We argue that attachment theory may provide a useful framework for understanding individuals' reactions to social exclusion. Attachment theory suggests that social exclusion should prompt an individual to seek comfort from an accepting attachment figure. However, most experimental studies constrain individuals from seeking out an attachment figure to quell their distress, and may interfere with the process of recruiting internalized attachment figures. When the goal of recruiting attachment figure support is blocked, individuals may adopt deactivating strategies, such as emotional numbing, to reduce their distress. Alternatively, individuals may adopt hyperactivating strategies, such as ingratiating behaviors, to seek proximity to attachment figure substitutes. We conclude with recommendations for future avenues of exclusion research stemming from attachment theory. 相似文献

An important question is the extent to which declines in memory over time are due to passive loss or active interference from other stimuli. The purpose of the present study was to determine the extent to which implicit memory effects in the perceptual organization of sound sequences are subject to loss and interference. Toward this aim, we took advantage of two recently discovered context effects in the perceptual judgments of sound patterns, one that depends on stimulus features of previous sounds and one that depends on the previous perceptual organization of these sounds. The experiments measured how listeners’ perceptual organization of a tone sequence (test) was influenced by the frequency separation, or the perceptual organization, of the two preceding sequences (context1 and context2). The results demonstrated clear evidence for loss of context effects over time but little evidence for interference. However, they also revealed that context effects can be surprisingly persistent. The robust effects of loss, followed by persistence, were similar for the two types of context effects. We discuss whether the same auditory memories might contain information about basic stimulus features of sounds (i.e., frequency separation), as well as the perceptual organization of these sounds. 相似文献

A two-trial memory task, based on a free-choice exploration paradigm in a Y-maze, was previously developed to study recognition processes in Sprague-Dawley rats. Because this paradigm avoids the use of electric shock or deprivation that may have nonspecific effects and does not require learning of a rule, it may be particularly useful for studying memory in mice. Four inbred strains (Balb/cByJ, DBA/2J, C57BL/6J, and SJL/J), an F1 hybrid (C57BL/6 x SJL/J), and one outbred strain (CD1) were used to validate this task in mice and to characterize a strain distribution in response to novelty and working memory. Exploration was measured with a short (2 min) intertrial interval (ITI) between acquisition and retrieval, while memory was examined with longer intervals (30 min, 1 h, and 2 h). A study of the time course of the response to novelty revealed varying degrees of preference and/or habituation to novelty among the different strains, with CD1 exhibiting a very high response to novelty and others showing lower (C57 x SJL hybrids) to complete absence (SJL) of exploration of novelty. Memory span, assessed with increasing ITIs, varied widely among strains from 30 min (C57 x SJL hybrids) to at least 2 h (C57 and BALB). Such demonstrated sensitivity to a wide range of behavioral phenotypes supports the use of this spatial memory task as an effective tool for the study of genetic influences on the response to novelty and recognition processes in mice. 相似文献

Measurement of newcomer socialization: Construct validation of a multidimensional scale 总被引:1,自引:0,他引:1
A construct validation approach was taken to develop a primary measure of newcomer socialization that addresses shortcomings with a prior scale (Chao, Kelly, Wolf, Klein, & Gardner, 1994). Three separate groups of subject matter experts reviewed items to ensure the content validity of the Newcomer Socialization Questionnaire (NSQ). Studies 1 and 2 examined the NSQ’s psychometric properties using employed students and organizational newcomers as participants, respectively. Results illustrate scale reliability, factor structure, convergent and discriminant validity, and correlations with criterion variables. The NSQ measures three dimensions or domains of newcomer socialization: the organization, the group and the job/task. In addition, both factual knowledge and knowledge of expected role behaviors are assessed within each domain. Thus, the NSQ provides a useful measurement tool for researchers and practitioners interested in examining direct outcomes of being socialized. 相似文献

More than nine million Muslims currently live in Western Europe, which makes them the largest religious minority in the region. There has been significant political controversy in various European states over how best to recognize Muslims' religious rights. These questions have become even more significant and contentious in the aftermath of the September 11 attacks by Islamic extremists. Using privately commissioned polls on attitudes toward Muslim religious rights taken before and after September 11 in Britain, France, and Germany, this article determines the extent of popular opposition to state accommodation of Muslim practices and tests several leading theories of attitudes toward Muslims. We conclude that the most important determinants of attitudes toward Muslims are education and religious practice. 相似文献
