Table 2.

The Pearson product-moment correlation coefficient between the Tobii eye tracking measures for the modified Fagan test of infant development, and the Mullen Scales of Early Learning (MSEL) standardized composite cognitive and individual scale scores (N=31). The upper value in each cell is the correlation coefficient, and just below it is the corresponding probability value for that coefficient. Statistically significant coefficients are denoted with an asterisk.
