This study attempted to apply the relative deprivation theory to preferential selection research. Two questions were addressed
in this context: First, does preferential selection cause feelings of injustice or deprivation? and, second, can the magnitude
of such feelings of injustice be predicted? A questionnaire was designed to assess fairness perceptions of all types of selection
outcomes: preferential selection; together with selection involving discrimination against minorities and selections without
either forms of discrimination. Results showed that preferential selection caused feelings of injustice. The level of felt
injustice associated with preferential selection was identical to that due to discrimination against minorities. Further,
the magnitude of felt injustice due to preferential selection could be predicted by the size of the discrepancy in “performance-relevant
merits” between the selected minority candidate and the unsuccessful majority candidate. The study also compared effects of
the “self-other” comparison process, used in previous relative deprivation research, and a “other-other” comparison process
on justice perception. Implications of the results for the application of relative deprivation theory to preferential selection
research were discussed. 相似文献

Measures of spatial cognition, neighborhood knowledge, and neighborhood use from the research described by Walsh, Krauss, and Regnier (1981) were examined to determine if laboratory tests of spatial cognition were significant predictors of older adults' use of their neighborhoods. The overall results show that laboratory-based measures of spatial cognition and subjects' knowledge of their neighborhoods are both significant predictors of their use of neighborhood goods and services. The ability to learn and remember the location and orientation of objects, when contextual cues were not provided at test, was more predictive of the participants' neighborhood use than either the participants' number of years in the neighborhood or their mobility. Spatial memory as measured by the Educational Testing Service Building Memory task predicted neighborhood knowledge, which was predictive of neighborhood use. 相似文献

Elders exposed to either progressive or imaginal relaxation procedures reported significant relaxation effects and showed improvement on measures of personal functioning. The results of the Physical Assessment Scale of the Relaxation Inventory indicated that relaxation responses were acquired within and across sessions. Large, consistent changes in relaxation occurred in all 4 sessions. The Symptom Checklist-90-R, which measures self-reported personal adjustment, showed significant positive changes following relaxation training and at 1-month follow-up. Elders who imagined muscle tension release profited as much as those engaged in actual muscle tension-release activities. This finding is of importance for older adults who may experience physical limitations that contraindicate muscle-tension-release procedures. 相似文献

Adult age differences were explored on 3 short tests of the ability to generate and manipulate mental images. Age-related decrements were found in all 3 tests and were especially marked on the Clock Test. The tests are all reliable, as shown by test-retest reliability coefficients. Correlations also revealed that the Brooks Letter Test and the East-West Test appear to tap one common underlying ability, whereas the Clock Test measured a somewhat different ability. The East-West and Clock tests, in particular, may provide rapid and easily administered assessments of age-related changes in aspects of mental imagery. 相似文献

Research into the victims of crime is of fairly recent origin and has been centred in America. However, a review of research
into the experience of the elderly as the victims of crime, and their anxiety about crime, reveals a paradox. Numerous studies
show that while the elderly are less likely to be the victims of crime than are the other age groups, they are among those
who exhibit most anxiety over crime. The research is discussed in the context of theories of why the elderly appear as a low-risk
group and in terms of an attempt to explain the paradox. 相似文献

Confirmatory factor analysis of Wallston's Multidimensional Health Locus of Control Scale and Krantz's Health Opinion Survey was conducted using 197 nondiabetic and 171 diabetic older adults. Qualified support was found for the 3-factor structure of the Wallston measure when applied to older adults. The Krantz model provided a less-than-adequate representation of the older sample's data. When the items from these 2 measures were combined, a 4-factor structure was found. Multisample simultaneous factor analyses using LISREL revealed that the factor structures of the Wallston and the Krantz measures fit the diabetic and the nondiabetic samples fairly equivalently. Despite the similarities in factor structures, diabetic individuals reported greater belief in powerful others and less desire for behavioral involvement in the health-care process than did nondiabetics. 相似文献

The present research examined whether line-ups based on target (‘suspect’) face similarity are biased or suggestive. Four experiments are described in which subjects constructed photographic line-ups by selecting foils similar in appearance to a target. Later, another group of subjects who had not seen the faces before (mock witnesses) were asked to pick out the targets from the line-ups. All four experiments showed that mock witnesses selected the target significantly more often than expected by chance, thereby demonstrating suggestiveness. Three alternative line-up construction methods were also evaluated. In these methods, foil selection was based not only on target similarity but also on similarity with one or more of the other line-up faces. Results showed that alternative line-up targets were not selected significantly more often than chance, suggesting that bias was reduced. An overall analysis showed that the alternative line-ups were significantly less suggestive than target-based line-ups. The results indicate that foil selection procedures that incorporate foil-to-foil similarity produce fairer line-ups than those exclusively based on target similarity. 相似文献
