Elderly persons (N=310) attending outpatient psychiatric clinics were given an interview on the 30-item Geriatric Depression Scale (T. L. Brink et al., 1982; J. A. Yesavage et al., 1983) and received an independent psychiatric evaluation. A 3-step binary logistic regression showed that 2 items measuring positive affect and 2 others measuring negative affect combined to produce diagnostic performance comparable with the full scale. This result was cross-validated on a different sample (N=134). A hierarchical measurement model in which the 4 items tapped 2 first-order factors (positive and negative affect), which in turn tapped a higher order construct of depression, provided excellent fit to the data.  相似文献

Racial and gender science achievement gaps in secondary education   总被引:1,自引:0,他引:1  
A substantial disparity exists for academic achievement in science between Black and White primary-school children. A similar gap exists between boys and girls. The extent to which secondary education influences these achievement gaps has not been established. The authors report analyses showing how these science achievement gaps change as a function of secondary education. Analyses of data from a large, nationally representative longitudinal study of academic achievement showed that racial disparities and disparities associated with gender continue to increase throughout high school.  相似文献

In this paper the author explores the theoretical and technical issues relating to taking notes of analytic sessions, using an introspective approach. The paper discusses the lack of a consistent approach to note taking amongst analysts and sets out to demonstrate that systematic note taking can be helpful to the analyst. The author describes his discovery that an initial phase where as much data was recorded as possible did not prove to be reliably helpful in clinical work and initially actively interfered with recall in subsequent sessions. The impact of the nature of the analytic session itself and the focus of the analyst's interest on recall is discussed. The author then describes how he modified his note taking technique to classify information from sessions into four categories which enabled the analyst to select which information to record in notes. The characteristics of memory and its constructive nature are discussed in relation to the problems that arise in making accurate notes of analytic sessions.  相似文献

Younger and older adults were compared on new tests for item and temporal memory suitable for use in future electrophysiological or neuroimaging studies. Following a series of 10 simple line drawings, 4-choice panels containing two previously seen targets and two novel distractors appeared. Participants identified which pictures had been seen previously (item), or which of the items was presented earliest (temporal order). Performance of younger adults was superior to that of older adults. Memory for item and temporal order were equivalent in the younger group. In contrast, the item memory of the older group was superior to memory for temporal order, confirming previous evidence of differential impairment of memory for temporal order with age.  相似文献

This study examined possible effects of aging on the lateralization of stimulus-evoked emotional facial muscle activity. Older participants (mean age 68.4 years) and younger participants (mean age 26.4 years) viewed slides of positive, neutral, or negative emotional content. While participants viewed the slides, bilateral electromyographic (EMG) recordings were obtained from the skin surface over zygomatic and corrugator facial muscles. The participants also made ratings of experienced emotional valence and arousal. Expected patterns of subjective experience and asymmetrical EMG activity were found in response to target stimuli. Greater corrugator muscle activity occurred during presentation of negative stimuli, whereas greater zygomatic muscle activity occurred during presentation of positive stimuli. Consistent with right-hemisphere specialization theories of emotion, left-sided facial EMG activity was consistently greater than that of the right side during presentation of emotional stimuli. However, neither subjective ratings nor EMG patterns showed a significant effect of age group. Such similar patterns of emotional response for the two groups suggest, that the aging process does not produce marked changes in stimulus-evoked emotional experience or in the pattern, magnitude, or lateralization of facial muscle activity associated with emotional states.  相似文献

Rodent studies demonstrate parallel age-related changes in spatial memory and the hippocampal formation. Converging cognitive, neuropsychological, and neurobiological evidence suggests similar changes in humans, although these correlates have not been studied in the same individuals. The purpose of the current project was to develop and validate a human analog of a rodent spatial memory task for future use in correlative studies of spatial memory and brain structure and function. Younger and older healthy adults studied the location of a target relative to distal cues in a large tent-like enclosure. Group performances were similar for the practice trial, which could be solved verbally, suggesting similar abilities to remember the configuration of multiple stimuli in a large space. However, on subsequent trials, which depended more upon spatial memory, older adults were impaired relative to their younger counterparts.  相似文献

I will argue that a desert-based justification for treating a person in a certain way is a justification that holds this treatment to be justified simply by what the person is like and what he or she has done, independent of (1) the fact that treating the person in this way will have good effects (or that treating people like him or her in this way will have such effects); (2) the fact that this treatment is called for by some (justified) institution or practice; or (3) the fact that the person could have avoided being subject to this treatment by choosing appropriately, and therefore cannot complain of it. I will explore the implications of this understanding of desert for the role of desert-based justifications of blame, punishment, and economic reward.  相似文献

This study investigated the relationships among leisure, social self image, peer pressure and at-risk behaviours of adolescents in Nigeria. It also examined the moderating roles of gender, age, and locale and school type on measured relationships. A total of 1,141 adolescents with a mean age of 16 participated in the study. The results revealed significant relationships among leisure, social self-image, peer pressure and involvement in at-risk behaviours. Leisure was found to be greatest predictor of at-risk behaviours. The variable of gender stood out as a significant moderator of the relationships between leisure, social self-image, peer pressure and at-risk behaviours, while school type moderated only the relationship between leisure and at-risk behaviours.  相似文献
