Do You See What I Mean? Corticospinal Excitability During Observation of Culture-Specific Gestures
Gesture type x Performer interaction (F(3,5) = 5.24, p = 0.053).
Post-hoc paired t-tests on percent change relative to the overall mean in motor evoked potential (MEP) responses show no differences in CSE while observing emblems performed by the Euro-American actor. In contrast, the observation of Nicaraguan emblems yielded higher CSE than American emblems (P = 0.004) and control ASL signs (P = 0.028) when performed by the Nicaraguan actor.
