Effect of prior patterns of experience upon strategies and learning sets.

Abstract
Undergraduate subjects were required to learn that a simple and regular pattern of payoff held on a 2-choice gambling device. Before this pattern was introduced, subjects were given varying experience of other arrangements of payoff, both regular and irregular. Learning of the final regular pattern was facilitated by prior experience with other regular patterns, not necessarily the same as the final one, even when the earlier pattern experience was separated from the final pattern by 70 trials of random payoff. The results are explained in terms of the way prior experience establishes and maintains a consistent mode of response or "strategy" which facilitates observation of and correct response to the final pattern.
