Reactions to Unexpected Events

The present investigation sought to examine the differential effects of expected versus unexpected information on interpretive activity. It was predicted that expected information would involve an automatic mode of processing, while unexpected information would prompt a more controlled mode. More specifically, we examined the proposition that unexpected or inconsistent information would lead to attempts at generating explanations for the discrepancy, and that the resulting explanations would tend toward maintaining the original expectation. Subjects were exposed to a general description of an actor, and then received additional information consistent or inconsistent with that description; the strength of or confidence in the original expectation was also varied. The primary experimental task involved subjects retelling these stories. The data revealed that, relative to processing consistent information, subjects tended to provide explanations spontaneously for the unexpected events. These findings were discussed in terms of unexpected events producing greater observer involvement, which in turn increases the likelihood of interpretive activity.
