We examined the relationship between type 2 diabetes mellitus and cognitive function in a population-based sample of very old people. The sample comprised 338 persons, aged 80-93 years (mean age 83.5 years), of whom 70 persons had type 2 diabetes mellitus. Measures of cognitive functioning included tests of perceptual speed, visuo-spatial ability, inductive reasoning, short-term memory, semantic memory, episodic memory, and the Mini-Mental State Examination. Regression analyses showed that type 2 diabetes mellitus duration was related to test performance across all cognitive domains, with the exception of short-term memory, such that longer duration was associated with lower test performance. When cases with dementia were excluded from the sample, further analyses showed that diabetes duration was not associated with cognitive test performance. This indicates that diabetes is not related to lower cognitive function in the general population of non-demented old people. Diabetes, however, increases the risk for cerebrovascular incidents, like stroke, that may contribute to vascular dementia. 相似文献

This experiment sought further support for the view that early stage Alzheimer's disease (AD) disrupts cognitive structures that cast experience into a temporal framework. Forty participants, evenly divided between normal elderly (NE) and persons diagnosed with mild AD, viewed 19 lists of 14 pictures each. Following the presentation of each list participants were asked to identify the most recently experienced picture (target) from 3 pictures. A second stimulus was a picture never previously seen; the third picture was a distracting item that had appeared in the list on either one or three occasions. The results show that whereas choice accuracy of the NE group remained largely unimpaired regardless of the delay between the target and the judgment task or the frequency of the distractor, the AD participants exhibited large and profound deficits in temporal judgments, especially when distractor frequency was greater than the more recent event. In effect, the AD group relied on how often an event occurred rather than the time of its occurrence. This finding is consistent with previous research that found AD patients deficient in forming a temporal representation of their experience. 相似文献

Our aim in this paper is to bring attention to the applied value of collaborative memory research in aging. At this time, much collaborative memory research focuses on the negative effects of collaboration in younger adults, and is primarily basic in nature. Here, we highlight the positive effects of collaboration that have received less attention, with a particular emphasis on the applied value of these effects in older adults. We first review studies to show that recalling in a group improves later individual recall and reduces memory errors in older adults. We then outline a four-step approach towards bridging laboratory and applied collaborative memory research, which involves: (1) complementing traditional paradigms with more ecologically valid paradigms, (2) evaluating these paradigms in applied settings, (3) adapting these paradigms for use with cognitively intact and cognitively impaired populations, and (4) modifying these paradigms to examine the neural systems that operate during collaborative recall. 相似文献

Development as a dynamic system 总被引:1,自引:0,他引:1
Development is about creating something more from something less, for example, a walking and talking toddler from a helpless infant. One current theoretical framework views the developmental process as a change within a complex dynamic system. Development is seen as the emergent product of many decentralized and local interactions that occur in real time. We examine how studying the multicausality of real-time processes could be the key to understanding change over developmental time. We specifically consider recent research and theory on perseverative reaching by infants as a case study that demonstrates this approach. 相似文献

Toward Better Prevention: Constructions of Trust in the Sexual Relationships of Young Women 总被引:1,自引:0,他引:1
Research on HIV/AIDS interventions indicates that many heterosexual women implement the construct of trust when deciding if preventive measures are necessary. The personal construct model evaluated in this experiment proposes that young women's choice to resist changing from a trust to a nontrust position can be understood in terms of the relationship between their constructs and the hierarchical organization of their construct subsystems. Findings suggest that women with well-defined networks of implications on their nonpreferred pole of the trust/mistrust construct resist HIV-preventive messages that require them to mistrust their partner because the proposed change will involve successive use of subordinate constructs that are incompatible with each other. 相似文献

This article is concerned with the devaluation of the work of public intellectuals within the academic community. The principal reason given for this devaluation is that the work of the public intellectual does not have intellectual integrity as independent thought and original scholarship. I develop three models of public intellectual work: the permanent–critic model, the popularizer model, and the public–theorist model. I then consider each model in relation to the concern with intellectual integrity and conclude that both independent thought and original scholarship are possible within work that is engaged with nonacademic publics. 相似文献

This article examines the relationship between gender, hostile sexism, benevolent sexism and reactions to a seemingly innocuous genre of sexist humor, the dumb blonde joke. After hearing an audiotaped conversation in which two students swapped dumb blonde jokes, participants high in hostile sexism rated the jokes as more amusing and less offensive than those low in hostile sexism. Among individuals low in hostile sexism, however, benevolent sexism interacted with gender. Specifically, men high in benevolent sexism found the jokes significantly more amusing and less offensive than either women in the same group or men low in both hostile and benevolent sexism. This study replicates and extends previous research examining the relationship between hostile sexism and the enjoyment of sexist humor, and underscores the possibility that benevolent sexism may represent qualitatively distinct attitudes for men and women. 相似文献

Breast cancer remains a highly prevalent and extraordinarily stressful experience for hundreds of thousands of women each year in the United States and around the world. Psychological research has provided a picture of the emotional and social impact of breast cancer on patients' lives, and of factors associated with better versus worse adjustment. Psychosocial interventions have been beneficial in decreasing patients' distress and enhancing their quality of life. Recent research also suggests that psychological factors may be related to potentially important biological disease-related processes. In addition to providing an understanding of the psychological factors in breast cancer, research in this area has provided a framework for research on adaptation to health-related stress in general. 相似文献

Two children with autism were trained in US geography using a match to sample procedure. Different testing procedures commonly used in stimulus equivalence research were compared, including some conditions with reinforcement for responding to enhance motivation. Both children were able to master the trained geography relations and emergent stimulus relations were also noted. All three testing procedures produced similar effects, suggesting that incorporation of procedures to enhance motivation to respond does not invalidate testing in a stimulus equivalence preparation.
