Abstract

The aversiveness of time-out from maximal FR schedules of water reinforcement was assessed using rats as Ss. In one stimulus condition, S could produce or avoid TOs by lengthening or shortening pauses - after-reinforcement (PARs). In a second stimulus condition, Ss could similarly produce or prevent periods of stimulus change (SC). Results indicated that TO as S[triangle] or as bar retraction were equally aversive. Ss consistently shortened PARs and maintained the FR reinforcement contingencies, although no differential effects of SC conditions were observed. It was concluded that TO is aversive due to lack of reinforcement availability rather than to any effects specifically linked with extinction or cues associated with non-reinforced responding.
