This study asked whether behavioral variability is influenced by the previous reinforcement experience. Ratswere exposed to schedules of reinforcement for sequences of four bar-press responses (right bar -R and left bar -L). In the CRFschedule, every sequence was reinforced. In the other schedules, reinforcement was intermittent, being contingent upon sequencevariation (VAR) or independent of it (ACO). Variability was measured by the distribution of R or L responses withinthe sequence. Half of the animals were exposed to the order CRF-VAR-CRF-ACO-CRF-VAR (group I) and half to CRFACO-CRF-VAR-CRF-ACO (group II). All subjects showed the highest variability under VAR. During CRF and ACO contingencies,no variability was observed if these conting...
