因果力比较范式下对效力PC理论的检验

在用图形方式集中呈现信息的条件下,用因果力大小比较的实验范式检验效力PC理论。233名大学生被试对不同化学药物影响动物基因变异的能力做大小比较判断。结果发现,对单一因果关系因果力大小的比较判断具有以下3个特点：（1）不对称性：在预防原因条件下的因果力判断一般符合效力PC理论,而在产生原因条件下的因果力判断一般不符合效力PC理论;（2）在同时变化协变值DP和结果基率P(E|~C)的产生原因条件下,多数被试使用DP规则。这与概率对比模型的预测相一致,而不支持效力PC理论;（3）在固定协变值DP而只变化结果基率P(E|~C)的产生原因条件下,多数被试使用变异比RP规则。这是目前所有的因果推理理论都不能解释的现象。     

Self-reported physical aggression among young men

This article describes two studies involving a questionnaire asking about the circumstances, antecedents, and consequences of the most recent fight among samples of young men (100 students in Study I; 88 students and 87 unemployed men in Study II). In Study I, the students alos completed a standard aggression questionnaire and one concerning masculine values to assess whether measures of physical aggressiveness were associated with traditional masculine role norms. There was a weak association with physical aggressiveness but not with reported fights. Students with traditionally masculine interests did report more fights. In Study II, both subsamples showed significant correlations between a masculine role subscale involving toughness from this study were primarily assessed in relation to hyphotheses derived from Darwinian sexual selection theory: that fights between young men are likely to arise from threats to personal integrity and status, women, and resoureces; that fights will be more related to social status and be more damageing among the unemployed men than the students. In line with these predictions, insults were a potent cause of fights in both samples, but public humiliation was a more common reason among the unemployed men, Money or property was more often a reason for fighting among the unemployed men also showed higher levels of anger and physical aggression (but not verbal aggression) on a standard aggression questionnaire. Other differences included the location of the fight, but there were no significant differences between the two samples in whether or not a fight had occured in the last 5 years. © 1995 Wiley-Liss, Inc.     

The action congruency effect on the feelings of agency

Previous studies suggest that the sense of agency (SoA), the feeling of control about one’s own actions and ensuing effects is also generated during action selection processes. We investigate whether the conflict at the action selection stage induced by a supraliminal stimulus, modulates an implicit measure of SoA, namely intentional binding. Furthermore, we were interested to investigate the influence of different types of stimulus-response compatibility on SoA. To this aim we compared the influence of an automatic imitation task and a stroop-like task on intentional binding. In both tasks participants performed congruent and incongruent fingers movements (key release) in response to an external stimulus. Their movements caused an effect and participants estimated the time between their action and the ensuing effect. We found a reduced intentional binding effect in incongruent compared to congruent conditions in both tasks. The results are discussed within the theoretical framework of the fluency of action.     

Set size,assertion form,thematic content and sampling in the selection task

Participants attempted to solve a modified version of Wason's (1966) selection task. Variables were: (1) sizes of the sets referenced by a specified assertion, (2) form of the assertion (conditional or categorical), (3) thematic content of the assertion (letters and numbers or makes and owners of taxicabs), and (4) the need for sampling or not. In Experiment 1, participants were given enough information to determine the truth or falsity of the specified assertion with certainty; in Experiment 2, they had to rely on sampling and could not determine the assertion's truth or falsity with certainty. Performance was better in Experiment 1 than in Experiment 2, but in both cases much better than what is typically obtained with the conventional selection task. The results support the hypothesis that performance of the selection task is sensitive to the sizes of the sets involved, add credence to the conclusion that framing the task in a thematically meaningful way can facilitate performance, and demonstrate that facilitation does not require deontic reasoning or a well-known convention being involved. The relationship between expressed confidence and level of performance is consistent with other studies showing the former to be a good predictor of the latter.     

Re-framing the characteristics of concepts and their relation to learning and cognition in artificial agents

In this work, the problems of knowledge acquisition and information processing are explored in relation to the definitions of concepts and conceptual processing, and their implications for artificial agents.The discussion focuses on views of cognition as a dynamic property in which the world is actively represented in grounded mental states which only have meaning in the action context. Reasoning is understood as an emerging property consequence of actions-environment couplings achieved through experience, and concepts as situated and dynamic phenomena enabling behaviours.Re-framing the characteristics of concepts is considered crucial to overcoming settled beliefs and reinterpreting new understandings in artificial systems.The first part presents a review of concepts from cognitive sciences. Support is found for views on grounded and embodied cognition, describing concepts as dynamic, flexible, context-dependent, and distributedly coded.That is argued to contrast with many technical implementations assuming concepts as categories, whilst explains limitations when grounding amodal symbols, or in unifying learning, perception and reasoning.The characteristics of concepts are linked to methods of active inference, self-organization, and deep learning to address challenges posed and to reinterpret emerging techniques.In a second part, an architecture based on deep generative models is presented to illustrate arguments elaborated. It is evaluated in a navigation task, showing that sufficient representations are created regarding situated behaviours with no semantics imposed on data. Moreover, adequate behaviours are achieved through a dynamic integration of perception and action in a single representational domain and process.     

求偶动机的心理效应

演化心理学认为人类的心理机能受到演化压力的塑造,性选择作为重要的演化动力因素,在人类心理机能的形成过程中扮演着重要角色。与性选择密切相连的求偶动机可以影响包括注意、知觉、记忆、决策及社会行为在内的一系列心理现象和行为,但求偶动机操控方法的混乱及研究过程中对文化和层级选择的忽视制约了这一领域工作的开展。进一步深化相关研究,以行为数据为基础,从神经、激素和基因层面建构立体的研究框架对于揭示背后机制有着重要作用。

The Effect of Intergroup Conflict on Ingroup Cooperation and Conformity: An Experimental Vignette Study

In this study, we aimed to test the hypothesis that intergroup conflict would enhance not only ingroup cooperation, but also conformity (frequency‐dependent tendency). One hundred and eighty undergraduate students participated in a vignette experiment. They read four scenarios describing daily intergroup conflict situations, and rated behavioral intention for ingroup cooperation and frequency‐dependent tendency of ingroup members. In each vignette, level of intergroup conflict (weak/moderate) was manipulated by costs of defeat. The results supported the hypothesis in part that intergroup conflict enhanced both ingroup cooperation and conformity.     

Personality Traits and Political Ideology: A First Global Assessment

This article presents the first assessment of how the five‐factor model of personality and political ideology are associated across the world. Personality traits become more and more important in the study of political behavior. And the relationship with ideology virtually parallels the history of this line of research. Yet, many existing studies are limited to single, highly developed countries and mostly draw on nonrandom or nonrepresentative samples. Our study, in contrasts, makes use of the most recent wave of the World Value Survey and analyzes the relationship comparatively in 21 countries from all continents. Results corroborate the most prominent findings about personality and ideology. However, effects of personality traits cannot be generalized easily across the world as effects vary considerably from country to country. Therefore, we additionally analyze specific preferences concerning social and economic policies on the one side. On the other, we theorize as well as model the moderating role of the country context by introducing cross‐level interaction effects.
