信息反馈不一致导致习得无助机制的实验研究

研究以90名大学生为被试,探讨认知活动中,信息反馈不一致性和操作成绩评价反馈导致大学生无助现象的机制。结果表明:认知活动中,信息反馈不一致,损害了被试的认知和情绪,对动机的损害没有达到显著性水平;实验中是否给予被试操作成绩评价,对被试的动机、认知和情绪影响不显著。说明在认知活动中,信息反馈不一致,是导致习得无助的关键因素,是否对被试的操作成绩给予评价反馈,不会导致习得无助,验证了习得无助的信息加工理论模型。实验也表明,信息反馈不一致不会形成被试反应性的抑郁。     

The Neural Bases of Placebo Effects in Pain

Abstract— Placebo effects are beneficial effects of treatment caused not by the biological action of the treatment but by one's response to the treatment process itself. One possible mechanism of placebo treatments is that they create positive expectations, which change one's appraisal of the situation and may thereby shape sensory and emotional processing. Recent brain-imaging evidence suggests that placebo-induced expectations of analgesia increase activity in the prefrontal cortex in anticipation of pain and decrease the brain's response to painful stimulation. These findings suggest that placebo treatments can alter experience, not just alter what participants are willing to report about pain. To the extent that they involve neural systems mediating expectancy and appraisal, placebo effects in pain may share common circuitry with placebo effects in depression, Parkinson's disease, and other disorders.     

数学学习障碍儿童问题解决的表征研究

本研究以小学四年级学生为被试,采用口语报告法探讨论了数学学习障碍儿童问题解决的表征情况。研究发现：数学学习障碍儿童问题解决的表征时间较短;数学学习障碍儿童问题解决的表征类型单一;数学学习障碍儿童问题解决的表征缺乏有效性。     

Distinguishing Hope from Optimism and Related Affective States

Three studies examined the conceptual and psychological differences between hope and related mental states. In Study 1, participants provided definitions of hope as well as optimism, want, desire, wish, and the non-anticipatory state of joy; in Study 2, participants wrote about a time when they had experienced each of these states. These definitions and stories were coded for a number of psychological features that were then used to distinguish the different states. Study 3 mapped the differences among the six mental states into a multidimensional conceptual space. Overall, hope is most closely related to wishing but distinct from it. Most important, hope is distinct from optimism by being an emotion, representing more important but less likely outcomes, and by affording less personal control. The importance of combining a folk-conceptual perspective with a more traditional analysis of appraisal for understanding differences among psychological constructs is discussed.

认知评价对主观情绪感受和生理活动的作用

围绕认知评价对情绪的作用, 针对传统认知评价实验方法的缺陷, 本研究改进认知评价的操作方法, 以情绪片段为实验材料, 以事先的评价背景替代与观看同步的评价策略, 以生理指标与情绪自评反映情绪变化, 考察41名大学生的认知评价对负性情绪的影响。结果发现, 持有利于情绪调节评价的个体, 负性情绪感受降低, 皮肤电反应减弱, 但心率无变化。研究表明, 认知评价影响个体的主观情绪体验, 并在一定程度上抑制负性情绪所致的生理唤起的增高。     

Maternal Appraisal Styles,Family Risk Status and Anger Biases of Children

The present study investigated the relationship between maternal appraisal styles, family risk status, and anger biases in children. Participants included 90 mothers and their children between 3–6 years of age. Eighty families were followed up 1 year later. Maternal appraisal styles were assessed via a naturalistic story-reading method, and Time 1 and Time 2 emotion biases included teacher ratings of anger and aggression, peer ratings of anger, as well as classroom and playground observations of anger. While discussing ambiguous stories with their children, mothers with higher scores on the family risk index utilized more hostile appraisals and fewer prosocial appraisals in their explanations. A higher proportion of hostile-to-prosocial appraisals was also related to higher-risk family status. Prosocial appraisals by mothers were inversely correlated with childrens anger biases at school. When the appraisal balance in mothers talk favored hostile appraisals, children tended to show higher levels of anger biases evidenced at school. Finally, a hostile balance of maternal appraisals was found to predict change in childrens anger biases in the school with different effects in high- and low-risk families.     

Gender Differences in Cognitive Vulnerability to Depression and Behavior Problems in Adolescents

This study assessed gender differences in cognitive variables as an explanation for gender differences in depression and behavior problems; 856 adolescents (491 females and 365 males), aged 14–17, completed the Irrational Beliefs Scale for Adolescents, the Social Problem Solving Inventory—Revised Short Form, the adolescent version of the Burnett Self-Talk Inventory, and the Youth Self Report. Female adolescents lower levels of positive thinking and higher scores on negative problem orientation, need for approval and success, and self-focused negative cognitions partially mediated gender differences in depressive symptoms. Males higher scores on justification of violence beliefs and the impulsivity/carelessness style of problem solving partially accounted for differences in delinquent behavior. The influence of need for approval and success on depressive symptoms was higher among adolescents at ages 14–15 than among older adolescents. Justification of violence did not influence delinquent behavior among girls at age 14–15.     

Cultural Competence in Interdisciplinary Collaborations: A Method for Respecting Diversity in Research Partnerships

There is growing recognition of the need by funding agencies, universities, and research units for interdisciplinary research to tackle complex societal problems that cannot be adequately addressed by single disciplines alone. Interdisciplinary collaboration capitalizes on a diversity of perspectives and practices that each discipline offers in hopes of providing innovative solutions to multifaceted problems. However, for interdisciplinary work to be effective, members of the collaboration must recognize that cultural differences exist between and within disciplines. This paper conceptualizes disciplines as cultural groups and advocates for culturally competent practices to facilitate interdisciplinary research and practice. Specifically, each participant in interdisciplinary collaborations must value diversity, develop the capacity for self-assessment, work towards understanding one's own disciplinary culture, and be sensitive to the dynamics inherent when cultures interact. Additionally, members of any interdisciplinary endeavor must be cognizant of power dynamics at play and avoid such things as tokenism, informal hierarchies, and disciplinary policing. Through awareness of one's own disciplinary culture and sensitivity to others, interdisciplinary research and practice may provide creative solutions to important problems.
