RESUMEN

We conducted functional analyses of aberrant behavior with 4 children with developmental disabilities. We then implemented functional communication training (FCT) by using different mands across two contexts, one in which the establishing operation (EO) that was relevant to the function of aberrant behavior was present and one in which the EO that was relevant to the function of aberrant behavior was absent. The mand used in the EO-present context served the same function as aberrant behavior, and the mand used in the EO-absent context served a different function than the one identified via the functional analysis. In addition, a free-play (control) condition was conducted for all children. Increases in relevant manding were observed in the EO-present context for 3 of the 4 participants. Decreases in aberrant behavior were achieved by the end of the treatment analysis for all 4 participants. Irrelevant mands were rarely observed in the EO-absent context for 3 of the 4 participants. Evaluating the effectiveness of FCT across different contexts allowed a further analysis of manding when the establishing operations were present or absent. The contributions of this study to the understanding of functional equivalence are also discussed.

RESUMEN

The authors evaluated the responsiveness of 4 preschool-aged children to positive reinforcers within a concurrent operants paradigm during mealtimes. The children were presented with two identical, concurrently available sets of food. Each set differed in quantity and quality of positive reinforcement paired with acceptance of each bite of food or in the number of bites of food required to obtain positive reinforcement. Experiment 1 evaluated 1 child's responsiveness to positive reinforcement while permitting escape from bite offers. Experiment 2 evaluated 2 children's responsiveness to positive reinforcement when escape extinction occurred. Results from these experiments suggested that the children were responsive to positive reinforcers and chose more often the bites paired with the greater quantity and/or quality of reinforcement. Experiment 3 evaluated 1 child's responsiveness to positive reinforcement both without and with escape extinction. Results suggested that positive reinforcement affected choice behavior and that escape extinction affected amount of food consumed.

RESUMEN

Multiple sleep problems of a 2-year-old girl improved following treatment with a faded bedtime with response cost procedure (Piazza & Fisher, 1991). These results extend the literature by implementing treatment in a home setting with a nondisabled child using the parents as therapists.

RESUMEN

Every community has children placed in the out-of-home care system. Despite a high prevalence of health, mental health, and developmental morbidity in children in care, most child welfare agencies have not provided adequate diagnostic and therapeutic services for these children. A comprehensive, multidisciplinary clinic for children in out-of-home care involving pediatrics, child psychology, nursing, child development, and child welfare is described. Profiles of the health, mental health, and developmental status of the children in out-of-home care are also presented.

RESUMEN

The choice-making behavior of 5 young children with developmental disabilities who engaged in aberrant behavior was studied within a concurrent operants framework. Experimental analyses were conducted to identify reinforcers that maintained aberrant behavior, and functional communication training packages were implemented to teach the participants to gain reinforcement using mands. Next, a choice-making analysis, in which the participants chose one of two responses (either a mand or an alternative neutral response) to obtain different durations and qualities of reinforcement, was conducted. Finally, treatment packages involving choice making via manding were implemented to decrease inappropriate behavior and to increase mands. The results extended previous applications of choice making to severe behavior disorders and across behaviors maintained by positive and negative reinforcement.

RESUMEN

We evaluated the separate components in treatment packages for food refusal of 4 young children. First, treatment packages were implemented until food acceptance improved. Next, a component analysis was conducted within a multielement or reversal design to identify the active components that facilitated food acceptance. The results indicated that escape extinction was always identified as an active variable when assessed; however, other variables, including positive reinforcement and noncontingent play, were also identified as active variables for 2 of the children. The results suggest that the component analysis was useful for identifying variables that affected food acceptance.
