This study examined the effects of presession exposure to attention, response blocking, attention with response blocking, and noninteraction conditions on subsequent engagement in automatically maintained challenging behavior and correct responding in four individuals with significant intellectual disabilities. Following a functional analysis, the…

Chronic tic disorders, including Tourette's syndrome (TS), affect approximately .5% of children and adolescents. Although strong evidence exists supporting a neurobiological etiology, operant factors may play a role in the maintenance of tic behaviors.

The authors assessed new microswitch clusters (i.e., combinations of two microswitches) and contingent stimulation to increase adaptive responses (i.e., foot and head movements) and reduce aberrant behavior (i.e., finger mouthing) in a boy with multiple disabilities. Initially, intervention was directed at increasing the frequency of each adaptive…

Indices of happiness and unhappiness were defined, and a corresponding observation system was developed and implemented with five students in an adult education classroom. Results indicate the definitions and the observation system reliably identified frequencies of happiness and/or unhappiness indices for each student across separate activities.…
