Note: The mean proportion of trials on which infants were looking to the target picture across the Baseline and Late Target windows is shown on the left panel. Word-learning scores, or increases in looking to the target picture during the Target windows relative to Baseline, are shown on the right panel. One sample t tests comparing increase in proportion looking to target to chance (no difference): p≤.01 = **, p≤.05 = *.
