We used procedures based on response-restriction (RR) analysis to assess vocational and leisure activity preferences for 3 adults with developmental disabilities. To increase the efficiency of the analysis relative to that reported in previous research, we used criteria that allowed activities to be restricted at the earliest point at which a preference could be determined. Results obtained across two consecutive RR assessments showed some variability in overall preference rankings but a high degree of consistency for highly ranked items. Finally, we compared results of the RR assessment with those of an extended free-operant assessment and found that the RR assessment yielded (a) more differentiated patterns of preference and (b) more complete information about engagement with all of the target activities. 相似文献

We evaluated the effects of response cards on student quiz scores and participation in an upper division undergraduate course at a small, private university. Results showed that response cards increased both quiz scores and student participation. In addition, a measure of the social validity of the response-card procedure suggested that students approved of the use of the cards. 相似文献

This study investigated students' allocation of responding as a function of task difficulty and type of reinforcement contingency (i.e., accuracy based or time based). Four regular education fourth-grade students were presented with two identical stacks of easy and then difficult math worksheets using a reversal design. Regardless of condition, completing problems from each stack of worksheets was reinforced according to a different contingency; one required correct completion of math problems (accuracy based) and one required on-task behavior (time based). Results suggested that 3 of the 4 students preferred the accuracy-based contingency when given easy material and the time-based contingency when given difficult material. One student allocated more responding to the accuracy-based contingency when given easy problems but did not show a clear preference for either contingency with difficult problems. The implications of these findings for designing reinforcement-based programs for tasks of varying difficulty are discussed. 相似文献

Placebo effects contribute to beneficial therapeutic responses and are common in anxiety and depressive disorders. It is posited that placebo effects are yielded by autonomous feeling-toned complexes capable of re-establishing background self-states of well-being. The relationship between the placebo response complex and modern neurobiological models of self is explored. The psychological roots of the placebo response complex in implicit memories of organized attachment between child and early caretakers and in Sandler's conception of the benign superego are examined. The relationships between the negative placebo (nocebo) response complex, Freud's negative therapeutic reaction, and Fordham's defence of the self are explored. Finally, it is suggested that approaches fundamental to the analytic encounter, e.g., mirroring, affectual exchanges, attunement, and containment are likely to optimize the salutary effects of both psychological and somatic therapeutic interventions. 相似文献

A common deficiency in the verbal repertoires of individuals with autism and related disorders is the absence of socially appropriate vocal mands. The vocal mand repertoires of these individuals may be lacking in several respects: (a) The individual might engage in no mands whatsoever, (b) the mand might be topographically dissimilar to an appropriate response, (c) the mand might be only partially topographically similar to an appropriate response, and (d) the mand might occur only after prompting. Depending on specific deficiencies in an individual's repertoire, different procedures for establishing appropriate mands may be needed. The purpose of Study 1 was to evaluate an assessment prior to teaching vocal mands for 3 individuals with developmental disabilities. The assessment showed that 1 individual displayed partial utterances of mands, 1 displayed vocal mands after mands had been reinforced, and 1 displayed vocal mands when prompted. Thus, in Study 2, a different teaching strategy was tested for each individual. Results showed that the assessment information could be linked directly to mand training for all 3 participants. 相似文献

We replicated a method for clarifying inconclusive functional analysis outcomes via an extinction analysis of separate topographies of problem behavior with 2 participants. Results suggested that both mild and severe problem behaviors belonged to the same response class. An analysis of response latency was consistent with a response class hierarchy hypothesis, indicating that mild problem behavior nearly always occurred prior to severe topographies of problem behavior. 相似文献

Twelve pigeons responded on two keys under concurrent variable-interval (VI) schedules. Over several series of conditions, relative and absolute magnitudes of reinforcement were varied. Within each series, relative rate of reinforcement was varied and sensitivity of behavior ratios to reinforcer-rate ratios was assessed. When responding at both alternatives was maintained by equal-sized small reinforcers, sensitivity to variation in reinforcer-rate ratios was the same as when large reinforcers were used. This result was observed when the overall rate of reinforcement was constant over conditions, and also in another series of concurrent schedules in which one schedule was kept constant at VI ached 120 s. Similarly, reinforcer magnitude did not affect the rate at which response allocation approached asymptote within a condition. When reinforcer magnitudes differred between the two responses and reinforcer-rate ratios were varied, sensitivity of behavior allocation was unaffected although response bias favored the schedule that arranged the larger reinforcers. Analysis of absolute response rates ratio sensitivity to reinforcement occurrred on the two keys showed that this invariance of response despite changes in reinforcement interaction that were observed in absolute response rates on the constant VI 120-s schedule. Response rate on the constant VI 120-s schedule was inversely related to reinforcer rate on the varied key and the strength of this relation depended on the relative magnitude of reinforcers arranged on varied key. Independence of sensitivity to reinforcer-rate ratios from relative and absolute reinforcer magnitude is consistent with the relativity and independence assumtions of the matching law. 相似文献

Non‐suicidal self‐injury (NSSI) is an increasing health concern. Despite the potential benefits of disclosing the behaviour, many decide not to do so because of the fear of negative social reactions. In this review, we examined the existing research on reported and perceived reactions to NSSI disclosure with the aim of identifying how an individual who discloses their NSSI perceives others' responses to this disclosure, with the ultimate goal of understanding how these reactions may impact those who disclose their NSSI. Among the initial 275 studies, 10 fit the inclusion criteria. Three studies reported perceived responses by individuals who had disclosed their NSSI; six studies examined self‐reported responses by others; one study focused on disclosures online. Individuals who disclosed their NSSI often received negative responses, which caused them to withdraw from seeking further help. On the other hand, recipients' reactions to NSSI disclosure varied based on NSSI characteristics such as its perceived cause and/or underlying motivation. Results highlight the importance of providing support rather than searching for the underlying drives of NSSI. 相似文献

Concurrent schedules: How responses per reinforcer affects estimates of sensitivity to reinforcement
Michael Davison 《Journal of the experimental analysis of behavior》2021,116(1):114-123
Conventionally, when choice is measured under concurrent schedules, all responses are included. However, the class of all responses consists of 2 sub-classes which are discriminable by their properties: Reinforced responses always equal obtained reinforcers, while unreinforced responses are free to vary. As a result, the inclusion of reinforced responses in choice measures results in sensitivity values in generalized matching that are biased toward larger values, and this bias becomes extreme in some combinations of overall response and reinforcer rates. Different ways of varying concurrent-schedule values also affect estimated sensitivity and the linearity between choice based on all responses and reinforcer ratios. To avoid spurious results and comparisons, and as a matter of good practice, generalized-matching fits and measures should be done using only unreinforced responses. 相似文献
