      abstract     = {BackgroundOne of the main diagnostic features of
                      individuals with autism spectrum disorders is nonverbal
                      behaviour difficulties during naturalistic social
                      interactions. The ‘Interactional Heterogeneity
                      Hypothesis’ of ASD proposes that the degree to which
                      individuals share a common ground substantially influences
                      their ability to achieve smooth social
                      interactions.MethodsTo test this hypothesis, we filmed 29
                      autistic and 29 matched typically developed adults engaged
                      in several conversational tasks. Windowed cross-lagged
                      correlations were computed using the time series of motion
                      energy of both individuals in a dyad. These coefficients
                      were then compared across the three dyad types that were
                      homo- or heterogenous with respect to diagnosis: pairs of
                      two autistic individuals, two typically developed
                      individuals or pairs of one autistic and one typically
                      developed person.ResultsWe found that all dyad types
                      achieved above-chance interpersonal synchrony, but that
                      synchrony was more expressed in typical dyads compared to
                      both autistic and mixed dyads.LimitationsThe method
                      presented here provides only one, albeit objective and
                      robust, approach to explore synchrony. The methodological
                      choices as well as the lack of consideration for other
                      communication modalities may limit our interpretation of the
                      findings. Moreover, the sample size is small with respect to
                      exploring associations between synchrony and various outcome
                      and social skill measures.ConclusionsThe present results do
                      not provide support for the Interactional Heterogeneity
                      Hypothesis given that autistic individuals do not coordinate
                      better when interacting with another autistic individual,
                      compared to when interacting with a typical individual.},
