Table 3.

Pearson’s correlations (r) for initiating joint attention, anticipatory smiling, and reactive smiling, at each age.

	Study 1 (n = 22)			Study 2 (n = 39)
	8–10 Months	10–12 Months	8–12 Months	9–12 Months
Rate of IJA Episodesa	0.17	0.58**	0.12	0.43**
Anticipatory Smiling	0.56*	0.23	0.28	0.04
Reactive Smiling	−0.05	0.46	−0.14	0.14

Note. IJA = initiating joint attention; Anticipatory Smiling = proportion of IJA episodes involving anticipatory smiles; Reactive Smiling = proportion of IJA episodes involving reactive smiles.
