An apparatus suitable for conducting simultaneous or delayed matching-to-sample experiments with as many as eight comparison stimuli is described. Data are presented which indicate that pigeons are capable of performing such a task. It is concluded that the simultaneous matching-to-sample procedure with more than two comparison stimuli is an efficient means of obtaining information about discrimination capacity and that this procedure may be suitable for studying visual perception in infrahuman Ss.  相似文献

Increased demand for applied behavior analysis (ABA) services has increased the need for additional masters-level practitioners and doctoral-level academicians and clinical directors. Based on these needs, the University of Nebraska Medical Center’s (UNMC) Munroe-Meyer Institute has developed a PhD program. The academic structure at UNMC allowed us to create our PhD program in a relatively quick and efficient manner. Our PhD program has many unique features, including (a) close integration of didactic instruction with clinical and research training provided by leading experts in ABA in which students immediately apply concepts introduced in the classroom during coordinated clinical and research practica; (b) structured grant writing training in which students learn to write and submit an NIH-level grant; (c) financial support in the form of a stipend of $23,400 per year, free health benefits, and a full-tuition waiver for up to 12 credits per semester for UNMC courses (a benefits package worth approximately $50,000 per year for an out-of-state student); and (d) encouragement and financial support to present papers at local, regional, and national behavior analysis conferences.  相似文献

National surveys have shown that mental health problems are prevalent in long-term care and suggest that these settings are largely underserved by mental health services. Nursing home administrators are gatekeepers for mental health services in nursing homes. Administrators of Kentucky nursing homes were surveyed regarding their perceptions of mental health problems, current and future services use, satisfaction with services, and need for consultation. The response rate was 24%. Administrators appeared to underestimate mental health problems among residents. Most facilities were using at least one type of mental health service, but fewer residents received services than would be expected given the problem prevalence. Psychological services were underused, in spite of the fact that behavior management stood out as a major need. Psychiatry was more frequently used, but with less satisfaction. Results indicate significant financial and logistical barriers to mental health services. Future work is needed on developing, assessing, and disseminating models of effective service provision to long-term care.  相似文献

A patient who believed that two imposters were posing as her and her ex-fiance was diagnosed as a paranoid schizophrenic with the aid of the Rorschach, DAP and Hand Test. Projective tests not only accurately reflected various elements of the girl's psychopathology but also revealed certain voyeuristic tendencies which appeared to be related to the projection of a double. The delusion was tentatively classified as a variation of Capgras' syndrome.  相似文献

Studies have shown that dyads and groups place significantly more confidence in wrong answers to questions about a jointly witnessed event than do individuals. This experiment was designed to discover whether this misplaced confidence is influenced by prior free collaborative recall of the events in question. The results clearly indicated that prior group remembering lessens the effect, and improves the testimonial validity of both individual and group answers to questions about a jointly witnessed event. Taken in conjunction with other studies, the results imply that two or more witnesses of an event may profitably discuss what happened, but that they may best be interrogated separately in order to maximize the information available to the interrogator and to minimize misplaced confidence.  相似文献
