Personal recollections constitute autobiographical memory that develops intensively during the preschool years. The two-wave longitudinal study focuses on gender differences in preschool children's independent recollections. The same children (N = 275; 140 boys, 135 girls) were asked to talk about their previous birthday and the past weekend at the ages of 4 and 6. Interactions were coded for content. Boys talked more about themselves and about different nonsocial aspects of the events. Girls talked more about the other people with whom they had jointly experienced the past event. It seems that gender differences in children's recollections appear early and increase during the preschool period.
