In this study of 37 pre-therapy and 23 matched control families who never sought family therapy, father-child welfare affect and mother-child emergency affect were significantly higher in the control families. Control families were found generally to express more Welfare and Emergency emotion. Affective expression between parents did not significantly differentiate the groups.This study has been supported by Grant No. MA-4510 of the Medical Research Council of Canada and was presented at the annual meeting of the Canadian Psychiatric Association, Ottawa, Ontario, Canada, September 1983. The authors wish to express their thanks to Toby Schwartz, Harriet Gold-Kaats, and Terry Tannenbaum-Dascal, who acted as coders and research assistants; Joseph Beltempo, BSc, who helped in the statistical analysis; and James Robbins, PhD, who gave much valuable advice.  相似文献

Various behavioral approaches to institution staff training have appeared in the literature, with some showing that traditional didactic-type instruction or tangible extrinsic reinforcement is not always necessary for effective training. The system described here used principles of modeling and feedback to teach institution staff behavior management skills. In addition, staff were assigned special titles, i.e., “case manager.” Results indicate that this individualized system was associated with improvements in the target behaviors in question, and also increased the amount of time staff properly interacted with assigned residents. Implications are with regard to using this efficient approach as a clinical tool for training staff to be effective behavioral technicians.  相似文献

This study evaluated the relative efficacy of long (1 minute) and short (15 seconds) durations of negative practice for reducing self-stimulatory leg pounding of a traumatically brain-injured adult. In individual social skill training classes, long negative practice and short negative practice were administered concurrently in an alternating treatments design. Generalization of treatment effects outside of training sessions was assessed during the client's lunch period. The results revealed that both durations of negative practice were equally effective in reducing leg pounding during training sessions. However, the effects of training did not generalize to settings in which the practice contingency was not enforced. Pounding was more frequent and negative practice somewhat less effective during periods of high social stimulation.  相似文献

A radiotelemetry system for continuous monitoring of the temperature and/or location of small animals is described. All the functions of system control are carried out by an on-line microcomputer (TRS-80 Model III), resulting in a versatile system capable of alternating recording the temperature/location of multiple subjects with other behavioral or physiological events, such as activity level. We describe the use of this system in monitoring body temperature in hamsters and in recording the incubation pattern of breeding ring doves.  相似文献

This paper reports the development and assessment of midi-level behavioral measures of social anxiety in the context of two experiments, one studying an analog student sample, the other a psychiatric sample. Judgments on nine categories of clinically practical midi-level behaviors (e.g. Facial Expression, Orienting, Sense of Timing), based on a review of the literature on human ethology and on pilot research, were compared to global judgments of social anxiety and social skill and to physiological arousal. Intraclass correlations exceeded 0.80 for judgments of the global and midi-level behavioral ratings on both samples. Results of correlational analyses indicated that while there were several significant predictors of global skill and anxiety among the midis, the magnitude of the relationship between midis and globals was stronger for the patient than the student sample. Further analyses based on S's heart rate (HR) reactivity suggested that while global ratings did not significantly predict H R in a high social anxiety situation, one midi-level behavioral rating (self-manipulations) did. The clinical utility of the newly developed measures is discussed with particular attention to their practicality for behavior therapy.  相似文献

Message therapy is a clinical procedure designed to be used as a carry-over technique with school-age stutterers or as a sole technique with the preschooler. The focus of therapy is on a unit of communication rather than on the moment or place of stuttering. One of the basic assumptions of the procedure is that the child is beginning to monitor how he/she is speaking rather than what is being communicated (i.e., the “message”)—each task requiring a different cognitive process. The emphasis of the therapy is to redirect the child's attention to “what he/she is saying.” The clinical procedures are discussed as they relate to the specific population.  相似文献

The accuracy and response latency of absolute frequency judgments were measured as a function of test lag (the number of intervening items between presentations of a test item) in a continuous memory task. Frequency was varied from one to three presentations in Experiments 1 and 2 and from one to five presentations in Experiment 3. The proportion of correct responses decreased as frequency increased, and correct mean response time tended to increase with frequency. Both accuracy and correct mean response time were found to be largely a function of the most recent test lag. The lag-latency functions were best described by piecewise linear functions, with the breakpoint occurring between lags 1 and 2. Continuous frequency estimation was also shown to improve with extended practice. The implications of the results are discussed with reference to trace strength, numerical-inference, and multiple-trace theories of frequency discrimination.  相似文献

The performance of poor and normal sixth-grade readers was compared on an auditory short-term memory task in two studies. In the first study, the effects of distraction, list length, and speed of stimulus presentation were investigated to test the hypothesis that the performance of the poor readers is affected by deficits in selective attention. Group differences in performance, however, were obtained for both distraction and no-distraction conditions. The second experiment examined the hypothesis that group differences may reflect differences in the use of rehearsal. In the second experiment, half the reading-disabled children and half the controls were provided with rehearsal training prior to completing the same short-term memory task a second time. Rehearsal training resulted in improved performance relative to children who were not trained; however, there was no rehearsal training x reading group interaction. The poor readers continued to show deficits in performance relative to the performance of control children. The results of these two studies suggest that deficits observed for poor readers on short-term memory tasks may reflect processing difficulties in some area that precedes rehearsal and affects performance under both distraction and no-distraction conditions.The authors wish to express their thanks to the Sachem School District and Betty Gould, Nicholas Opinanate, and Guy Barber for their unlimited cooperation, and to John Neale for very helpful discussions of a number of issues in this paper.  相似文献
