Effect of post-encoding emotion on recollection and familiarity for pictures

Although prior studies have examined the effect of post-encoding emotional arousal on recognition memory for words, it is unknown whether the enhancement effect observed on words generalizes to pictures. Furthermore, prior studies using words have showed that the effect of emotional arousal can be modulated by stimuli valence and delay in emotion induction, but it is unclear whether such modulation can extend to pictures and whether other factors such as encoding method (incidental vs. intentional encoding) can be modulatory. Five experiments were conducted to answer these questions. In Experiment 1, participants encoded a list of neutral and negative pictures and then watched a 3-min neutral or negative video. The delayed test showed that negative arousal impaired recollection regardless of picture valence but had no effect on familiarity. Experiment 2 replicated the above findings. Experiment 3 was similar to Experiment 1 except that participants watched a 3-min neutral, negative, or positive video and conducted free recall before the recognition test. Unlike the prior two experiments, the impairment effect of negative arousal disappeared. Experiment 4, where the free recall task was eliminated, replicated the results from Experiment 3. Experiment 5 replicated Experiments 1 and 2 and further showed that the impairment effects of negative arousal could be modulated by delay in emotion induction but not by encoding method or stimuli valence. Taken together, the current study suggests that the enhancement effect observed on words may not generalize to pictures.     

Hierarchical Structure and Cross-Cultural Measurement Invariance of the Norwegian Version of the Personality Inventory for DSM–5

The Personality Inventory for DSM–5 (PID–5) was created to aid a trait-based diagnostic system for personality disorders (PDs) in the Diagnostic and Statistical Manual of Mental Disorders (5th ed. [DSM–5]; American Psychiatric Association, 2013a American Psychiatric Association. (2013a). Diagnostic and statistical manual of mental disorders (5th ed.). Washington, DC: Author.[Crossref] , [Google Scholar]). In this study, we aimed to evaluate the Norwegian version of the PID–5 by examining its score reliability, hierarchical structure, congruency with international findings, and cross-cultural measurement invariance with a matched U.S. sample. For this purpose, 503 university students (76% females) were administered the PID–5. The Norwegian PID–5 showed good score reliability and structural validity from 1 to 5 factors. The 5-factor structure was generally congruent with international findings, and support for measurement invariance across the Norwegian and a matched U.S. sample was found. Conclusively, the results indicate that scores on the Norwegian PID–5 have sound psychometric properties, which are substantially comparable with the original U.S. version, supporting its use in a Norwegian population.

特征和结构信息对草图人脸识别的影响

在人脸认知研究的特征说、结构说和整体说的基础上,通过草图人脸与人脸相似程度主观评价的调查,发现五官位置、拓扑结构、五官比例、轮廓外形和五官外形等五个维度对人脸识别影响的权重依次减小,并且存在着多种显著的不同水平的交互作用。进而提出,五官位置和拓扑结构可组合成具体图形意义上的结构关系,这种结构关系将整体人脸分解成有序的特征集。     

PTSD在中国的研究进展

PTSD是近十年来在中国精神病学界逐渐引起重视的一种反应性精神障碍。随着国外对PTSD的深入研究以及中国心理卫生事业的发展,相关领域的学者开始从事这一方面的研究并取得了不少成就。文章对中国PTSD的流行病学、神经生物学基础、病因学以及诊断和治疗等各个方面的研究作了初步总结和探讨。     

审美心理素质教育模式探析

审美心理素质教育定位于受教育者人格的发展：其本质核心是感性的独立;其基本特征是情感的通融;其特殊功能是创造力的释放;其价值定向是生命的体验。本模式通过具体教育内容引发学生预期心理活动,养成相应的审美心理素质：在智育中展开认知活动,获得感性领悟;在德育中激发动机,内化情感体验;在体(劳)育中实践意志品质,感受生命潜能;在美育中获得审美策略,独立创造意象,这些审美心理素质的综合可实现完整人格的塑成。     

当代心理学发展的一种新取向--进化心理学

进化心理学是近年在西方心理学中出现的一种新的研究取向,目前仍没有一个明确的概念和系统的理论。其基本主张是：过去是理解心理机制的关键;功能分析是理解心理机制的主要途径;心理机制是在解决问题的过程中演化形成的;模块性是心理机制整体组织的特性;人的行为是心理机制和环境互动作用的结果。进化心理学的发展既有意义同时也存在局限。其意义是：其发展与当代科学发展趋势相一致;它的研究促进了对人性和心理的进一步思考。局限是：具有遗传决定论的倾向;方法论存在一定的缺陷,忽视了文化对进化的意义等等。     

Human echolocation: pitch versus loudness information

Blind persons emit sounds to detect objects by echolocation. Both perceived pitch and perceived loudness of the emitted sound change as they fuse with the reflections from nearby objects. Blind persons generally are better than sighted at echolocation, but it is unclear whether this superiority is related to detection of pitch, loudness, or both. We measured the ability of twelve blind and twenty-five sighted listeners to determine which of two sounds, 500 ms noise bursts, that had been recorded in the presence of a reflecting object in a room with reflecting walls using an artificial head. The sound pairs were original recordings differing in both pitch and loudness, or manipulated recordings with either the pitch or the loudness information removed. Observers responded using a 2AFC method with verbal feedback. For both blind and sighted listeners the performance declined more with the pitch information removed than with the loudness information removed. In addition, the blind performed clearly better than the sighted as long as the pitch information was present, but not when it was removed. Taken together, these results show that the ability to detect pitch is a main factor underlying high performance in human echolocation.     

加强我国卫生领域科研诚信建设的重要性

近几年来,我国的科研不端案例呈不断上升趋势.科技部、教育部、中国科学院,国家自然科学基金委员会、中国科学技术协会等部门或机构已发布了关于科研不端行为的处理规定,然而在我国卫生领域科研不端行为的处理和科研诚信建设方面尚未出台相关政策或指导意见.加强我国卫生领域的科研诚信建设具有重要意义.
