Avoidance disruptive effect of clozapine and olanzapine is potentiated by increasing the test trials: Further test of the motivational salience hypothesis

► Repeated clozapine and olanzapine treatment persistently decreased avoidance response in rats. ► Their avoidance disruptive effect was potentiated by the increase of number of test trials. ► The potentiation was also observed in the within-session avoidance responding decline pattern.
