Abstract
Trained 4 groups of 15 Long-Evans hooded rats on 2 2-choice discrimination problems under a shock-avoidance shock-avoidance or a shock-avoidance food-approach motivational sequence. The ECS or sham-ECS treatments were delivered as Ss attained criterion on the 2nd habit. Retention tests for the 1st habit showed no motivational-specific ECS effects, but motivationally related retroactive interference was found. The amount of this interference with retention proved to be much larger than has previously been obtained with 3-habit training paradigms.
