有性Penna模型:进化心理学的新工具

进化心理学家以进化论为基础,使用了许多不同的方法来研究人类的心灵。这些方法都有共同的缺陷,即无法直接对提出的假设进行验证,对复杂的系统进行研究难度很大,计算机模拟的方法可在一定程度上修补该问题。有性Penna模型能反映有性生殖种群的进化特点,能反映环境对生物进化的影响,通过该模型来模拟人类进化历程,则可以检验某一心理机制是否是适应的,它是研究生物进化的有力工具。本文在综述已有研究成果的基础上提出用有性Penna模型对进化心理学关于进化轨迹的假设进行验证的构想,并在此基础之上提出了用该模型进行研究的基本框架。     

Perceived interpersonal sources of life satisfaction in Chinese and American students: Cultural or gender differences?

This study evaluated cultural and gender differences in perceived interpersonal sources of life satisfaction between 341 Chinese and 222 American college students. Comparative analyses indicated overall lower life satisfaction in Chinese, than in Americans. However, Chinese, compared to Americans, reported greater life satisfaction derived from perceived sources involving the self, parents, teachers and peers. Results of regression analyses indicated that, for both Chinese and Americans, the self and parents were unique sources associated with life satisfaction. However, for Americans, close friends also emerged as an additional unique source. When gender differences were examined, additional nuances were found within each cultural group. Thus, some evidence for both cultural and gender differences in perceived interpersonal sources of life satisfaction across Chinese and Americans was found. Some implications of the present findings are discussed.     

Cultural Identity and the Expression of Depression: A Social Identity Perspective

The present research interrogates the greater tendency for Chinese people to somaticize depression relative to Westerners. Drawing from a social identity perspective, three studies were conducted examining the role that cultural norms play in symptom expression. In an initial study, we confirmed greater somatization, minimization of distress and suppression of emotional expression among Chinese participants compared with Australians (Study 1). Asian normative expectations of collectivism moderated these effects such that somatization was higher among those who endorsed collectivism norms, but only among Chinese participants. Studies 2a and 2b found that only when Asian participants identified strongly with Asian culture did collectivism norms predict somatic symptoms. These findings have implications for practitioners working with people from Asian cultures, highlighting that it is not culture per se, but the endorsement of normative expectations in the context of strong identification with cultural groups that predicts which symptoms of depression are emphasized.

Gratitude and Athletes’ Life Satisfaction: The Moderating Role of Mindfulness

Life satisfaction is a critical index of well-being and is well documented in the literature as a means of protecting athletes from stress. However, minimal research has focused on the factors that contribute to life satisfaction in sports. Accordingly, we adopted the positive psychology perspective and proposed that gratitude would relate to athletes’ life satisfaction. Additionally, we further suggested that mindfulness would strengthen the relationship between gratitude and athletes’ life satisfaction. Athletes completed measurements, and the results, which indicated that athletes with higher levels of gratitude exhibited increased life satisfaction when they had higher levels of mindfulness, supported our expectations. The implications and applications are discussed in terms of mindfulness.     

Electrophysiological and behavioral evidence reveals the effects of trait anxiety on contingent attentional capture

Few studies have investigated the effects of anxiety on contingent attentional capture. The present study examined contingent attentional capture in trait anxiety by applying a rapid serial visual presentation (RSVP) paradigm during electroencephalographic recording. Overall, the behavioral and electrophysiological results showed a larger capture effect when a distractor was the same color as the target compared to when the distractor was not of the target color. Moreover, high-anxiety individuals showed a larger N2pc in the target colored distractor condition and nontarget colored distractor condition compared to the distractor-absent condition. In addition, the reaction time was slower when distractors were presented in the left visual field compared to when they were in the right visual field. This pattern was not seen in low-anxiety individuals. The findings may indicate that high-anxiety individuals allocate attention to the target less efficiently and have reduced suppression of distractors compared to low-anxiety individuals who could suppress attention to the distractors more efficiently. Future work could valuably investigate the consequences of such differences in terms of benefits and disruption associated with attentional capture differences in a range of anxious populations in different risk monitoring situations.     

Self-concept integration and differentiation in subclinical individuals with dissociation proneness

Dissociative pathology is characterized by an altered sense of self. Still, it remains unclear (a) whether the altered sense of self is also associated with non-pathological dissociation as well and (b) whether this potential association is an intrinsic connection or a consequence of other related constructs, including childhood trauma. This study addresses this question by examining how self-concept organization may differ among individuals with different levels of dissociation proneness. The structure of self-concept was operationalized by various indexes of self-concept integration and differentiation. Results showed that individuals high in dissociation proneness have lower self-concept clarity and compartmentalize self-aspects with more polarized evaluations. Notably, the association between dissociation proneness and evaluative self-compartmentalization held after controlling for childhood trauma, anxiety, and depression. This characteristic self-concept organization can be an attribute of non-pathological dissociation.     

Visual feature learning in artificial grammar classification

The Artificial Grammar Learning task has been used extensively to assess individuals' implicit learning capabilities. Previous work suggests that participants implicitly acquire rule-based knowledge as well as exemplar-specific knowledge in this task. This study investigated whether exemplar-specific knowledge acquired in this task is based on the visual features of the exemplars. When a change in the font and case occurred between study and test, there was no effect on sensitivity to grammatical rules in classification judgments. However, such a change did virtually eliminate sensitivity to training frequencies of letter bigrams and trigrams (chunk strength) in classification judgments. Performance of a secondary task during study eliminated this font sensitivity and generally reduced the contribution of chunk strength knowledge. The results are consistent with the idea that perceptual fluency makes a contribution to artificial grammar judgments.     

Shedding Light on the Relationship Between Personal Standards and Psychopathology: The Case for Contingent Self-Worth

Previous research has revealed some puzzling inconsistencies in the relationship of Personal Standards (PS) to measures of psychopathology. This study was designed to explore the hypothesis that setting high Personal Standards will relate to psychopathology only when meeting these standards is a necessary condition for a sense of self-worth. We generated items that reflected a sense of conditional self-worth based on the meeting of Personal Standards and named this measure the Contingent Self-Worth Scale (CSWS). Factor analysis of the CSWS and the PS subscale of the Multidimensional Perfectionism Scale yielded three types of Personal Standards: Pure Personal Standards," Success-Based Self-Worth," and Activity-Based Self-Worth." Two of the original PS items did not load on the Pure Personal Standards scale. Correlational analyses revealed that Pure Personal Standards was related to measures of adaptive outcome whereas both measures of Contingent Self-Worth were related to more maladaptive functioning, although with some small differences. We call for further research to explore the relationship of PS to the construct of perfectionism.     

Provider management of child stress behavior in family day care facilities: scaffolding for learning and development by developmentally appropriate practice

Six children (5 boys, 1 girl; aged 36-60 months) participated in this qualitative study. Each child was enrolled in a different family child care facility. The authors rated the child care providers in 3 of the facilities as using developmentally appropriate practices (DAP) most of the time and rated the providers in the 3 other facilities as rarely or never using DAP. They also examined provider management of children's stress behaviors. The authors observed less active and passive stress behaviors in the high-DAP facilities than in the low-DAP facilities. The authors discuss the results with regard to the distinctively different day care culture found in high-DAP facilities versus low-DAP facilities and the implications for practice.
