Impaired ranking of semantic attributes in dementia 总被引:1,自引:0,他引:1
The present work explored the loss of semantic attributes that is said to occur in dementia. In the first two experiments, subjects had to select attributes that went with concepts like airplane and church. The finding that demented subjects maintained high levels of accuracy when selecting attributes suggested that the semantic content of their concepts was relatively well preserved. The organization of the content was explored in a third experiment by having subjects order attributes according to their relative importance in defining concepts. While demented subjects performed better than chance, they did not rank attributes as well as healthy aged subjects, suggesting a disruption in organization whereby the importance of central attributes is reduced. The hypothesized disruption in organization is viewed in relation to the learning and memory deficit that is the hallmark of the dementias. 相似文献

Seventy-nine psychiatric inpatients were administered a battery of psychometric instruments that obtained information about early parental loss, exposure to family violence, and behavioral problems in themselves and in their first-degree relatives. These variables were correlated with suicide and violence risk measures. Suicide risk significantly correlated with all family variables whereas violence risk correlated with behavioral problems both in oneself and in one's first-degree relatives. Moreover, suicidal and/or violent patients had experienced maternal loss significantly more frequently than the nonsuicidal/nonviolent patients. In the suicidal/violent group, age of patient at death of parents was significantly lower than in the nonsuicidal/nonviolent group. Finally, family violence was significantly correlated with behavioral problems in self and in first-degree relatives. Findings are interpreted according to the authors' theoretical model of aggression regulation. 相似文献
