Amphetamine can increase conditioning to poor predictors of reinforcement in selective learning tasks (e.g. latent inhibition, LI). In the present study, a noise stimulus was contiguous with footshock or presented at a trace interval. A flashing light background stimulus was used to measure contextual conditioning. Experiment 1 used 1.5 mg/kg and 6 mg/kg dl-amphetamine. Experiments 2 and 3 used 0.5 mg/kg and 1.5 mg/kg d-amphetamine. Unconditioned stimuli parameters (intensity, number, duration… CONTINUE READING
