    Abstract

    Human movements are prospective (Delafield-Butt et al., 2018). They must anticipate ahead of time their lawful consequences (Delafield-Butt & Gangopadhyay, 2013; Trevarthen & Delafield-Butt, 2017a, 2017b). In children with autism, evidence indicates a common disruption to prospective movement may underpin its early pathogenesis (Trevarthen & Delafield-Butt, 2013) and may be a cardinal feature of autism (Fournier et al., 2006). Yet, more work is required to better characterize this possible ‘autism motor signature’ and to probe its neurodevelopmental origins. In this study, we employed smart tablet computers with touch-sensitive screens and embedded inertial movement sensors to ecologically record the subsecond motor kinematics of purposive, prospective movements made by children developing with and without autism.
