Benefits of audiovisual memory encoding across the life span

Abstract

Although we live in a multisensory world, human memory has been traditionally studied concentrating on just one sensory modality, for example, either audition or vision. Yet, some previous studies have shown better memory performance for audiovisual information than for unisensory information. However, such studies are scarce and they have mainly focused on young adults. In the present series of studies, the effects of audiovisual encoding on later unisensory recognition memory performance were studied in children, young adults, and elderly people. In Studies I and II, these effects were studied in younger adults using both verbal and non-verbal audiovisual stimuli. Study III, in turn, investigated how audiovisual encoding affects recognition memory in school-aged children (mean age 10 years 4 months). Finally, Study IV compared how audiovisual encoding affects auditory recognition memory in elderly people (mean age 71 years) and young adults (mean age 23 years). Overall, recognition memory performance was better in all age groups when the stimulus to be memorized was initially accompanied by a semantically congruent stimulus in the other modality than when it was accompanied by a non-semantic stimulus in the other modality or by no stimulus. Altogether, the results of the present series of studies suggest that semantically congruent audiovisual experiences enhance memory encoding not only in young adults but also in children and elderly people. These results might be useful when developing educational practices for children and young adults, as well as when designing practical applications to alleviate mild memory problems due to normal aging.
