Abstract
Pigeons were trained on a discrimination using the “errorless” procedure devised by Terrace and then given a discrimination reversal Their extinction to the previously positive cue during reversal was similar to a control group given continuous reinforcement during original training. Most of the Ss in the errorless group, however, failed to learn the reversal because they did not respond to the previously negative cue during five days of reversal training.
