RESUMO

We evaluated the usefulness of 2 assessments to guide treatment selection for individuals whose prior functional analysis indicated that automatic reinforcement maintained their problem behavior. In the 1st assessment, we compared levels of problem behavior during a noncontingent play condition and an alone or ignore condition. In the 2nd, we assessed participants' relative preferences for automatic reinforcement and social reinforcers in a concurrent-operants arrangement. We used the results of these 2 assessments to assign 5 participants to a treatment based on noncontingent access to social reinforcers or to a treatment based on differential access to social reinforcers. We conducted monthly probes with the participants over 10 to 12 months to evaluate the effects of the treatment procedures. All participants showed reductions in problem behavior over this period.

RESUMO

We conducted a three-phase study to evaluate the use of mands and the occurrence of problem behavior for 2 children with developmental disabilities. During Phase 1, a functional analysis identified the variables maintaining problem behavior. During Phase 2, functional communication training was implemented within a concurrent schedules design. The children were reinforced for using either a novel mand (communication card) or other existing mands (vocal speech, manual signs) that were not specifically trained but were observed to be part of the children's existing repertoire. We then conducted an assessment of mands and problem behavior across different stimulus conditions (card absent, card present) within an ABAB design (Phase 3). Results showed that during Phase 2, problem behavior decreased and participants used the card more frequently than they used other existing mands. Phase 3 showed that problem behavior remained low across both stimulus conditions. When the card was absent, the children used other existing mands; when the card was present, they primarily used the card. These results suggested that the presence of a communication card may function as a discriminative stimulus for a specific topography of manding, but that training with the card did not inhibit the use of other mands when the card was absent.

RESUMO

Preference for mand topography was evaluated for 2 individuals with developmental disabilities who exhibited problem behavior. The results of a functional analysis showed that each participant's problem behavior was maintained by social reinforcement. Participants were taught two novel mand topographies for the same functional reinforcer, and each proved to be effective in reducing problem behavior. Finally, preference for mand topography was assessed within a concurrent-schedules design. Results indicated that functional communication training was an effective treatment, regardless of the mand used, and that each participant demonstrated a preference for one mand topography relative to the other.

RESUMO

We evaluated the effects of reinforcing multiple manding topographies during functional communication training (FCT) to decrease problem behavior for three preschool-age children. During Phase 1, a functional analysis identified conditions that maintained problem behavior for each child. During Phase 2, the children's parents taught them to request positive reinforcers (attention or toys) via vocal manding, manual signing, or touching a picture/word card with or without a microswitch recording device. A non-concurrent multiple-baseline design across children was used to evaluate FCT outcomes. Results showed that problem behavior decreased for all three children. Results also indicated that the children initially used multiple manding topographies but displayed a preference for vocal manding over time.
