Tabulated is the p–value of the separation between the three groups (Controls, DD, and DL) assessed through permutation testing of the class labels assigned by a non-linear SVM classifier. The values in brackets are the p–value of the change in SVM classification accuracy due to product-size and task-difficulty parametric modulations, respectively. Dashes indicate “not significant at any p < 0.1.”
