Developmental differences among the effectiveness of three spoken reinforcers were evaluated by measuring rate and accuracy of performance on a vowel recognition task. Eighty-seven males were selected from grades 1 to 3, 6 to 7, and 11 to 12 of a predominantly urban, Black, parochial school. The effectiveness of approval and affirmation of correctness was related to grade level for accuracy of performance, but not for rate. For accuracy of performance a decreasing linear trend was found when approval effectiveness was evaluated across grades. For correctness, an increasing linear trend was found. The results were discussed in terms of a developmental hierarchy of reinforcers and information processing.  相似文献

Abstract

Public health agencies regularly survey randomly selected anonymous students to track drug use, sexual activities, and other risk behaviors. Students are unidentifiable, but a recent project that included school-level analysis discovered a school with alarmingly prevalent student suicidality. Given confidentiality protocols typical of surveillance, the surveyors were uncertain whether and how to intervene. We searched literature for duties to warn at-risk groups discovered during public health surveillance, but we found no directly applicable guidance or cases. Reasoning by analogy, we conclude that surveyors should contact the school’s leaders to call attention to its outlier status, but public warning is unwarranted. However, such an ad hoc decision to issue a warning, even if only to school leaders, raises significant practical, legal and ethical issues. National public health and education associations should produce guidance that clarifies ethical and legal duties owed to schools and students involved in population health-risk surveillance.  相似文献

Work as a school psychotherapist in a secondary school is described, with the aim of considering the varied ways in which the provision was used by staff and students. A brief view is given of the history of work in school in the development of psychoanalysis. The creation of an analytic space in school is described. The contribution made to the individual's psychological growth, of a space in which to think, freely emerges; and the ways in which the simplicity of the analytic setting allows its adaptation, by the institution and by the individual, to meet the particular developmental needs of the moment, are shown.  相似文献
