Free recall accuracy for common and bizarre verbal information

A large body of empirical research suggests better free recall for bizarre than common verbal information; however, the bulk of those studies used a method that does not consider the contextual and relational accuracy of recovered memories. The conclusions drawn from that research therefore are based on tests of memory not for holistic stimuli but for decontextualized memory fragments. In response to this anomaly and recent findings suggesting that bizarre memories are more likely to be distorted than common memories, a holistic analysis of free recall for common and bizarre verbal material was conducted. Two experiments indicated that bizarreness both facilitates and disrupts recall. Specifically, better recall (both in part and in full) was found for bizarre information, but a greater tendency to merge bizarre memory fragments into other partially recovered memories was also found. This pattern of results was demonstrated under immediate and delayed testing conditions (Experiment 1) and using both incidental and intentional learning procedures (Experiment 2). Overall, the results are consistent with a weak account of disruption caused by bizarreness.
