individual sessions. The study involved 15 children aged three to five years old with autism, and used an between-conditions and within-subjects design with 12 weekly 30 minutes improvisational music therapy sessions compared with a control condition of 12 weekly 30 minutes play sessions with toy. Improvisational music sessions were shown to be more effective than play sessions in increasing eye contact, turn taking, emotional synchronicity and initiation of engagement. However, generalizability to settings other than the therapy sessions and the maintenance of the improvement were not assessed in this study.
