Abstract

Abstract Research on mental imagery has demonstrated the importance of visual imagery to recall performance. Little attention, however, has been paid to the mnemonic value of auditory imagery. The present experiments addressed the influence of auditory and visual imagery on free recall. Characteristic sounds, pictures, or printed verbal labels of 40 common items were presented sequentially to adult subjects, who were asked to recall them after a 2-min retention interval. Pictures and characteristic sounds were associated with significantly better recall than were verbal labels alone, indicating that auditory imagery has mnemonic value similar to that of visual imagery. This effect was confirmed by further experiments. However, the effects of auditory and visual imagery on free recall were not shown to be additive.
