部分线索对记忆提取的影响:认知抑制能力的作用

在回忆时,以刚刚学过的部分项目作为提取线索,被试的回忆成绩反而比没有任何线索时的回忆成绩差,这一现象被称为部分线索效应。该效应通常被认为是抑制执行控制过程对非线索项目记忆表征强度抑制的结果。本研究以Stroop效应量(实验1)和工作记忆容量(实验2)为指标,从个体差异角度考察了认知抑制能力对部分线索效应的影响。结果发现,Stroop效应量与部分线索效应各指标呈显著负相关,Stroop效应量越小,部分线索效应各指标的值越大;工作记忆容量与部分线索效应各指标呈显著正相关,高工作记忆容量个体的部分线索效应各指标的值也更大。结果表明,认知抑制能力越强,部分线索对回忆的破坏作用越大,研究结果支持部分线索效应的提取抑制假说。     

抑郁的多基因遗传基础

抑郁具有复杂的、非孟德尔式的多基因遗传模式, 但是目前多数抑郁的遗传研究集中于考察单个候选基因, 不能全面揭示遗传因素的作用机制。近年来, 多基因遗传得分研究和基因−基因交互研究分别为抑郁的多基因累加效应和交互效应提供了新的证据。多基因不仅直接影响抑郁, 还通过与环境因素的交互作用影响抑郁的发生发展, 并且这一复杂交互作用存在性别差异。抑郁的内表型研究发现多基因可能通过认知因素、人格、压力荷尔蒙等间接影响个体的抑郁水平。未来研究应更加关注多基因与多种环境因素如何相互作用影响抑郁, 探索多基因遗传机制的性别差异, 考察多基因对抑郁影响随年龄的发展动态变化。     

论中国多元化医疗公正的选择

生命伦理学面对的最大的道德困惑是公正问题,其中最为尖锐的问题是生命权利与医疗公正.公正原则在实际医疗领域运用中存在着种种误区.公正观的多元化是现代社会包括现代医疗的必然结果,体现在医疗公正方面合理的伦理选择就在于在不同的医疗境遇中,使用不同的公正原则,从而选择现实的生命伦理学道路.     

Group-based trust and gender differences in China

Based on the established finding that there are gender differences in the type and use of social capital, we suggest that males and females also differ in the ways they engage in intra- and inter-group interactions. An experiment was conducted to explore how gender affects group-based trust in China. The results demonstrated that male participants were significantly more trusting of unknown partners than were female participants. In addition, we found that male participants' high trust toward unknown partners had a strong relationship with expectation of reciprocity from their partners while female participants' low trust toward unknown partners was associated with a strong fear of exploitation from their partners. These findings were examined in the context of a discussion of gender differences in social capital.     

Body Dissatisfaction in College Women and Their Mothers: Cohort Effects, Developmental Effects, and the Influences of Body Size, Sexism, and the Thin Body Ideal

A study of body dissatisfaction, as measured by the Figure Rating Scale (Stunkard, Sorenson, & Schlusinger, 1983) and the Body Esteem Scale (Franzoi & Shields, 1984), in 75 college women and their mothers indicated that both daughters and mothers experienced body dissatisfaction. When body size was statistically controlled, either no difference was found between the groups or daughters were found to have greater body dissatisfaction than mothers. The results supported the hypotheses that (1) there are generational differences in body dissatisfaction, (2) both cohort and developmental effects contribute to these differences, and (3) that a developmental effect (mothers' greater body size) may obscure a cohort effect (daughters' greater exposure to the thin body ideal). Body dissatisfaction measures based on the mothers' retrospective ratings of how they felt at their daughters' age were consistent with these hypotheses. Relationships between body dissatisfaction and the Sociocultural Attitudes Toward Appearance Questionnaire (Heinberg, Thompson, & Stormer, 1995) were stronger and more frequent for daughters than for mothers and for the Internalization Scale than for the Awareness Scale. Relationships between the Ambivalent Sexism Inventory (Glick & Fiske, 2001) and body dissatisfaction were stronger for mothers than for daughters and for Benevolent Sexism than for Hostile Sexism.     

Predictors and outcomes of job search behavior: The moderating effects of gender and family situation

This study explored differences in the antecedents and consequences of job search behavior depending on gender and family situation in a large, nationwide sample of the Dutch population. Using Ajzen’s (1991) theory of planned behavior (TPB), we found no gender differences in the antecedents of job seeking. However, family situation did affect the relations in the TPB, such that personal attitude was a slightly weaker, and perceived social pressure a stronger predictor of job seeking for individuals with families than for singles. Concerning the consequences, job search behavior significantly predicted the chances of finding (new) employment, but not job satisfaction in the new job and the level of agreement between the obtained and wanted job.     

The spiritual well-being questionnaire: Testing for model applicability, measurement and structural equivalencies, and latent mean differences across gender

Fisher (1998) proposed a spiritual well-being model, comprising primary factors for the domains of personal, communal, environmental and transcendental well-being, that cohere to form a single higher order or global spiritual well-being dimension. In line with this model, Gomez and Fisher (2003) published the Spiritual Well-Being Questionnaire (SWBQ), with scales for measuring personal, communal, environmental and transcendental spiritual well-being. This study used multi-group confirmatory factor analysis (CFA) to examine gender equivalencies of the measurement and structural models of the SWBQ, and the latent mean in the four SWBQ factors. A total of 3101 females and 1361 males, with age ranging from 15 to 32 years, completed the SWBQ. The statistical fit results supported the invariance of the measurement model, and some aspects of the structural model. The practical fit indices results provided support for the invariance of both the measurement and structural models. The results also showed little gender differences. Together, these findings support gender equivalencies for the SWBQ.     

Born lucky? The relationship between feeling lucky and month of birth

Research suggests that season of birth is associated with several psychiatric and neurological disorders, and also with adult monoamine neurotransmitter turnover. Personality traits are modulated in part by neurotransmitters; and population studies show season of birth variations in adult personality traits such as novelty seeking. Also, neurotransmitters are involved in suicidal behavior; and studies have found season of birth associations with suicide methods. The present general population survey was conducted via the Internet, and involved 29,584 self-selected participants (51.6% women) from 67 countries. For those born in the UK (75.6%), we investigated the relationship between season of birth, the participant’s belief in being a lucky person, and personality attributes related to this belief. In both genders and in all age groups, birth during the summer half-year was associated with significantly higher belief in being lucky, as compared to birth during the winter half-year, with a maximum around birth in May and a minimum around birth in November. Women scored significantly higher on listening to intuition and employing techniques to improve intuition, in perseverence, believing in positive long-term outcomes, and chatting to strangers. Men scored significantly higher on feeling lucky, not worrying or dwelling on failures, and expecting good things in life.     

儿童类别学习中知识效应的年龄差异

采用特征主题的类别学习实验范式,考察了儿童类别学习中知识效应的年龄差异。63名小学4年级学生(年龄范围9～10岁)、65名小学6年级学生(年龄范围11～12岁)和77名初中2年级学生(年龄范围13～14岁)参加了本实验。结果表明:当类别特征能够在已有知识的基础上形成主题时,3个年龄组儿童类别学习的轮次和错误数均显著下降,而且主题突出时,这种趋势更加明显;在统一主题条件下,小学4年级、小学6年级和初中2年级3个年龄组儿童类别学习的轮次和错误数依次减少;而在无主题和突出主题条件下,3个年龄组儿童类别学习的成绩无显著差异。
