Reinforcement techniques of prompting and shaping were employed to develop hand-waving, a useful social greeting response, in four institutionalized retarded subjects. A multiple-baseline design across subjects demonstrated the reliable functioning of the training procedures. Specifically, it showed that training and maintenance of the greeting response by one experimenter was not usually sufficient for generalization of the response to the more than 20 other members of the institution staff who had not participated in the training of the response. However, high levels of generalization to staff members were recorded for three subjects over periods ranging from one to six months after a second experimenter trained and maintained the response in conjunction with the first experimenter. The fourth subject, although never receiving training by a second experimenter, showed similar results following a second training by the first experimenter. 相似文献

A correspondence training procedure was used to develop consistency between children's verbalizations and their subsequent behavior across increasingly remote settings and time. The interval of time between the verbalizations and the opportunity to engage in several target behaviors was systematically increased across four preschool settings. Probes of generalized verbal control of home behaviors were conducted throughout training and showed that generalization was obtained in the absence of any salient externally imposed contingencies after the children had reliably come under the control of verbalizations about preschool behaviors. 相似文献

Research shows that behavioral skills training (BST) and in situ training (IST) are effective interventions for teaching safety skills to children. In addition, the efficiency of these interventions can be increased when parents, teachers, or peers are taught to implement them. The purpose of this study was to replicate Novotny et al. (2020) and evaluate a web-based program for teaching parents to conduct BST to teach safety skills to prevent gunplay. We randomly assigned 18 children to the parent-conducted BST group or a control group and evaluated the intervention in a posttest only control group design. Children in the control group or treatment group who did not score a three in the in situ assessment (do not touch, get away, and tell an adult) received IST from their parents and were assessed again. Results showed that safety skill scores were statistically significantly higher in the treatment group than in the control group. Furthermore, there was a statistically significant increase in safety skills scores following IST for children who received it. 相似文献

Synaptically released Zn2+ is a potential modulator of neurotransmission and synaptic plasticity in fear-conditioning pathways. Zinc transporter 3 (ZnT3) knock-out (KO) mice are well suited to test the role of zinc in learned fear, because ZnT3 is colocalized with synaptic zinc, responsible for its transport to synaptic vesicles, highly enriched in the amygdala-associated neural circuitry, and ZnT3 KO mice lack Zn2+ in synaptic vesicles. However, earlier work reported no deficiency in fear memory in ZnT3 KO mice, which is surprising based on the effects of Zn2+ on amygdala synaptic plasticity. We therefore reexamined ZnT3 KO mice in various tasks for learned and innate fear. The mutants were deficient in a weak fear-conditioning protocol using single tone-shock pairing but showed normal memory when a stronger, five-pairing protocol was used. ZnT3 KO mice were deficient in memory when a tone was presented as complex auditory information in a discontinuous fashion. Moreover, ZnT3 KO mice showed abnormality in trace fear conditioning and in fear extinction. By contrast, ZnT3 KO mice had normal anxiety. Thus, ZnT3 is involved in associative fear memory and extinction, but not in innate fear, consistent with the role of synaptic zinc in amygdala synaptic plasticity. 相似文献

Excessive pain during medical procedures, such as burn wound dressing changes, is a widespread medical problem and is especially challenging for children. This article describes the rationale behind virtual reality (VR) pain distraction, a new non-pharmacologic adjunctive analgesia, and gives a brief summary of empirical studies exploring whether VR reduces clinical procedural pain. Results indicate that patients using VR during painful medical procedures report large reductions in subjective pain. A neuroimaging study measuring the neural correlates of VR analgesia is described in detail. This functional magnetic resonance imaging pain study in healthy volunteers shows that the large drops in subjective pain ratings during VR are accompanied by large drops in pain-related brain activity. Together the clinical and laboratory studies provide converging evidence that VR distraction is a promising new non-pharmacologic pain control technique. 相似文献
