The ability of middle-aged adults to recall their body size and events
occurring up to 40 years earlier was assessed. Ninety-one subjects re
called their relative height, weight, and fatness during childhood, ea
rly adolescence and late adolescence. Accuracy of these memories was c
ompared with the accuracy of current reports. The ability to accuratel
y date benchmarks of their maturation such as menarche and year of max
imal growth in height was also examined. Accuracy of reports did not d
ecline uniformly over time. In general, reports of childhood physical
characteristics were at least as accurate as reports of current charac
teristics; that is, they did not differ significantly from current rep
orts. Males were less accurate in their reports of relative height and
fatness during early adolescence and childhood.
