Five parents of nonverbal children were trained in two home settings to modify antecedents and consequences to their children's vocalizations. Generalization effects of the parent training on both the parent's and children's behaviors under different stimulus conditions were investigated using multiple-baseline designs. Increases in parent prompting and reinforcing their children's vocalizations generalized only minimally to a new setting in the home where parent training had not occurred. Child increases in vocalizations produced by the parents in the training settings did generalize to this new setting in the home. There was minimal generalization of child vocalizations to a free-play setting at school. In a formal speech session conducted by a behavior specialist at school, only one child showed definite increases in acquisition rate as a function of the parents starting to train the sound at home. 相似文献

One of the major goals of prisons has been the educational rehabilitation of inmates. Studies have shown that predelinquents as well as delinquents could be motivated to achieve in academic areas through the use of an incentive system. The present study attempted to extend the behavioral yield of such a system with prison inmates. The academic performance of two inmates in math and English were compared when two levels of incentives were made contingent on that performance. The results showed that the two inmates passed academic tests as much as nine times faster under an enriched schedule of incentives than under a standard one. This increase in rate of performance was translated into actual academic achievement as one of the inmates passed 9th through 12th grade algebra in only 14 days. A standardized test confirmed this academic advancement for both inmates. These high rates of performance and academic achievement are even more dramatic in view of the fact that five months prior to this procedure, both inmates had been tested as being below average in intelligence. 相似文献

Verbal rehearsal and selective attention in children with learning disabilities: A developmental lag
Sara G Tarver Daniel P Hallahan James M Kauffman Donald W Ball 《Journal of experimental child psychology》1976,22(3):375-385
To investigate the development of verbal rehearsal strategies and selective attention in learning disabled children, Hagen's Central-Incidental task was administered to younger learning disabled (M CA = 8.68 years) and normal (M CA = 8.62 years) boys in Experiment 1 and to intermediate (M CA = 10.18 years) and older (M CA = 13.48 years) learning disabled boys in Experiment 2. Also, in Experiment 2, an experimentally induced verbal rehearsal condition was included to determine its effects on serial recall and selective attention performance. In Experiment 1, the serial postion curve of the normals revealed both a primacy and a recency effect, whereas that of the learning disabled revealed a recency effect only. In Experiment 2, both the intermediate and the older learning disabled exhibited both primacy and recency effects under both standard and rehearsal conditions. A developmental analysis of central recall for the three learning disabled groups revealed constant age-related increases in overall central recall and in primacy recall. That the normals recalled more central, but not more incidental, information than the learning disabled in Experiment 1 suggests that the learning disabled are deficient in selective attention. Correlational findings suggest that the selective attention of the learning disabled improves with age. The results were interpreted as support for the hypothesis of a developmental lag in the learning disabled population. 相似文献

The associations formed in the components of a multiple schedule can be classified as (1) stimulus-response (S-R) associations and (2) stimulus-reinforcer (S-SR) associations. The present experiments sought to determine the individual contribution of these S-R and S-SR associations to stimulus control by manipulating them independently. Responses postponed shocks by 25 sec in the presence of a tone alone and a light alone in all experiments. The contingencies programmed in the absence of both tone and light established a reference for the S-R and S-SR associations in tone and in light. All four possible combinations of signalling response increase or decrease together with incentive increase or decrease were studied. Although the influence of the contingencies operating in the absence of tone and light was difficult to detect from response rates in tone or light, presenting tone and light together revealed clear effects. Response rates in tone and light together relative to those in either alone depended upon the contingency operating in the absence of tone and light. Stimulus-response and stimulus-reinforcer associations appeared to counteract each other when in opposition and combine together to enhance each other when in agreement. This suggested that the associations of a stimulus to response and to incentive combine algebraically in determining stimulus control. An algebraic analysis in terms of the S-R and S-SR associations conditioned to the stimulus elements comprising the training and test stimuli accounted for the observed patterns of data. 相似文献

In two experiments with paired rats, the effect of superimposing CS-US pairings on a baseline of shock-elicited aggression was studied. Baseline shocks (3.0 mA, 0.125-sec duration) occurred at a rate of 20 shocks per min throughout each session. In Experiment I, each independent group of two pairs of subjects received (in addition to baseline shocks) US shocks of 1.0, 3.0, or 5.0 mA and 5-sec duration, each shock signalled by a 1-min CS. At all three US intensities, aggression increased during the CS. In Experiment II, pairs of subjects received each unconditioned stimulus intensity in a within-subjects design. This procedure revealed a direct relationship between rate of responding and unconditioned shock intensity. 相似文献

In two experiments, rats received noncontingent pairings of two stimuli with food reward, one paired with small reward and the other with large reward, and received bar press training with large reward or with small reward. When the noncontingent stimuli (NS) were presented for test during subsequent rewarded bar pressing and during early extinction of bar pressing, responding for each group was faster in the presence of the NS which was paired with the same reward magnitude that group received in bar press training than to the NS which had been paired with a different reward magnitude. As extinction progressed, all groups responded more slowly in the presence of the NS which had been paired with the large reward than in the presence of the NS which had been paired with small reward. These results were interpreted as indicating that responding in the presence of an NS depends on: (i) whether the reward expectancy elicited by the NS has been conditioned to the instrumental response, and (ii) the relationship between the reward expected in the presence of the NS and that received in test. 相似文献

This study systematically investigated the effects of different procedures on classroom behaviors ranging from teacher designated seating groups and seating groups based on sociometric data to peer encouragement and free time reinforcers. Subjects were first- and third-grade children in classrooms using a Follow Through program model. Data were taken on the attending behavior of the children in small groups arranged by the teacher. The level of appropriate attending behavior was low and did not increase when the groups were restructured based on sociometric data. The introduction of instructions to the peer groups to help the child with his or her work brought about a major increase in the third-grade subjects' appropriate behavior. Appropriate attending behavior for the first-grade children did not increase to the predetermined acceptable level until a free time period for each peer group was made contingent upon the appropriate behavior of the subject in each group. Frequencies of verbal interactions suggested peer attention has an effect on the appropriateness of peer interactions. 相似文献

Disruptive behavior in young children is one of the most common referrals to behavioral health providers. While numerous effective parenting programs, such as parent–child interaction therapy (PCIT), exist for improving children’s behaviors, challenges with treatment engagement and retention limit the intended positive impact on child and caregiver outcomes, particularly for racial and ethnic minority families. In an effort to address barriers contributing to poor engagement and retention in traditional PCIT service delivery and among ethnic and racial minority families, a multimedia PCIT ebook was developed and evaluated. In a sample of the general public that utilized the ebook, users were found to be more engaged in viewing embedded videos within the ebook that were related to expert skill explanations and skill demonstrations than caregiver testimonies. A randomized controlled trial was also conducted to evaluate the extent that the ebook + PCIT improved treatment engagement, retention, parenting skills, skill acquisition efficiency, and child behavior above and beyond traditional PCIT. Participating families were randomly assigned to either the traditional PCIT (n = 71) or ebook + PCIT (n = 107) group using an online random number generator. Forty-nine caregivers (traditional PCIT n = 24, ebook + PCIT n = 25) were excluded from analyses because they were lost to follow-up during the intervention. Families in both the traditional PCIT and ebook + PCIT groups demonstrated generally equivalent positive outcomes in treatment engagement (i.e., attendance, treatment length, completion rate) and caregiver skill acquisition efficiency at midtreatment, posttreatment, and 3-month follow-up. The addition of the ebook to PCIT also reduced child disruptive behavior at midtreatment, above and beyond traditional PCIT, but not at posttreatment or follow-up. Clinical implications and future directions are discussed. 相似文献

The SARS-COV-2 (COVID-19) pandemic and associated social distancing guidelines have accelerated the telehealth transition in mental health. For those providing Behavioral Parent Training (BPT), this transition has called for moving sessions that are traditionally clinic-based, active, and directive to engaging, supporting, and treating families of children with behavior disorders remotely in their homes. Whereas many difficulties accompany this transition, the lessons learned during the current public health crisis have the potential to transform BPT service delivery on a large scale in ways that address many of its long-standing limitations. We describe both challenges and opportunities and consider the possibilities inherent in a large scale BPT service delivery model capable of increasing the reach and impact of evidence-based treatment for all families. 相似文献
