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 distinctive response behaviour was the zygomaticus activity (smiling) in the second verse of this familiar chanson, reported in the third and fourth plots below. This is very common around 60s, where the corrugator (frowning muscles in the forehead) was also active in the resultant amused expression. The trumpet solo at the end was more simply pleasurable, without any brow activity.
These responses were collected to Boum! by Charles Trenet. The piece was very familiar to the listener, an old favourite.Finding the exact album source is difficult but the recording had been remastered. Below is either the same or a very similar recording.
