Age-related differences and commonalities in remembering earliest memories: a comparison of young and older adults.

We investigated age-related differences and commonalities in earliest memories, focusing on retrieval speed, recollection type (remember vs. know), retrieval type (direct vs. generative), age at the time of the event, and phenomenological characteristics. The sample consisted of 131 adults: 68 young adults (48.5% males; M_age = 20.29, Sa_ge = 1.53) and 63 older adults (47.6% males; M_age = 68.43, SD_age = 4.11). They reported their earliest memories, estimated their age at the time, indicated recollection and retrieval types, and rated event characteristics (e.g., importance, vividness). Results showed that older adults were significantly more likely to classify their memories as remembered and directly retrieved, whereas young adults had a more balanced distribution of the classifications. Directly retrieved memories were accessed more rapidly than generatively retrieved ones, and young adults demonstrated shorter retrieval latencies than older adults. Additionally, older adults dated their earliest memories to later age and rated them as significantly more vivid, emotionally intense, and personally meaningful. Recollection type was not associated with retrieval latency but linked to higher vividness and confidence. Overall, our findings demonstrate potential age-related shifts in the retrieval and subjective evaluation of earliest autobiographical memories.
