Evaluating the role of contingency in differentially reinforced tic suppression.
Journal of Applied Behavior Analysis, 2008,
41, 285-289.
The current study evaluated the effects of tokens delivered on differential
reinforcement of zero-rate behavior (DRO) schedules or noncontingently
on tic suppression in 4 children with tics. Tic frequency was lower in 3 of
4 children when tokens were delivered contingent on the absence of tics
than when tokens were delivered noncontingently.
DESCRIPTORS: differential reinforcement of other behavior, noncontingent reinforcement, suppression, tic disorder, tokens, Tourette syndrome
