Goal-Directed and Goal-Less Imitation in Autism Spectrum Disorder

Abstract: To investigate how people with Autism are affected by the presence of goals during imitation, we conducted a study to measure movement kinematics and eye movements during the imitation of goal-directed and goal-less hand movements. Our results showed that a control group imitated changes in movement kinematics and increased the level that they tracked the hand with their eyes, in the goal-less compared to goal-direction condition. In contrast, the ASD group exhibited more goal-directed eye movements, and faile… Show more

“…Deficits in motor adaption implicate the cerebellum, where cell abnormalities in the cerebellar vermis and hemispheres are a robust feature of ASC (Fatemi et al, 2012;Rogers et al, 2013). Several studies suggest that children with ASC rely on proprioceptive feedback for motor adaptation and are impaired when learning motor skills through visual input alone (Izawa et al, 2012;Mostofsky & Ewen, 2011;Sharer, Mostofsky, Pascual-Leone, & Oberman, 2015;Vanvuchelen et al, 2007;Wild, Poliakoff, Jerrison, & Gowen, 2012). Hyposensitivity and hypersensitivity to visual and proprioceptive feedback respectively is indeed correlated with abnormalities in the anterior, sensorimotor aspect of the cerebellum in children with ASC (Marko et al, 2015).…”

“…Imitation of meaningless actions, and the way in which actions are performed, referred to as 'style' (Hobson & Lee, 1999) or 'adverbial aspects' (Perra et al, 2008), appears to be more affected (see also Wild, Poliakoff, Jerrison, & Gowen, 2012). However, the evidence base remains poor.…”

“…Recent studies have begun to explore the use of kinematics to explore imitation (Wild, Poliakoff, Jerrison, & Gowen, 2010;Wild et al, 2012 the laboratory environment using a portable computer fitted with a touch-sensitive screen (Culmer, Levesley, Mon-Williams, & Williams, 2009). This makes it possible to compare the kinematics of an action executed by one person (the model), with the kinematics of an action executed by another (the actor) who has seen the action and is being asked to copy it, permitting measurement of imitation fidelity on several levels.…”

“…They do, however, exhibit intact goal-directed imitation (Wild et al 2012). Providing feedback to highlight the task goal may result in improved imitation of the observed eye contact behaviour.…”

“…Detailed evidence of the effectiveness of isolated aspects (such as the type of extrinsic verbal reinforcement) is lacking (Bhat et al 2011). Because children with AD exhibit intact goaldirected imitation (Wild et al 2012), providing feedback to highlight the task goal may not only benefit the motivation to imitate but also improve the motor learning which takes place during eye contact imitation. This hypothesis led to the following research question: What is the effect of two types of augmented feedback when establishing eye contact in a child with AD?…”
