ObjectivesPersonalized music playlists are increasingly being utilized in aged care settings. This study aims to investigate how musical features influence the affective response to music of people with probable dementia.MethodsA factorial experiment (2 × 2 × 3) was conducted to investigate the influence of tempo (fast, slow), mode (major, minor), and lyrics (none, negative, positive). Ninety-nine people with probable dementia were randomly assigned to 3 conditions, listening to 3 personalized playlists. Galvanic skin response and activation of facial action units were measured.ResultsMusic with fast tempos increased arousal and reduced enjoyment. Music in minor keys increased activation of the depressor anguli oris, suggesting increased sadness. Lyrics had no significant effect on response.DiscussionThe findings demonstrate that both tempo and mode influenced the response of the listener. As well as accounting for personal preferences, music for people with dementia should be carefully targeted toward the affective outcome desired.
