Effect of Duration of Reinstatement on Retention of A Visual Discrimination Learned in Infancy

Byron A. Campbell and Julian Jaynes
Developmental Psychology, 1969, 1 (2): 71-74.


One hundred sixty weaning rats were trained on a light-dark discrimination and then given one reinstatement per week for ten weeks. They were then tested for retention of the original discrimination. Five different durations of reinstatement were used: 0, 7.5, 15, 30, and 60 min. The longer the weekly reinstatement, the better the retention of the discrimination when tested either by relearning or resistance to extinction.
