Using Intersubject Correlation (ISC) of Dance to Study Biological Motion Processing in Autism

Several recent papers have used the technique of Intersubject Correlation (ISC) of fMRI data to study differences between typical individuals and those on the autism spectrum when they watch movies while being scanned (Byrge, et al., 2015; Salmi et al., 2013; Hasson et al., 2009). In this presentation I discuss preliminary results from a study using ISC of solo dances that explored the differences in biological motion processing in autism noted previously by our lab (McKay, et al., 2012). This will include introductory discussion of ISC studies of dance that have highlighted the possible confounding effect of using edited videos composed of different camera views (Herbec et al., 2015) as well as the motion signal that appears related to regions of highest ISC (Noble et al., 2014; Jola et al., 2013).
