Abstract

Participants from four age groups, extending from early to late adulthood, recalled and dated autobiographical memories from across the lifespan. Memories were plotted in terms of age-at-encoding to outline lifespan memory retrieval curves for different age groups. The curves revealed that all age groups had a period of childhood amnesia - although the youngest group (20-year-old) recalled more childhood memories than the older groups. The curve fitting analysis revealed that the lifespan retrieval curve for the 20-year-old group was a straight line, thus no reminiscence bump for this group. Although the curve for 30-year-olds was not a straight line, it did not show any clear bump. The 40-year-olds, however, showed an inverted S-shaped curve with a clear bump covering the period from 6 to 25 years of age. Also the 50-year-olds showed bump that covered the age between 6 to 20 years. The findings suggest that the childhood amnesia is an unavoidable phenomenon in human life, and that people are more likely to show reminiscence bump when they reach their middle age.
