Following a reversal, when overall reinforcement is equivalent, the predictive lever stimulus can bias preference. Mean (±SEM) percent choice of the predictive alternative (lever n = 6; light n = 6) during a reversal. (B) Mean response rates for sign- and goal-tracking responding during the absence of the predictive stimulus during the last four sessions of reversal training.
