Self processing in the brain: A paradigmatic fMRI case study with a professional singer

Understanding the mechanisms involved in perception and conception of oneself is a fundamental psychological topic with high relevance for psychiatric and neurological issues, and it is one of the great challenges in neuroscientific research. The paradigmatic single-case study presented here aimed to investigate different components of self- and other-processes and to elucidate corresponding neurobiological underpinnings. An eminent professional opera singer with profound performance experience has undergone functional magnetic resonance imaging and was exposed to excerpts of Mozart arias, sung by herself or another singer. The results indicate a distinction between self- and other conditions in cortical midline structures, differentially involved in self-related and self-referential processing. This lends further support to the assumption of cortical midline structures being involved in the neural processing of self-specific stimuli and also confirms the power of single case studies as a research tool.     

始成年期自我同一性发展特点及影响因素

Erikson将自我同一性看作是终生发展的过程并把18~25岁作为发展的关键时期, Arnett根据后现代社会的现实环境将这一阶段命名为“始成年期”。始成年期自我同一性对情感、工作、世界观等自我同一性发展领域的关注度相对青少年期更广泛与深入, 发展任务的繁杂使始成年期自我同一性的发展更具波动性, 并随着个体逐渐成熟而更多处于同一性的高级状态。后现代社会属性是始成年期自我同一性问题的根本, 原生家庭持续影响始成年期自我同一性的发展, 同时学校与工作单位这样的社会机构构成近端环境直接作用于始成年期自我同一性, 自主性在始成年期个体与其家庭及所处社会机构的交互作用中对自我同一性起到关键性调节作用。     

社会支持与道德敏感性：道德认同的中介作用

本研究依据社会信息加工理论探讨了感知社会支持对道德敏感性的影响,并基于社会认知模型探讨了道德认同内在化和表征化在其中的中介作用。对387名中国大学生进行问卷调查分析,结果表明感知社会支持显著正向影响道德敏感性,仅道德认同内在化在感知社会支持和道德敏感性间起中介作用。这一研究结果拓展了有关道德敏感性影响因素的研究,为增强个体道德敏感性提供了理论依据。     

同性恋认同发展的理论模型述评

本质论取向的阶段模型和社会建构论取向的影响因素模型是早期的同性恋认同发展理论,两者对性倾向是否为人类的本质属性产生了激烈的争论。当代发展心理学从生态化理论、毕生发展观、生命历程观出发试图对这两种研究取向进行整合,并提出了相应的模型。未来的研究应该注意同性恋认同发展多样性的特点,正确理解对外暴露在认同发展中的作用,并把纵向研究作为以后的研究方向。最后,提出了中国同性恋认同的特点和本土化研究的假设

MATCHING-TO-SAMPLE PERFORMANCE IN RATS: A CASE OF MISTAKEN IDENTITY?

Three rats had previously acquired a simultaneous matching-to-sample performance with steady and blinking lights. In training, the sample stimulus had always appeared on the middle of three horizontally arranged keys with the comparison stimuli on the side keys. In Experiment 1, the sample stimulus appeared on any of the three keys with the comparison stimuli on the remaining two. The matching-to-sample performance broke down with variable sample and comparison locations; the sample stimulus did not control responding to the comparison stimuli when it appeared on a side key, but it retained control when it appeared on the middle key (as in training). In Experiment 2, the rats were trained with the sample always on the left key. When the sample appeared on either of the trained locations (left or middle key), it retained control for both locations. When the sample then appeared on any of the three keys, as in Experiment 1, sample control did not transfer to the untrained location (right key). The experiments demonstrate that training with fixed sample and comparison locations may establish spatial location as an additional controlling aspect of the stimuli displayed on the keys; stimulus location had become part of the definition of the controlling stimuli. The rats' performance seemed best described as specific discriminations involving the visual stimuli and their spatial locations rather than as identity matching.     

Relevant identity

We begin to fill a lacuna in the relevance logic enterprise by providing a foundational analysis of identity in relevance logic. We consider rival interpretations of identity in this context, settling on the relevant indiscernibility interpretation, an interpretation related to Dunn's relevant predication project. We propose a general test for the stability of an axiomatisation of identity, relative to this interpretation, and we put various axiomatisations to this test. We fill our discussion out with both formal and philosophical remarks on identity in relevance logic.     

Overshadowing the Reminiscence Bump: Memories of a Struggle for Independence

We describe a study in which young and older groups of Bangladeshi participants recalled and dated autobiographical memories from across the lifespan. Memories were subsequently plotted in terms of the age of participants at time of encoding. As expected the reminiscence bump, preferential recall of memories from the period of 10 to 30 years of age, was observed. This was very marked in the younger group and but less so in the older group who also showed a second bump in the period 35 to 55 years of age. This second bump corresponded to the period of national conflict between Pakistan and the Bengalee people that resulted in the formation of an independent Bangladesh. It is proposed that both the reminiscence bump and later periods of unexpected rises in recall can be accounted for by the raised accessibility of sets of memories and this in turn is a product of the privileged encoding of highly self-relevant experiences.
