Stage 1 Registered Report Manuscript: Effects of familiar music exposure on deliberate retrieval of remote episodic and semantic memories in healthy aging adults

Familiar music facilitates memory retrieval in adults with dementia. However, mechanisms behind this effect, and its generality, are unclear because of a lack of parallel work in healthy aging. In particular, exposure to familiar music enhances spontaneous recall of memories directly cued by the music, but it is unknown whether such effects extend to deliberate recall more generally — e.g., to memories not directly linked to the music being played. It is also unclear whether familiar music cues boost recall of specific episodes versus more generalized semantic memories, or whether its effects are partly driven by domain-general mechanisms (e.g., improved mood). Here, we will examine the effects of familiar music on deliberate recall and differentiate potential underlying mechanisms. We will expose healthy adults ages 65-80 years old (N = 75) to familiar music clips from earlier in life, unfamiliar music clips, and non-musical audio clips across three study sessions. After each clip, we will assess free recall of remote memories for pre-selected events. We hypothesize that familiar music may enhance recall of specific events, such that participants will recall more episodic details after exposure to familiar music than unfamiliar music or non-musical audio clips (Preprint and materials at https://osf.io/kjnwd/).
