These graphs report per stimulus the time course of responses across the 24 listening sessions. Some report the general patterns of responses, other show how the listener’s responses changed over successive exposures
One of the remarkable consistencies of responses shown in this piece is the timing of changes in heart rate, an indication of respiratory sinus arrhythmia (RSA) and deep engagement with the music. See the darkening strips in the rows of instantaneous heart rate (top plot) at 17s, 40s, 55s, and 78s.
These responses were collected to Le rosier de trois couleurs de roses by Strada from the album Gadje. The piece was familiar to the listener.
