Many deaths from cardiopulmonary arrest can be prevented by the prompt and effective administration of cardiopulmonary resuscitation (CPR). In this study, we examined the standard training program for teaching CPR to emergency medical technicians (EMTs). We developed an alternative experimental program whereby the behaviors involved in CPR were assessed easily and in greater detail. This assessment provided the basis for a system in which effective CPR skills were reinforced and problems were corrected. Subjects who were trained in CPR according to this experimental program performed more effectively than subjects in the standard program. In addition, retention (maintenance) measures indicated that experimental subjects continued to perform well, often more effectively than professionally employed EMTs. 相似文献

Scores on the State-Trait Anxiety Inventory for children in a longitudinal study of pubertal Spanish youth. 总被引:4,自引:0,他引:4

Changes in scores on the State-Trait Anxiety Inventory for Children for a sample of 534 pubertal adolescents were longitudinally studied over a period of 4 years. Biological development and other variables were investigated. For the 310 boys, A-trait scores decreased significantly with age. The 224 girls showed significantly higher scores than boys in all years of the study. No significant relationship was found between anxiety and pubertal maturity. The year-to-year persistence in symptomatology of anxiety ranged between 55.6% and 66.1% for girls and between 48.5% and 53.1% for boys. Girls showed bi- and tri-annual persistence between 31% and 50%, and boys between 13% and 27%. Neuroticism scores formed the best predictor of A-trait scores. Symptomatology of anxiety is not transient during early adolescence, so personality may provide a risk indicator in the development of anxiety. 相似文献

We described a patient with a dramatic deficit of both word comprehension and naming but with good preservation of visual pictorial semantics. On word-picture matching, his performances were slightly better than expected based on the observed lexical semantic disorder; in addition, the patient, who maintained good preservation of his underlying phonology, showed a tendency to point to the picture phonologically related to the target. In order to interpret these data, we advanced the hypothesis that the patient, in spite of his virtually complete inability to name, would be able, in a word-picture matching task, to "covertly" (i.e., preverbally) retrieve the name from the picture and to use this name to attempt a match with the phonological form of the stimulus word. This mechanism, that we called "phonological" comprehension, would allow the identification of the correct target and would explain the choice of the phonologically related foil that was sometimes selected. 相似文献
