Memory for script actions: effects of relevance and detail expectancy.

Script actions that varied both in relevance to the script and in the expectancy of their details were developed. In Experiment 1, recall of these actions was tested. Actions of medium relevance were recalled better than actions of high or low relevance, whether or not details were presented. However, the unexpected details themselves were recalled better than the expected details. In Experiment 2, recognition was lowest for high-relevance actions but medium- and low-relevance actions did not differ. Actions with unexpected details were recognized better than actions with expected details, which tended to be better than generic actions. The results were interpreted as showing that both the relevance and the expectancy of the details in script actions are important in memory, but that the two dimensions may play different roles.
