Despite being an effective predictor of job performance, empirically keyed biodata assessments have been criticized as black box empiricism unlikely to generalize to new contexts. This paper introduces a model that challenges this perspective, explicating how biodata content, job demands, and criterion variables collectively influence the construct validity, and generalizability of empirically scored biodata. Across two field studies, expected changes in scale correlations with external measures were found that coincided with changes in the contextual similarity between calibration and holdout contexts, the criteria used, and the content validity of biodata items. Collectively, this paper offers a framework that helps understand and optimize empirical biodata keying in practice, furthering confidence for their use in applied settings.  相似文献

Children younger than 3 years have difficulty with search tasks that involve hidden displacement. Partial visual information was provided about a ball's path as it moved toward a hiding place. Children (2.0 and 2.5 years old) saw a ball rolling down a ramp placed behind a transparent screen with 4 opaque doors. A wall, placed on the ramp and directly behind 1 of the doors, protruded above the screen and stopped the ball. Children were asked to find the ball. The transparency of the screen permitted visual tracking of the ball between the doors, but its final resting place was obscured. Both age groups were equally proficient at tracking the ball as it rolled behind the screen, but the 2.5-year-olds were more likely to reach to the correct door. Looking behavior was related to errors in the younger group in that tracking that stopped short or continued past the correct door was associated with incorrect choices.  相似文献

The absence or diminution of light is potentially an anxiety-arousing situation for, perhaps, all of us. Even a cursory look at the origin myths of many cultures reveals the chaotic, destructive, and dangerous aspects of darkness. Additionally, language reflects the same qualities metaphorically and symbolically. Developmentally, the arrival of the darkness of evening potentially signals object loss and ego regression. But factors other than ubiquitous references to a consideration of light and darkness are relevant. Can it be that we are all at least prone to depression due in part to this factor? Questions regarding possible biological causes of depression are perhaps unanswerable at this time. Is the seratonin level really associated with depression and light deprivation? Research is as yet inconclusive. If a relationship exists, another question must be asked: Will certain psychological situations affect a person's seratonin production? The answer to this question of how depression is associated with biological causes is certainly beyond the scope of this paper. Yet the preceding case history reveals at least some psychological causes of depression that were initially seen as biologically based. The SAD proponents would have treated Mr. B with light therapy. The quick solution of light therapy, based on a shaky theoretical base and lacking sturdy research, has too often replaced the psychoanalytic approach. In all too many situations psychoanalysts are being replaced by lightbulbs.  相似文献

Self-generated information is typically remembered better than perceived information (the generation effect). Experimental design produces an important limiting condition for this effect: Generation enhances recall in within-subjects designs, but typically not in between-subjects designs. However, Mulligan (2001) found that the generation effect emerged over repeated recall tests in a between-subjects design, calling into question the generality of this limiting condition. Two experiments further delineated the emergent generation effect Experiment 1 demonstrated that this effect does not require multiple discrete recall tests but may emerge on a single recall test of long duration. Experiment 2 demonstrated that the negative generation effect (a reversal of the typical generation effect produced under certain conditions) is abolished by multiple recall tests. In both experiments, the generate condition produced greater hypemnesia (increased recall over tests) than did the read condition.  相似文献

The frequency of theta activity may be important for hippocampal function. Anxiolytic drugs reduce theta frequency and have behavioral effects that are similar to those of hippocampal lesions. The effect of the anxiolytic benzodiazepine chlordiazepoxide (CDP) on theta frequency is partially mediated by the medial supramammillary nucleus (mSuM), part of an ascending theta-activating system. Rats were trained on the hippocampal-sensitive fixed-interval 60-sec schedule (FI60). CDP (5 mg/kg i.p.) released responding suppressed by nonreward, seen as increased leverpressing, and reduced theta frequency concurrently. Microinfusion of CDP (20 μg in 0.5 μl saline) into mSuM had as large effects on both frequency and behavior. Other nuclei mediate the benzodiazepine reduction of theta frequency in the open field and the water maze. But the mSuM appears to be the major, if not sole, nucleus controlling theta frequency and, so, hippocampal-mediated behavioral inhibition in the FI60 lever task.  相似文献

Cognitive models of social anxiety implicate various factors in the initiation and maintenance of socially anxious states, including anticipatory processing, self-focused attention and post-event processing. The present study focused on post-event processing, which is a post-mortem analysis following a social event that is described as ruminative in nature and serves to maintain social anxiety. Participants (N=112; 64 women, 48 men) were presented with vignettes that involved making mistakes in public and were instructed to record their thoughts to allow for the examination of the content of post-event processing. Ruminative coping and distraction were assessed via self-report. Results indicated that participants high in social anxiety (n=55) were more likely to ruminate and less likely to distract when faced with socially anxious stressors compared to those low in social anxiety (n=57). Further, as hypothesized, participants high in social anxiety recorded more negative thoughts and more upward counterfactual thoughts ('if only' type thoughts on how things could have been better; associated with negative affect) compared to those low in social anxiety. These results are discussed in terms of cognitive models of social anxiety.  相似文献
