Situational judgment tests (SJTs) have become popular selection methods, with 59 empirical studies having been published since 1990. In contrast to prior narrative reviews or meta-analyses, this study develops (a) a comprehensive structure of SJT features, or “attributes,” (b) uses this structure to quantitatively and qualitatively summarize existing research in a content analysis, and then (c) uses the content analysis to generate directions for future research. The review is organized around a single question: What are the current practices in SJT research? Using this question as a foundation, we focus the content analysis on three significant theoretical and practical themes: (a) SJT development, scoring methods, and uses; (2) types of reliability estimates reported for SJTs, and (3) attributes that enhance or reduce internal consistency reliability. 相似文献

Pain typically signals damage to the body, and as such can be perceived as threatening and can elicit a strong emotional response. This ecological significance undoubtedly underlies pain’s well-known ability to demand attention. However, the neural mechanisms underlying this ability are poorly understood. Previous work from the author’s laboratory has reported behavioral evidence suggesting that participants disengage their attention from an incorrectly cued visual target stimulus and reorient it toward a somatic target more rapidly when the somatic target is painful than when it is nonpainful. Furthermore, electrophysiological data suggest that this effect is mediated by a stimulus-driven process, in which somatic threat detectors located in the dorsal posterior insula activate the medial and lateral prefrontal cortex areas involved in reorienting attention toward the painful target. In these previous studies, the painful and nonpainful somatic targets were given in separate experiments involving different participants. Here, the nonpainful and painful somatic targets were presented in random order within the same block of trials. Unlike in the previous studies, both the nonpainful and painful somatic targets activated the somatic threat detectors, and the times taken to disengage and reorient attention were the same for both. These electrophysiological and behavioral data suggest that somatic threat detectors can become sensitized to nonpainful somatic stimuli that are presented in a context that includes painful stimuli. 相似文献

Research focused on the prodromal period prior to the onset of psychosis is essential for the further development of strategies for early detection, early intervention, and disease pre-emption. Such efforts necessarily require the enrollment of individuals who are at risk of psychosis but have not yet developed a psychotic illness into research and treatment protocols. This work is becoming increasingly internationalized, which warrants special consideration of cultural differences in conceptualization of mental illness and international differences in health care practices and rights regarding research participation. The process of identifying and requesting informed consent from individuals at elevated risk for psychosis requires thoughtful communication about illness risk and often involves the participation of family members. Empirical studies of risk reasoning and decisional capacity in young people and individuals with psychosis suggest that most individuals who are at-risk for psychosis can adequately provide informed consent; however ongoing improvements to tools and procedures are important to ensure that this work proceeds with maximal consideration of relevant ethical issues. This review provides a discussion of these issues in the context of international research efforts. 相似文献

This study examined the relationship between depressive symptoms and bias in the prediction of future life events. Responding to internet announcements, 153 participants varying widely in self-reported depression symptom severity estimated the probability of 40 events occurring over the succeeding 30 days. After the 30-day period, participants reported which events occurred. Optimistic/pessimistic biases were related to level of depressive symptoms. A non-significant optimistic bias characterized participants with low depressive symptoms whereas a significant pessimistic bias characterized participants with high depressive symptoms. Those reporting mild symptoms did not exhibit a systematic pessimistic or optimistic bias. General imprecision in predictions for undesirable events was associated with depressive symptoms. These findings suggest that depression is associated with pessimistic bias rather than accuracy in judgment. 相似文献

Social dominance theory (SDT) suggests that prejudice legitimizes and maintains the existing social hierarchy. Consistent with an SDT explanation, it was predicted that (a) perceptions of threat to the existing social hierarchy and (b) social dominance orientation (SDO) would be related to stronger beliefs in stereotypes and "legitimizing myths." In addition, this analysis tests SDT's predicted interaction between perceptions of threat and SDO. It was predicted that for high SDO individuals the relation between perceptions of intergroup threat and the endorsement of legitimizing myths would be stronger than for low SDO individuals. These predictions were examined using a national probability General Social Survey archival data set. The results were consistent with our predictions and suggest that social dominance theory compliments and augments other threat theories of prejudice. 相似文献
