To support a study examining whether an improvisational music therapy program can improve outcomes for children with autism. In partnership with the University of Tennessee Health Science Center, researchers will test whether participation in the 12-week music program can improve neurological functioning of children with Autism Spectrum Disorder (ASD) and, furthermore, whether there is a relationship between children's engagement ability and activity within the mirror neuron system of children with ASD. The study will include a comparison group of neurotypical children. Assessments will include behavioral observations of engagement, affect, and interaction; surveys of parents and assessments of family quality of life; and brain imaging measurement using electroencephalography (EEG).
