Interruption and bizarreness effects in the recall of script-based text

Abstract

Recall of script, script-irrelevant, and script-interruptive actions in script-based stories was examined in four experiments. By varying the plausibility of the script-irrelevant and the script-interruptive actions, the bizarreness effect (i.e., enhanced recall for bizarre, implausible actions) was assessed within the context of script-based text. In addition, presentation of script-interruptive actions allowed for an assessment of the interruption effect (i.e., enhanced recall for interruptive actions). A bizarreness effect was found, to the extent that implausible script-irrelevant actions were better recalled than their more plausible counterparts and script actions. However, implausible actions were not better recalled than script-interruptive actions, nor did bizarreness significantly enhance recall of script-interruptive actions. These results are discussed in terms of recent assumptions underlying interruptions underlying interruption and bizarreness effects, and in terms of recent assumptions about how scripted and nonscripted actions are retained in memory.
