All results from linear mixed effect models converted to ANOVA with R function anova; p < 0.05 is indicated in bold; p < 0.10 is indicated in italics. Statistics for models to test for face selectivity in each hemisphere are reported in Extended Data Table 4-1 (without weights) and Extended Data Table 4-2 (with weights). ANOVA tables from models testing for age by condition interactions in each fROI for each hemisphere are reported in Extended Data Table 2-3 (without weights) and Extended Data Table 2-4 (with weights). ANOVA tables for effects of age and hemisphere on face selectivity with weights to account for variable amounts of data collected from each infant and each condition are reported in Extended Data Table 4-3. Effects of age on each condition in each hemisphere are reported in Extended Data Table 4-4. Tests for interactions between hemisphere and age on each condition are reported in Extended Data Table 4-5.
