Preference for progressive delays and concurrent physical
therapy exercise in an adult with acquired brain injury.
Journal of Applied Behavior Analysis,
37, 101-105.
The purpose of this study
was to increase self-control and engagement in a physical therapy task (head holding) for a man with
acquired traumatic brain injury. Once impulsivity was observed (i.e., repeated impulsive choices), an
experimental condition was introduced that consisted of choices between a small immediate
reinforcer, a large fixed-delay reinforcer, and a large progressive-delay reinforcer. The participant
showed a preference for the progressive-delay option, even when the duration of the delay exceeded
that of the fixed delay. The results have implications for establishing optimal choice making and
teaching life-enhancing skills.
