Earliest recollections of childhood: a demographic analysis.

A theory has recently been advanced which proposes that the development autobiographical recollection is shaped by a child's participation in discussions of events with adults (e.g. Nelson, 1988; Snow, 1990). A logical prediction of the theory is that demographic factors related to the nature of linguistic environments might be associated with differences in the development of autobiographical recollection. Four questionnaire studies that test this prediction are presented. The results, on a total of 768 subjects, show that the age of earliest memory increases across birth order, is slightly earlier for females than for males, and is earlier for Caucasians than for Asians. These findings are discussed in light of previous research showing that parents interact and talk more with first-borns and with girls, and in light of differences between Western and Asian cultures in socialization goals and the significance of autobiography in the development of self-concept.
