This study explored the race-related self-regulation strategies of eight Indian South African university students (females: n = 4) attending a historically white university. Interactive qualitative analysis of their race-related experiences revealed that the students felt that they had been judged as being different, which resulted in overwhelming unwanted emotions, primarily anger and sadness. Moreover, the students reported the use a range of self-regulation strategies (such as introspection, engaging with trusted others, managing the situation, tolerating the experience of being judged, and making friends with people from other races) in a specific sequence to enhance their social acceptance on the campus. The findings suggest that adaptive self-regulation may enhance the social outcomes of historically disadvantaged, racial minority students. 相似文献

采用中学生、大学生焦虑敏感问卷和匹兹堡睡眠质量指数量表(PSQI),分别对1011名中学生和607名大学生进行调查。结果显示高焦虑敏感学生的PSQI总分显著高于低焦虑敏感学生,焦虑敏感及其三个因子与PSQI的相关都是中效应,焦虑敏感对青少年学生睡眠质量指数具有显著的正向预测作用,焦虑敏感水平越高,其睡眠质量越差。焦虑敏感可能以应激事件和健康问题作为致敏源,以焦虑等负性情绪作为敏感内容,在消极自动认知觉察与思维的介入下,进一步放大对有关负性情绪的感受与体验,从而影响青少年学生的睡眠质量。 相似文献

In this study, we used event-related brain potentials (ERPs) to examine the effects of aging on processes underlying task switching. The response time data revealed an age-related increase in mixing costs before controlling for general slowing and no effect of aging on switching costs. In the cue-locked epoch, the ERP data revealed little effect of age on the parietal P3 related to cue encoding, an age-related decrease in parietal activity related to cue retrieval, and an age-related increase in the amplitude of the parietal and frontal activity related to task set configuration and rule mapping. In the target-locked epoch, there was differential neural recruitment in younger and older adults in response to task mixing. These data are consistent with the idea that older adults may not fully implement task set before onset of the target stimulus. 相似文献

The own-race advantage in face recognition has been hypothesized as being due to a superiority in the processing of configural information for own-race faces. Here we examined the contributions of both configural and component processing to the own-race advantage. We recruited 48 Caucasian participants in Australia and 48 Chinese participants in Hong Kong, and had them study Caucasian and Chinese faces. After study, they were shown old faces (along with distractors) that were either blurred (isolating configural processing), in which high spatial frequencies were removed from the intact faces, or scrambled (isolating component processing), in which the locations of all face components were rearranged. Participants performed better on the memory test for own-race faces in both the blurred (configural) and scrambled (component) conditions, showing an own-race advantage for both configural and component processing. These results suggest that the own-race advantage in face recognition is due to a general facilitation in different forms of face processing. 相似文献

From an external perspective, cognitive agent behavior can be described by specifying (temporal) correlations of a certain complexity between stimuli (input states) and (re)actions (output states) of the agent. From an internal perspective the agent's dynamics can be characterized by direct (causal) temporal relations between internal and mental states of the agent. The latter type of specifications can be represented in a relatively simple, executable format, which enables different types of analysis of the agent's behavior. In particular, simulations of the agent's behavior under different (environmental) circumstances can be explored. Furthermore, by applying verification techniques, automated analysis of the consequences of the agent's behavior can be carried out. To enable such types of analysis when only given an external behavioral specification, this has to be transformed first into some type of executable format. An automated procedure for such a transformation is proposed in this paper. The application of the transformation procedure is demonstrated for a number of cases, showing examples of the types of analysis as mentioned for different forms of behavior. 相似文献

The current study was designed to investigate the timing and nature of interaction between the two languages of bilinguals. For this purpose, we compared discrimination of Canadian French and Canadian English coronal stops by simultaneous bilingual, monolingual and advanced early L2 learners of French and English. French /d/ is phonetically described as dental whereas English /d/ is described as alveolar. Using a categorial AXB task, the performance of all four groups was compared to chance and to the performance of native Hindi listeners. Hindi listeners performed well above chance in discriminating French and English /d/-initial syllables. The discrimination performance of advanced early L2 learners, but not simultaneous bilinguals, was consistent with one merged category for coronal stops in the two languages. The data provide evidence for interaction in L2 learners as well as simultaneous bilinguals; however, the nature of the interaction is different in the two groups. 相似文献

Journal editors are gatekeepers; they review and shape the work of others, and influence the journal's direction and quality. They also contribute to the body of knowledge within a field as authors. The author role of editors of the Journal of Applied Behavior Analysis is described. Annual publication rates of the 55 former and current editors and associate editors are presented and discussed. 相似文献

A least-squares algorithm for fitting ultrametric and path length or additive trees to two-way, two-mode proximity data is presented. The algorithm utilizes a penalty function to enforce the ultrametric inequality generalized for asymmetric, and generally rectangular (rather than square) proximity matrices in estimating an ultrametric tree. This stage is used in an alternating least-squares fashion with closed-form formulas for estimating path length constants for deriving path length trees. The algorithm is evaluated via two Monte Carlo studies. Examples of fitting ultrametric and path length trees are presented.G.

A computer program for Markov chain analysis is presented and discussed. The program is written in the language of the Statistical Analysis System (SAS) but detailed knowledge of SAS is not required for its use. The program tests hypotheses about the goodness of fit of first- and second-order Markov models. It also tests if transition probabilities are homogeneous between the first and the second half of each sequence.Presented, in part, at the Association for the Advancement of Behavior Therapy Convention, November 1984. 相似文献
