Association of social perception, motor/frontal abnormalities, and gesture performance. Upper panel: direct association between nonverbal social perception (PONS) and gesture performance (TULIA). Lower panel: inclusion of the mediator motor/frontal abnormalities (motor/frontal factor). Numbers indicate beta-weights. Note that the association between nonverbal social perception and gesture performance is weaker in the lower panel, suggesting a partial mediator effect of motor/frontal abnormalities.
