Memory improvement in aging as a function of exposure to mood-matching music.

Abstract This study examined the effect of matching musical emotion and the mood of the listener on working memory and free recall in normal aging. Memory measures were taken at baseline in healthy young and older participants, and, following a happy or sad mood induction, again after exposure to both mood-matching and -mismatching music in a counterbalanced repeated measures design. Compared to baseline, [i] recall was greater following mood-matching than mood-mismatching music in both groups, and was reduced following mood-mismatching music in older adults, [ii] working memory was greater in the mood-matching condition, but did not differ from baseline in the mismatching condition. The results have significant implications for the increasingly popular forms of intervention involving music used with older populations experiencing cognitive decline.
