Performance on the Wechsler Adult Intelligence Scale was followed over two 5- to 6-year intervals for essential hypertensive Ss (EH; n = 22) free from medical complications and for normotensive Ss (N; n = 20). EH were treated with adrenergic beta-blocking drugs, diuretics, or both. Mean age was 46 years (SD = 12.6 years), initially (Time 1). Results were unaltered by adjustment for initial age. N improved modestly on the Verbal scale, from Time 1 to Time 2 only. EH neither improved nor declined on the Verbal scale. Scores remained unchanged for both EH and N Ss for the Performance scale. Overall, and at Times 2 and 3, Verbal scores were lower for the EH group. It was concluded that neither decline nor improvement in cognitive function over time are necessary outcomes of modest, carefully treated, uncomplicated hypertension in the middle years. 相似文献

The effects of electromyographic (EMG) biofeedback on reaction time (RT) and movement time (MT) were investigated utilizing 42 right-handed, male subjects from a university population. Subjects were randomly divided into three groups, a control group and two experimental groups. Both experimental groups were exposed to their EMG signals from their triceps brachii during the task, one experimental group received written information explaining the purpose of the EMG was to improve performance through biofeedback. Reaction times of the first block of 25 trials were significantly faster than those on the subsequent three blocks of trials for all groups. This provided evidence of learning. No other significant effects for reaction times were observed. Mean movement time for the EMG-only group was significantly slower than the means of either the Control group or EMG-Biofeedback group, with no difference between the latter two. The differences between experimental groups may have been related to alteration of strategy, anxiety, motivation. 相似文献

Rural America. Unique opportunities for health care delivery and health services research 总被引:1,自引:0,他引:1

A general deterioration is occurring in the quality of life of rural Americans, and it is affecting the quality of health and mental health service delivery. About 24% of the U.S. population lives in nonmetropolitan areas where the citizens are older, less well educated, have lower incomes, and are more homogeneous in terms of race and ethnicity. Medicare and private insurance discriminate against rural services in their reimbursement policies, and there is a shortage of health personnel in rural areas. However, there has been renewed congressional action to meet rural needs. Both the House and Senate have established rural caucuses, and an Office of Rural Health Policy has been established in the federal executive branch. Legislative successes were achieved between 1985 and 1988. Rural initiatives will provide psychology with unique opportunities in the next several years. 相似文献

Interrelationships among measures of intelligence and spontaneous flexibility were examined at two age levels using a multitrait-multimethod matrix design and other multivariate procedures. Measures of intelligence were Ravens Matrices and WAIS Vocabulary, WAIS Digit Symbol, and WAIS Similarities. Blots, Hidden Pictures, Brick Uses, and Impossibilities were used as measures of spontaneous flexibility. Subjects were 100 younger (X¯= 19.54,S.D.= 1.23) and 100 older (X¯= 63.99,S.D.= 2.94) men and women tested at two occasions. Adult age differences in factor structure were explored using a maximum likelihood analysis; common variances among the measures were greater for the elderly compared to the younger adults. Findings supported a dedifferentiation hypothesis with regard to both intelligence and spontaneous flexibility. 相似文献

This study identifies the family life education needs of minimally and mildly mentally disabled adolescents as a basis for curriculum development. Respondents were 134 students from 11 school districts in a midwestern state. Through the administration of 50 needs statements, they were asked to indicate the magnitude of need and the extent to which the need was being met. Special education teachers were allowed to assist in reading or interpreting the directions and needs statements. Priority need statements--those with a high need score which were not being met--are related to the decision to parent, careers and work, marriage and parenthood, decision making and goal setting, and resource management. Six clusters or groups of family life education needs were identified: Basic Nutrition, Teenage Pregnancy, Sex Education, Developmental Tasks of Adolescents, Marriage and Parenthood, and Planning and Decision Making. Females reported significantly greater need for information on nutrition, teenage pregnancy, and marriage and parenthood. 相似文献
