Five foster grandparents were taught training skills for use in their daily interactions with severely handicapped persons in an institution. Following baseline, specific teaching procedures consisting of teacher instructions, prompts, modelling, and praise were implemented. The grandparents' frequency of training three skill areas increased as the specific teaching was implemented in multiple-baseline format. The total amount of training continued as teacher instructions, prompts, and modelling were terminated and praise continued, although the grandparents spent their training time emphasizing only two of the three skill areas. Teacher presence was gradually reduced over an 11-week period, with no decrease in grandparents' frequency of training. Four of the foster grandchildren, all profoundly retarded and multiply handicapped, demonstrated progress throughout the study. Results were discussed in light of the available contributions of foster grandparents in institutional settings and maintenance of staff training.  相似文献

A thorough investigation of the literature pertaining to therapy supervision reveals that supervision has never been examined from the viewpoint of the trainee. This paper examines live supervision of family therapy from that viewpoint. It suggests that live supervision is a powerful and effective tool—a tool that engenders strong emotional responses.  相似文献

After briefly summarizing the major theoretical premises and treatment strategies of Behavioral Marriage Therapy (BMT), five major clusters of implicit assumptions in BMT are identified and critically examined: I. "The Rational Observing Ego Shall Conquer All"; II. "Behavior Should Not Mean, But Be"; III. "What's Sauce for the Goose is Sauce for the Gander"; IV. "Repression Is Good for Your Marital Mental Health"; V. "The Folly of the Therapist as Technician." Throughout this analysis, the conceptual and clinical limitations of a strictly or predominantly behavioral approach to couples therapy are described, and BMT is reconsidered in the light of object relations theory and communication theory perspectives on marital dysfunction and its treatment.  相似文献

The purpose of the present study was to determine whether the demasculinizing and feminizing effects of prenatal stress (i.e., stress applied to the mother during pregnancy) in rats reported previously are mediated by activation of the maternal pituitary-adrenal axis. Neither whole-body restraint, with or without hyperthermia, nor ACTH treatment during the last third of gestation had any reliable effect on masculine or feminine sexual behavior in male Sprague-Dawley offspring, although these treatments produced maternal pathology and evidence of maternal adrenocorticoid release. Significant littermate similarity was found for almost every morphological and behavioral measure. Failure to control for the litter variable may account for many previously reported effects of prenatal stress on sexual behavior in rats. The discrepancy between the present and earlier findings is discussed in terms of methodological and theoretical considerations.  相似文献

After surgical removal of the neocortex and hippocampal formation, rats retained most of the movement patterns of locomotion, climbing, grooming, feeding, and fighting. However, forepaw immobility during swimming was abolished. Feeding behavior was suppressed temporarily but recovered partially. The distinctive postures of sleep and walking and a circadian rhythm of motor activity were retained. However, behaviors were often not performed at the appropriate time and place. The normal sequence of grooming behavior was disrupted; food hoarding and social behavior were essentially abolished. Removal of the neocortex alone had much the same effect as removal of neocortex and hippocampus together. Removal of hippocampus alone produced only a mild disruption of behavior. It is suggested that ascending nonspecific projections to the cerebral cortex play an important role in the moment-to-moment control of behavior but are not essential for the sleep-waking cycle.  相似文献

Criteria for distinguishing between attitude and response scale effects in “after-only” studies of source-recipient discrepancy were developed and applied in two experiments. These criteria refer to congeneric scales (i.e., multiple measures of the the same property, which may differ in origin, unit, and reliability). Persuasive information may function as a scale anchor, in which case it is expected to affect only that response scale to which it directly pertains. Alternatively, it may convice recipients to change attitudinal positions, and produce effects on all congeneric scales. In one experiment, the self-proclaimed leniency-sternness of a presiding judge in a manslaughter case was varied along with the sentence he imposed and his trustworthiness. In the second study, only the sentence was manipulated, while both leniency ratings and sentencing were measured as dependent variables. Both analyses revealed support for the response scale interpretation, in that effects were observed only on those scales that were directly manipulated.  相似文献

Interpreting areas of strength and weakness on the Stanford-Binet presents problems for many clinicians. Sattler's SD method for determining normal variability provides an objective approach for dealing with this issue, and is thus a valuable tool for Binet interpretation. However, Sattler's procedure is beset by practical problems that limit its usefulness. The aim of this paper was to develop a simplification of Sattler's technique (in the form of a table) to make it easier to use and to apply to the Binet profile of any child tested. An illustration is included to demonstrate the role of the table for generating hypotheses about a child's strong and weak areas of functioning. Cautions are discussed regarding the application of the interpretive procedure.  相似文献

Reaction times of pigeons on a wavelength discrimination task   总被引:5,自引:5,他引:0       下载免费PDF全文
After extensive pretraining, three pigeons were exposed in 2-second trials to a random series of 14 light wavelengths, ranging in one nanometer (nm) steps from 575 nanometers to 589 nanometers. Responses to one of the wavelengths, 582 nanometers, were intermittently reinforced. The relative frequency of response approached 1.0 at 582 nanometers, and decreased with progressively higher and lower wavelengths. Reaction times shorter than about 0.2 second occurred with a low frequency that was largely independent of wavelength. Wavelength controlled the frequency of longer reaction times, but did not affect the distribution of these reaction times. Consequently, receiver-operating characteristic curves constructed by using reaction time as a rating measure did not conform to the signal-detection model, in contrast to such conformity when response rate is used in a similar way. The data suggest that stimulus onset as such triggers early response emission with some small probability; the probability of responses with longer latency is controlled by wavelength, but their time of emission is controlled by some independent process.  相似文献
