Two experiments investigated the effect of using a different finger for inspection (I) than is used in making judgments on the size of a kinesthetic aftereffect (KAE). Experiment I investigated transfer of I stimulation of the ring finger to judgments made with the index finger, A control group used the index finger for both judgments and 1 period. Results indicated significant KAE for both groups. Experiment II replicated Experiment I except the second finger was used to test for transfer of I stimulation to judgments made with the index finger. Results indicated KAE for only the control group which used the index finger for both judgments and 1 stimulation. 相似文献

Four experiments are reported in which the amount of CRF training prior to extinction is examined as it effects transient changes in response frequency and duration immediately following extinction onset. The first two experiments, using albino rats as subjects and water reinforcement, revealed a reliable relationship between length of time on CRF and the tendency to increase response frequency, duration, and the variability of response frequency and duration. Two comparative experiments were conducted using 53-to-69-month old children as subjects, and recorded music as reinforcement. The results of the first child study failed to conform with those obtained in the rat experiments. However, manipulation of the reinforcer in a subsequent study reproduced the rat extinction effect. Despite the differences in the rat and child experiments, the qualitative similarity of the results of the four studies suggests a basic underlying comparability of the relationship between the amount of training and transient changes in response frequency. 相似文献

When standard analogue functional analysis procedures produce inconclusive results in children with conversational speech, the child's mands may help to identify the function of destructive behavior. In the current investigation, functional analyses conducted with 2 children who exhibited self-injury, aggression, and property destruction were undifferentiated across conditions. Based on informal observations and school and parental report, an analysis was conducted using mands to help determine the function of the destructive behavior. Using a multielement design, the therapist's compliance with the child's mands occurred either on a fixed-ratio (FR) 1 schedule or contingent on destructive behavior. Destructive behavior occurred at high and consistent levels when reinforcement of mands was contingent on destructive behavior and at near-zero levels when reinforcement of mands occurred on the FR 1 schedule. Based on these results, a second analysis was conducted in which compliance to mands occurred only when the child appropriately requested it (i.e., functional communication training plus extinction) and, for 1 child, compliance with mands was terminated contingent upon destructive behavior (i.e., functional communication training plus response cost). For both children, the rates of destructive behavior decreased markedly. The results suggest that assessing the child's mands may be useful in decreasing destructive behavior when a functional analysis is inconclusive. 相似文献

In the current investigation, we used direct and indirect methods to assess and treat several topographies of aggression that were hypothesized to have separate operant functions in a young boy with severe mental retardation and pervasive developmental disorder. First, a functional analysis of aggression, using the methods described by Iwata, Dorsey, Slifer, Bauman, and Richman (1982/1994), was conducted and produced inconclusive results. Next, indirect methods were used to develop a second functional analysis, which showed that chin grinding (firmly pressing and grinding his chin against the skin and bones of others) persisted independent of social contingencies and that the other topographies of aggression (e.g., hitting, kicking) were maintained by social positive reinforcement (attention). A treatment designed to decrease aggression maintained by attention—functional communication training with extinction—reduced all forms of aggression except chin grinding. This latter topography of aggression, which we hypothesized was maintained by automatic reinforcement, was reduced when the response-reinforcer relation was interrupted through response blocking and the child was provided with an alternative form of chin stimulation. 相似文献

Transcutaneous electrical nerve stimulation is used to reduce pain but also may be useful for self-injurious behavior (SIB). In the current investigation, a microcurrent electromedical device, classified as a transcutaneous electrical nerve stimulator (TENS), was applied with a man with Down syndrome who displayed SIB that persisted in the absence of social contingencies. Although clinically significant results were not maintained, a clear difference in the rates of SIB during active and inactive TENS was observed. 相似文献

Functional communication training (FCT) is a popular treatment for problem behaviors, but its effectiveness may be compromised when the client emits the target communication response and reinforcement is either delayed or denied. In the current investigation, we trained 2 individuals to emit different communication responses to request (a) the reinforcer for destructive behavior in a given situation (e.g., contingent attention in the attention condition of a functional analysis) and (b) an alternative reinforcer (e.g., toys in the attention condition of a functional analysis). Next, we taught the participants to request each reinforcer in the presence of a different discriminative stimulus (SD). Then, we evaluated the effects of differential reinforcement of communication (DRC) using the functional and alternative reinforcers and correlated SDs, with and without extinction of destructive behavior. During all applications, DRC (in combination with SDs that signaled available reinforcers) rapidly reduced destructive behavior to low levels regardless of whether the functional reinforcer or an alternative reinforcer was available or whether reinforcement for destructive behavior was discontinued (i.e., extinction). 相似文献

Peer perceptions of relational and overt aggression and peer evaluations of social competencies were obtained for 461 boys and 443 girls in second and third grades. In contrast to Crick and Grotpeter (1995), boys obtained higher relational and overt aggression scores than girls, and the relation between both types of aggression and peer evaluations were similar for boys and girls. When controlling for levels of overt aggression, relational aggression made a statistically significant but small contribution to the prediction of both peer-evaluated competencies and teacher ratings of aggression in boys and girls. Analyses treating relational and overt aggression as categorical variables revealed gender differences in the prevalence and corresponding sociometric status of aggressive subtypes. When peer-rated relational aggression status is not considered, 60% of aggressive girls, compared to 7% of aggressive boys, are not identified as aggressive. High levels of overt aggression were more likely to result in peer rejection for girls than for boys. In a subsample of 112 children, peer-rated relational aggression contributed more to the discrimination of teacher-identified aggressive and nonaggressive girls, whereas peer-rated overt aggression contributed more to the discrimination of teacher-identified aggressive and nonaggressive boys. 相似文献
