Description
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.
