All results from linear mixed effect models are converted to ANOVA table with R function anova; p < 0.05 is indicated in bold; p < 0.10 is indicated in italics. The same models with weights added to account for variable amount of data collected from each infant and each condition are in Extended Data Table 2-1. Models testing for interaction between age and condition in each hemisphere are in Extended Data Table 2-2 (without weights) and Extended Data Table 2-3 (with weights).
