The purpose of the present study was to test whether or not a biodata instrument could be used to predict turnover, organizational commitment, and job performance in healthcare organizations. A criterion‐related, predictive validation strategy was used using a sample of 672 employees from two different hospitals in the southeastern United States. Supervisory ra0tings of organizational commitment and job performance were highly correlated with responses to the organizational commitment scale and the total score on the biodata instrument, respectively. Actual turnover was correlated with responses to the retention scale, although the effect size was small. Additionally, the study examined the fairness of biodata in this context as it relates to differences in performance among minority and non‐minority candidates. The findings in this study suggest that using such an instrument may provide organizations with the potential to improve organizational commitment and job performance, while reducing turnover with minimal group differences. 相似文献

Two experiments demonstrate that 14‐ to 18‐month‐old toddlers can adaptively change how they categorize a set of objects within a single session, and that this ability is related to vocabulary size. In both experiments, toddlers were presented with a sequential touching task with objects that could be categorized either according to some perceptually salient dimension corresponding to a taxonomic distinction (e.g. animals vs. vehicles) or to some less obvious dimension (e.g. rigid vs. deformable). In each experiment, children with larger productive vocabularies responded to both dimensions, showing evidence of sensitivity to each way of categorizing the items. Children with smaller productive vocabularies attended only to the taxonomically related categorical grouping. These experiments confirm that toddlers can adaptively shift the basis of their categorization and highlight the dynamic interaction between the child and the current task in early categorization. 相似文献

Younger and older adults were compared in three experiments, using procedures that had been shown to affect the spread of visual attention. The attentional effects found in previous experiments were replicated. A broader focus of attention speeded responses to peripheral targets. In addition, two established findings concerning aging were replicated: Responses were slower in older than in younger adults, and, in certain conditions, they slowed more rapidly as target eccentricity increased. No interactions of age effects with attentional manipulations were found. The results of all three experiments were consistent with the interpretation that younger and older adults do not differ in the allocation of attention. 相似文献

After a night of normal sleep, 36 subjects were divided into three groups of 12. One group was allowed to continue sleeping normally, one group had four hours continuous sleep and the third group had three 80-min periods of sleep distributed throughout the 24-h period, for the next four days. Subjects were given a visual vigilance test on each day. Overall performance was rather better following distributed than following continuous reduced sleep, but rather worse than following 8 h of sleep. The main difference between the reduced sleep groups was in their decision criterion. It was suggested that this difference mainly reflected the difference in time since the two groups had last slept. 相似文献
