitive abilities, and explored the factors that influence the aging of language processing. We employed two groups of participants (103 young adults and 114 older adults), and measured their general cognitive abilities and language capacities with different tasks. General cognitive abilities were assessed in three dimensions: processing speed by color judgment and numerical judgment tasks, working memory by digit span forward and backward tasks, and inhibitory function by STROOP color-word judgment task. Language comprehension and production capacities were measured at word, sentence and discourse processing levels, respectively. We first compared the performance between the two age groups, and then conducted hierarchical regression analyses to examine the contributions of information-universal and information-specific factors to language performance. Results showed lower scores in older adults than their young counterparts on all measures. The first hierarchical regression analyses revealed that there were differences between the older and the young groups, which presented not only in the contributions of general cognitive abilities to language capacities but also in the contributions of comprehension and production capacities to each other. For word processing, young adults’ performance was predicted by both general cognitive abilities and the other language capacities, while the former did not predict older adults’ performance; for sentence processing, young adults’ performance was predicted by general cognitive abilities (only in comprehension) and the other language capacities, while neither of them explained older adults’ performance; for discourse processing, young adults’ comprehension scores were predicted by their production capacity, while older adults’ scores of comprehension and production were predicted by their general cognitive abilities and comprehension capacity respectively. Results of the second hierarchical regression analyses indicated that both general cognitive abilities and the other language capacities contributed to the group differences in language performance, and the contributions of the former were larger than those of the latter. In sum, older adults show an overall age-related decline in general cognitive abilities, language comprehension and production capacities. We suggest that the aging of language processing is subject to both the information- universal factor as well as the information-specific factor, with the former reflected as the general degradation in cognitive abilities and the latter related to specific changes in the architecture of language system.

Abstract： Emotion regulation plays an important role in maintaining mental balance. Automatic emotion regulation is an important aspect of emotion regulation. Previous studies has found that automatic emotion regulation can influence emotional attention bias, and the activation of the left orbitofrontal cortex (OFC) was related to attention allocation to negative emotional stimuli. Although previous studies have provided evidence to the involvement of left OFC in the mechanism of automatic emotion regulation's influence on attention, little studies provided evidences for this hypothesis by manipulating the activation of left OFC. In order to examine the role of left OFC in attention allocation under automatic emotion regulation, the present study manipulates the cortical excitability by using transcranial direct current stimulation (tDCS). We hypothesized that under the cathodal stimulation codition, the effect of subliminal emotional control words on attention avoidance of fear stimulation was diminished. Thirty-nine healthy right-handed college students participated in this study. Each participant was settled into cathodal and sham tDCS sessions in random order. After entering the laboratory, the participants completed a state-trait anxiety questionnaire. Then they completed the pre-task, in which emotional control goal was subliminally presented in the beginning of each trial. And fear related dot probe task was adopted in the pre-task. After the task was completed, the participants received tDCS stimulation. A relatively weak current (±1.5 mA) was constantly delivered over the left OFC for 20 min. For the sham tDCS, the stimulation only lasted for 15 sec. After stimulation participants immediately completed the post-task, in which the same task with the pre-task was used. The present study analyzed accuracy and reaction time by a 2 (pre-tesk and post-task) × 2 (tDCS: cathodal, sham)×2 (left-right location consistency of snake picture and target) repeated measures ANOVA. The results showed that the main effect of location consistency was significant (F(1, 37) = 5.11, p < 0.05, ηp2 = 0.12), and the reaction time under the consistent condition was significantly greater than that under the inconsistent condition. The interaction between the location consistency and stimulus conditions was significant, F(1, 37) = 9.78, p < 0.01, ηp 2 = 0.21. The simple effect analysis revealed that under the condition of sham stimulation, the reaction time under the consistent condition was greater than that under the inconsistent condition (ps < 0.05). For the cathodal stimulation, there was no significant difference between the reaction time under the consistent condition and the inconsistent condition (p > 0.05). The interaction between the consistency of pre- and post-task, stimulation condition and location consistency was significant, F(1, 37) = 11.41, p < 0.01, ηp2 = 0.24. Simple effect analysis showed that under the condition of sham stimulus, the response time under the consistent condition was greater than that under the inconsistent condition (ps < 0.05). Under the cathodal stimulation condition, the response time under the consistent condition was greater than that under the inconsistent condition (p < 0.05), while the response time under the consistent condition was significantly less than that under the inconsistent condition (p < 0.05). The present study examined the role of left OFC in attention allocation under automatic emotion regulation using subliminal goal priming and dot-probe task. Our findings revealed that after cathodal stimulation, attention avoidance of fear stimuli induced by subliminal control goal priming would be diminished, suggesting that the activation of left OFC influenced emotional attention allocation in automatic emotion regulation.

Abstract： Languages may differ in the proximate units of phonological encoding in spoken word production. It has been demonstrated that syllables are proximate units of phonological encoding in Chinese speech production. Previous studies report that the θ band oscillations has been associated with syllables processing in language comprehension, however, it remains unknown what are the neural oscillations for syllables retrieval in speech production. The present study aims to investigate the neural oscillations of syllables retrieval at the stage of phonological encoding in Chinese spoken word production. We employed a masked priming paradigm and electrophysiological signals were recorded concurrently. In the task, participants were instructed to name pictures with disyllabic words which were preceded by briefly presented and masked prime words. Prime words were syllabically or phonemically related to the first syllable of targets or were unrelated, and the experimental design includes prime type (syllable vs. phoneme), relatedness (related vs. unrelated), and repetition (first vs. second). Behavioral data analysis showed a significant triple interaction among prime type, relatedness and repetition. In the first repetition, naming latencies were faster in syllabically related than unrelated condition, whereas latencies were longer in the phonemically related than unrelated condition. Time-frequency analysis also showed a significant interaction between prime type and relatedness in the time window of 300-600 ms after pictures onset. Specifically, theta band power was lower for syllabically related than unrelated while no significant differences between phonemically related and unrelated. Cluster based permutation test showed that, in the first repetition, syllabically related condition elicited lower θ band power than unrelated in the time window of 270-460 ms, while phoneme relatedness produced marginally higher θ band power than phoneme unrelatedness in the 340-390 ms time window. These effects were absent in the second repetition. In sum, we found that syllable priming effect was reflected by the decrease of θ oscillation in spoken word production in Chinese. Time-frequency analysis also revealed an early syllable priming effect, and a late phonemic inhibition effect in Chinese spoken word production, which provides evidence for the proximate units principle.

Abstract： A debatable issue between serial discrete models and interactive models is whether non-target lemmas activate their phonological words in spoken word production. Serial discrete models assume that only target lemma activates its corresponding phonological node to articulation, whereas interactive models assume that the semantic and phonological nodes linked to multiple candidates are co-activated during the retrieval of target word. Multiple phonological activation has been supported by evidences from alphabetic languages, but it remains unknown whether this finding can be generalized to non-alphabetic languages. Therefore, the current study aimed to investigate whether the not-to-be named pictures activate their phonological nodes in Chinese spoken word production.Using electrophysiological measures, the present study employed a word translation task in native Chinese speakers with a high level of English proficiency. Thirty-two participants (13 males, average 22.94 years) were presented with an English probe word and a context picture (semantically related or unrelated, phonologically related or unrelated to target word) simultaneously. Eighty-six English probe words from CELEX database and forty-three black and white line pictures from a standardized picture database in Chinese were chosen as stimuli. Participants were asked to translate English probe words into Chinese as accurately and quickly as possible while ignoring context pictures presented simultaneously.Behavioral results showed a typical semantic facilitation effect, with faster translation latencies in the semantically related condition than in the semantically unrelated condition. More importantly, phonological overlap, which generally elicits priming in Indo-European languages, resulted in a null finding for Chinese production. Electrophysiological results revealed that semantic relatedness induced significant effects of ERPs after stimuli presentation: a widely distributed positivity in the 400- to 600-ms interval, while marginally significant effects were observed for phonological relatedness in the time interval of 600~700 ms in the right middle region. Furthermore, a negative correlation between the difference of translation latencies (semantically related minus semantically unrelated) and the difference of mean amplitudes (semantically related minus semantically unrelated) approached significance in the 400~600 ms time window in the middle posterior region, suggesting that more positive mean amplitudes were associated with shorter translation latencies.Although speakers present a weak but reliable neural activation, we suggest that phonological overlap between context pictures and target words had no impact on the translation processing in behavioral. That is, the non-target lemma did not activate their phonological node, and multiple phonological activation was absent in Chinese spoken production. Meanwhile, the semantic information of context pictures was indeed activated, and according to the temporal course of word translation, the time window of 400~600 ms was estimated for conceptual preparation when Chinese-English bilinguals completed a word translation task, although this activation was not transmitted from semantic level to phonological level. Overall, the present findings support a serial discrete model rather than an interactive model in Chinese spoken word production.

Abstract： Depression is an important and widely studied measure of individual psychological and social adaptation. Previous studies have explored the mechanism of depression from various perspectives and found that addiction is a significant risk factor for the development of depression. In recent years, with the rapid development of mobile Internet technology and smart phones, researchers have found that mobile phone addiction, as another important aspect of behavioral addiction, also has a potential impact on depression. Further studies have found that mobile-addicted individuals spend too much time and energy in the virtual world, thus leading to social anxiety. In addition, when social anxiety is so high that it affects the daily life of individuals, individuals are prone to suffer depressive symptoms. According to the cognitive behavioral model of social anxiety and emotional consistent effect, attentional bias to negative information is a key factor in maintaining the anxiety state among individuals with social anxiety. When an individual experiences social anxiety, they will pay more attention to negative information. Depression cognitive theory also posits that attentional bias to negative emotional information is closely related with the occurrence, development and maintenance of depression.Therefore, social anxiety and attentional bias to negative emotional information may be important factors in the effects of mobile phone addiction on depression. This study integrated emotional and cognitive factors and explored the effects of social anxiety and attentional bias to negative emotional information on the relationship between mobile phone addiction on depression through two studies. For study 1, a sample of 545 college students completed the Mobile Phone Addiction Index, Beck Depression Inventory and Social Interaction Anxiety Scale. For study 2, 51 college students were selected to complete questionnaires and a 2 (Emotional types of paired facial expressions: negative, neutral) × 2 (Detection point position: same as negative emotional face expression, different from negative emotional face expression) within-subjects task to investigate the serial mediating effects of social anxiety and attentional bias to negative emotional information on the relationship between mobile phone addiction and depression.All the data were analyzed by SPSS 20.0 and Mplus 8.3. Some valuable results were obtained as follows. (1) There were significant positive correlations among mobile phone addiction, social anxiety and depression. Social anxiety fully mediated the effect of mobile phone addiction on depression. (2) Social anxiety and attentional bias to negative emotional information serially mediated the relationship between mobile phone addiction and depression. However, attentional bias to negative emotional information did not significantly mediate the effect of mobile phone addiction on depression. Specifically, mobile phone addiction affects depression through two pathways: one is the separate mediating role of social anxiety; the other is the serial mediation pathway of social anxiety → attentional bias to negative emotional information.This study expands previous research on mobile phone addiction and individual psychological adaptation, enriches the field of addiction and depression research, and has significance regarding the reduction or control of the negative effects of addiction on depression. Additionally, this study also provides evidence for causal inference that social anxiety and attentional bias can alter depression levels, suggesting that attentional bias training is likely to be a promising alternative therapy for depression and providing new ideas for the intervention and treatment of clinical mental disorders.

Abstract： Previous research demonstrated that ensemble perception of groups can be formed rapidly by extraction of the average of high-level complex features. However, it is unclear whether the average percept is the outcome of extraction from the characteristic value of the average stimulus (for example, average face) created from group members, or from calculation of the average value of group members’ characteristic values. The above two values were confused with each other in prior research, since most average value of group members are similar as the characteristic value of the average stimulus. However, the attractiveness rating of the average face created from a group of faces is usually systematically higher than the mean value of attractiveness ratings of this group of faces. Therefore, it is easier to explore how the ensemble coding of crowd face attractiveness (i.e. group attractiveness) is formed by comparing the attractiveness of the average face with the mean value of attractiveness rating of a group of faces. This could provide a useful approach to explore how the average percept is formed. The present study used the average discrimination paradigm (Experiment 1 & 2) and the scoring paradigm (Experiment 3 & 4) to clarify the mechanism of the formation of average percept by comparing the group attractiveness with the attractiveness of average face. To tackle this issue, whether the average face was presented in the group of faces or not was manipulated (conditions: Avg vs. NoAvg). Group size were also manipulated to explore whether group size modulated the formation of average percept. In the average discrimination paradigm, a group of faces served as group stimuli to be compare with the probe face for attractiveness. Participants were asked to judge which is more attractive between the group stimuli and the probe face. In the scoring paradigm, participants were asked to rate the attractiveness of group stimuli, the average face created from the group, and each face of the group in isolated manner. Each group consisted of twelve (in Experiments 1 and 3) or four faces (in Experiments 2 and 4). There were two kinds of groups: one is that all group members are original faces, without the average face. The other is that an average face morphed from other original faces was included in the group. In Experiment 1, the proportions for judging probe average face more attractive than group attractiveness in the Avg condition was similar with the NoAvg condition. In Experiment 2, when the set size was four, the proportions for judging probe average face more attractive than group attractiveness were significantly higher in the NoAvg condition. Moreover, in Experiment 3, the ratings for group attractiveness were not significantly different between Avg and NoAvg conditions. This may indicate that the group attractiveness is based on the average face which was created from group members rather than the mean value calculated from group members’ attractiveness. In addition, the diffusion model analysis showed that the coding time was longer for NoAvg condition, which indicated that the formation of average face needed cognitive resource. In Experiment 4, when the set size was four, the attractiveness rating of the average face was significantly higher than group ratings for the two kinds of groups. The different results in different group size may be interpreted as the outcome of weakened average percept caused by the salient individual face representations in small group. This was evident from several analyses: 1) group attractiveness and the attractiveness of morphed average face decreased with smaller set size (Experiment 4); 2) When the probe face was morphed average face, the proportion for judging probe face as more attractive than group attractiveness was greater, comparing with the condition when the probe was a new face whose attractiveness was similar with the morphed average face (Experiment 2); 3) The performance for the hypothesized condition with average percept included in the set is in between the conditions with/without real average face included (Experiment 2-4). In addition, comparing with Experiment 1, the information accumulation speed in Experiment 2 is slower, the processing time of group attractiveness is longer, reflecting the disturbance of the individual face representation. In summary, the findings supported the hypothesis that group attractiveness is based on the morphed average face. Thus, the ensemble percept relies on the extraction from the average stimulus created from the group.

Abstract： Nowadays, emergent online events have occurred frequently, because of the social transition and the development of social media. In the past, most of the research on emergent online events were theoretical analysis, and less attention was paid to the psychological mechanisms. The current research proposes that negativity bias, a common psychological phenomenon in human decision-making, is an important mechanism behind the network emergency and its propagation. In order to explore the occurrence and performance of negativity bias in emergent online events, three theoretical hypotheses were tested by three studies under the guidance of a theoretical model. Study 1 aimed to explore the information content bias in the source texts of emergent online events. 40 source texts of emergent online events in the period from 2016 to 2019 were collected through Baidu, Sina, Tencent and other major media platforms. The Chinese psychoanalysis System TextMind 3.0 was used to analyze the texts. In Study 2, a recognition memory experiment was conducted to explore the information processing bias of the source texts of emergent online events. 48 participants completed the single-factor (word nature: positive, neutral and negative) within-subjects experiment. The reading materials used in the experiment are from the corpus set up in Study 1. Positive, neutral and negative words were selected from the text by online word segmentation tool in advance, and the subjects were asked to recall whether the words appeared in the article in the subsequent memory experiment. Study 3 aimed to explore the transmission bias in the dynamic propagation of emergent online events. One hundred and twenty participants (Thirty transmission chains) took part in the transmission experiment. Word nature was a within-subjects variable, which can be divided into three levels: positive, neutral and negative. Intergenerational transmission was a between-subjects variable including four generations. Study 1 indicated that although all negative words did not dominate in the source texts of emergent online events, there are more negative words in the source texts of emergent online events than that of hot network events. Study 2 showed that the recognition accuracy of negative words was higher than that of positive words and neutral words. The analysis based on signal detection theory showed that the participants had higher discrimination and stricter decision-making criteria for negative words than positive and neutral words. Therefore, the negativity bias of the participants was mainly reflected in the fact that they were more likely to recognize negative words that are not in the text. Study 3 indicated that the survival rate of negative events was higher than that of positive events and neutral events, and that of positive events was higher than that of neutral events. The probability of negative interpretation of neutral events was higher than that of positive interpretation. These results supported the negative advantages in the process of emergency transmission. The current study investigated the occurrence and manifestation of negativity bias, an important psychological function formed in the process of human evolution, during the brewing, breaking out, and spreading process of network emergency. That is, the negativity bias did not only originate from the source texts of emergent online events but also from the process of individual information processing and interpersonal information transmission. This is manifested in the higher recognition accuracy, higher discrimination, sightly tight decision-making criteria for negative words, the higher survival rate of negative events, as well as negative resolution of ambiguous events. This research is conducive to understanding the law of information dissemination of emergent online events, scientific response to the crisis of public opinion, and innovative network governance.

Abstract： A controversial in word production is that how speakers retrieve words from the mental lexicon. The picture-word interference (hereafter PWI) paradigm has been broadly used to investigate this issue. In this task, speakers are instructed to name pictures while ignoring written distractor words superimposed onto the pictures. A typical finding is the semantic interference effect, which is that categorically related distractors (e.g., bus) slow down picture naming (e.g., car) relative to unrelated distractors (e.g., pen). By varying stimulus onset asynchrony (SOA) between pictures and distractors, studies have reported semantic facilitation effect when semantically related distractors were presented before pictures such as 400 ms (-400 ms), and semantic interference effect when semantically related distractors were presented closely to pictures. Lexical competition hypothesis assumes that semantic interference reflects the lexical selection competition among co-activated semantically related lexical representations during lemma retrieval, while response exclusion hypothesis assumes that semantically related distractors are more difficult to exclude from the response buffer than unrelated ones. It assumes that semantic facilitation effect arises at the conceptual processing. However, little is known about the temporal courses of both effects. The present study aims to examine the influence of SOA on semantic effect with the PWI task using electrophysiological measures. Forty-five undergraduate and graduate students participate in the experiment (22 males, average 22.85 years). Forty-two black and white line pictures were chosen from a standardized picture database as targets with disyllabic names. Each target picture was paired with a semantically related distractor word and an unrelated distractor word. Context words in the semantically related condition were then recombined with the picture names to form unrelated conditions. Target pictures and context words are basic-level concepts selected from 14 semantic categories. The experimental design included relatedness (semantically related vs. semantically unrelated), SOA (-400 vs. 0 ms) and repetition (first vs. second) as within-participants factors. Behavioral results indicated a typical semantic interference effect at SOA of 0 ms while the semantic effect was absent at SOA of -400 ms. Electrophysiological results showed that at SOA of 0 ms semantically related distractors elicited a smaller modulated waveform than unrelated ones in the time window of 344~414 ms in the first repetition and 356~418 ms in the second repetition. There was a larger waveform in the semantically related distractors than unrelated ones in the time window of 462~594 ms in the first repetition and 460~544 ms in the second repetition. At SOA of -400 ms, results showed an early semantic effect in the time window of 0~76 ms in the first repetition but disappeared in the second repetition, and a late semantic effect in the time window of 284~390 ms in the first repetition and 274~382 ms in the second repetition. In sum, the present findings indicated that there is a semantic facilitation effect arising at the conceptual processing (0~200 ms) and a semantic interference effect arising at the lexical selection stage (250~450 ms) in Chinese spoken word production. Our findings firstly provide evidence for lexical competition hypothesis rather than response exclusion hypothesis. Furthermore, with high-time resolution measures, we firstly provide electrophysiological evidence for the trade-off of semantic facilitation and interference effect in spoken word production.
