Neural representations of the social versus nonsocial distinction and of affective meanings in touch scenes. Radar charts were used to plot the results (a pink line for the NT and a green line for the ASD group). Each of the 13 ROIs, ordered according to the implied brain network as indicated by the color of the surrounding circles, forms an individual axis. The node (anchor) on the spoke (axis) represents the beta coefficient of each ROI. a The beta coefficient from the multiple regression model in which the neural patterns of each of the ROIs were predicted based on the social vs. non-social factor. b The beta coefficient from the multiple regression model predicting the neural patterns based on perceived overall affect. The asterisks indicate the statistical significance (beta higher than zero) determined by the permutation tests at *p < 0.05, **p < 0.01, and ***p < 0.001 in the NT (pink) and ASD group (green). In a, we additionally plotted the correlation coefficient representing the noise ceiling of the neural data, derived from the reliability test (a red dashed line for the NT group and a blue dashed line for the ASD group)
