Notes

A closely related type of evidence originally offered in support of PRS theory emerged from experiments demonstrating the importance of goals and context in the evocation of deontic schemas. For example, Cheng and Holyoak (1985, Experiment 1) found that an identically stated rule either would or would not yield facilitation depending on whether the context made it clear that the rule was an established regulation for which it was necessary to check for possible violations. More recent research on the influence of subjects' perspectives on deontic reasoning has provided a richer and more detailed picture of contextual influences (see Manktelow & Over, this volume, Chapter 5). The findings regarding perspective effects on selection performance have led to a more explicit theoretical integration of the permission and obligation schemas, yielding a new prediction (equivalent performance for stated rules that match either Rule P3 or Rule PI of the permission schema) that has been confirmed by an experimental test.
