In Study 1, we evaluated preference stability across 4 preference‐assessment methods for 6 individuals, 5 of whom had autism spectrum disorder and 1 of whom had traumatic brain injury. We also measured participants’ problem behavior as a corollary measure during all assessment methods. The highest mean correlation coefficients and Kendall rank coefficients of concordance across administrations were observed for the paired‐stimulus and multiple‐stimulus‐without‐replacement methods. Lower correspondence across administrations was observed for the free‐operant and response‐restriction methods. Although differentially higher levels of problem behavior did not occur with a single method, lower levels were consistently observed with the free‐operant method. During Study 2, we evaluated the implications of lower coefficients on reinforcer efficacy by comparing an initially identified and an immediately identified high‐preference stimulus in a reinforcer assessment. Initially identified and immediately identified high‐preference stimuli were equally effective reinforcers, suggesting that fluctuations in preference do not necessarily affect reinforcer efficacy in practice.  相似文献

Researchers have shown that both differential reinforcement and response cost within token economies are similarly effective for changing the behavior of individuals in a group context (e.g., Donaldson, DeLeon, Fisher, & Kahng, 2014; Iwata & Bailey, 1974). In addition, these researchers have empirically evaluated preference for these procedures. However, few previous studies have evaluated the individual effects of these procedures both in group contexts and in the absence of peers. Therefore, we replicated and extended previous research by determining the individual effects and preferences of differential reinforcement and response cost under both group and individualized conditions. Results demonstrated that the procedures were equally effective for increasing on‐task behavior during group and individual instruction for most children, and preference varied across participants. In addition, results were consistent across participants who experienced the procedures in group and individualized settings.  相似文献

We evaluated rates of automatically reinforced stereotypy and item engagement for 2 children with autism under multiple and chained schedules in a multielement design. Each schedule included components during which stereotypy was blocked (S–) or allowed (S+), and we used colored cards as schedule‐correlated stimuli. We report rates of stereotypy and item engagement during S– and S+ components, as well as the percentage of component time that elapsed before the first instances of stereotypy and item engagement. We observed less stereotypy and more consistent item engagement during chained‐schedule sessions, and stimulus control of stereotypy and item engagement was established with the chained schedule. A subsequent concurrent‐chains analysis revealed participant preference for the chained schedule. These results highlight the importance of contingent access to stereotypy when therapists attempt to gain stimulus control of stereotypy and increase functional item engagement.  相似文献

Pigeons and other animals sometimes deviate from optimal choice behavior when given informative signals for delayed outcomes. For example, when pigeons are given a choice between an alternative that always leads to food after a delay and an alternative that leads to food only half of the time after a delay, preference changes dramatically depending on whether the stimuli during the delays are correlated with (signal) the outcomes or not. With signaled outcomes, pigeons show a much greater preference for the suboptimal alternative than with unsignaled outcomes. Key variables and research findings related to this phenomenon are reviewed, including the effects of durations of the choice and delay periods, probability of reinforcement, and gaps in the signal. We interpret the available evidence as reflecting a preference induced by signals for good news in a context of uncertainty. Other explanations are briefly summarized and compared.  相似文献

In a cross‐sectional sample of African‐American 2nd–4th grade students (N = 681), we examine the moderating effects of classroom overt and relational aggression norms on peers’ social acceptance of classmates who exhibit overt and relational aggression in urban schools. Extending theory and research on classroom norms, we integrate social network data to adjust aggression norms based on children’s direct and indirect connections in the classroom. Results of multilevel models indicate that network‐based classroom aggression norms moderated relations between children’s aggressive behavior and their social preference. Specifically, children benefited socially when their form of aggressive behavior fit with what was normative in the classroom social context. The moderating effect of classroom aggression norms was stronger for the association between overt aggression and social preference than relational aggression and social preference. Relationally aggressive youth were socially preferred by peers regardless of the classroom norm, although this positive association was magnified in classrooms with higher levels of relational aggression. Future research focused on aggression norms within classroom social networks are discussed and implications for school prevention efforts are considered.  相似文献
