Operant Stimulus Control Applied to Maze Behavior: II. Positive Reinforcement of Discrimination Reversal in Rats

Abstract

4 rats were reinforced with cream and sugar for traversing a 4-ft. runway which allowed right and left approaches to separate goal boxes. After each S had satisfied 3 criteria of stable responses to a goal, the path to that goal was blocked by a door, thus requiring a discrimination reversal. All Ss met the same criteria of stability through 2 to 4 reversals as a decreasing function of number of reinforced trials.
