Detection and identification thresholds were obtained for 6- and 10-year-old normal children and normal adults using five-formant synthesized consonant-vowel ([baHdflrfea]) stimuli. Sixyear-old children were found to have poorer detection than adults, just as they do for pure tones. For the identification task, the slopes of the performance-intensity functions were more shallow for 6-year-old children than for 10-year-olds and adults. Consequently, compared with 10-yearolds and adults, 6-year-old listeners require a greater increase in stimulus intensity above detection threshold to identify these stimuli at a high performance level. The influence of acoustic characteristics of the stimuli on all listeners is also discussed.  相似文献

A one-page questionnaire was sent to 400 elementary school principals nationwide to assess their opinions regarding services of the school psychologist. These elementary school principals indicated that the school psychologist was found to be most helpful when providing the traditional services of psychological testing, personality and emotional assessment, consultation, and screening. Changes in school psychological services desired by the elementary school principals were more time from the school psychologist and an increase in individual and group counseling, preventive mental health, and inservice training. If elementary principal opinion is to be regarded, gross alterations to existing services of the school psychologist are not indicated by the results of this study.  相似文献

Associative and categorical explanations for the organization children and adults display in free recall were tested. It was expected that young children would show output clustering as a function of associations between individual items within categories rather than relationship to the taxonomy itself. Kindergarten, fourth-grade, and tenth-grade subjects were presented with pictures representing the four factorial combinations of high and low interitem association and high and low category relatedness. Each set of pictures could be divided into four taxonomic categories of six items each. Kindergarteners displayed greater category clustering of highly associated items than weak associates. Older subjects showed sensitivity to both organizational dimensions. These data support a hypothesis that young children cluster in recall as a function of associations while older individuals show organizational flexibility which serves to facilitate greater recall.  相似文献

Thirty-eight adults were assigned to three groups: posttreatment hyperthyroid (n=13), low euthyroid (n=12), and high euthyroid (n=13). Physiological and subjective responses to three anxiety-induction procedures—public speaking, personally distressing imagery, and threat of shock—were compared across groups. Although there were differences across stressors for physiological and subjective measures, group differences were not detected. Results are discussed with regard to the risk for residual anxiety following treatment for hyperthyroidism and the possible influence of thyroid function on the etiology or maintenance of anxiety.  相似文献

Most adolescents with chronic illness do not adhere to their regimen. A novel transdiagnostic adaptation of dialectical behavior therapy (dialectical behavior therapy for chronic medical conditions; DBT-CMI) is presented to improve medical adherence in adolescents. The authors describe the approach of DBT-CMI and the model’s conceptualization of nonadherence, with specific focus on the core concepts of non-adherence across illness in adolescence.DBT-CMI has been piloted in two disease groups with preliminary benefit. DBT-CMI lends itself theoretically as a transdiagnostic approach due to specific skills that target core concepts of nonadherence in adolescence. Future research is warranted on the applicability of DBT-CMI across other pediatric medical conditions to replicate findings and examine long-term outcomes.  相似文献

Perceived union support and union instrumentality have been shown to uniquely predict union loyalty. This study was the first to explicitly examine the relation between perceived union support and union instrumentality. Surveys were completed by 273 union members and 29 union stewards. A comparison of 2 models, 1 based on organizational support theory and 1 based on union participation theories, found that the model based on organizational support theory, in which union instrumentality was an antecedent to perceived union support and led to union loyalty and subsequently union participation, best fit the data. The model based on union participation theories, in which perceived union support was an antecedent of union instrumentality and led to union loyalty and subsequently union participation, was not supported. Union instrumentality was related to union commitment, but the relation was completely mediated by perceived union support.  相似文献

Development of the Iowa Infant Feeding Attitude Scale (IIFAS) is described. In Study 1, a set of 17 items was selected on the basis of responses by 125 postpartum women. Analyses of the reliability and validity were then conducted. In Study 2, these analyses were replicated using data from an independent sample of 130 postpartum women. Study 3 involved an analysis of the ability of scores on the IIFAS to predict duration of breast-feeding among a sample of 725 women who had initiated that method of feeding their babies while in the hospital. Limitations of this research and possible future uses of the IIFAS in studies addressing the determinants and consequences of infant-feeding attitudes are discussed.  相似文献
