The Music-Imagery Mood Induction was reported in Mayer, Allen & Beauregard (1995) and is a handy and effective way to induce brief mood states in experimental participants.
Basically, experimental participants are asked to enter into a given mood. If they agree, they don headphonesand begin listening to music. After 1 min., they are signaled (by a light in our procedure) to read the first of a series of eight brief vignettes. The light signalled for them to proceed through the remaining seven vignettes every 30 sec..
The vignettes are available in the article, as are full descriptions of the musical pieces employed. The music clips also are available from the lab upon request (or can be purchased online).
