抑郁症:一种进化心理学的视角

探讨了抑郁症的进化机制。由进化机制支配的依恋和社会地位行为可能是某些严重抑郁症的基础,尤其是与长期压力相关的抑郁症。虽然抑郁症有不同的性质,但某些核心症状是为了调节行为、情绪以及传达对威胁的敏感性而进化形成的,如行为退缩、低自尊、快感丧失等。     

Effects of the Interaction Between Reaction Component of Personal Need for Structure and Role Perceptions on Employee Attitudes in Long‐Term Care for Elderly People1

This study examined the interaction of reaction component of personal need for structure (reaction to lack of structure, RLS) and role perceptions in predicting job satisfaction, job involvement, affective commitment, and occupational identity among employees working in long‐term care for elderly people. High‐RLS employees experienced more role conflict, had less job satisfaction, and experienced lower levels of occupational identity than did low‐RLS employees. We found individual differences in how problems in roles affected employees' job attitudes. High‐RLS employees experienced lower levels of job satisfaction, job involvement, and affective commitment, irrespective of role‐conflict levels. Low‐RLS employees experienced detrimental job attitudes only if role‐conflict levels were high. Our results suggest that high‐RLS people benefit less from low levels of experienced role conflicts.     

Bridging the divide: openness in adoption and postadoption psychosocial adjustment among birth and adoptive parents

Using 323 matched parties of birth mothers and adoptive parents, this study examined the association between the degree of adoption openness (e.g., contact and knowledge between parties) and birth and adoptive parents' postadoption adjustment shortly after the adoption placement (6 to 9 months). Data from birth fathers (N = 112), an understudied sample, were also explored. Openness was assessed by multiple informants. Results indicated that openness was significantly related to satisfaction with adoption process among adoptive parents and birth mothers. Increased openness was positively associated with birth mothers' postplacement adjustment, as indexed by birth mothers' self-reports and the interviewers' impression of birth mothers' adjustment. Birth fathers' report of openness was associated with their greater satisfaction with the adoption process and better postadoption adjustment.     

Factor analysis of the Revised Illness Perception Questionnaire in adults with atopic dermatitis

The objective of this study was to examine the psychometric properties of the revised Illness Perceptions Questionnaire (IPQ-R) in adult participants with atopic dermatitis (AD). Two hundred and eighty-four participants who had a GP or dermatologist confirmed diagnosis of AD completed the IPQ-R. The factor structure of the IPQ-R was examined using confirmatory (CFA) and exploratory factor analysis (EFA). The results of the CFA did not indicate a good comparative fit with the IPQ-R subscales, while the EFA and a fixed six-factor principal components analysis largely replicated the original factor structure of the IPQ-R. The existence of the acute/chronic and cyclical timeline dimensions, and the illness coherence subscale was most strongly supported, while all items of the consequences and emotional representation subscales consistently loaded onto one factor. The EFA for causal attributions did not produce a stable solution. The findings indicate that although the factor structure of the IPQ-R was not confirmed in the sample of patients with AD using CFA, it was partly reproduced using EFA. Overall, the results suggest that in patients with AD the IPQ-R, in particular the consequences and emotional representations subscales, should be employed and interpreted with care.     

The high-hurdle technique put to the test: Failure to find evidence that increasing loading times enhances data quality in Web-based studies

Two Web-based experiments examined the usefulness of artificially delaying the loading of the first page of the study. The idea pursued in this technique is to filter out less-motivated respondents through a higher respondent burden in the form of waiting time. Participants who remain in the study despite having had to wait for the first page of the study to appear on the screenare expected to be more highly motivated, and thus to produce data of higher quality. In both experiments, as expected, the longer the loading time, the lower the likelihood of people responding to the study. However, contrary to expectation, the dropout rate and quality of data were independent of the loading time. Therefore, artificially delaying the loading of the first page of the study is counterproductive.

刺激持续时间对注意瞬脱影响的实验分离现象

通过三个实验,研究了注意瞬脱效应以便深入理解注意时间维度上的特性。实验一针对注意瞬脱效应（简称AB效应）和刺激持续显示时间（简称ED）之间的关系,发现SOA或者ED的延长能减小AB效应。实验二的结果再次证明ED的延长能减小AB效应,并且发现ED延长并没有伴随着对目标的加工速度的加快。实验三发现在目标与干扰项没有显著的特征差异时,AB效应随着ED延长而减小的现象消失了,即ED对AB效应的影响出现了实验性的分离。同时还证明突出显示可以通过加快对目标的反应速度来显著的减小AB效应,而且ED因素只有在目标具有突出的视觉特征时才能改变AB效应。
