投资决策进化心理学的研究：预期的私人资金分配和父母对子女的差异性精力投入

投资决策的进化心理学研究着眼于辨认人类获得进化适应的特定环境中经常出现的典型性风险,探寻为了应对这些风险而进化出的信息处理机制,并验证现时的社会因素和个体因素对这些心理机制的激活或抑制作用。在研究一中,被试预测了与自己同龄的男人或女人如何分配一笔中彩的奖金给自己和其他可能的受益人。研究发现：（1）钱数的分配大体由亲缘关系的疏密程度决定;（2）两性被试都假想男性比女性更慷慨,但实际上男性表现得更自利;（3）女性被试预测男性中奖人的金钱分配比男性被试预测女性中奖人的金钱分配更为准确;（4）女性被试的受益人更多,分享的社会范围更广。研究二探讨了父母对子女投入精力的不同取决于家庭的相对财富而非绝对财富的进化心理学假说。用哺乳与否和生育间隔期为测量指标,研究结果显示：（1）家庭实际收入影响父母对子女的总投入;（2）与邻里家庭相比,父母对于自己家庭相对收入的认知影响了对子女有别的差异性精力投入。基于男性普遍在财富和生育数量上比女性有更大的变异度,投资儿子比投资女儿更具博弈性。两项研究表明,人类的理性决策既受限于社会关系又适应于相对的财富状况

The developmental pathways leading to pattern recognition, joint attention, language and cognition

According to the functional/emotional hypothesis, the core capacities necessary for cognitive and language development, such as pattern recognition, joint attention, and intention reading, are downstream effects of more basic processes having to do with early patterns of affect signalling. In this paper, we present preliminary research that tests the functional/emotional hypothesis. The data set consists of profiles of the emotional functioning of infants and young children at ages 0-3, 4-5, 6-9, 10-14, 15-18, 19-24, 25-30, and 31-42 months. Data were collected on a representative population of 1640 children across the US. Results of this preliminary research point to expected correlations between the development of affective signalling and pattern recognition, joint attention, and intention reading. However, we acknowledge that this is only the first step in providing supportive evidence for the functional/emotional hypothesis. Further research is needed to establish causal connections between affective signalling and the core capacities necessary for cognitive and language development.     

Irrational Beliefs as Predictors of Emotional Adjustment after Divorce

The goal of this study was to analyze the role of irrational beliefs and other mediating variables in emotional adjustment after marital separation. Self-esteem and attachment to the ex-spouse were chosen as indicators of emotional adjustment. For this purpose several mediation centres and associations for separated people took part in the project. The results showed that irrational beliefs, as well as length of conflict during marriage, time since divorce and desire of contact with the former spouse, are good predictors of emotional adjustment. It has been suggested that Rational-Emotive-Behavior Therapy can be used in the treatment of divorced people.     

Spirituality and the Health of College Students

Objectives  The purpose of this study was to examine the relationship between spirituality and health risks of college students. Methods  Undergraduate students enrolled in Personal Health and Wellness classes at The University of Tennessee were selected to participate in the study. Two-hundred twenty-one students were administered two instruments: The College Student Appraisal of Risks Survey (The CARS) and the Spirituality Scale (SS). Results  Significant relationships between self-reported levels of spirituality and the health of college students were indicated during the study. Conclusions  College students integrating a spiritual component while processing decisions about risks that could negatively affect their health experienced better health outcomes. The significance of the study is that this research is an important step toward understanding the role that spirituality plays in the various dimensions of health in young adults.

IS MATCHING INNATE?

Experimentally naive mice matched the proportions of their temporal investments (visit durations) in two feeding hoppers to the proportions of the food income (pellets per unit session time) derived from them in three experiments that varied the coupling between the behavioral investment and food income, from no coupling to strict coupling. Matching was observed from the outset; it did not improve with training. When the numbers of pellets received were proportional to time invested, investment was unstable, swinging abruptly from sustained, almost complete investment in one hopper, to sustained, almost complete investment in the other-in the absence of appropriate local fluctuations in returns (pellets obtained per time invested). The abruptness of the swings strongly constrains possible models. We suggest that matching reflects an innate (unconditioned) program that matches the ratio of expected visit durations to the ratio between the current estimates of expected incomes. A model that processes the income stream looking for changes in the income and generates discontinuous income estimates when a change is detected is shown to account for salient features of the data.     

Emotional, external, restrained eating and overweight in Dutch adolescents

The purpose of this study was to determine how emotional, external and restrained eating behavior and other health-related lifestyle factors were associated with being overweight in adolescents. Moreover, demographic and ethnic differences in eating behavior have been examined. The respondents were 10,087 Dutch adolescents aged 11-16 years (M= 13.0, SD= 0.8). Self-reported eating behavior was measured with the DEBQ. Health-related lifestyle was determined by physical activity, breakfasting, fruit consumption and snacking. High restrained, and low external eating were positively associated with being overweight, whereas no significant association between emotional eating and being overweight was found for girls, and a negative association for boys. Adolescents who ate breakfast on a daily basis were less likely to be overweight than those who ate breakfast irregularly or never. Being overweight was positively associated with fruit consumption for girls and negatively with physical activity for boys.     

Regulating anger and sadness: an exploration of discrete emotions in emotion regulation

Do emotion regulation processes vary as a function of discrete emotions? Focusing on anger and sadness, this study examined: (a) the strategies that men and women use to regulate each emotion, (b) the extent to which strategies differ in their use and effectiveness, and (c) the relationship between effective regulation of these emotions and social functioning. One hundred ninety participants described recent situations that evoked anger and sadness and how they regulated each emotion. Emotion regulation attempts for anger and sadness differed to some extent in both use and effectiveness. In addition, effective regulation of each emotion was associated with different aspects of social functioning. Effective anger regulation was associated with constructive conflict resolution style, and effective sadness regulation was associated with positive social relations. The findings suggest that global approaches to studying emotion regulation may be limited and emphasize the importance of moving toward a discrete emotions framework.     

企业管理者的情绪智力、自我效能感、成就动机研究

采用问卷法对211名企业管理者的情绪智力、自我效能感、成就动机的特征及它们与企业管理者绩效的关系进行了研究。研究表明,不同管理层级、不同管理岗位、不同地区的企业管理者的情绪智力、自我效能感、成就动机存在显著差异;企业管理者的年龄、性别、文化水平、所在企业的性质和规模对情绪智力、自我效能感、成就动机没有显著影响。研究还表明,情绪智力、自我效能感、成就动机对高层、中层、基层企业管理者的绩效有不同的预测力。     

情绪状态对大学生道德判断能力的影响

采用道德判断测验(MJT中文版),以300名大学生为被试,考察了情绪状态对大学生道德判断能力的影响。结果发现:(1)大学生道德判断能力的年级差异显著;(2)情绪状态对大学生道德判断能力具有显著影响,快乐状态下的道德判断能力高于悲伤状态,这与国外的研究结论正好相反;(3)道德判断任务的自我相关性对大学生道德判断能力的影响不显著。
