This study examined the fairness reactions to 10 personnel selection methods in a sample of Italian students. University students (N=137) were asked to rate the favorability of these selection procedures and then to evaluate them on eight procedural justice dimensions. Work‐sample tests were the most favorably rated of the selection methods, followed by résumés, written ability tests, interviews and personal references. Graphology was perceived negatively. Opportunity to perform and the perceived face validity of selection procedures were the strongest procedural justice dimensions for predicting the process favorability ratings. The results of this study are compared with those from similar studies conducted in other countries. Similar results have been found in the various countries where such research has been conducted to date.  相似文献

Cognitive neuropsychology provides a theoretical framework and methods that can be of value in the study of developmental disorders, but the "dissociation" logic at the centre of this approach is not well suited to the developmental context. This is illustrated with examples from specific language impairment. Within the developing language system there is ample evidence for interaction between levels of representation, with modularity emerging in the course of development. This means that one typically is seeking to explain a complex pattern of associated impairments, rather than highly selective deficits. For instance, a selective impairment in auditory processing can have repercussions through the language system and may lead to distinctive syntactic deficits that are seen in written as well as spoken language. Changes in the nature of representations and in the relationships between components of a developing system mean that cross-sectional data at a single point in development may be misleading indicators of the primary deficit. Furthermore, traditional cognitive neuropsychology places a disproportionate emphasis on representational (competence) deficits, with processing (performance) deficits being relatively neglected. Methods for distinguishing these two kinds of impairment are discussed, as well as other approaches for elucidating the underlying nature of developmental disorders.  相似文献

Brain mapping studies using dynamic imaging methods demonstrate areas regional cerebral blood flow (rCBF) decreases, as well as areas where increases, during performance of various experimental tasks. Task holds for both sets of cerebral blood flow changes (CBF), providing the opportunity to investigate areas that become and “activated” in the experimental condition relative to control state. Such data yield the intriguing observation that in areas in emotional processing, such as the amygdala, the posteromedial cortex, and the ventral anterior cingulate cortex, although flow as expected during specific emotion-related tasks, flow decreases performance of some attentionally demanding, cognitive tasks. Conversely, in some of the areas that appear to subserve cognitive functions, as the dorsal anterior cingulate and the dorsolateral prefrontal cortices, increases while performing attentionally demanding cognitive tasks, but during some experimentally induced and pathological emotional Although the specific nature of such reciprocal patterns of regional remains unclear, they may reflect an important cross-modal interaction during mental operations. The possibility that neural activity is less in areas required in emotional processing during some higher cognitive processes holds implications for the mechanisms underlying interactions cognition and emotion. Furthermore, the possibility that neural in some cognitive-processing areas is suppressed during intense states suggests mechanisms by which extreme fear or severe may interfere with cognitive performance.  相似文献

Since 1970 about 80% of the research on oral communication apprehension has used one of two versions of McCroskey's Personal Report of Communication Apprehension. The original 20-item PRCA was introduced for the purpose of measuring apprehension beyond the traditional public speaking context. Although the PRCA-20 is reliable, some serious criticism of it has centered on its ability to tap interpersonal behavior outcomes. In an attempt to bolster its interpersonal applicability, five “interpersonally-oriented” items were added to form the PRCA-25. The studies reported herein demonstrate that both versions fail to possess sufficient reliable variance to be applicable to contexts other than public settings. In addition, it was found that the interpersonal items are a separate component of the PRCA, and as such, do not justify being treated equal in terms of additivity and, therefore, reduce the construct integrity of the PRCA.  相似文献
