Relationship of severity of dementia to caregiving stressors 总被引:4,自引:0,他引:4
In studies of individual differences and longitudinal changes in stress and coping among dementia caregivers, assessing severity of patient impairment is critically important. It is proposed that with the progression of dementia, cognitive impairment may steadily increase, but other stressful behavioral symptoms peak at various stages of dementia. Cross-sectional data from 49 caregiving families and longitudinal follow-up data from 48 families suggest that instrumental self-care deficits begin early in dementia, and basic self-care deficits increase with dementia severity, but that many distressing behavioral symptoms decrease in late dementia. Assessments of dementia patient severity should be multidimensional, and increases and decreases in various dementia patient stressors over time should be considered as factors influencing caregiver coping. 相似文献

Frontal lobe dysfunction and memory impairment in patients with chronic progressive multiple sclerosis 总被引:2,自引:0,他引:2
Deficits in semantic encoding have been described in patients with frontal lobe disease who also show memory impairments. As a group, patients with multiple sclerosis (MS) exhibit memory impairment, fail to make effective use of semantic encoding to aid memory, and perform poorly on verbal fluency and concept formation tests which are sensitive to frontal lobe damage. In the present study the semantic encoding capacity of MS patients was measured using a modification of Wicken's release from proactive interference (PI) paradigm. Individual patients varied considerably in the severity of their impairments on verbal fluency, verbal recognition memory and on Wisconsin Card Sorting Task, but even patients who evidenced both memory impairment and signs of frontal lobe dysfunction showed normal release from PI after a categorical shift. Memory disturbances in MS are unlikely to result from an incapacity for semantic encoding, which seems preserved in MS, but may arise instead from deficits in processing information rapidly. 相似文献

Abstract. Developing a scientifically grounded philosophy of cosmic evolution, and using the moral norm of completeness as dynamic harmony, this paper argues that humans are a part of nature in both its conserving and emergent aspects. Humans are both material and cultural, instinctual-emotional and rational, creatures and creators, and carriers of stability and change. To ignore any of the multifaceted aspects of humanity in relation to the rest of nature is to commit one of a number of fallacies that are grounded in a dualistic-conquest mentality. Examples of some new developments in philosophy and theology, metaphorical images, and ritual show how to overcome dualism in favor of a dynamic harmony of humanity within nature. 相似文献

People vary in the extent to which they hold stereotypic beliefs about women. The recently developed Beliefs About Women Scale (BAWS) was used in five investigations to examine the following aspects of people's stereotypic beliefs about women: (Study I) the impact of ethnicity (Hispanics and Anglos) on women's endorsement of traditional beliefs about women; (Study II) the impact of national culture (Mexico and the United States) on women's responses to the BAWS; (Study III) the extent to which U.S. women define women's and men's mental health in terms of stereotypic beliefs about women; (Study IV) the extent to which preferences for counseling orientation influence the beliefs about women attributed to mentally healthy women and men; and (Study V) the impact of national culture (Mexico and the United States) on the beliefs about women ascribed to mentally healthy women and men. The results indicated that (a) U.S. Anglo females disagreed more strongly with traditional beliefs about women than did U.S. Hispanic females; (b) U.S. women expressed greater agreement with traditional stereotypes about women's interpersonal abilities and greater disagreement with traditional stereotypes about women's personal competencies than did women from Mexico; (c) the beliefs about women held by U.S. psychology trainees, and the beliefs about women that they attributed to mentally healthy females, were more nontraditional than those that they attributed to mentally healthy males; (d) particular counseling preferences were associated with the stereotypic beliefs about women that female counseling trainees imputed to mentally healthy males and females; and (e) similarities and differences exist on the beliefs about women that female psychology trainees from the United States and Mexico ascribe to mentally healthy females and males. The discussion focuses on mentally healthy beliefs about women, and the implications of these findings for the delivery of mental health services to women and men from various cultures. 相似文献

The original concept of “social physics” was built on positivist philosophy and scientific method. Evidence from quantum physics
suggests that a postpositivist “social physics” may yet be viable, not because social science should emulate physics, but
because physics is more like social science. The five principles of complementarty, uncertainty, the measurement problem,
nonlocal causation, and participatory collusion are presented in this article to demonstrate the contemporary convergence
of the physical and social sciences into a new social physics.

In this paper, 1 describe psychological guidelines for simplifying medical information — methods to aid the perception and recognition of abnormalities in medical test reports. These techniques resemble natural human editing strategies outlined in prospect theory. The methods pre-edit data as humans do but to reduce human effort. I review empirical studies assessing these techniques and discuss needs for further research. 相似文献

Employment demographics and attitudes that predict preferences for alternative pay increase policies
Dr. Daniel J. Koys Timothy J. Keaveny Robert E. Allen 《Journal of business and psychology》1989,4(1):27-47
A survey of 942 university staff employees shows that performance and cost of living are preferred over seniority as criteria upon which to base pay increases. Multiple regression analysis reveals that preferences for performance-based pay increases are most strongly related to perceptions that merit pay does not decrease co-worker cooperation, perceptions that performance differences exist among co-workers, employment in white collar jobs, and never having belonged to a union. Preferences for seniority-based and cost of living-based pay increases are most strongly related to the perceived need for a union, perceptions that merit pay reduces cooperation, education level, and gender. In addition, preferences for seniority-based pay increases are related to years of service.An earlier version of this paper was presented at the 1989 meetings of the Midwest Academy of Management. 相似文献

Some properties are discussed of regular polygons that may result from angular homeostatic processes in stable orbit. To characterize these homeostatic polygons we need to discuss the winding number, the sidedness (integer, fractional and irrational), multiplicity, envelopes, and density. A regular (i.e., equilateral, equiangular) polygon may be closed in one revolution about its unique center, in multiple revolutions, or not at all. A homeostatic polygon can be generated only if all vertices are included in a single polygon, which occurs if and only if the number of vertices and the number of revolutions required to complete the polygon are relatively prime. For the homeostatic polygon to have a finite number of sides (without repeating itself) the angle subtended by any two successive vertices at the center must be a rational multiple of 2. Biological implications of these properties are illustrated. 相似文献
