Parallel Group

Under relational conditions with electric shock punishment for incorrect responses, all 9 rats learned to choose the dimmer of two stimuli; no Ss in a parallel group of rats ( N = 6) given equivalent training under absolute conditions reached the learning criterion. Results are interpreted as supporting the Gestalt theory of discrimination learning rather than the theory of Spence.

Reliable Difference

Caimans were trained to escape shock in a T-maze with either brightness cues or confounded brightness and spatial cues relevant. After criterion was reached on the confounded problem, the positions of the brightness cues were then varied for these Ss with position becoming an irrelevant cue and the color of the positive cue unchanged. Although the confounded problem was learned more quickly than the brightness problem, there was no statistically reliable difference in the over-all training required to learn the brightness problem regardless of prior training on the confounded task.
