Relational Frame Theory posits that complex language develops through arbitrarily applicable relational networks, with potential implications for individuals with autism. Responding relationally based on comparison occurs when participants respond to any number of comparative properties, such as “bigger” or “faster.” Experiment 1 established two 3-member comparative networks, in which a stimulus A was conditioned as “bigger” or “faster” than a stimulus B, and the stimulus B was conditioned as “bigger” or “faster” than a stimulus C in 2 children with autism. Both participants met the mastery criterion for the trained relations and demonstrated the emergence of the untrained combinatorially entailed A–C and C–A relations. The participants could also match the arbitrary A stimuli with larger or faster objects and the C stimuli with smaller or slower objects. The results were replicated in Experiment 2 with the same participants, where a 5-member relational network was established for the bigger/smaller relation. 相似文献

How, and how well, do people switch between exploration and exploitation to search for and accumulate resources? We study the decision processes underlying such exploration/exploitation trade-offs using a novel card selection task that captures the common situation of searching among multiple resources (e.g., jobs) that can be exploited without depleting. With experience, participants learn to switch appropriately between exploration and exploitation and approach optimal performance. We model participants' behavior on this task with random, threshold, and sampling strategies, and find that a linear decreasing threshold rule best fits participants' results. Further evidence that participants use decreasing threshold-based strategies comes from reaction time differences between exploration and exploitation; however, participants themselves report non-decreasing thresholds. Decreasing threshold strategies that “front-load” exploration and switch quickly to exploitation are particularly effective in resource accumulation tasks, in contrast to optimal stopping problems like the Secretary Problem requiring longer exploration. 相似文献

Differences in the perceived usefulness of five multiple-attribute decision support systems versus a basic spreadsheet are empirically assessed. Twenty-four college faculty members participated in a repeated measures experiment in which they used decision support software for personal computers to analyse semistructured multiple-attribute problems. The software packages employed were Criterium, Expert Choice, Logical Decision, VIMDA, VISA and the spreadsheet package Quattro Pro. A questionnaire was developed to assess user-friendliness of the software, confidence in the procedure implemented by the software, and users’ confidence in their results when employing the decision aids. Time to reach a decision was also measured. Significant differences were fund in the overall way users ranked these aids, in the perceived user-friendliness and the confidence in procedure among aids, and in the time it took to arrive at a result. Comments from users are also reported. © 1997 John Wiley & Sons, Ltd. 相似文献

The Universal Declaration of Human Rights is a general legislative framework for democratic societies. Studying the social representations of these basic human rights helps to explain how people understand and assess the basic rights and how these rights relate to everyday life. Over 400 Czech university students rated the 30 articles of the Declaration of Human Rights on various scales (degree of understanding, personal relevance, consequences for individual responsibility, for government, political parties, etc.). A semantic space was identified in which concepts (i.e. the Articles of the Declaration) could be located. A typology (clusters) of articles was then established within that semantic space. A factor analysis of the scales resulted in a two-dimensional solution (‘positive attitude’ and ‘personal influence’). Five clusters of assessed articles were identified within this semantic space.

异同判断加工中整体和局部特征的作用 总被引:1,自引:0,他引:1
采用三种整体局部特征(关系-属性,全局-局部,抽象-具体)图形,要求3组大学生被试完成异同判断任务,以考察异同判断加工中整体和局部特征的作用,探讨异同比较的加工机制。三个实验的结果表明:⑴三种整体特征均可加速同反应,因而不支持同判断加工是整体匹配的观点;⑵存在快同效应,但并不支持同判断的快速加工器对整个刺激加工完成后慢速比较器才开始工作的观点;⑶异反应时随差异特征的增多而减小,从而进一步支持异判断是分析加工、自终止的观点;⑷异反应时随差异特征从上至下、从整体到局部而增加,意味着异判断加工的顺序可能是自上而下、从整体到局部。上述结果支持研究假设:同判断的快速加工器先加工整体特征,然后再和异判断的慢速比较器一起开始加工局部特征。 相似文献

The effects of exposure to muscular male models among men: exploring the moderating role of gym use and exercise motivation 总被引:1,自引:1,他引:0
This study examines the effects of exposure to the muscular male body ideal on body-focused negative affect among male gym users and non-exercisers. As hypothesized, the impact of media exposure depended on men's exercise status. Non-exercisers (n = 58) reported greater body-focused negative affect after exposure to images of muscular male models than after neutral images (no model controls), whereas gym users (n = 58) showed a tendency for less body-focused negative affect after the model images than after the control images. Furthermore, the extent to which gym users were motivated to increase strength and muscularity moderated these exposure effects; men who reported stronger strength and muscularity exercise motivation reported a greater degree of self-enhancement after exposure to the muscular ideal. The findings are interpreted with respect to likely differences in motives for social comparisons. 相似文献

This article proposes the Thurstonian paired comparison model to assess vocational preferences and uses this approach to evaluate the Realistic, Investigative, Artistic, Social, Enterprise, and Conventional (RIASEC) model in the Basque Country (Spain). First, one unrestricted model is estimated in the Structural Equation Modelling framework using one paired comparison design. Secondly, the RIASEC circumplex structure is evaluated upon the estimated latent preferences correlation matrix. The results show good fit between the Thurstonian model and the data, but do not confirm the RIASEC structure in the Basque population. 相似文献

Gender differences in speed of perceptual comparison, of picture-plane mental rotation, and in switching costs between trials that do and do not require mental rotation, were investigated as a function of stimulus material with a total sample size of N=360. Alphanumeric characters, PMA symbols, animal drawings, polygons and 3D cube figures were used with an otherwise completely equivalent experimental design in which age and speed-based IQ were comparable across male and female groups. Small gender-related differences in speed of perceptual comparison were found with the magnitude as well as the direction depending upon the stimulus material. Polygons were the only material that produced substantial and reliable gender differences in mental rotation speed, and additionally revealed gender differences in switching costs. Thus, whereas gender differences in paper-pencil mental rotation tests constitute an empirical reality, the generalization that men outperform women in the speed of mental rotation was not supported in the present experiment. 相似文献

This paper examines the influence that social category diversity (i.e., working with an in-group or out-group member) has on individual levels of motivation. The results of two experiments provide evidence that individuals increase their effort more when being outperformed by an out-group instead of an in-group member (Experiment 1), but only when the potential for social comparison is present (Experiment 2). We discuss the implications of this research for understanding how and why social category diversity may impact individual levels of motivation. 相似文献

AbstractThe paper spells out implications of a perspective on religious individualisation that is both comparative and analytical and discusses the various issues that this line of research has to confront. Arguing against notions of modern Western exceptionalism, it points to the selectivity of Western forms of (religious) individualisation and makes a case for the inclusion of additional forms of articulating individual agency and ‘selfhood'. The paper takes individualisation as an inter-subjective, social phenomenon and connects it to the concept of social imaginaries. Opposing standard concepts of modernisation the paper nevertheless brings processuality centre stage, emphasising contingency. The paper discusses the possibility of the convergence of contextual developmental trends and the question of transculturality of notions of self and agency. With reference to the dimension of critique included in visions of religious individualisation, the paper finally points to the effects processes of religious individualisation can have on human actors within, and beyond, the realm of spirituality, including the recognition of subjectivities and the strengthening of actors’ resilience. 相似文献
