This study examined attentional processes underlying skilled motor performance in threatening situations. Twenty-four trained participants performed a simulated rally driving task under conditions designed either to direct the focus of attention toward the explicit monitoring of driving or a distracting secondary task. Performance (lap time) was compared with a "driving only" control condition. Each condition was completed under nonevaluative and evaluative instructional sets designed to manipulate anxiety. Mental effort was indexed by self-report and dual-task performance measures. The results showed little change in performance in the high-threat explicit monitoring task condition, compared with either the low-threat or the high-threat distraction conditions. Mental effort increased, however, in all high- as opposed to low-threat conditions. Performance effectiveness was therefore maintained under threat although this was at the expense of reduced processing efficiency. The results provide stronger support for the predictions of processing efficiency theory than self-focus theories of choking. 相似文献

The mastery approach to coaching is a cognitive-behavioral intervention designed to promote a mastery-involving motivational climate, shown in previous research to be related to lower anxiety in athletes. We tested the effects of this intervention on motivational climate and on changes in male and female athletes'cognitive and somatic performance anxiety over the course of a basketball season. Hierarchical linear modeling analyses revealed that the athletes in the intervention condition perceived their coaches as being more mastery-involving on the Motivational Climate Scale for Youth Sports when compared to athletes in an untreated control condition. Relative to athletes who played for untrained coaches, those who played for the trained coaches exhibited decreases on all subscales of the Sport Anxiety Scale-2 and on total anxiety score from preseason to late season. Control group athletes reported increases in anxiety over the season. The intervention had equally positive effects on boys and girls teams. 相似文献

The aim of the present study was to develop a system of tables to facilitate interpretation of the McCarthy Scales of Children's Abilities. Tables are presented that organize the McCarthy subtests according to Bannatyne's, Sattler's, and Meeker's systems of interpretation. In addition, tables that organize the McCarthy Scales into categories that reflect factors likely to influence various subtests are presented. These tables will provide a more structured approach to McCarthy interpretation and a straightforward empirical method for generating hypotheses regarding individual strengths and weaknesses in intellectual ability. 相似文献

Zarske, Moore, and Petersen's (1981) article that examined the factor structure of the WISC-R for “diagnosed learning disabled” children was critiqued. These authors concluded that the WISC-R “is an appropriate measure of general intellectual abilities” (p.407), but the present author suggests that this conclusion does not follow from their factor analytic data. The makeup of the sample also is questioned, and implications of their findings for the practitioner are discussed. 相似文献

This study investigates the efficacy of a social skills training program with seven mildly handicapped students across three school settings: regular classroom, special education resource room, and recess. It was found that social skills training generated improvement on both pre-post measures and behavior ratings. Improvements were maintained 2 weeks after treatment was discontinued for seven students. All students' performance generalized from resource room to regular classroom settings; only four students' performance generalized to the recess setting. 相似文献

This single-subject, experimental research design examined the efficacy of treating severe, long-term selective mutism in a 9-year-old male using shaping, multiple re-inforcers, natural consequences, stimulus fading, and mild aversives. Different treatment regimens were implemented in the home and school environments. A multiple baseline design across settings with changing criterion was used to evaluate the home intervention, and an A-B-A design was used for the school intervention. The home intervention resulted in an increase in the number of verbalizations in each setting and prompted generalization to additional settings. The school intervention increased the number of people spoken to, but the results were not maintained at follow-up nor did they generalize outside of the training situation. Possible explanations for the discrepancy in maintenance and generalization data between the two programs are presented. 相似文献

Dinosaur reconstructions have been exhibited in public for over a hundred years. During that time, scientific and public understanding of these extinct animals has changed considerably. Changes in perception have influenced and been influenced by the three-dimensional reconstructions mounted in museums and galleries, and these in turn have been influenced by the availability and use of mounting materials and techniques. The dinosaur exhibition in The Natural History Museum (NHM) in London contains examples of original, altered, and new dinosaur reconstructions that are described here—two, Gallimimus and Massospondylus, in detail. The final form of any reconstructed dinosaur is often influenced by factors beyond the control of the conservation, preparation, and mounting workers involved. 相似文献
