Toddlers' intermodal and verbal knowledge about gender was examined in
two experiments. In the first, 18-month-olds were presented with phot
os of adult male and female faces paired with a female or male voice,
or with the labels lady and man. Children spent more time looking at t
he pictures matching the voices than at the same pictures paired with
mismatching voices. However, only girls could match the gender labels
to the appropriate faces. In Experiment 2, child pictures and labels (
boy and girl) replaced the adult stimuli. Unexpectedly, 18- and 24-mon
th-old children failed to match the faces and voices of children. Howe
ver boy was understood by the age of 18 months. These results suggest
that toddlers' knowledge about gender labels has been underestimated.
