This paper examines the relationships between self‐identified crowd membership, attributional characteristics, and perceptions of parental style among students in their first year of high school (N = 893). The aim was to assess the extent to which group identity is reflected in self‐reported characteristics. Most students self‐identified either as studious, athletes, populars, rebels, or normals (N = 669) and also completed measures of perceptions of parental styles and attributional style. Consistent differences were observed between self‐identified studious and rebel teenagers. One‐way ANOVAS revealed significant group differences on mother's authoritativeness, father's authoritativeness, positive attributional style, and negative attributional style. These results are discussed with reference to the interplay between group influences and individual characteristics. Copyright © 2005 John Wiley & Sons, Ltd. 相似文献

The present study examined the effects of orthographic neighborhood (N) size on the cognitive processes underlying Chinese character reading. Previous research has shown increasing N size facilitates word naming and recognition performance in alphabetic languages. Experiment 1 revealed that a large N size was associated with a general inhibition of processes underlying character reading, in contrast to previous findings with alphabetic languages. This inhibitory effect was influenced by regularity and consistency. Experiment 2 sought to assess the effects of higher-frequency neighbors on character naming performance. The results revealed that higher-frequency neighbors with different pronunciation to the target interfered with the phonological retrieval of targets. We propose that this type of interference may have caused the N size effect observed in Experiment 1. The results of Experiment 3 revealed that a large N size facilitated target naming in the absence of higher-frequency neighbors. The current results shed light on the processes underlying character naming, and we propose possible cognitive mechanisms of the N size effect on Chinese character naming. 相似文献

The present study examines the influence of hierarchical level on category representation. Three computational models of representation – an exemplar model, a prototype model and an ideal representation model – were evaluated in their ability to account for the typicality gradient of categories at two hierarchical levels in the conceptual domain of clothes. The domain contains 20 subordinate categories (e.g., trousers, stockings and underwear) and an encompassing superordinate category (CLOTHES). The models were evaluated both in terms of their ability to fit the empirical data and their generalizability through marginal likelihood. The hierarchical level was found to clearly influence the type of representation: For concepts at the subordinate level, exemplar representations were supported. At the superordinate level, however, an ideal representation was overwhelmingly preferred over exemplar and prototype representations. This finding contributes to the increasingly dominant view that the human conceptual apparatus adopts both exemplar representations and more abstract representations, contradicting unitary approaches to categorization. 相似文献

多体素模式分析(multi-voxel pattern analysis,MVPA)是一种基于机器学习理论发展出来的新的功能磁共振数据分析技术。MVPA技术通过训练分类器,对由不同认知状态引起的多体素信号模式进行分类。与传统的基于单个体素的分析方法相比,该技术可更敏感地检测脑对认知状态的表征,并使得从神经信号解码认知状态成为可能。文章介绍MVPA技术的基本原理、分析步骤以及可以用MVPA来解决的科学问题,并对应用中可能面临的问题提供了参考建议。 相似文献

This research investigated whether people are biased against migrants partly because they find migrants more difficult to cognitively process than nonmigrants. In Study 1, 181 undergraduate students evaluated migrant and nonmigrant members of two minimal groups and reported the difficulty that they experienced in thinking about each type of target. Participants rated migrants less positively than nonmigrants, and difficulty ratings partially mediated this effect. Study 2 (N = 191) replicated these findings and demonstrated similar findings for individuals who had been excluded from minimal groups. This evidence implies that migrant bias can be explained partly in terms of the difficulty that people have in processing information about migrants, and that it is related to migrants’ exclusion from their original group. 相似文献

Aim: To explore therapists' perceptions of the relative benefits and pitfalls of group work and individual counselling for bereaved clients. Method: Semi-structured interviews with nine experienced bereavement therapists from a range of different contexts generated data which was analysed using grounded theory methodology. Findings: Groups were perceived as having a normalising influence, helping members make new social contacts and practice social skills. Individual counselling was seen as facilitating the initial telling of the story and the expression of extreme emotion. Discussion: The findings suggest that individual counselling may be useful as a primary intervention easing ‘emotional loneliness’ caused by the death of a spouse or attachment figure. Group work may be of more benefit later in the bereavement process, facilitating an engagement with the outside world and alleviating ‘social loneliness’. Implications for practice: This suggests that bereavement services might usefully combine group and individual provision. Initial assessment could help clients clarify their needs and facilitate their choice of service. This would be more cost effective and potentially ease clients' bereavement experience. 相似文献

There has been little research on the effects of the many procedural variables in applied group contingencies. In the present study, an individualized contingency and three group contingencies with different “responder” criteria (e.g., reward based on the group average, reward based on the work of a designated, low-achieving student, or reward based on the work of a randomly selected student) were applied to the academic work of primary grade children in a learning disabilities classroom. Group social interaction during each contingency was measured systematically. Although there were large individual differences in students' academic and social responses to the different contingencies, some consistent effects were observed. Two of the four low-achieving target students did their best academic work during the group contingency which focused on their performance as a designated responder. This type of contingency also produced high levels of positive social interaction in three of four groups of children observed. 相似文献

Participants were asked to recall the names when shown photographs of faces in both a semantic task (Experiment 1) and an episodic task (Experiments 2 and 3). When recall failed, feeling of knowing (FOK) ratings were solicited. In addition, participants reported on the strategies that they used to make their ratings, whether they could recall other pieces of information (the target-accessibility strategy, e.g., Koriat, A. (1993). How do we know that? The accessibility model of the feeling of knowing. Psychological Review, 100, 609–639) or whether the faces simply looked familiar (the cue-familiarity strategy, e.g., Schwartz, B. L., & Metcalfe, J. (1992). Cue familiarity but not target accessibility enhances feeling of knowing ratings. Journal of Experimental Psychology: Learning, Memory, and Cognition, 18, 1074–1083). In all experiments, FOK ratings were fairly accurate in that participants were successful in predicting their performance on a subsequent recognition test. More importantly, participants reported using the cue-familiarity strategy more often, although they gave higher FOK ratings when they reported using the target-accessibility strategy. The FOK ratings that were given using the two strategies were equally accurate. 相似文献
