“…Even children as young as 6 months are able to keep track of objects moving synchronously on circular trajectories (Richardson & Kirkham, 2004). At the age of 6.5 years, children are able to track up to four moving objects (O'Hearn, Hoffman, & Landau, 2010;O'Hearn, Landau, & Hoffman, 2005; see also Brockhoff et al, 2016). Remarkably, even children suffering from autism spectrum disorders show a qualitatively similar pattern of development of object tracking as healthy children, although they reach the same quantitative level of tracking at a later biological age (Koldewyn, Weight, Kanwiyher, & Jiang, 2013; see also Griffith, Pennington, Wehner, & Rogers, 1999;Poirier, Martin, Gaigg, & Bowler, 2011).…”
