Naming and categorical knowledge in Alzheimer''s disease: The process of semantic memory deterioration 总被引:1,自引:0,他引:1
Semantic memory deterioration in Alzheimer's disease (AD) has been theorized to proceed from a loss of object attribute knowledge to a loss of category knowledge. The theory is based on the belief that naming is a computational process requiring object attribute knowledge. It is strengthened by reports that AD patients misname by giving category information and perform poorer on tests of attribute than category knowledge. The purpose of this study was to test the theory's validity by administering naming and category knowledge tasks to AD and normal elderly control subjects. Results revealed a theoretically unexpected outcome, that is, naming became easier relative to the recall and recognition of category information. 相似文献

This study tests predictions that adolescent psychopaths are hyperresponsive to rewards (Quay, 1988) and deficient in passive avoidance learning (Newman & Kosson, 1986). Forty male adolescent juvenile offenders were divided into psychopaths and nonpsychopaths using cluster analysis. Subjects were administered a passive avoidance learning task which required learning when to respond to cards associated with either reward or punishment. Results showed a greater responsivity to reward in psychopaths, with no group differences in passive avoidance errors. Results lend support to the view that psychopaths tend to focus on the prospect of reward under conditions of mixed incentives and, when sufficiently motivated, are capable of improved performance. Together with findings of recent psychophysiological studies, these results suggest that adolescent psychopaths may have latent abilities which could have treatment implications.The authors are greatly indebted to the boys and staff of the testing institution for their kind cooperation in this study. Thanks are also due to Dr. Rand Wilcox for statistical consultation and Cheryl Eurton and Marni Ayers for assistance in data coding. 相似文献

Based on self-determination theory (Deci & Ryan, 1985, 1987, 1991), we assessed the effect of controlling strategies and restricted choice options on students' performance on analytic reason problems. Subjects in the controlling-directives condition were told by their teacher that a given strategy was the way students should solve a set of analytical problems. Although subjects in the noncontrolling-directives condition were taught the same strategy, they were encouraged to use any strategy they chose to solve the identical problems. The results indicated, as predicted, that subjects in the controlling-directives condition performed significantly worse than subjects in the noncontrolling-directives condition on a subsequent set of analytic reasoning problems, when tested by an experimenter who was unaware of a subject's condition. Interestingly, subjects in the controlling-directives condition regarded the teacher as qualitatively more competent than noncontrolling-directives subjects, in spite of their poorer performance. Furthermore, feelings about the task, mood differences, or perceptions of performance as a function of condition did not account for these findings. The data are discussed as they relate to the theoretical and practical import of the deleterious use of controlling techniques in a number of contexts, as well as adults' erroneous beliefs about controlling strategies.This study was funded in part from a grant from the Spencer Foundation and an NIMH grant to the first author. 相似文献

This paper describes a new infant-based measure for assessing infant attachment to a sibling during a modified strange situation procedure. Research has demonstrated that young siblings often form a special relationship and that they prefer to interact with one another rather than with an unfamiliar peer. Also it has been shown that older siblings can respond appropriately to the distress of an infant. Research on relationships has moved from frequency counts of discrete behaviours towards more global measures of the ways in which behaviour is organized. These have tended to focus upon the older child as caregiver or the influence of the mother-child relationship on child-child interaction during the strange situation. The main findings of previous studies are presented. This paper describes a new method for measuring sibling attachment. Advantages of the new scoring system over previous procedures are that it utilizes ethological attachment theory, it is infant-based, it allows for a variety of infant reactions to reunion with the older sibling, and it focuses on overall patterns of behaviour rather than tallies of frequences. 相似文献

This study examined psychiatrically disturbed adolescents' history of exposure to suicide attempts, completions, and other deaths in relation to attitudes about life and death. A primary goal of the study was to study the mediating processes involved in the impact of loss on suicidality. Adolescents who experienced the suicide of a friend or immediate family member reported a weaker attraction to life and stronger attraction to death than adolescents lacking this experience. Exposure to attempted suicide resulted in attitudes indicating a stronger attraction to death and repulsion by life. We conclude that a comprehensive history of loss and assessment of current attitudes toward death are important aspects of evaluation and subsequent treatment of at-risk adolescents. 相似文献

Abstract : Although the question of survival is on the mind of most mainline congregations in the United States, the real crisis facing the churches is one of identity. After briefly reviewing three theological paradigms for the church (Word‐event, communion, and missio dei), I propose that the question of the church's identity is best answered by returning to the “story of the church,” which properly “starts with the Spirit,” and by reclaiming a concept of the church as a Spirit‐breathed people who are called and sent. 相似文献

African American faith communities are an important source of social capital. The present study adapted a theory-based social capital instrument to result in religious (e.g., from organized worship) and spiritual (e.g., from relationship with higher power) capital measures. Data from a national sample of 803 African Americans suggest the instruments have high internal reliability and are distinct from general religiosity. Measurement models confirmed factor structures. Religious capital was positively associated with self-rated health status. Religious and spiritual capital were negatively associated with depressive symptoms, but these associations largely became nonsignificant in multivariate models that controlled for demographic characteristics. An exception is for spiritual capital in the form of community participation, which retained a negative association with depressive symptoms. These instruments may have applied value for health promotion research and practice in African American communities. 相似文献
