The existence of specific developmental disorders such as dyslexia and autism raises interesting issues about the structure of the normally developing mind. In these disorders distinct cognitive deficits can explain a range of behavioural impairments and have the potential to be linked to specific brain abnormalities. One possibility is that there are specific mechanisms dedicated to particular types of information processing. These mechanisms may function independently of more general information processing systems and may have a distinct anatomical basis in the brain. 相似文献

Examined the effectiveness of an HIV intervention program among 151 adolescents ages 13 to 24 years who were randomly assigned to (a) seven sessions of 1.5 hr each (10.5 hr); (b) three sessions of 3.5 hr each (10.5 hr); or (c) a no-intervention condition. Using cognitive-behavioral intervention strategies, social skills and HIV-related beliefs, perceptions, and norms were targeted in both the three- and seven-session, small-group intervention conditions. Regression analysis indicated that over 3 months, the number of unprotected risk acts and the number of sexual partners were lower in the seven-session condition compared to the other conditions. Factors mediating risk acts changed in a complex manner: For example, perceived vulnerability increased for those with initially lower vulnerability scores among youths in the seven-session condition compared to others. Self-approval of condom use was also higher for those with initially low scores in the seven-session compared to the three-session condition. Self-efficacy for risk avoidance and condom use was significantly higher in the three-session condition for those with initially low scores compared to other groups. On the role-play measure, those with higher baseline scores in the low-pressure situation improved significantly only in the three-session intervention; in the high-pressure situation, the participants reported significantly higher scores in the seven-session intervention, and those with higher scores improved the most. Results suggest the importance of multisession HIV intervention programs to be delivered with fidelity in community settings. 相似文献

A nationally representative sample of Danish males finishing school in 1989, or shortly before, with a studentereksamen (the highest qualification in the Danish school system) was found to score generally lower on a battery of four cognitive tests than a comparable sample of Danish males who had taken the same tests shortly after finishing school in the late 1950s or early 1960s. This decline appears attributable to the increasing proportions of students who obtain the stundentereksamen and is quite compatible with an overall increase in test scores, also found in our data, for the general population over the same time period. For those who obtain the stundentereksamen , the decline has been most marked in a test of verbal analogies. It has been smaller for tests of logical and spatial reasoning, and scores on a test of numerical ability have actually improved over the 30 years. This differential pattern may be the result of both student changes and auricular changes within Danish schools. 相似文献

The clinical term pseudodementia has remained a permanent nosological entity in the literature for over 100 years. Indeed, recognition of the fact that clinical symptoms associated with reversible neuropsychiatric conditions can mimic irreversible disorders was known as early as the middle of the 19th century. The importance of the term lies in the inherent assumption that the presenting dementia is not real, or is at least reversible, and therefore treatable. Nonetheless, there continues to be controversy regarding the validity and appropriate clinical use of the term. This article reviews the evolution and clinical utility of the term pseudodementia and attempts to redirect investigative efforts toward an understanding of the neuroanatomical substrates that underlie depression and cognitive impairment in the elderly. Based on a critical analysis of the relevant literatures, a subcortical-frontal neuroanatomical substrate of late-life depression is supported. Further, the presence of leukoaraiosis, as measured by magnetic resonance imaging, is proposed as a potential neurobiological marker that contributes to the depressed mood, cognitive impairment, and later cognitive deterioration of some elderly depressed. 相似文献

Until recently, little attention has been paid to the possibility of cognitive deficits in patients with disease or failure of major organs such as the liver, kidney, or heart. However, there is a growing awareness that major organ failure often has neuropsychological sequelae. These sequelae may at times be quite subtle and not detectable under gross. examination. Nevertheless, even subtle deficits may have a major impact on adherence to medical regimens, psychosocial adjustment, and quality of life of patients. Neuropsychological assessment has a potentially valuable role to play both in research and in clinical work. It can be useful in adding to our knowledge of the cognitive effects of various types, severity and duration of major organ disease, as well as sequelae associated with treatment. It also is a potentially valuable clinical tool for identifying cognitive deficits that will affect the quality of life and probability of survival for organ failure patients. 相似文献

Age differences in adults' processing of a dialectical or nondialectical prose passage were explored. Twenty young and 20 older adults read a dialectical or mechanistic passage and were tested for free recall and recognition after a 30-min delay (filled with vocabulary and paradigm belief scale). Older (vs. young) adults had significantly lower formistic and mechanistic scores and showed greater relative preference for relativistic and dialectical beliefs (paradigm scale). There were no age differences in amount of free recall or number of correct responses (hits) on recognition, but older adults produced more spontaneous dialectical distortions in recall of the mechanistic passage and more paradigm-congruent false alarms on recognition. There was also a move from absolute toward dialectical thinking on the paradigm scale and, among males, on the recognition measure. Dialectical scores (paradigm scale) were positively correlated, and mechanistic scores negatively correlated, with number of dialectical distortions on free recall (mechanistic passage), while dialectical scores were positively correlated with number of dialectical false alarms (dialectical passage). 相似文献
