Data from 40 older adults who produced autobiographical memories to word cu
es and to the request to list five important memories, and data from 60 old
er adults who answered factual multiple-choice questions for events spread
across their lives, were analyzed for gender differences. In spite of consi
derable statistical power, there were no gender differences in the distribu
tion of autobiographical memories over the lifespan, in the distribution of
important memories, in various ratings provided to these memories, or in t
he distribution of knowledge for events. The only gender difference found w
as that men performed better on factual questions about current events and
baseball. Thus, counter to what might be expected from Darwinian theory and
some behavioral data, gender differences were minimal.
