Results of exploratory SEM analysis. Mean path coefficients of the model for semantic processing network, including left inferior frontal gyrus (LIFG), homotopic right inferior frontal gyrus (RIFG), left middle temporal gyrus (LMTG), and right extrastriate cortex (RESC), in TD and ASD groups. Models are shown separately for TD group (A) and ASD group (B). Line thickness reflects connection strength; red indicates positive connections, blue a negative connection. Path coefficients for subsamples of participants with non-significant χ2 are shown in brackets.
