视觉表象扫描中的视角大小效应

采用视觉表象的几何距离扫描任务,通过两个实验首次揭示了视觉表象扫描中的视角大小效应。实验一采用3 (视角：2.7°,5.5°和8.2°) × 3 (扫描距离：0.0cm、0.4cm和0.8cm) 组内实验设计,探讨了视角大小这种表象前加工因素是否影响心理扫描的问题;实验二采用8 (视角：2.7°,4.1°,5.5°,6.9°,8.2°,9.6°,12.3°和17.1°) × 2 (扫描距离：0.4cm和0.8cm) 组内实验设计,探讨了视角大小如何影响心理扫描加工过程的问题。结果表明：（1）在视觉表象扫描中,扫描时间会受到表象对应刺激的视角大小影响,即使扫描的几何距离相等,不同视角大小条件下的扫描时间仍存在显著差异;（2）在4°到10°这个视角范围内心理扫描的时间显著短于这个范围之外的扫描时间,6.5°左右是视觉表象扫描的最佳视角。视角大小效应有别于心理扫描的大小效应和距离效应,为Kosslyn的表象计算理论增加了新的内容,具有重要的理论意义。同时它对仪表、图形设计以及棋牌游戏等工作和生活实践具有一定的应用价值     

Authors and publication practices

Although authors are usually considered to be the main perpetrators of research and publication misconduct, any person involved in the process has the potential to offend. Editors may breach ethical standards particularly with respect to conflicts of interest. In the same way that authors are now required to declare competing interests, notably commercial affiliations, financial interests and personal connections, so must editors. Editors can influence the chances of acceptance or rejection of a paper by reviewer selection. Reviewers should also be ready to disclose conflicts of interest. They must ensure that their reviews are evidence based and free from destructive criticism driven by self interest. It seems likely that ultimately we will progressively move towards 'open' peer review in which both the authors and the reviewers are known to each other. There is an urgent need for increased transparency of the relationship between editors and owners. The events of the last few years indicate that unless this interface is fully understood by all parties, conflicts may arise. There is also a need for a radical overhaul in the relationship between journals, journal editors and the biomedical industry. It is now increasingly accepted that all clinical trials should be registered in a centrally held database and that protocols should include the primary and secondary outcome measures and the intended approach to data analysis thereby avoiding opportunistic post hoc analyses. However, the even more radical proposal that journals should cease to publish clinical trials sponsored by industry deserves wider debate.     

作为情境变量的移情对暴力态度的影响

本研究将移情作为影响个体暴力态度的情境变量,通过对移情的启动来考察状态移情对暴力态度的影响。实验1在启动被试的移情感后,采用暴力IAT的方法考察被试内隐暴力态度的变化;实验2则在移情启动之后,用FMMU变态人格危险性评估问卷中的冲动倾向（VIO）考察被试的外显暴力的变化。实验结果显示,在启动被试的移情感后,我们没有发现被试的内隐和外显暴力态度发生显著变化,但经移情和性别的交互作用检验后发现,移情的启动减弱了男性被试的外显暴力态度,而对女性被试没有影响。研究结果表明,移情与暴力态度之间不存在内隐联结关系。根据以往的研究结果,移情对暴力态度的影响一是取决于意识层面的认知加工过程,二是与个体的特质性移情水平的高低有关。     

大学生过度消费量表编制

在文献分析和半结构化访谈的基础上编制大学生过度消费初始量表。以250名大学生为被试进行项目分析和探索性因素分析,以401名大学生为被试进行信效度检验,最终形成的正式量表包含透支、计划和享乐三个维度,共11个条目。结果发现,用于测量大学生过度消费的多维量表、各维单项目量表和单项目量表均具有较高的内部一致性信度以及良好的结构效度和效标效度,可以作为后续相关研究的测量工具。     

The internal family and the facts of life

Primitive defensive mechanisms innvolving splitting and projections are an essential process in the development of the infant. However, if these persist into adult life unmitigated by more depressive processes involving introjection and awareness of secure good objects they are shown to be inadequate to the task of coping with life crises, based as they are on the denial and distortion of reality. In this paper, I describe two patients who were seen in very different treatment settings and in whom such mechanisms were predominant. These began to fail when the patients were faced with difficult external events. These caused feelings of panic about impending mental disintegration. I then show how these patients sought to re-establish their primitive defensive structures.     

The effects of culture and friendship on rewarding honesty and punishing deception

The present research explores whether the type of relationship one holds with deceptive or honest actors influences cross-cultural differences in reward and punishment. Research suggests that Americans reward honest actors more than they punish deceptive perpetrators, whereas East Asians reward and punish equally (Wang & Leung, 2010). Our research suggests that the type of relationship with the actor matters for East Asians, but not for Americans. East Asians exhibit favoritism toward their friends by rewarding more than punishing them, but reward and punish equally when the actors are strangers (Experiment 1 and 2); Americans reward more than they punish regardless of the type of relationship (Experiment 2). Furthermore, the findings were replicated when the proposed mechanism – social mobility – was manipulated within the same culture (Experiment 3). We discuss the implications of these findings for understanding how friends versus strangers are rewarded and punished in an increasingly relationally complex world.     

Confrontation in the group analytic matrix: Toward a classification

This paper illustrates how confrontation is used in applying the Group Analytic model of Foulkes. Within the group, confrontation with images of the self and others provides a many-layered experience which transcends the classical psychoanalytic differentiation between confrontation, clarification and interpretation. A classification of seven types of confrontation is offered based on who confronts whom, and is linked with Foulkes's four levels of relationship within a group.Based on a paper read at the 9th Congress of the International Association of Group Psychotherapy, Zagreb, Yugoslavia, August 1986.     

HOW PSYCHIATRIC TREATMENTS CAN ENHANCE PSYCHOLOGICAL DEFENSE MECHANISMS

Psychological defense mechanisms are a powerful and often unappreciated force safeguarding mental health. Although rarely directed in this way, the most common forms of psychiatric treatment—psychotherapy and antidepressants—can enhance psychological defense mechanisms. Psychotherapy, through both specific and nonspecific factors, induces positive perspective shifts favoring positive cognitive distortions, including adaptive classical defense mechanisms and healthy attribution biases. Antidepressants, by altering very basic emotional information processing, such as facial expression recognition and emotional memories, also foster positive cognitive distortions. By shifting perceptions and thoughts in a positive direction, psychotherapy and antidepressants improve the capacity to dissociate from negative emotional stimuli.Brad Bowins, M.D., FRCP(C), is a staff psychiatrist at the University of Toronto Health Service and he is in private practice.
