Integration,unintegration, disintegration: an introduction

This introduction to the two papers that follow by Anne Alvarez and Edna O'Shaughnessy is a revised version of the introduction to the ACP Study Day in February 2005 on ‘Integration, Unintegration, Disintegration’, at which Alvarez and O'Shaughnessy had presented and which the author had chaired. The background to the debate is given in terms of how the ACP Study Day itself came about, and the central theme is highlighted in terms of the question of whether unintegration is conceived of as a normal stage of development or only a temporary state of mind in response to catastrophic anxieties. Brief clinical material from a case supervised by the author is discussed in order to elaborate this central question.     

Strain‐specific aggressive behavior of male mice submitted to different husbandry procedures

Severe aggression within groups of male laboratory mice can cause serious welfare problems. Previous experiments have shown that the transfer of specific olfactory cues during cage cleaning and the provision of nesting material decrease aggression and stress in group‐housed male mice. In this study, the combined effect of these husbandry procedures was tested for their long‐term effect on aggression in two strains of male mice (BALB/c and CD‐1). We used postcleaning aggressive behavior, wound counts, and testosterone levels as indicators of aggressiveness. Physiological responses to social challenge were investigated through urinary corticosterone and adrenal tyrosine‐hydroxylase measurements. Furthermore, the aggression‐modulating effects of two enrichment items (ShepherdShack/DesRes and PVC tube) were explored. Marked differences were found between the two strains. CD‐1 mice were more aggressive, had higher testosterone levels but lower corticosterone levels, and had fewer wounds than BALB/c mice. However, in neither of the two strains was long‐term enrichment with nesting material and its transfer after cage cleaning effective in lasting reduction of intermale aggression. This may be explained by the fact that aggression levels were generally low. It seems that housing mice in small, socially stable groups or keeping social disturbances to a minimum considerably modulates aggression in group‐housed male mice. Mice of both strains housed in cages enriched with nesting material had lower urinary corticosterone levels than standard‐housed mice. We therefore conclude that the long‐term provision of nesting material, including the transfer of nesting material during cage cleaning, may enhance the welfare of laboratory mice. Aggr.

工作记忆表征精度加工需求对注意引导的影响

采用注意捕获范式, 通过行为和事件相关脑电位(ERP)实验, 探讨工作记忆表征精度加工需求对注意引导的影响, 行为结果发现, 在低精度加工需求条件下, 只有一个工作记忆表征引导注意, 且处于高激活状态的工作记忆表征产生的注意捕获大于低激活状态; 而在高精度加工需求条件下, 有两个工作记忆表征引导注意, 且处于高、低激活状态的工作记忆表征产生的注意捕获没有差异。ERP结果显示, 高精度加工需求条件下诱发的NSW和LPC大于低精度加工需求条件; 在高精度加工需求条件下, 干扰项与记忆项匹配比不匹配时, 诱发更大的N2和更小的N2pc, 而在低精度加工需求条件下, 干扰项与记忆项匹配和不匹配时诱发的N2、N2pc没有差异。研究表明, 工作记忆表征精度加工需求影响注意引导的机制可能是高精度加工需求下, 工作记忆表征消耗的认知资源增加, 搜索目标获得的资源减少, 干扰项捕获的注意增加。     

抑制引起的遗忘及其神经机制

当面对不愉快的提醒时, 人们通常会试图阻止那些不想要的记忆出现在脑海中。先前的研究表明, 抑制不想要的记忆的检索会降低这些记忆的可及性, 引起遗忘, 这一效应称为抑制引起的遗忘(suppression- induced forgetting, SIF)。SIF的神经机制涉及右背外侧前额叶皮层和额中回的激活增加, 以及海马的激活受到抑制。SIF的程度受记忆材料的情绪效价、个体的病理性情绪状态和训练的影响。未来研究应在深入了解SIF神经机制的基础上, 考虑如何提高临床病理性记忆的SIF效果, 以达到治疗目的。     

状态焦虑对回溯式时距判断的影响：认知评价和记忆偏向有调节的中介作用

探讨状态焦虑对回溯式时距判断的影响, 并检测记忆偏向与认知评价在其中的中介和调节作用。实验1招募大学生60人, 随机分为高、低状态焦虑组, 采用情绪诱导程序诱导高、低状态焦虑; 采用口头估计任务测量回溯式时距判断, 考察高、低状态焦虑诱导后的回溯式时距判断差异。实验2在实验1的基础上, 招募大学生60人, 增加自由回忆任务测量记忆偏向, 考察状态焦虑对回溯式时距判断的影响中记忆偏向的中介作用。实验3在实验1和实验2的基础上, 招募大学生90人, 增加视觉模拟心境量表测量认知评价, 考察状态焦虑对回溯式时距判断的影响, 并检测认知评价与记忆偏向在其中的作用。结果发现：(1)在回溯式时距判断中, 高状态焦虑比低状态焦虑更高估时距; (2)在状态焦虑对回溯式时距判断的影响中, 记忆偏向具有中介作用; (3)在状态焦虑对回溯式时距判断的影响中, 认知评价和记忆偏向存在有调节的中介作用：只有当认知评价得分较低时, 即对于认为焦虑对身体健康有害程度较低的个体而言, 在状态焦虑影响回溯式时距判断中, 记忆偏向具有完全中介作用, 即状态焦虑只通过记忆偏向影响回溯式时距判断。研究结果揭示了焦虑个体回溯式时距判断的内部过程, 验证了注意闸门模型中有关用于计时的记忆资源越多对于时距越高估的假设, 丰富了焦虑通过记忆偏向影响回溯式时距判断的解释视角, 为通过调整认知评价改善焦虑个体时距偏差提供了重要参考。     

Church discipline and excommunication

Abstract

A perspective of the Reformed conception of church discipline in the sixteenth century has highlighted two models: the disciplinarian one associated with Geneva and the magistratical one identified with Zurich. This essay argues that a simple binary distinction between the Geneva and Zurich models of church discipline is inadequate to account for the complexity and diversity of sixteenth-century Reformed theological positions, particularly as represented in the articulations of the influential reformer, Peter Martyr Vermigli.     

China and the Problem of Human Rights: Ancient Verities and Modern Realities

The six sections of the essay discuss recurrent issues relative to the modern advocacy of human rights and the vicissitudes of the Chinese response—universal standards versus cultural and historical particularity, individualism versus community, traditional Confucian ethics versus Western modernism, nativism versus foreign influence, the stability of the social order versus individual well-being, and the possibility of developing a view of rights a part of which is drawn from the Chinese philosophical tradition. The concluding segment examines historical conditions of law and religion and their relevance for contemporary discussion on human rights. By looking closely at selected classical texts and events, the essay offers both a sustained critique of Confucianism in its traditional formulation and a suggested attempt to re-interpret aspects of the tradition for the current situation.
