晚期正成分的时间-空间迁移模式在情绪调节发展研究中的应用

近二十年,使用认知神经科学手段探讨情绪调节成为了研究的热点。晚期正成分(Late Positive Potential,LPP)是情绪调节脑电研究中的一个典型成分,在不同的时间窗中分析LPP的波幅的变化及其优势激活脑区的迁移能够反映情绪调节加工过程中个体由对情绪刺激的感知到相应的认知调控过程的转变。LPP的时间-空间迁移模式被应用于情绪调节的发展研究,揭示从童年到青少年再到成年期个体情绪的潜在神经机制。研究者关注幼儿期、童年期、青少期、成人期个体在情绪调节加工过程中LPP波幅的变化及其时间-空间迁移模式特征,把不同年龄段个体情绪调节的发展特点与其大脑关键脑区(主要是前额叶)发育状况进行联系,为儿童身体发育和心理发展的主题提供更多的证据支持。未来的研究应加强对LPP在异常发展研究中应用,关注大脑发育与激素变化对LPP变化的影响,并加强对LPP调节效应的个体差异等问题的探讨。     

Experimental Tests of Risk Ladders in the Elicitation of Perceived Likelihood

Risk ladders have the potential to improve numeric judgments of low‐likelihood events by providing information about the likelihoods of comparison risks, thereby letting respondents make risk estimates “in context.” However, to date this tool has been studied systematically only in communication of risk, not in elicitation of perceived likelihoods. In three studies, we evaluated the benefits of risk ladders on the consistency, validity, and mean‐level accuracy of elicited likelihood judgments. When estimates for low‐likelihood hazards were elicited using different numeric response scales (e.g., “1 in x” and “x in 100,000”), scale type had a strong effect on the magnitudes of the elicited estimates, and viewing a risk ladder (Experiment 1) or comparison risks (Experiments 2 and 3) did not attenuate this effect of scale type. Similarly, we found no evidence that risk ladders or comparison risks improved the convergent validity of numeric estimates, as measured using correlations with risk ratings made on alternative scale types. Finally, viewing comparison risks tended to reduce gross overestimation of rare events, with relatively less change in estimates for mid‐likelihood and high‐likelihood hazards. This suggests that comparison risks can spread responses to cover a wider range of values but do not ameliorate scale effects. In the elicitation of numeric risk estimates, how you ask matters, even if you let people make estimates “in context” through the use of comparative risk information.

Cross-Cultural Competence: The Role of Emotion Regulation Ability and Optimism

Cross-cultural competence (3C) is critical for military personnel to understand and perform effectively in complex cultural environments and to interact with individuals from other cultures. The knowledge, skills, and abilities that make up 3C can result in clearer communication, build trust, and strengthen relationships in cross-cultural social contexts ( Selmeski, 2009 Selmeski, B. (February, 2009). Military Cross-cultural competence: Core concepts and individual development. Proceedings from the 7th Biennial Equal Opportunity, Diversity, and Culture Research Symposium. Patrick Air Force Base, FL. [Google Scholar]). This research investigated the role of emotional regulation and optimism in the development of 3C in military personnel. Results demonstrate that the ability to regulate emotions is positively related to 3C, both directly and through its effect on optimism.     

Theory of Mind and Sensitivity to Teacher and Peer Criticism Among Japanese Children

This study investigated sensitivity to teacher and peer criticism among 89 Japanese 6‐year‐olds and examined the connection between sensitivity to criticism and first‐order and second‐order theory of mind separately. Participants completed a common test battery that included tasks assessing sensitivity to criticism (teacher or peer condition), the Picture Vocabulary Test—Revised, and theory of mind tasks. The results showed that the children with better understanding of second‐order mental states rated their ability negatively after teacher criticism, but they were motivated to keep trying. This phenomenon was found under only the teacher condition, and peer criticism did not significantly affect children's response, irrespective of theory‐of‐mind level. Cognitive and social factors that may have contributed to the children's responses to criticism are discussed. Copyright © 2014 John Wiley & Sons, Ltd.     

The influence of motivational and emotional factors in mathematical learning in secondary education

IntroductionWhile motivation has, for decades, been investigated as a key component of academic learning and performance, academic emotions have often been left out of the scope of investigation. According to several researchers, mathematics learning seems to be particularly affected by students’ emotions.ObjectiveThis paper is aimed at characterizing the emotions and motivation of eighth grade students in a mathematical setting and highlighting the cluster of emotions–activity emotions vs outcome emotions–which best predict math value, math self-concept, behavioral engagement and math performance.MethodData were collected through questionnaires from 115 students and analyzed through means comparisons and linear regressions.ResultsResults indicated that eighth grade students give a relatively high value to mathematics have a positive mathematics self-concept and are moderately engaged in mathematical tasks. Regression analysis showed that mathematics value and behavioral engagement are better explained by activity emotions while mathematics self-concept and performance are better predicted by outcome emotions.ConclusionThe implications of these findings in terms of educational practices are discussed at the end of this study.     

The relationship between suppression and subsequent intrusions: the mediating role of peritraumatic dissociation and anxiety

Background and objectives: Although previous studies showed that thought and emotion suppression represent risk factors for intrusions development, the mechanisms that explain these relations were less explored. This study aims to examine the relationships between thought and emotion suppression and the symptoms of intrusion following the exposure to a trauma-related event. Moreover, we explored if these relationships would be mediated by peritraumatic state dissociation and state anxiety.

Design and methods: The trauma film paradigm was used and the participants were students (N?=?148) experimentally exposed to an aversive film to model a traumatic experience. Thought and emotion suppression were measured before the trauma exposure. After exposure, the participants completed scales for measuring state dissociation and state anxiety. Intrusive images and thoughts of the film were recorded in the subsequent week using an intrusion diary.

Results: Thought suppression predicted intrusive thoughts frequency, and this effect was mediated by the peritraumatic anxiety. State anxiety predicted both intrusive images and thoughts, while state dissociation only predicted intrusive images.

Conclusions: Intrusive images and intrusive thoughts are different phenomena and they are predicted by different variables. The practical implications of these results for posttraumatic stress disorder treatment and secondary traumatization are discussed.

Flashbulb memories of the Paris attacks

Flashbulb memories are vivid autobiographical memories of the circumstances where an individual first learns about emotionally significant public events. Our paper assesses whether these memories were triggered by the attacks of Friday 13 November 2015 in Paris. Two hundred and ninety‐one participants answered a web‐based questionnaire that assessed their memory of the circumstances in which they first learned of the attacks. The questionnaire also assessed vividness, rehearsal, emotion, surprise and novelty. The results showed substantial and vivid recall of the context in which the participants first learned of the event. This recall was associated with fair rehearsal, negative emotional valence, surprise, and novelty. Regression analysis showed that the flashbulb recall was predicted by negative emotion. Negative emotion seems to play a key role in the formation of flashbulb memories, at least those associated with the Paris attacks.     

The impact of emotional expressions on children’s trust judgments

Research on the development of selective trust has shown that young children do not indiscriminately trust all potential informants. They are likely to seek and endorse information from individuals who have proven competent or benign in the past. However, research on trust among adults raises the possibility that children might also be influenced by the emotions expressed by potential informants. In particular, they might trust individuals expressing more positive emotion. Indeed, young children’s trust in particular informants based on their past behaviour might be undermined by their currently expressed emotions. To examine this possibility, we tested the selective trust of fifty 4- and 5-year-olds in two steps. We first confirmed that children are likely to invest more trust in individuals expressing more positive emotion. We then showed that even if children have already formed an impression of two potential informants based on their behavioural record, their choices about whose claims to trust are markedly influenced by the degree of positive emotion currently expressed by the two informants. By implication, the facial emotions expressed by potential informants can undermine young children’s selective trust based on the behavioural record of those informants.
