Of the three proposed mechanisms of Music Supported Therapy (MST) explained in the introduction, the findings of this study may be best explained by the emotion-motivation mechanism. Though dexterity scores were organized by whether the scores followed an active playing module, all participants experienced the same amount of music-listening and social interaction. Whether the participant was playing the music him/herself or observing, both groups were always hearing the same songs and scales for the same amount of time. The emotion-motivation mechanism states that this music-listening alone may increase cognitive processes like working memory and boost both mood and motivation. Therefore, these findings may mean that listening to piano music helps dexterity performance in older adults; but it does so if and only if the participants experience the music-listening module for a sufficient duration of time.
