Discrimination Reversal

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.

Supplementary Report

Spatial discrimination reversal learning was explored for mice genetically selected for high brain weight and unselected controls with lower brain weights. Control-line Ss escaped from a water maze more rapidly, but high-line Ss made fewer errors and took less trials to reach criterion on the first reversal. Control-line Ss were unable to complete more than 1 reversal, while high-line Ss all completed at least 7 reversals. This positive relation between reversal learning and brain size is consistent with comparisons among species and experiments manipulating brain size by means of drugs or surgery.
