Abstract： While there has been much research concerning how adults understand the social power, recently researchers have been increasingly interested in how children conceptualize social power. Social power understanding is an important aspect of children’s social cognition, which can be reflected on the level of social dominance and social status. From early on, children can use different cues to judge social power, and based on these cues their cognition of social power are adaptive in evolutionary fitness. Meanwhile, children’s understanding of social power develops across the whole childhood. While younger children are more likely to acknowledge the way to get social power with dominance, older children prefer the way to get social power basing on prestige. Children’s cognition of social power can influence their selective trust, resource allocation, and prosocial behavior. Future research should consider the underlying mechanism of children’s social power cognition, and examine the processing mechanism of the relationship between children’s social power cognition and their social behavior. Moreover, cultural factor and early social interactive experience should be concerned to contribute to children’s cognition of social power.

Abstract： Cognitive models of social anxiety propose that socially anxious individuals tend to interpret ambiguous social events differently than healthy controls, embodying the presence of a negative interpretation bias and a lack of positive interpretation bias. This interpretation bias has been considered to play an important role in the etiology, maintenance, and recurrence of the disease. Many studies suggest that interpretation bias, as well as negative affect, can be directly shifted through repeated experiential practice, known as Cognitive Bias Modification of Interpretation (CBM-I). This has led to a growing interest in exploring the clinical potential of this “bottom-up” intervention. However, there has been some controversy about the heterogeneity of studies and the uncertainty about the cognitive mechanisms of this approach in the recent decade. The present article summarizes the frequently-used paradigms and reviews studies in terms of participants’ age and clinical status. Moreover, it focuses on discussing the potential cognitive mechanisms of CBM-I. An intervention model for the underlying mechanisms is proposed based on established cognitive models of social anxiety disorder and relevant factors (self-imagery, self-esteem, evaluation of threatening messages, fear of positive evaluation, long-term memory, anxiety sensitivity, and avoidance). Limitations of the studies reviewed are analyzed from five aspects: interpretation bias, social anxiety, transfer effect, experimental design and study heterogeneity. Directions for future research are addressed as well.

Abstract： Visual motion perception is the process human brain perceives the dynamic/motion characteristics of objects. Individuals with autism spectrum disorders exhibit deficits in visual processing, such as in optical flow, second-order motion, coherent motion, biological motion, motion speed, and obsessing in repetitive moving objects. While various hypotheses (the Dorsal/Magnocellular pathway-specific hypothesis, Complexity-specific hypothesis, Neural noise hypothesis, Flatter-prior hypothesis, Temporo-spatial processing deficit, Extreme male brain hypothesis, and Social brain hypothesis) have been proposed to explain the abnormal visual processing in autism, none of them has been proven definitively so far. Future study should focus on investigating individual differences and neural mechanism of abnormal visual motion perception, integrating and verifying the hypotheses, as well as exploiting effective evaluation tools and interventions.

Abstract： One of the long-standing state among scholars researching the psychology of Creativity is that while western theories stress the importance of big-C, little-C, the process, the person, the product, the press and other concepts of Creativity from an ever-expanding variety of disciplines. But these systems are various and complicated, making man difficult grasp the point of the problem. In order to analyze the scope of application of each theory (mainly including Kaufman’ Four-C Model, Csikszentmihalyi’s Systems Model of Creativity, Sternberg’s Propulsion Theory of Creative Contributions, Amabile’s Componential Model of Creativity, and Gl?veanu’s 5A Theory of Creativity), we summarized these systematic theories of creativity from two directions, forming a rectangular coordinate system that we called the Galaxy Developmental Model for it is analogous to the process of galaxy development. One direction is perspective of development (from Mini-C to Little-C, then Pro-C, and finally Big-C); Another is perspective of connection (from the cognitive neural basis of creativity to the process of creativity…finally the socio-cultural aspect of creativity). We are trying to provide a method allowing us to understand each theory clearly and to establish systems view of creativity, as well as paving a way for further research and application.

Abstract： Cognitive control is essential in conflict processing. Most related theories elucidated the mechanism via integrating both the enhancement of task-relevant stimuli and inhibition of task-irrelevant stimuli, which has been challenged by recent studies. We reviewed the major debates on whether enhancement or inhibition might be the mechanism and their empirical evidences, and then argued that conflict resolution mechanisms might not be constant, but depend on conflict situation and individual state. Future studies could pay more attention to reveal the influence factors of cognitive control, exploring cognitive processing strategies and doing cognitive training, which may benefit the intervention treatment of the cognitive function disorders.

Abstract： In this article, we reviewed the large body of research examining the impacts of social change on human psychology and culture. Our review revealed an increasing trend of individualism and, at the meantime, decreasing collectivism. This trend manifests on various societal and individual-level indicators, including relationship structures, first-person pronouns use, naming practices, value preferences, personality, sexual and religious attitudes, child-rearing goals and child development, cognitive styles and emotional experiences. Our review also demonstrated the complexities of cultural and psychological change, including the non-linearity of the change, endurance of traditional culture and emerging multi-cultural society. At the end, we pointed out some limitations of the existing research and highlighted some possible directions of future research.

Abstract： Schizophrenia is a severe mental disorder typically began in late adolescence or early adulthood. To date, the cause of schizophrenia remains largely unclear. The classical dopamine hypothesis of schizophrenia is now thought to be sided. Meanwhile, the involvement of impaired Parvalbumin positive interneurons (PV+ neurons) in the pathological mechanism of schizophrenia has been realized and received increasing attention. Generally, PV+ cells is a kind of inhibitory, fast-spiking interneurons, which had been demonstrated to be involved in synaptic plasticity, excitation/inhibition balance and neurogenesis. In schizophrenia, abnormal PV+ neurons has been commonly found in patients and relevant animal models., In this article, we reviewed the roles of deficits of PV+ neurons in schizophrenic pathology combined its principal phenotypes including defective NMDA receptors, abnormal gamma oscillation and oxidative stress, hoping to contribute to further investigation and development of new drugs.

Abstract： Resilience, a cross-disciplinary construct, develops along the psychological and systematic trajectories. Along with those two independent trajectories, this paper summarizes the types, definitions and measurements of resilience, draws the outline of developing paths based on the Conservation of Resource Theory, and then interventions are presented. Future research could try to explore the inducing mechanism of positive events on resilience and the relationships among cross-level resilience, and carry out local empirical research based on two trajectories above.

Abstract： In these years, researchers have begun to apply transcranial alternating current stimulation to the field of mental disorders. Especially, the gamma- and alpha-band frequencies are attracting the most attention. Previous studies have found that using γ-tACS to intervene abnormal brain activity can alleviate cognitive impairment and bring emotional benefits in various mental disorders, such as improving attention and memory functions, and reducing the depressive and anxious symptoms. The α-tACS have been used to modulate abnormal alpha oscillations and brain network connections in mental disorder, which could improve abnormal perceptual processing and enhance emotion regulation function in schizophrenia, depression and anxiety disorders. In addition, few studies have found that θ-tACS could improve cognitive functions in schizophrenia and ADHD, and 77.5 Hz, 15mA-tACS could modulate the release of neurotransmitters in MDD and chronic insomnia. Based on these clinical trials and case reports, the underlying mechanisms of the effects of tACS on mental disorders might be directly modulating abnormal brain neural activities and indirectly improving cognitive functions of patients'. First, neuroimaging studies have shown that a specific frequency tACS targeting specific brain region could modulate the nerve oscillations of corresponding frequency and brain functional connections, which directly reducing clinical symptoms of patients. Second, instead of targeting the specific damaged brain activity in mental diseases, the tACS is used to activate neural circuits associated to cognitive functions, so as to improve the attention, memory and other cognitive functions, thus alleviating adverse symptoms indirectly. At present, there are still some unsolved problems in theapplication of tACS in mental disorders. Firstly, the comparative analysis of the stimulation parameters and experiment paradigms is helpful to formulate standardized stimulation protocols and guide the clinical treatment. Secondly, one of the main hypotheses of tACS intervention mechanism in mental diseases is to target the abnormal brain activity of patients. Therefore, high definition tACS is an important method to improve the stimulation accuracy. In addition, the tACS intervention accompanied by EEG recording is also a concern to researchers. Compared with delayed recording, synchronous recording of EEG can better reflect the effect of tACS on brain neural activity, and this dynamic feedback is more conducive to personalized intervention protocol. In conclusion, the tACS is expected to be a safe and effective method for diagnosis and treatment of mental disorders. The mechanism of its effects, the improvement of stimulus parameters and paradigms, and the enhancement of technique upgrading may become the key direct of future study.

Abstract： One of the most imperative issues in developmental research on social cognition is whether young children selectively trust informants' testimonies and revise their beliefs based on those testimonies. Previous research has shown that both the nature of the information and the traits of informants affect young children's selective trust and belief revision. However, the role that contradictory information may play in young children's selective trust and belief revision has yet to be examined. The present study examined Chinese preschoolers' selective trust and belief revision in situations in which their beliefs were contradicted by information provided by a familiar informant (the mother).The present study adopted the conflicting sources paradigm. Testimonies about hybrid pictures with different perceptual cues (the 50%-50% hybrids task vs the 75%-25% hybrids task) were presented to 74 4- to 6-year-old preschoolers, to investigate young children's selective trust and belief revision. Participants heard two informants (the mother and the stranger) name the hybrid differently. In all tasks, the stranger’s naming was more consistent with the perceptual cues. Children were asked about their own naming (What animal is this?), whom they would like to ask (mother or stranger?), whom to believe and the endorsement question (What animal do you think this is?).The results showed that children's selective trust and belief revision are influenced by the degree of conflict between mother's testimonies and perceptual evidence. In the low conflicting situation (50%-50% hybrids task), children are more inclined to ask for and explicitly trust the mother's testimony than in the high conflicting situation (75%-25% hybrids task). Furthermore, in the low conflicting situation, older children are more likely to revise their beliefs than younger children; whereas in the high conflicting situation, older children are more hesitant to revise their beliefs than younger children. The findings indicate that older children are more flexible in selective trust and belief revision. They are better able to factor the available perceptual cues into their consideration of the adult's testimony.In summary, 4- to 6-year-old preschoolers' selective trust and belief revision are influenced by the degree of conflict between others' testimonies and perceptual evidence. In high conflicting situations, they typically refuse to ask for and endorse the testimonies provided by the familiar informant, or to revise their beliefs. The results of the present study demonstrate that young children are able to distinguish between different degrees of conflict. When the mother's testimony conflicted dramatically with the young children's existing beliefs, older Chinese preschoolers in our study tended to distrust the mother and refused to revise their beliefs.

Abstract： Mainstream theorists in risky decision-making have developed various expectation-maximization-based theories with the ambitious goal of capturing everyone’s choices. However, ample evidence has revealed that these theories could not capture every individual’s (“every one’s”) actual risky choice as descriptive theories. Substantial research has demonstrated that people do not follow the logical process suggested by expectation-maximization-based theories when making risky choices but rather rely on simplifying heuristics. From our perspective, the possible reason why mainstream decision theorists did not abandon the framework of expectation is that these theorists never doubted the validity of the expectation rule as a descriptive rule in describing decision-making under risk. We believe that expectation-maximization-based theories may capture risky choices when individuals make decisions for everyone. However, whether these theories could capture risky choices when individuals make decisions for themselves cannot be taken for granted. We thus used an eye-tracking technique to explore whether a theory for everyone would work well for every one. A total of 52 college students participated in the experiment. Three risky choice tasks were conducted in the present study: a D-everyone task, a D-multiple task, and a D-single task. In the D-everyone task, participants were asked to choose the more optimal option out of two options under the assumption that their selection would be the final decision for everyone who was facing the same choice—that is, everyone would be subject to the same choice but could receive different outcomes. In the D-multiple task, participants were asked to choose between the two options under the assumption that their selection would be applied a total of 100 times. In the D-single task, participants were asked to choose between the two options under the assumption that their selection would be applied only once to themselves. The participants’ eye movements were recorded while they performed the tasks. Behavioral results revealed that, compared with the D-single task, participants selected more choices correctly predicted by EV and EU theories, and took a longer time to make a decision in the D-everyone and D-multiple tasks. Furthermore, eye movement measurements revealed the following. (1) The scanpath patterns of the D-everyone task and D-multiple task were similar but different from those of the D-single task. (2) The depth of information acquisition and the level of complexity of information processing in the D-everyone task and D-multiple task was higher than that in the D-single task. (3) The direction of information search in the D-everyone task and D-multiple task was more alternative-based than that in the D-single task. (4) The eye-tracking measures mediated the relationship between the task and the EV-consistent choice. In summary, behavioral and eye movement results supported our hypotheses that participants were likely to follow an expectation strategy in the D-everyone and D-multiple tasks, whereas they were likely to follow a heuristic/non- expectation strategy in the D-single task. We found that expectation-maximization-based theories could capture the choice of an individual when making decisions for everyone and for self in a multiple-play condition but could not capture the choice of an individual when making decisions for self in a single-play condition. The evidence for the discrepancy between everyone and every one, which was first reported in our study, implied that the possible reason why expectation-maximization-based theories do not work is that a default compatibility between the full set (everyone) and the subset (every one) does not exist. Our findings contribute to an improved understanding of the boundaries of expectation-maximization-based theories and those of heuristic/non-expectation models. Our findings may also shed light on the general issue of the classification of risky decision-making theories.
