Three studies investigated whether requiring eyewitnesses to provide multiple accounts of a crime prompted them to exhibit more accurate and complete recall (i.e. hypermnesia) or towards providing more inaccurate and confabulated testimony. Subject-witnesses viewed videotapes enacting several types of crimes. Subjects exhibited hypermnesia in two studies in which they were asked to provide accounts of the incident via a free-recall procedure. Indeed, there tended to be roughly a 10–20 per cent increase in the number of facts accurately recalled from the initial interview to the third. The number of incorrect recollections and confabulations did not reliably increase. In the second experiment, hypermnesia was observed even when eyewitness memory was degraded by delaying the initial interview until a week after the witness viewed the crime. In a third study, which employed a multiple-choice questioning procedure, subjects exhibited neither hypermnesia nor heightened incorrect responding. Discussion centres on possible factors influencing the hypermnesia effect and implications of the present research for theory on hypermnesia. 相似文献

Brief multielement designs were used to examine the effects of specific instructional strategies on accuracy of academic performance during outpatient evaluations of 4 children with learning disorders. Instructional strategies that improved accuracy on academic tasks were identified for all participants. These results suggest that the application of experimental analysis methodologies to instructional variables may facilitate the identification of stimulus prompts that are associated with enhanced academic performance. 相似文献

The present study sought to extend our knowledge of dysphoric adolescents' dyadic peer interactions. Thirty female dyads (ages 13–17) were videotaped interacting during both a structured and an unstructured task. Fourteen of the dyads were each comprised of a dysphoric girl and a nondysphoric girl; the remaining dyads were comprised of two nondysphoric girls. Girls were considered dysphoric if they scored 10 or higher on the Beck Depression Inventory. Dysphoric subjects evaluated their performances more negatively than nondysphoric subjects and rated their partners more negatively overall. The partners of the dysphoric girls were viewed by raters as less positive and less happy. They saw the dysphoric teens as making more critical comments and evaluated them more negatively overall. There was also a tendency for these girls to reject their dysphoric partners and to become more passive during the unstructured task. The findings indicate that dysphoric adolescent girls evoke negative reactions from peers and negatively influence their peers' behavior. These negative reactions from others may lead to further difficulties in negotiating the developmental tasks of adolescence. 相似文献

Greater longevity has increased the years that adult children share with their older parents, yet it creates the potential for family stress situations that may be amenable to counseling intervention. In this article, the authors examined an attachment theory perspective for conceptualizing adult child—older parent issues by introducing the basic constructs of attachment theory and by demonstrating how the theory and its related research can be applied to adult children's struggles with older parental issues. 相似文献

Hemispheric processing, expressed as mean reaction time to various visual stimuli presented to the left and right visual fields, was investigated in eighteen stuttering and nonstuttering children. Tachistoscopic procedures were used to present linguistic stimuli (words and nonwords) as well as nonlinguistic stimuli (familiar and unfamiliar geometric figures) to the visual fields. Subjects responded by pressing a telegraph key when they perceived a real word or a familiar geometric figure. They were to make no response when they perceived nonwords or unfamiliar geometric figures. Faster reaction times were taken as an index of the most efficient or dominant hemisphere for a given task. No significant differences were found in mean reaction times for groups, visual fields, type of task, nor any of their interactions. Likewise, the data on accuracy also did not suggest that a larger proportion of stutters responded more accurately when linguistic stimuli were presented to the right hemisphere. Based on mean reaction times and on accuracy data, the stuttering and nonstuttering children performed with similar efficiencies and processing patterns. 相似文献

A table of criterion values for use with the theory of signal detection (TSD) is presented. Criterion values (β) are presented for varying proportions of hits and false alarms. A brief explanation of signal detection theory is given, and the measures for sensory sensitivity (d′) and response criterion (β) are described. 相似文献

Multiple physiological measurements as well as a self-assessment of arousal was made in eight men on the first, third, and fifth days of bedrest. On the third day, additional measurements of performance on memory and dexterity tasks were made. Univariate analysis did not reveal any physiological variable to either predict subsequent performance well or to co-vary acutely with it; however, self-rating scores did prove to be useful predictors of subsequent performance. Principal components analysis suggested an“alertness” factor comprised of physiological measures as well as selfratings which helped in predicting better performance. Although the individual patterns of correlations between variables on each of the three test days was variable, even more variability between subjects was found on the performance testing day. We believe this effect of behavioral activation may be due to the injection of common, slow temporal trends into many of the different data sets. 相似文献

An alternating treatment comparison was conducted of the relative effectiveness of oral and total communication training models for teaching expressive labeling skills to three echolalic autistic children. The results of this comparison demonstrated that total communication proved to be the most successful approach with each of the subjects. In addition, the replication of these findings both within and across subjects suggest that total communication may be, in general, the most effective of these two training models for teaching basic vocal language skills to echolalic children. A number of hypotheses are presented that may provide a basis for the demonstrated effect. 相似文献
