社会分类(分类)是群体认知和印象评价的依据, 交叉分类作为一种认知过程, 是指在知觉或评价他人时, 同时在两个或多个类别维度上进行社会分类, 形成在多个类别维度上内外群体身份的交叉。研究发现交叉分类既可以降低刻板印象, 也可以增强刻板印象。对此, 类别化视角的解释强调群体身份的作用, 而个体化视角的解释强调多重类别背景下去类别化的作用。现有的研究在如何理解并考察这一影响的不同方向上仍存在分歧, 同时, 也未能认识到刻板印象对于个体认知与认同的意义, 存在明显不足。今后的研究应重点探讨类别化视角的动机与认知过程, 个体化视角的优势类别与加工方式, 以及以自我归类为基础的整合。 相似文献

人工语法学习模型述评 总被引:2,自引:0,他引:2
述评了近年来影响较大的四个人工语法学习模型——THIYOS分类器系统、竞争组块模型、范例模型和联系者模型。它们都认为,人工语法学习所获得的知识中,一部分以规则、组块、总体类似性以及激活模式等形式到达意识层面,另一部分则残存在力量模式中,确定什么内容适合到达意识层面;后者即为内隐知识。这四种模型各抒己见,各有特点,并都为内隐学习的机理提供了重要依据。 相似文献

The authors present 2 experiments that establish the presence of knowledge partitioning in perceptual categorization. Many participants learned to rely on a context cue, which did not predict category membership but identified partial boundaries, to gate independent partial categorization strategies. When participants partitioned their knowledge, a strategy used in 1 context was unaffected by knowledge demonstrably present in other contexts. An exemplar model, attentional learning covering map, was shown to be unable to accommodate knowledge partitioning. Instead, a mixture-of-experts model, attention to rules and instances in a unified model (ATRIUM), could handle the results. The success of ATRIUM resulted from its assumption that people memorize not only exemplars but also the way in which they are to be classified. 相似文献

Do men seek more short-term mates than women? Buss and Schmitt (1993) showed a pattern of mean difference in the ideal number of sexual partners men and women desired over various time frames. We replicated these mean sex differences (e.g., ideal number over the next 30 years: Ms = 7.69 and 2.78 for men and women, respectively), but in both data sets the sampling distributions were highly skewed. In Study 1, we found few sex differences in medians across time frames (e.g., ideal number over the next 30 years: Mdn = 1 for both men and women). In Study 2, most college men (98.9%) and women (99.2%) said they wanted to settle down with one mutually exclusive sexual partner at some point in their life, ideally within the next 5 years. Neither medians in number of partners desired overall before settling down (replicating Study 1) nor medians in short-term partners desired before settling down (Mdn = 0) differed significantly by gender. Rather, men and women concurred: Short-term mating is not what humans typically seek. 相似文献

The purpose of this exploratory study was to examine variation in aspects of contemporary Korean fathering, such as warmth and involvement (frequency and task share), and its relationship to children's sex role development. One hundred and twenty-nine Korean families (fathers, mothers, and their 11- to 13-year-old children) completed standardized questionnaires addressing child-rearing practices, parental involvement, spousal support, and sex role orientations. Statistical analyses of the data revealed that warmth of fathering and father involvement (frequency and task share) were not significantly associated with children's sex role orientations. However, girls' femininity was significantly related to fathers' masculinity. 相似文献

Cognitive stimulation in brainstorming 总被引:1,自引:0,他引:1

Research on group brainstorming has demonstrated that it is less effective for generating large numbers of ideas than individual brainstorming, yet various scholars have presumed that group idea sharing should enhance cognitive stimulation and idea production. Three experiments examined the potential of cognitive stimulation in brainstorming. Experiments 1 and 2 used a paradigm in which individuals were exposed to ideas on audiotape as they were brainstorming, and Experiment 3 used the electronic brainstorming paradigm. Evidence was obtained for enhanced idea generation both during and after idea exposure. The attentional set of the participant and the content of the exposure manipulation (number of ideas, presence of irrelevant information) influenced this effect. These results are consistent with a cognitive perspective on group brainstorming. 相似文献

The mental model theory postulates that reasoners build models of the situations described in premises, and that these models normally represent only what is true. The theory has an unexpected consequence. It predicts the existence of illusions in inferences. Certain inferences should have compelling but erroneous conclusions. Two experiments corroborated the occurrence of such illusions in inferences about what is possible from disjunctions of quantified assertions, such as, "at least some of the plastic beads are not red." Experiment 1 showed that participants erroneously inferred that impossible situations were possible, and that possible situations were impossible, but that they performed well with control problems based on the same premises. Experiment 2 corroborated these findings in inferences from assertions based on dyadic relations, such as, "all the boys played with the girls." 相似文献

The present study examined the etiology of suicidal behavior from cognitive and developmental perspectives in a sample of 181 suicidal and nonsuicidal college students. We hypothesized that cognitive functioning would serve as a mediator between early life events and suicidal behavior. The present study examined child maltreatment, family instability, and poor general family environment as early negative life events, and examined self-esteem, locus of control, hopelessness, and problem-solving deficits as cognitive factors. In addition, individuals' perceived social support before age 18 and current social support and life stress were also examined in relation to the preceding variables. A series of structural equation analyses indicated that early negative life events have a mild impact on suicidal behavior, but a stronger impact on cognitive deficits, which in turn have a strong impact on suicidal behavior. 相似文献
