“…With limited motor ability, it already becomes more difficult to perform the aforementioned elementary rhythmic extremity movements and babbling articulations, in the second half year of life, which may be so crucial for setting up connections between action and perceptual brain circuits and serve later as a vehicle for repetitions. Incidentally, as we have seen in Sections 2 and 4, the ability to repeatedly articulate verbally (in babbling) and to move are amongst those early deficits present in autistic infants, and the resultant reduced production of vocal and motor acts has implications for the development of further social and cognitive domains, including empathy (Braadbaart, de Grauw, Perrett, Waiter, & Williams, 2014;Decety & Meltzoff, 2011;Meltzoff & Decety, 2003). Needham and Libertus (2011) link the development of reaching behaviours to the ability to interpret others' reaches as goal directed; the ability to crawl to that of representing space in a nonegocentric or allocentric manner; the ability to sit and reach and thus take part in hiding games to object permanence.…”
