The major purpose of this study was to investigate aphasic patients' STM for visual stimuli which are difficult to encode. The effect of a varied information rate and information load per item was tested, and so was the relation between primacy and recency scores. The investigation included memory both for content and for position. Each item group in the tests consisted of a time sequence of squares with internal grid lines and a dot in one of the cells. The location of the dot had to be remembered. Both the aphasic group and the control group included 24 persons matched for age. The aphasic group showed a somewhat lower overall score than the normal group. Apart from the interaction between groups and information load, no signifcant interactions were observed. However, there was a systematic tendency over tests towards a relatively lower recency score in the aphasic group. 相似文献

The authors present a short review of the pertinent literature and report on their own neuropsychiatric findings following internal craniocerebral injuries, at the same time drawing attention to the necessity of psychological examination. Statistical comparisons with the international literature are complicated owing to the different classifications used for craniocerebral injuries. 相似文献

Microcomputer-assisted relaxation 总被引:1,自引:0,他引:1
The present pilot study was designed to test the effectiveness of a microcomputer program developed by the authors to induce relaxation and focused attention, which are common to most clinical stress-reduction and hypnotic procedures. A nonclinical sample of 20 adults used the program on an APPLE IIc computer in two 30-min. sessions in a within-subjects design. Repeated measures analyses of variance showed significant decreases in the Spielberger State Anxiety Scale and on a visual analog anxiety scale. Limitations and implications of the study are discussed. 相似文献

This project studied the effects of weather variables and size of the population on minor and major violence rates within six prisons in the Kingston, Ontario, Canada area from January, 1980 through December, 1983. While weather variables have been studied in relation to mood changes within the general population, this study was the first to analyze the impact of weather variables on rates of violence within the prison setting using forward inclusion multiple regression. Analysis showed that population size consistently appeared positively correlated with assaults on other inmates among the male medium-security prisoners during the summer months. In the summer months, temperature tended to be positively related to some minor kinds of offenses, but in the winter months the relationship was negative. Humidity, rain, sunshine hours, snow, and snow on the ground were not consistently related to incidences of minor and major violence. Indices of geomagnetic disturbances had statistically significant inverse relationships with attempted suicide/self-inflicted injury rates among the male prisoners during the summer months. Over 12 months, wind was generally negatively correlated with incidences of major and minor violence among the male inmates. For 6-mo. periods, wind was generally positively correlated with violence rates during the winter months and negatively correlated during the summer months among the male inmates. The findings relating weather variables to violence rates in the women's prison were consistently in opposition to those found for male prisoners during the 4-yr. period. 相似文献

The relationship of characteristics of the social environment to the adaptation of adolescents from high-risk predisposing environments was examined. Specifically, the degree to which adolescents' perceptions of various dimensions of their family and school environment as well as sources of social support related to differential levels of personal well-being and academic adjustment was explored. Multiple regression analyses revealed differences in the salience of the dimensions of the social environment as a function of the particular sphere of functioning under consideration. Implications of the findings for developing a model for understanding the relative vulnerability of individuals at risk as well as of the design of preventive interventions are discussed. 相似文献
