“…TG is a critical achievement, demonstrating the child’s ability to use coordinated joint attention (CJA). Several research groups have argued that the appearance of TG to coordinate attention between objects and persons marks the transition from preintentional to intentional communication, which is associated with significant neurological change and is highly predictive of later language development (Beuker, Rommelse, Donders, & Buitelaar, 2013; McCathern & Warren, 1996; Mundy & Newell, 2007; Mundy, Sigman, & Kasari, 1990). Thus, as a signal of CJA, TG reflects the child’s growing ability to monitor, relate, and integrate the behavior of self and others (Mundy & Acra, 2006), which supports the development of contingent communication between child and caregiver (Dunst, Trivette, Raab, & Masiello, 2008).…”
