This study examines the relationship between stressors and resources and the functioning of a sample of 515 men and women who had a drinking problem. At a one-year follow-up, both women and men had improved on three functioning measures: alcohol consumption, days intoxicated, and depression. There were no gender differences at Time 2 on alcohol consumption, but men had more days intoxicated and women had more symptoms of depression. The impact of stressors and resources varied by life domain, functioning criterion, and gender. Although the predictors varied, the amount of variance in depression accounted for was the same for women and men. The most striking gender difference was the stronger impact of friendships for women on all aspects of functioning. This study provides support for reconsideration of the stress vulnerability of women and men.  相似文献

This investigation evaluated the use of directed rehearsal to improve the teaching behaviors of four preservice elementary physical education teachers during a teaching practicum. Directed rehearsal consisted of two phases: (a) initial feedback following baseline, review of teaching behaviors, and rehearsal; and (b) rehearsal contingent upon errors made during each lesson. Three teaching behaviors were assessed using a multiple baseline design across behaviors for each teacher. Social validity in the form of the acceptability of directed rehearsal as a teacher training intervention also was assessed using a questionnaire. Results indicate that directed rehearsal was effective in improving the teaching behaviors of the four teachers in this study to 100% correct implementation. In addition, the intervention was acceptable to the teachers and the class instructor.  相似文献

Research and policy-makers have frequently called for operational definitions of child abuse, however neither group has considered including children's perceptions of what constitutes abuse. The purpose of this study was to expand the discussion on definitions of child abuse by examining children's perceptions of physical abuse. This was done by collecting data to begin to document abused children's ratings of the seriousness of various abusive acts and to begin to examine gender and age differences in children's perceptions. The data revealed significant differences in children's perceptions of the seriousness of specific acts of abuse and a significant interaction between age and type of abuse. Although young children generally produced lower seriousness ratings than older children, their ratings were significantly lower on only a few types of abuse. When children's ratings were compared to similar ratings reported in earlier studies of adolescents, community members, and mental health professionals, the children in this study rated the abusive acts as less serious than the adolescents or community members, but very similar to the professionals who work in the area of child abuse and neglect. Although this must be considered a preliminary investigation, the potential implications for various legal and social contexts are discussed.  相似文献

This study investigated the ability of the 51-item Southern Illinois University Speech Situation Checklist (SSC) to differentiate stutterers known to have high levels of speech-related anxiety from nonstutterers with normal levels of speech- related anxiety. Checklist responses of 65 randomly selected subjects (33 stutterers and 32 nonstutterers) were subjected to a stepwise discriminant analysis. The analysis identified a combination of 21 SSC items that had significant discriminative power. Subsequently, the derived discriminant equation achieved 93% accuracy in correctly classifying a hold-out sample of 29 subjects (14 stutterers and 15 nonstutterers). These results strongly suggest that the 21 items of the SSC identified by discriminant analysis may provide an effective screening device for identifying disfluent speakers who experience an abnormal amount of speech-related anxiety.  相似文献

A laboratory experiment was conducted to investigate the effects on reactions to aversive noise of three types of personal control: control over the initiation of noise, control over its termination, and combined control over both initiation and termination. On an attention-to-detail measure which occurred concurrently with noise stimulation, subjects' error rates decreased linearly as degree of control increased. Likewise, on a post-noise measure of task persistence, subjects' performance rates increased linearly across the three conditions as degree of control increased. Results were discussed in terms of Seligman's theory of learned helplessness and deCharms' theory of personal causation, and the motivational effects of personal control were emphasized.  相似文献

Children labeled as under achievers are compared to a matched group functioning normally within the classroom. Factor analyses of the data from several tests reveal that the normal children not only have achieved higher academic performance but also have better learning aptitude. The inference may be made that many underachievers actually have a low general aptitude when carefully measured.This study was supported from funds from the Holden Foundation at the Children's Hospital of Michigan. The authors extend their thanks to Mrs. Barrie Lowy, Mrs. Sheila Kempler, and Ms. Enid Braun.  相似文献

The purpose of this study was to demonstrate the applicability of Fitts' law in predicting the response duration of instruction-specific head movements for a person with severe multiple disabilities. Fitts' law is a motoric algorithm that calculates an index of difficulty (ID) for responses in relation to the variables of stimulus width and stimulus amplitude. Four functional tasks from the learner's current continuing education plans were targeted: photocopying, using a paint well, model painting, and communication symbol sequencing. For each of the four tasks, two sets of indices were calculated by (1) holding constant stimulus width while varying amplitude, and (2) holding constant stimulus amplitude while varying width. Results showed that response duration varied as a function of ID variation.  相似文献
