The role of spectacles in facial memory: a replication and extension

A total of 187 subjects in three conditions involving 1- or 3-sec. exposure times and 10-min. or 7-day delays were shown 20 photographs of faces, half of which were bespectacled, and then tested from a set of 40 consisting of the original 20 mixed up with 20 new ones, half of which were also bespectacled. Accuracy of recognition declined with shorter exposure and longer delay and was lower for faces with than without spectacles at the shorter delay. In all three conditions, there were more false-alarms for faces with than without glasses. It is concluded that eyeglasses did not serve as an efficient discriminating feature in recognition memory, and it is recommended that positive eyewitness identification of people wearing spectacles be treated with particular caution.
