作者用以大学生被试的一个实验考察归类不确定情景下样例的代表典型性对特征归纳预测的可能影响。实验结果表明,预测特征相对于目标特征的综合条件概率影响特征归纳预测,而样例的代表典型性并不影响特征归纳预测,没有出现样例的代表典型性效应。预测特征综合条件概率策略能预测解释这种结果。 相似文献

归类不确定情景下特征推理的综合条件概率模型 总被引:2,自引:1,他引:1
用大学生被试,通过三个实验探讨在集中呈现类别成员样本信息的归类不确定情景下的特征推理。实验结果表明,单纯的归类确定性程度和靶类别靶特征的代表性并不直接影响被试的特征推理,而是预测特征相对于目标特征的综合条件概率直接影响被试的特征推理;特征推理不是基于类别中介的间接推理,而是基于特征关联综合条件概率的直接推理。实验结果支持作者提出的预测特征综合条件概率模型。 相似文献

Analysts from a range of disciplines (especially sociology and social anthropology) highlight the role of the ‘other’ in the construction and definition of national identity. Recently some social psychologists have come to emphasize the inherently relational nature of identity. Drawing upon these recent investigations, the present paper reports a field study investigating the context‐dependent nature of group identity. Using a modified version of the Katz–Braly task, British subjects (n=240) stereotyped two national groups: Americans and British. They did so in two conditions. In the ‘one‐group’ conditions, subjects rated either of the two groups. In the ‘two‐group’ conditions, they rated one whilst also considering the other. Following Oakes, Haslam and Turner (1994) we predicted that whereas subjects' stereotypes of the national outgroup (the Americans) would be unaffected by this manipulation, their stereotype of the national ingroup (the British) would be affected. This prediction was confirmed. We also predicted that the national ingroup stereotype obtained in the ‘two‐group’ condition would be one which was defined in contrast to the American ‘other’ which constituted the comparative context. Using a measure which takes into account the applicability of ingroup‐defining terms to both the ingroup and the outgroup (the diagnosticity measure of stereotyping proposed by McCauley and Stitt, 1978) we show that the ingroup identity definition produced in this condition did indeed differentiate the British from the Americans. The significance of these data for those concerned with the application of social psychological theory to real‐life social problems is discussed. Copyright © 1999 John Wiley & Sons, Ltd. 相似文献

Comparing Exemplar- and Rule-Based Theories of Categorization 总被引:4,自引:0,他引:4
ABSTRACT— We address whether human categorization behavior is based on abstracted rules or stored exemplars. Although predictions of both theories often mimic each other in many designs, they can be differentiated. Experimental data reviewed does not support either theory exclusively. We find participants use rules when the stimuli are confusable and exemplars when they are distinct. By drawing on the distinction between simple stimuli (such as lines of various lengths) and complex ones (such as words and objects), we offer a dynamic view of category learning. Initially, categorization is based on rules. During learning, suitable features for discriminating stimuli may be gradually learned. Then, stimuli can be stored as exemplars and used to categorize novel stimuli without recourse to rules. 相似文献

The present research examines the extent to which the recognition of creative performance is structured by social group membership. It does this by analysing the award of merit prizes for Best Actor and Actress in a Leading Role for the international award of US‐based Oscars and British‐based BAFTAs since BAFTA's inception of this category in 1968. For both awards, the exclusive assessment criterion is the quality of artists’ performance in the international arena. Results show that US artists won a greater proportion of Oscars than BAFTAs (odds ratio: 2.10), whereas British artists won a greater proportion of BAFTAs than Oscars (OR: 2.26). Furthermore, results support the hypothesis that these patterns are more pronounced as the diagnostic value of a quality indicator increases – that is, in the conferring of actual awards rather than nominations. Specifically, US artists won a greater proportion of Oscar awards than nominations (OR: 1.77), while British artists won a greater proportion of BAFTA awards than nominations (OR: 1.62). Additional analyses show that the performances of in‐group actors in movies portraying in‐group culture (US culture in the case of Oscars, British culture in the case of BAFTAs) are more likely to be recognized than the performances of in‐group actors in movies portraying the culture of other (out‐)groups. These are the first data to provide clear evidence from the field that the recognition of exceptional creative performance is enhanced by shared social identity between perceivers and performers. 相似文献

汉语词汇产生中语义、语音层次之间的交互作用 总被引:7,自引:3,他引:7
采用3种方法考察汉语词汇产生中语义激活(词条选择)和音位编码这两个阶段之间的关系。实验一、二分别采用图片命名法和干扰字命名法,发现目标图片(“牛”)的语义相关词(“羊”)的语音信息得到了激活,说明汉语词汇产生中存在多重语音激活,音位编码在词条选择完成之前既已开始。实验三采用语义范畴判断法,考察语音信息的激活是否会向上反馈到词条和语义层次,发现目标图片(“羊”)的同音字(“阳”)不会促进对图片的语义判断。研究表明,多重语音激活与语音激活向词条和语义层次反馈是两个独立的,可以分割的问题。虽然实验一和二的结果符合相互作用理论,实验三的结果符合模块化观点,但就总体而言,本研究更加支持词汇产生中的模块化观点 相似文献

A fundamental question in vision research is whether visual recognition is determined by edge-based information (e.g., edge, line, and conjunction) or surface-based information (e.g., color, brightness, and texture). To investigate this question, we manipulated the stimulus onset asynchrony (SOA) between the scene and the mask in a backward masking task of natural scene categorization. The behavioral results showed that correct classification was higher for line-drawings than for color photographs when the SOA was 13 ms, but lower when the SOA was longer. The ERP results revealed that most latencies of early components were shorter for the line-drawings than for the color photographs, and the latencies gradually increased with the SOA for the color photographs but not for the line-drawings. The results provide new evidence that edge-based information is the primary determinant of natural scene categorization, receiving priority processing; by contrast, surface information takes longer to facilitate natural scene categorization. 相似文献

Pigeons are well known for their visual capabilities as well as their ability to categorize visual stimuli at both the basic and superordinate level. We adopt a reverse engineering approach to study categorization learning: Instead of training pigeons on predefined categories, we simply present stimuli and analyze neural output in search of categorical clustering on a solely neural level. We presented artificial stimuli, pictorial and grating stimuli, to pigeons without the need of any differential behavioral responding while recording from the nidopallium frontolaterale (NFL), a higher visual area in the avian brain. The pictorial stimuli differed in color and shape; the gratings differed in spatial frequency and amplitude. We computed representational dissimilarity matrices to reveal categorical clustering based on both neural data and pecking behavior. Based on neural output of the NFL, pictorial and grating stimuli were differentially represented in the brain. Pecking behavior showed a similar pattern, but to a lesser extent. A further subclustering within pictorial stimuli according to color and shape, and within gratings according to frequency and amplitude, was not present. Our study gives proof‐of‐concept that this reverse engineering approach—namely reading out categorical information from neural data—can be quite helpful in understanding the neural underpinnings of categorization learning. 相似文献

We examined the differences between majority and minority children (i.e., group membership) on racial categorization and perceived cultural distance, among 4‐ to 6‐year‐old children, in low diversified schools. We used a spontaneous social categorization task using pictures of children from three different racial groups broadly represented in France (Europeans, Black‐, and North‐Africans), and an evaluation of the perceived cultural distance between participants' in‐group and the racial group represented in the picture, adapted to children and based on three factors (language, eating habits, and music). Results revealed an effect of age on racial categorization: the older the children, the more successful they are in this task. They showed a significant effect of the racial group represented in the photos on perceived cultural distance: members of minority groups (i.e., Black‐ and North‐Africans) were evaluated as more different compared to those of the majority group on each of the factors. Finally, we got an interaction between participants' in‐group and the racial group represented in the pictures, for the language factor: members of the majority group perceived as more different photographs representing minorities peers than those representing majority peers, while participants belonging to minority groups perceived no differences between photographs, according to the racial criteria. 相似文献
