Following consultation by two psychologists with an elementary school populated primarily by Mexican-American students, absenteeism was chosen as the first problem area to attempt to change. A between-groups experimental design was used to evaluate the effect of contigent rewards on the students' attendance. Analysis of the data showed no improvement in attendance. The results of the study were discussed in terms of (1) a more thorough behavior analysis of the absenteeism problem, (2) methodological restraints of a between-groups experimental design, (3) the need for consultants to be familiar with the community in which they work, and (4) relatedly, the success of the local school psychologist in implementing behavior modification programs. 相似文献

Using a metric of syllabic complexity derived from a syntagmatic theory of syllabic production, in which syllabic recoding expands a syllable into an optional initial consonant group and an obligatory vowel group, MacKay (1974) examined the relationship between the complexity of syllables and their durations in a task of rapid repetition. He concluded from spectrographic measurements of the test syllables that the complexity metric was a good predictor of the syllable durations, and hence syllable repetition rates. The present report demonstrates that comparable, if not better, predictions are made by a simpler theory based on the recoding of syllable structures as series of CV combinations, with appropriate reductions of C or V segments. 相似文献

Recently, a nonparametric technique called bootstrapping has been recommended over the more well-known analysis of variance (ANOVA) for analyzing repeated measures data. Advocates cite as bootstrap’s advantages over ANOVA the fact that the former uses distributional information and is free of normal theory assumptions. The present study used a computer simulation to compare the two techniques calculated using data sampled from normal and nonnormal distributions. The parametric test had adequate control of Type I error rates; the nonparametric test had overly liberal Type I error rates and therefore is not recommended. 相似文献

Medical students who had to undergo an important set of examinations were asked to fill out two questionnaires, the first early in the term, the second 1 or 2 wk before the exams. Students whose anxiety increased substantially between the two questionnaire administrations reported that their thoughts had become more intrusive on a number of parameters including distress, frequency and dismissability. Subjects whose anxiety increased only moderately or not at all reported correspondingly smaller changes in intrusiveness. There was considerable stability in reported cognitions over time, but changes in anxiety were related to changes in reports of thought content. The perceived probability of negative outcomes did not vary over time. These results indicate that changes in anxiety levels over time are related to several parameters of intrusiveness as well as thought content. 相似文献

Sixty-three generally anxious subjects were assigned to anxiety management training, applied relaxation training, relaxation-only, placebo and untreated control conditions. After 6 weeks of treatment, anxiety management training led to reductions on a variety of self-report measures of state and trait anxiety and decreases in maladaptive cognitions during a laboratory stress procedure. On several measures, subjects in anxiety management training differed from relaxation-only and placebo subjects as well as untreated controls. However, treatment effects did not extend to performance and physiological measures of anxiety. Applied relaxation training, which in contrast to anxiety management training lacks structured rehearsal involving the recognition and reduction of tension cues during the treatment sessions, resulted in less consistent decreases in measures of general anxiety. 相似文献

Few studies have investigated the extent to which psychosocial/psychological factors are associated with the prediction of deliberate self‐harm (DSH) among adolescents. In this study, 737 pupils aged 15–16 years completed a lifestyle and coping survey at time one and 500 were followed up six months later. Six point two percent of the respondents (n = 31) reported an act of DSH between Time 1 and Time 2. In multivariate analyses, worries about sexual orientation, history of sexual abuse, family DSH, anxiety, and self‐esteem were associated with repeat DSH during the course of the study, but history of sexual abuse was the only factor predictive of first‐time DSH. The findings suggest that school‐based programs focused on how young people cope with psychosocial stressors may offer promise. 相似文献
