An index is proposed to measure the extent of agreement of the data of a sociometric test with another test made at an earlier time or on another test criterion. The index is used to define an index of concordancebetween the two tests. It is shown how the index may be used for either individuals or groups. Tests of the hypothesis that agreement is random are given for all cases and applied to an example.Work done under the sponsorship of the Office of Naval Research. 相似文献

This project investigated the effect of a new recreational activity on the generally low level of engagement of residents in two lounges of a Local Authority home for the elderly physically frail. Indoor gardening sessions open to all residents were held on one afternoon each week in the dining room of the home. In the setting-up phase a researcher ran the gardening sessions, developed a set of written instructions on how to organize the activity and used these. plus performance feedback, to train a volunteer to run the sessions. The experimental phase evaluated the residents' level of engagement during the weekly gardening sessions and on another afternoon each week when there were no planned recreational activities. The results show that indoor gardening was very successful in producing sustained activity by the residents attending and that engagement of the residents was significantly higher on gardening than on non-gardening days. 相似文献

The effect of suggestive questions on 3- to 5-year-old and 6- to 8-year-old children's recall of the final occurrence of a repeated event was examined. The event included fixed (identical) items as well as variable items where a new instantiation represented the item in each occurrence of the series. Relative to reports of children who participated in a single occurrence, children's reports about fixed items of the repeated event were more accurate and less contaminated by false suggestions. For variable items, repeated experience led to a decline in memory of the specific occurrence; however, there was no increase in susceptibility to suggestions about details that had not occurred. Most errors after repeated experience were intrusions of details from nontarget occurrences. Although younger children and children who were interviewed a while after the event were more suggestible, respectively, than older children and those interviewed soon after the event, repeated experience attenuated these effects. 相似文献

The link between body image and eating disorders has been extensively discussed, but investigations using nonclinical populations have not been systematically reviewed. In this article, a model to guide future researchers has been provided, and an attempt has been made to organize and synthesize the existing findings, with special attention to gender differences. Future researchers should more carefully delineate behavioral, emotional, cognitive, motivational, and evaluative components of body schema and should explore the relationship between body schema and outcomes other than eating disturbances. Conclusions in this review include the following: (a) Verbal measures of body schema are more successful than visual assessment tools; (b) measures of body distortion have been less successful than measures of dissatisfaction; (c) gender differences are prevalent; (d) behavioral outcomes can be successfully predicted; and (e) pubertal development plays a critical role in the gender differentiation of body schemas. 相似文献

“A Tiger Behind, and Coming up Fast”: Governmentality and the Politics of Population Control in China 总被引:1,自引:0,他引:1
China has a growing superaging population, known colloquially as a tiger behind. This phenomenon has been traditionally analyzed by conventional social science methodology as a question of resource allocation to a burgeoning elderly population. However, population policies in China have emerged as key vehicles used to legitimize and position the identities that older people adopt. They contain specific yet continually changing technologies that function to mediate relations between older people and the Chinese state. They also represent an increase in state control that can be exerted on lifestyles in family form and older age and thus, the wider social meanings associated with that part of society and lifecourse. This article briefly summarizes the empirical detail and context of superaging in China, presenting an original theoretical analysis based on a reading of the work of Michel Foucault. The interrelationship between the Chinese government and older people is identified in terms of Foucault's (1978) and Rose and Miller's (1992) concept of governmentality. The article highlights how and why older people are the subjects of the Chinese state's gaze. 相似文献

Kinetic output: A conceptual, dimensional and empirical analysis 总被引:1,自引:0,他引:1
A dimensional analysis permitted behavioral frequency, duration and available time to be collapsed into a singular dimensionless expression called Kinetic output (K(o)). An empirical analysis across several behaviors in some human subjects showed that the derived index of behavioral output, K(o), was more likely to exhibit less variability than rate or duration measures of the behavior. As a reduction in variability is synonymous with finding an increased order, the results tentatively support the notion that behavior may exhibit conformity at a previously undetected level. One major implication of the K(o) formulation is that divergent frequency and duration performances are interpretable as reflecting alternate forms of the same equivalence. 相似文献

Various recently developed brain imaging techniques used to assist in the diagnosis of dementia are reviewed. The methods reviewed are x-ray computed tomography scan imaging, magnetic resonance imaging, positron emission tomography, and the older techniques of pneumoencephalography and radioisotope cisternography. It was concluded that while these techniques often offer excellent diagnostic information, none of them provides a definitive characteristic image for Alzheimer's disease. 相似文献

Social Psychology and the Stimulation of Recycling Behaviors: The Block Leader Approach 总被引:4,自引:0,他引:4
Recycling has been touted as an important part of the solution to solid waste problems, yet most citizens still do not recycle, even when recycling is made easy by curbside pickups. This field experiment was designed to increase participation in a city-sponsored curbside recycling program. Citizens who consistently recycled with the city program were approached and asked to be "recycling block leaders." Those who agreed were instructed to give approximately 10 nonrecycling neighbors a persuasive communication advocating recycling and special recycling bags. A second treatment group (of nonrecycling households) had bags and the communication left at their door. Results indicated that the curbside recycling of the two experimental groups differed significantly from one another (with the block leader group recycling more), and both differed significantly from a control group receiving no treatment. A discussion of past recycling intervention research and its feasibility for community application is included. 相似文献

Although there is agreement that marital problems are associated either directly or indirectly with particular child behavior problems, there is disagreement about the types of marital conflict associated with these problems and the differential effects on boys and girls in clinic and nonclinic samples. We examined the relationships among mothers' ratings of marital adjustment, parenting disagreements, and three child problem factors (aggression, anxiety, and immaturity) after the child's age and family socioeconomic status were controlled. These relationships were compared with samples of boys and girls (3 to 8 years of age) from clinic and nonclinic populations, revealing that parenting disagreement predicted aggression in all groups and that both marital adjustment and parenting disagreement predicted anxiety in boys. Neither marital variable predicted immaturity. Possible reasons for the results (including methodological limitations of the present data) are discussed.Thanks to Merryl Reville and Kath Faulkner, Monica Smith and Dr. Bill Bor of Queensland Division of Child Guidance, and Pat Roberts of the Lady Gowrie Child Centre for their help with subject recruitment.
