A novel study: fragmented and holistic forgetting

According to recent theoretical work, certain event memories are more likely to be remembered or forgotten in their entirety. This prior work focused on collections of concepts, such as person-location-object triples. To explore this idea with complex materials, we created triples of people, locations, objects, or activities from events in real-world novels. People who had read one of the included novels were provided with one element from these triples (the cue) and asked to identify which of six alternatives best went with it. The results revealed that memory for the narrative events remained stable across many years. Moreover, people recalled events in a more holistic manner than would be expected by chance. This was more likely the more causally important an event was. This pattern of performance also remained stable over time. Our results are consistent with the idea that event models involve integrating separate elements into a single coherent representation, and this is likely to stay integrated over long periods of time. However, the degree to which this is so appears to be related to how well-integrated the information is within a larger set of events.
