The choice-making behavior of 2 typically developing children who engaged in problem behavior maintained by negative reinforcement was evaluated within a concurrent-operants assessment that varied the quality of attention across free-play and demand conditions. The results demonstrated that it was possible to bias responding towards academic…

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…

Previous outcome studies have provided descriptions of functional analyses conducted in outpatient clinics (Derby et al., 1992), long-term inpatient programs (Iwata, Pace, et al., 1994), and home environments (Wacker et al., 1998). This study provides a description of 138 children and adults with and without developmental disabilities who were…

Two case examples (a toddler with severe developmental delays and a 7-year old with severe mental retardation) illustrating effects of meal schedule and food quantity on displays of problematic behavior are offered. Brief functional analyses of aberrant behavior provided useful information for interpreting distinct patterns of behavior. (DB)

A study examined the effects of a high-probability procedure on the compliance with medical procedures of a toddler with developmental delays and self-injurious behavior. Compliance to low-probability requests occurred more frequently following compliance to high-probability requests, suggesting that this procedure may be useful across different…

Pretreatment assessment data were used to enhance an existing treatment package to reduce aggression and to increase the positive social interactions of a 9-year-old boy with moderate mental retardation and Hunter's syndrome. Additional reinforcements and punishment components were added and resulted in positive social interactions and suppressed…

The effects of a presession exposure to attention on responding during subsequent assessment of attention as a reinforcer were evaluated across three behavioral assessments. In each experiment, the children responded differentially within the test condition according to the presence or absence of dense schedule of attention immediately prior to…
