Abstract： Mainstream theorists in risky decision-making have developed various expectation theories with the ambitious goal of capturing everyone’s choices. However, ample evidence has revealed that these expectation theories could not capture every individual’s (“every one’s”) actual risky choice as descriptive theories. With doubts about the default compatibility between everyone (full set) and every one (subset), we used an eye-tracking technique to explore whether a theory for everyone would work well for every one. We found that expectation 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. Our findings contribute to a better understanding of the boundaries of expectation theories and those of heuristic/non-expectation models, and may shed light on the general issue of the classification of risky decision-making theories.

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.

Abstract：
Developmental dyslexia is a major type of learning disabilities. It severely hinders the development of cognition, emotion and social adaptability. Writing is closely related to reading，and individuals with dyslexia usually manifest writing difficulty. At the behavioral level, dyslexics exhibit impaired writing quality, speed and pauses, compared to typical readers, involving the central and peripheral components of writing. At the neural level, neuroimaging studies demonstrated that dyslexics showed altered functional and structural connectivity in brain regions associated with linguistic and motor processes of writing. Writing is greatly related to reading in Chinese. The study of writing deficit would have values for developing the unique diagnosis and treatment strategies for Chinese dyslexia. " "

Abstract： Sense of agency (SoA) refers to the feeling of controlling one's own actions and, through them, events in the external world when performing voluntary actions. Intention of action and sensory feedback are two core components that constitute the sense of agency. However, the cognitive neural mechanism underlying the influence of these two components on SoA is unclear. We propose to explore the feedforward effect of action intention and the feedback effect of sensory feedback on SoA. The magnetoencephalography technology, which is of high temporal and spatial resolution, is employed to extract the time-space characteristics of sense of agency at the fronto-parietal network in both the time windows of action-outcome and after-outcome. The elucidation of this cognitive neural mechanism of SoA will contribute to our understanding of the generation and aftereffects of human actions; furthermore, it will provide implications for the demarcation of behavioral responsibilities in moral and legal settings, and for the clinical diagnoses of related mental diseases.

Abstract： Creativity is an interwoven system, encompassing individuals, groups, society, culture, etc. Since creativity is a system, the cultivation of creativity should also be systematic. We integrated some creativity-relevant theories to generate practical advice on the challenges of supporting creativity within the classroom. Based on earlier research on creativity, we put forth the “Butterfly Theory of Nurturing Creativity” to give a bird’s eye view of nurturing creativity. In this theory, the core and premise of being creative are to have creative impulses or creative dynamics (i.e., dynamic systems). We summarized the conditions supporting the dynamic systems into “two forewings” named capability and vitality (i.e., the support system). At the level of capability, creativity calls for general cognitive ability, multimethod enlightenment, attention to metacognition, and efficient knowledge information management. At the level of vitality, creative dynamics also relies on the satisfaction of basic psychological needs, the healthy development of personal traits, and reasonably supportive social interaction in an inclusively social and cultural environment. Besides, if an individual wants to fly freely in a creative life, he also needs “two hindwings” (conducting daily creative thinking and problem solving; forming creative habits and a creative personality) that are constantly improved in daily life to adjust the balance (i.e., regulating system). People who are creative show motivation to make novel and appropriate products for their domains of interest. Creativity cannot be taught unless teachers find ways to intrigue their students’ creative impulses. Intrinsic motivation, like interest, is the greatest autonomous motivator. The key topics of this paper are to find what the essence of interest or fun is and how to raise it. Combining theory with practice, this paper also shows a general way to activate fun or interest in the classroom.

Abstract： 理清“一带一路”沿线国家或地区的民心特点，并找到有效的合作交往模式，是关系到国家战略实施的重大问题。但是，由于地域辽阔、民族众多，且地缘政治、经济、文化因素（如原苏联影响、欧美国家殖民、宗教传统等）异常复杂，传统的分析方法往往难以奏效。该研究结合文化心理学和大数据分析技术，利用社交媒体Twitter数据来分析“一带一路”沿线国家或地区的自我表征特点（独立性或个人主义），并建立自我表征与社会信任（普遍信任、特殊信任）的预测模型，以探究与“一带一路”沿线国家或地区合作交往的行为模式，即：自我表征是独立，还是互依；人际关系偏好是陌生人之间的普遍信任，还是熟人间的特殊信任。结果表明，“一带一路”沿线国家或地区在自我独立性这一个人主义文化指标上存在较大的变异，且主要受欧美国家殖民历史和当地宗教传统的影响；此外，针对陌生人、外国人的普遍信任与针对家人、熟人的特殊信任，可以通过个人主义指标来预测。总之，“一带一路”沿线的文化是多样的，可以通过社交媒体产生的海量语料库快速计算其个人主义指标，并以此来建立自我表征与社会信任的预测模型。该研究为分析“一带一路”战略区域的“民心”特点、探索当地合作交往的行为模式提供了新的技术路径。
