Replicating autobiographical memory research using social media: a case study.

The durability of memories for personally experienced events and the effectiveness of naturalistically generated cues of those events were investigated via a case study using Timehop to re-present information from Facebook, Twitter, and the iPhone photograph archive from the past six years to generate autobiographical memories. Replicating prior longitudinal self-studies of remembering, recency predicted successful recall of specific events. Prior research showing images to be more evocative of autobiographical remembering than text was also replicated here. Results also supported claims that direct retrieval is a common mode of remembering. Somewhat surprisingly, retrieval of autobiographical memories had little influence on ongoing affect, cognition, and behaviour. This is suggested as "proof of concept" that social media data allows for modern replication of diary-type studies and expansion beyond typical participant pools. The interrelated functions of social media for remembering and of autobiographical remembering to social media can also be explored with this method.
