“…Eye-gaze following at 6 months has been shown to correlate with vocabulary size at 18 months (Morales et al, 2000;Morales, Mundy, & Rojas, 1998) and in noun learning, children can use eye-gaze, head posture and gesture to infer speakers' referential intention (e.g., Baldwin, 1991;Carpenter , Akhtar & Tomasello, 1998;Gergely, Bekkering & Király, 2002;Woodward & Sommerville, 2000).
