Preschool children's discrimination of age

This study compared abilities of 4- and 5-yr.-olds to be accurate in connoting "who is older" without using size representation as a cue. An age discrimination task was administered to 30 4-yr.-olds and 30 5-yr.-olds. Analysis indicated that the 5-yr.-old children had better ability to discriminate age than the 4-yr.-old children but were not equal to adults. No significant sex differences were found in the children's ability to discriminate age.
