Experimentally naive rats were trained to key press on a fixed-ratio 10 schedule of food reinforcement by a completely automatic procedure within a single, 1-hr session. Control procedures demonstrated that the resulting behavior was an operant, under control of the schedule of reinforcement and the specified reinforcing stimulus (food). A simple, combination food-tray operandum, also described, was used as the basis for the training technique.  相似文献

Young Black gay/bisexual men (YBGBM) are affected by contextual stressors—namely syndemic conditions and minority stress—that threaten their health and well‐being. Resilience is a process through which YBGBM achieve positive psychosocial outcomes in the face of adverse conditions. Self‐efficacy, hardiness and adaptive coping, and social support may be important resilience factors for YBGBM. This study explores different profiles of these resilience factors in 228 YBGBM in New York City and compares profiles on psychological distress, mental health, and other psychosocial factors. Four profiles of resilience were identified: (a) Low self‐efficacy and hardiness/adaptive coping (23.5%); (b) Low peer and parental support (21.2%); (c) High peer support, low father support (34.5%); and (d) High father and mother support, self‐efficacy, and hardiness/adaptive coping (20.8%). YBGBM in profile 1 scored markedly higher on distress (= .74) and lower on mental health functioning (= .93) compared to men in the other profiles. Results suggest that self‐efficacy and hardiness/adaptive coping may play a more important role in protecting YBGBM from risks compared to social support and should be targeted in interventions. The findings show that resilience is a multidimensional construct and support the notion that there are different patterns of resilience among YBGBM.  相似文献

Three aspects of voice recognition were investigated in the study reported here: memory for familiar voices, memory for the words spoken, and the relative effects of length and variation in a voice extract on long- and short-term memory. In Experiment 1, recognition memory for the briefly heard voice of a stranger was superior with longer extracts (p<0.01), but increasing vowel variety did not improve performance. This pattern was repeated for short-term memory (p<0.01) in Experiment 2. Scores for the above task correlated significantly (p<0.05) with scores for recognizing well-known voices. In a further test of well-known voice memory in Experiment 3, a weak and non-significant positive correlation (r=0.29) was found between memory for well-known voices and memory for a once-heard voice. Memory for the words spoken did not correlate significantly with memory for the unknown voice itself. The possibilities of a memory-for-voices general ability, and forensic applications of the findings are discussed. © 1997 by John Wiley & Sons, Ltd.  相似文献

ABSTRACT

Research and debate on the importance of spirituality and religion in psychiatry has led to a number of national and international policy initiatives, intended to clarify the boundaries of good practice and improve the way in which such matters are managed for the benefit of patients. Significant amongst these is the 2015 position statement of the World Psychiatric Association, the only such policy statement to date which has been internationally agreed. Preliminary evidence available suggests that this is having good effect in generating professional debate and further national policy initiatives in different countries. There is a need for further research on such policy initiatives to confirm whether or not they have the intended impact upon clinical practice and whether or not this in turn is beneficial for patients.  相似文献

Although electronic devices may enhance the effectiveness of some behavioral interventions for children with autism spectrum disorders, such devices may also give rise to problem behavior such as repetitious button pressing (i.e., object stereotypy). Results of this study showed that a child with autism spectrum disorder only displayed high levels of object stereotypy on an iPad? when presses generated auditory output. Subsequently, results showed that when the participant used the iPad? without auditory output, his stereotypical behavior decreased and his manding for various items simultaneously increased.  相似文献

This comprehensive review synthesizes findings from 29 studies in which students with disabilities utilized behavioral self‐management techniques in inclusive settings. Findings suggest that consistent with 2 earlier reviews of these types of studies, most behavioral self‐management techniques continue to be adaptable in inclusive settings with moderate to strong efficacy. This review identifies strengths as well common limitations of the studies, provides recommendations for future research and practice, and includes behavioral self‐management resources.  相似文献
