Visual perspective taking impairment in children with autistic spectrum disorder

Evidence from typical development and neuroimaging studies suggests that level 2 visual perspective taking - the knowledge that different people may see the same thing differently at the same time - is a mentalising task. Thus, we would expect children with autism, who fail typical mentalising tasks like false belief, to perform poorly on level 2 visual perspective taking as well. However, prior data on this issue are inconclusive. We re-examined this question, testing a group of 23 young autistic children, aged around 8 years with a verbal mental age of around 4 years and three groups of typical children (n = 60) ranging in age from 4 to 8 years on a level 2 visual perspective task and a closely matched mental rotation task. The results demonstrate that autistic children have difficulty with visual perspective taking compared to a task requiring mental rotation, relative to typical children. Furthermore, performance on the level 2 visual perspective taking task correlated with theory of mind performance. These findings resolve discrepancies in previous studies of visual perspective taking in autism, and demonstrate that level 2 visual perspective taking is a mentalising task.     

Preschool personality antecedents of narcissism in adolescence and young adulthood: A 20-year longitudinal study

This prospective study examined relations between preschool personality attributes and narcissism during adolescence and emerging adulthood. We created five a priori preschool scales anticipated to foretell future narcissism. Independent assessors evaluated the participants’ personality at ages 14, 18, and 23. Based upon these evaluations, we generated observer-based narcissism scales for each of these three ages. All preschool scales predicted subsequent narcissism, except Interpersonal Antagonism at age 23. According to mean scale and item scores analyses, narcissism increased significantly from age 14 to 18, followed by a slight but non-significant decline from age 18 to 23. The discussion focused on a developmental view of narcissism, the need for research on automatic processing and psychological defenses, and links between narcissism and attachment.     

4岁儿童对他人记忆的评判与错误信念理解的关系

从观点采择的角度考察儿童对他人记忆的评判及其与错误信念理解的关系。与他人分享记忆时,个体需要同时处理自我与他人对过去的表征和看法;而要顺利完成错误信念任务,个体需要同时加工自我的真实信念与他人的错误信念。因此个体对他人记忆的评判能力可能会与其对错误信念的理解相关。40名4岁儿童完成一系列错误信念任务和评判他人记忆是否正确任务,情境包括视觉、意图解释和情绪解释。结果表明,控制年龄、语言和记忆能力等因素后,被试评判他人记忆的成绩仍然可以预测其对错误信念的理解。这些结果为幼儿在回忆叙述中谈及他人越多,其心理理论越好提供了进一步的证据和可能的解释     

The Ethical Perspective: An Identity Theory of the Psychological Influences on Moral Choice

The 2008 Presidential Address presents the theory of ethical perspective, an identity theory of moral psychology designed to detect the psychological influences on moral choice. Part 1 treats findings on altruism and genocide as an analytical lens through which we can gain insight into political and moral behavior. Part 2 describes moral psychology as a field, presenting a new and broader conceptualization for the discipline. Part 3 outlines an identity theory of moral choice that focuses on the critical role of the ethical perspective, to suggest how an empirically based theory of moral choice looks in practice. Part 4 concentrates on the basic assumptions underlying the theory of ethical perspective. It presents empirical evidence that supports this theoretical framework, from fields as diverse as neuroscience and primatology to child development and linguistics, thus demonstrating political psychology's important links to other disciplines. In addition to presenting a new theory of moral psychology, designed to fill an important gap in the literature on ethics and moral choice, the Address treats studies of altruism and genocide as an illustration of research that reveals broader insight into the nature of political psychology as a discipline.     

When values matter: Expressing values in behavioral intentions for the near vs. distant future

It was predicted that because of their abstract nature, values will have greater impact on how individuals plan their distant future than their near future. Experiments 1 and 2 found that values better predict behavioral intentions for distant future situations than near future situations. Experiment 3 found that whereas high-level values predict behavioral intentions for more distant future situations, low-level feasibility considerations predict behavioral intentions for more proximate situation. Finally, Experiment 4 found that the temporal changes in the relationship between values and behavioral intentions depended on how the behavior was construed. Higher correspondence is found when behaviors are construed on a higher level and when behavior is planned for the more distant future than when the same behavior is construed on a lower level or is planned for the more proximal future. The implications of these findings for self-consistency and value conflicts are discussed.     

Better in the (near) future: Group-based differences in forecasting biases

Social identities are an important component of an individual’s self-concept. In the current research, we examine how identification with a group can lead to biased intergroup judgments similar to those made when evaluating the self, relative to others. We compared evaluations of in- and outgroups in order to examine differences in temporal perspective and optimistic evaluations. Our findings suggest that compared to an outgroup, ingroup members more strongly consider the future potential of their group, are more optimistic when considering future ingroup outcomes, and hold a more uniformly positive view of an ingroup’s future. Furthermore, we find that when evaluating ingroups, shifts in temporal perspectives are related to greater optimism. We conclude by discussing theoretical implications and future research related to temporal judgments and social groups.     

Eliciting intelligence from sources informed about counter‐interrogation strategies: An experimental study on the Scharff technique

The Scharff technique aims to elicit information by affecting the source's perception of the interviewer's existing knowledge. Although the technique has been found to be effective for gathering new information, countermeasures to the technique have not been examined. In a 2 × 2 between‐subjects experiment, we informed half of the 120 sources about the counter‐interrogation strategy of carefully considering the interviewer's prior knowledge and the tactic of providing information perceived as already known to the interviewer. After this, sources were interviewed with the Scharff technique or the Direct approach, widely used in human intelligence‐gathering situations and consisting of open‐ended and direct questions. We found that “informed sources” did not succeed in revealing information already known to the interviewer, where informed sources and uninformed sources revealed known information to a similar degree (1.62 pieces vs. 1.65 pieces). Sources interviewed with the Direct approach (vs. Scharff technique) revealed a larger amount of information previously known to the interviewer (2.18 pieces vs. 1.08 pieces). When interviewed with the Scharff technique, sources informed about the counter‐interrogation strategy attempted to adopt more counter‐interrogation strategies. The present study replicates earlier research on the Scharff technique as a technique effective in affecting the source's perception of the interviewer's prior knowledge. The results of the current study indicate that both the Scharff technique and the Direct approach might be similarly robust against counter‐interrogation strategies, in terms of gathering new information. Future studies should focus on implementing more comprehensive training in counter‐interrogation strategies for the sources.     

触觉二维图像识别中2D-3D空间信息转换的认知机制

可触摸的触觉二维图像是视觉障碍人群获取图像信息的重要方式。目前大多数触觉二维图像都是直接由视觉二维图像转化为的可触摸线条图。在视觉二维图像中,通常运用透视和视角等视觉原理将三维空间关系转换为二维平面关系。视觉系统经过长期大量知觉学习,习得了这种二维到三维的映射关系。但是触觉识别二维图像时,触觉系统如何建立二维平面与三维空间的映射,目前尚有待进一步的研究。影响触觉识别二维图像中二维-三维空间信息转换的视觉因素主要有透视、视角、遮挡、纹理梯度和镂空,直接将视觉二维图像转化为的触觉二维图像时,图像中包含的上述视觉因素通常会干扰触觉识别。结合已有研究,试图提出“双表象加工模型”来解释触摸二维图像时二维到三维空间信息转换的认知机制。该模型认为触觉识别二维图像依赖于两个表象系统的整合,即物体表象系统(涉及物体的大小、形状和纹理)与空间表象系统(涉及物体的空间关系、透视和视角)。两种表象系统的信息最终进行整合,在物体表象和空间表象成功匹配的基础上建立二维图像与三维空间之间的映射,通达长时记忆中的三维物体表征。双表象加工模型将有助于我们深入认识触知觉的认知机制,也将为触觉二维图像的设计提供理论依据。     

The evolution of cognition—a hypothesis

Behavior may be controlled by reactive systems. In a reactive system the motor output is exclusively driven by actual sensory input. An alternative solution to control behavior is given by “cognitive” systems capable of planning ahead. To this end the system has to be equipped with some kind of internal world model. A sensible basis of an internal world model might be a model of the system's own body. I show that a reactive system with the ability to control a body of complex geometry requires only a slight reorganization to form a cognitive system. This implies that the assumption that the evolution of cognitive properties requires the introduction of new, additional modules, namely internal world models, is not justified. Rather, these modules may already have existed before the system obtained cognitive properties. Furthermore, I discuss whether the occurrence of such world models may lead to systems having internal perspective.
