This study tested the theoretical proposition that the developmental increase in memory span results from a corresponding increase in the use of grouping strategies. With slow presentation, experimenter-provided grouping eliminated the span differences between sixth graders and adults but, while grouping helped first graders more than adults, a sizable difference in digit span remained. With fast presentation, grouping increased the adults' performance more than the childrens'. Another finding was that both groups of children had greater digit spans with fast presentation than with slow. For adults, the reverse was true. 相似文献

The assessment of anxiety disorders in late life is often hindered by the lack of measures specifically validated with older adults. Because anxiety manifestations may vary across age groups, it is important to design new instruments or validate existing measures with older adults. This study examined the psychometric properties of the Beck Anxiety Inventory (BAI) in a sample of 281 older adults who were community-dwelling (82.6%) or living in residential care facilities (17.4%). The mean total BAI score was 6.5 (SD = 7.2), indicating minimal anxiety symptomatology in this older sample. There was a trend for older subjects to score higher. Females scored higher than males, and subjects living in a residential facility scored higher than did community dwellers. Item-total correlations were in the moderate range and the internal consistency of the BAI was adequate (alpha = 0.89). A factor analysis yielded a six-factor structure accounting for 64.6% of the variance, with a somatic factor accounting for the largest portion of the variance (32.2%). Because somatic symptoms are more prevalent with aging, such symptoms should not be weighed as heavily in the total BAI score as cognitive or behavioral symptoms. The findings indicate that the BAI is a useful self-report scale for assessing anxiety symptomatology among older adults. 相似文献

Visual control of locomotion: strategies for changing direction and for going over obstacles. 总被引:19,自引:0,他引:19

Dynamics of gait adjustments required to go over obstacles and to alter direction of locomotion when cued visually were assessed through the measurement of ground reaction forces, muscle activity, and kinematics. The time of appearance of obstacles of varying heights, their position within the step cycle, and cue lights for direction change were varied. Direction change must be planned in the previous step to reduce the acceleration of the body center of mass toward the landing foot to 0. The inability of steering within the step cycle is due to the incapacity of muscles to rotate the body and translate it along the mediolateral axes. For obstacle avoidance, Ss systematically manipulated the gait patterns as a function of obstacle height and position and the time available within the ongoing step. Greater supraspinal involvement in control of locomotion is found. 相似文献

Youth counselling services have sprung up in various parts of Britain over the last few years. Some have collapsed after an initial few months; others have grown steadily, though they tend still to be operating at a reasonably modest level. An analysis of their annual reports and other documents reveals considerable diversity in the nature of the services and the clientele they serve. 相似文献

Two experiments explored individual differences in memory and comprehension for adults presented information on television. Experiment 1 tested the correlation between comprehension of television and reading with young adults. The ability to comprehend these two forms of media was significantly correlated (r = .69). This finding is contrary to results from our previous study with third and sixth graders (Pezdek, Lehrer, & Simon, 1984). Experiment 2 probed two specific individual differences factors as predictors of television comprehension. The results were that good television comprehenders (1) had higher visual/spatial ability, as assessed by psychometric test performance, and (2) were more likely to utilize an imagery-based strategy in the sentence-picture verification task of Clark and Chase (1972) (e.g., “STAR IS ABOVE PLUS”). These results suggest differences in the comprehension processes that operate on information presented in different forms of media. 相似文献

This study investigated hyperactive children's peer relations using the framework of social skills theory. Subjects' (15 hyperactive and 15 control boys aged 7 through 11) knowledge of socially appropriate behavior was assessed using the Social Knowledge Interview (Geraci & Asher, 1980). Additionally, performance of social skills with peers was rated by independent judges during free play, a cooperative puzzle task, and a persuasion task. Peers also rated subjects'desirability as partners for work, play, and friendship. Analyses showed that hyperactive subjects had deficits in knowledge of how to maintain relationships and handle interpersonal conflict, and demonstrated more negative behavior in the cooperative puzzle task than did controls. Hyperactive subjects also were rated by judges as less likely to achieve academic success than controls and were rated by peers as less desirable potential work partners in school. Significant correlations between social knowledge and performance with peers were found. It was concluded that hyperactive boys exhibit deficits both in their social knowledge and in their performance of socially skilled behavior.This research was conducted as part of doctoral research by the first author, under the supervision of the second and third authors. We are grateful for the assistance of Diane Arnkoff, who served on the committee, for her helpful comments and suggestions. Thanks also go to Al Farrell for his statistical consultation. We gratefully acknowledge the support and assistance of the Georgetown University Child Development Center, where the data were collected. 相似文献

The thesis of this paper is that much pathology derives from our inability to deal with our feelings of hurt. The inability to deal with hurt results in the externalization of responsibility which in turn creates victims and dysfunctional behavior. The drama of the externalization of responsibility involves the same individual, the victim, or identified patient, playing three successive dysfunctional roles: the scapegoat, the strawman, and the scarecrow. This view of pathology is basically transactional because the process occurs in a familial context where all the parts of the system are intrinsically related in producing a victim. 相似文献

Thirty-five subjects segmented one of two videotapes of an actor methodically assembling 20 five-page questionnaires. In one sequence, the completion of each questionnaire resulted in a highly visible change in the stimulus fields: The top page of the stack changed from black to white or from white to black with the completion of each questionnaire. In a second sequence the action was identical, but the changing feature was concealed from view. Results disclosed that subjects viewing the tape with the visible change segmented the action on the basis of that change. Subjects viewing the same action without the visible change segmented the behavior into its fine-unit components, despite the fact that the higher-level organization in the behavior was readily understood. 相似文献
