Fig. 3.

Three-way marginal effect plots. Green curves illustrate groups with mean $ToM$ scores, blue curves one SD above mean $ToM$, and red curves one SD below. In each set of three graphs, panels move from one SD below the mean group $g$ score (estimated by ACT) to the mean to one SD above. (A) Four-to-eight group size (negative) perturbation treatment. (B) High-to-low growth rate (negative) perturbation treatment. (C) Eight-to-four group size (positive) perturbation treatment. (D) Low-to-high growth rate (positive) perturbation treatment.
