Activity Analysis published in Music Perception

The Activity Analysis paper has been published in Music Perception!

Titled “Activity Analysis and Coordination in Continuous Responses to Music”, this paper explains what we can learn about the consistency of activity in continuous responses to music using the example of Continuous Ratings and (with the appendicies) all the technical details behind the results.

Abstract: Music affects us physically and emotionally. Determining when changes in these reactions tend to manifest themselves can help us understand how and why. Activity Analysis quantifies alignment of response events across listeners and listenings through continuous responses to musical works. Its coordination tests allow us to determine if there is enough inter-response coherence to merit linking their summary time series to the musical event structure and to identify moments of exceptional alignment in response events. In this paper, we apply Activity Analysis to continuous ratings from several music experiments, using this wealth of data to compare its performance with that of statistics used in previous studies. We compare the Coordination Scores and nonparametric measures of local activity coordination to other coherence measures, including those derived from correlations and Cronbach’s α. Activity Analysis reveals the variation in coordination of participants’ responses for different musical works, picks out moments of coordination in response to different interpretations of the same music, and demonstrates that responses along the two dimensions in continuous 2D rating tasks can be independent.

Million thanks to my co-author and mentor, Prof. Stephen McAdams, whose steadfast support made this work possible, and the patience of our editor at Music Perception, Prof. David Temperley.
