Younger and older adults' recall of typical and atypical actions from script-based text: evidence for interruption...

In the present research, younger (mean age 20) and older (mean age 78) adults' perception and recall of scripted and nonscripted actions were examined. Two primary types of nonscripted or atypical actions were presented: those that interrupted the sequence of the script and those that were irrelevant to the script. Script-irrelevant actions also varied in terms of how plausible they were in relationship to both the sentence they were embedded in and the context of the story. Across experiments, both younger and older adults recalled script-interruptive actions better than all other actions, including script actions. In addition, an unexpected finding was that both younger and older adults recalled implausible (bizarre) script-irrelevant actions better than script actions. This latter finding suggests that a bizarre-imagery effect may operate in both younger and older adults. Older adults' better recall of atypical actions over script actions is noteworthy, as these results question the assumption that older adults show an increased reliance on their schematic knowledge structures to recall. Contrary to expectations, older adults showed better recall of actions that required more active story integration (interruptive and implausible atypical actions) than actions requiring less integration (script and plausible atypical actions).
