Results of ROI-based MVPA analyses for voxel count from 50 to 500. a, Classification accuracies (± within-subjects normalized SEM) for multiclass cross-decoding of single bodies patterns in facing dyads (light gray lines) and nonfacing dyads (dark gray lines), in each individually defined ROI (EBA, FBA, OFA, FFA, PPA, and EVC) using voxels counts from 50 to 500 voxels. Horizontal dashed bars represent the chance level (25%) b, Classification accuracies (± within-subjects normalized SEM) for multiclass cross-decoding of synthetic-mean patterns from facing dyads (light gray lines) and nonfacing dyads (dark gray lines), in each ROI using voxels counts from 50 to 500 voxels. Horizontal dashed bars represent the chance level (12.5%).
