“…Miles (1895) conducted a survey of adults' childhood experiences and among other things, asked them to think about the earliest event they could remember, and how old they were at the time. This and subsequent such surveys (e.g., Dudycha & Dudycha, 1933a, 1933bHenri & Henri, 1895, 1896, 1898Kihlstrom & Harackiewicz, 1982) have produced one of the most consistent and robust findings in the psychological literature, namely, that the average age of earliest memory among adults in Western cultures is age 3 to 4 years (see, e.g., Wang, 2006Wang, , 2014, for discussions of crosscultural differences in average age of earliest memory). Moreover, the same average age of earliest memory is found whether the source of data is a survey, free recall (e.g., Bauer et al, in press;Waldfogel, 1948;Weigle & Bauer, 2000;West & Bauer, 1999), or response to a cue word prompt (e.g., Rubin & Schulkind, 1997; though see Wang, Conway, & Hou, 2004, for evidence that repeated probes can produce earlier estimates).…”
