Two experiments examined own-age biases in younger adults', older adults', and children's verbal person memory. In line with findings from face recognition studies, Experiment 1 showed that younger adults had a better recall of own-age than of other-age targets, while older adults were unaffected by target age. Participants' self-reported interest in targets did not predict target memory. Experiment 2, which examined children's and younger adults' memory of own- and other-age targets, showed an own-age advantage in children's but not in younger adults' verbal person memory. Differences in expertise of own-/other-age targets, in combination with a development of expertise throughout the Hfespan, may account for the findings, although alternative explanations should be considered. Implications for theory and practice are discussed.
