48 Wistar rats were submitted to a continuous reinforcement schedule in a Skinner box. During acquisition or re- acquisition, rats reached the same learning criterion fixed at 10 rounds trips between the lever and the food dish with manipulation of the bar. The re-acquisition phase occurred 15 days after the acquisition phase. The number of experimental sessions during acquisition or re- acquisition varied according to the animals. We analysed precisely the behaviour of rats with a descriptive grid of 34 different behavioural patterns grouped in 4 categories based on the location of the bahaviour in the apparatus. The rats' behaviour was continuously video-taped. We show that the rats used a selective memory according to the location in the Skinner box and the nature of the behaviour.
