Eighteen women participated in a research project involving two phases: (a) an interview regarding weight history and exercise patterns, and (b) a series of exercise sessions followed by discussions of participants' reactions to them. The data were analyzed using inductive analysis techniques, and results of the analysis were discussed with participants for collaborative validation of the interpretation. Profiles of selected participants and themes that emerged are described. The participants varied in age and body size and had diverse backgrounds, interests, and abilities, but their shared experience of social disapproval based on body size was shown to affect their perceptions of exercise programs and their decisions about participation. 相似文献

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

Three librarians who have extensive experience working in libraries or for publishers, vendors, or consortia presented an informal discussion on librarian–vendor relationships. The audience was encouraged to participate. Problems were articulated; speakers and audience members contributed suggestions for better approaches or behaviors when handling difficult situations. 相似文献
