A high proportion of positive responses was obtained from students who participated in three different types of pre-college orientation programs. Small group approaches consistently elicited more favorable responses than assemblies or large groups. Greater faculty involvement resulted in participants' noting an increased academic emphasis. Participants believed they had benefited in some way from programs which varied considerably as to length, activities, organization, and purposes. 相似文献

Two studies investigated biases in the use of base rate information when assessing the probability of a witness' accurate identification of a white or West Indian as a burglar. An adapted version of the Kahneman-Tversky cab problem was used, to provide a social decision in which biases could be measured against some normative standard. Ethnicity of youth (white/West Indian) and nature of base rate (incidental/causal) were manipulated in a 2 × 2 between-subjects design. A significant interaction effect revealed that subjects took no account of the base rate for a West Indian subject, but used the base rate only when it was causal and the youth was white. This ‘prejudice effect’ against a West Indian youth and ‘exoneration effect’ for a white youth were replicated in a second study, using a microcomputer and chronometric analyses. Results are discussed in terms of heuristic decision-making, social schemata, and the cognitive versus motivational bases of bias in the use of base rates. 相似文献

Effects of visual aids on acquisition of selected tennis skills 总被引:1,自引:0,他引:1
The study compared the effects of supplemental visual aids on the acquisition of selected tennis skills. The forehand and backhand drive placement tests of the Hewitt Tennis Achievement Test were used to pretest, midtest, and posttest 55 subjects who were assigned to one of three treatments: control (instructor's verbal feedback only), videotaped replay viewing (with instructor's feedback), and loop-film viewing (modeling, with instructor's feedback). Each received 1200 min. of instruction. There were no statistically significant differences among groups; however, empirical evidence suggested that the use of videotaped replay and loop-film technique has merit and might be given consideration for use in instructional settings. 相似文献

Traditional approaches to group therapy with latency-age children have stressed activity and nonverbal therapeutic interventions. These approaches originated in the 1940s with Slavson's activity aroup therapy. A review of the literature of the past 25 years reveals that many clinicians have increasingly employed verbal techniques with latencyage groups. Most such reports describe groups for latency-age out-patients. In this paper, a verbal, interpretive technique for group therapy with latency-age inpatients is described. Clinical vignettes are included to illustrate this technique. Our experience suggests that such a technique can become an integral part of the inpatient treatment program for the latency-age child. 相似文献

Study of adolescent violence has been impeded by failure to distinguish among the circumstances in which youth engage in violent behavior. The present study investigated MMPI profiles of 36 adolescent murderers and a control group of 18 adolescents charged with larceny. Homicide cases were subgrouped into those who committed homicide secondary to another crime (e.g., robbery or rape) and those who acted in the context of interpersonal conflict with the victim. While there were no significant differences between homicide and larceny groups, crime and conflict subgroups were significantly different on scales F, Hs, Hy, and Sc. 相似文献

The validity of the Threat Index was examined in a study of 42 students and 15 HIV+ clients. When completing the Threat Index, subjects rate the self and death on 30 bipolar adjectives. A count is made of the number of times the same adjective poles are used to describe the self and death. Uses of the same poles are called matches, while uses of different poles are called splits. The Threat Index is based on the assumption that splits indicate threat. Analysis showed that neither splits nor matches were usually threatening and that neither was necessary or sufficient for the experience of threat. These results did not support the validity of the Threat Index. 相似文献
