Human Sensitivity to Community Structure Is Robust to Topological Variation

Table 1

Model I lists the coefficients, t-values, and p-values for each predictor in a model examining the effect of Node Type (pre-transition versus transition), Community (reverse-Helmert coded based on graph type), Trial, and their interactions on RTs specific to boundary nodes. Model II lists these values for predictors in a model examining the effect of Community, Trial, and the interaction of these predictors for all nontransition RTs. Significant values (corresponding to p < 0.05 via the Sattherwaite approximation) are bolded.
