Figure 2.

Association between Bird/Alligator go (activation) and no-go (inhibition) scores at 30, 36, and 42 months of age. Correlations represent Spearman’s rho to account for extreme values (see Table S5). Pearson correlations are presented in Table 1. To address the problem of hidden points in the scatterplot because of multiple observed scores occupying the same coordinate location (i.e., over-plotting), lighter gray points represent fewer observed scores, whereas darker points represent more observed scores.
