Abstract
The performance of pigeons and goldfish was studied in a series of discrete-trial red-green discrimination reversals, with stimuli presented singly and the time of response to each measured. Both animals showed progressive improvement, but it took different forms. In the pigeons, there was a decline over reversals in the temporal stability of inhibition and an increase in the rate of inhibitory development. In the goldfish, there was a general increase in speed of response to the positive stimulus. The results are compared with those obtained in previous experiments.
