(A) The location of the fNIRS channels with significant increases in HbO₂ for the Face_Direct compared to the Face_Averted condition. Grey numbers indicate excluded channels (1 and 5). (B) Time course of the grand averaged haemodynamic responses over the same two channels for both conditions. The grey area indicates the interval where the difference in the HbO₂ response between the two conditions reached significance.
