The hemisphere by fixation interaction (F(5,100) = 8.5, p b 0.001,
ηp 2 = 0.29) was also significant. When each fixation was analyzed
separately, only fixation on the right eye yielded a significant effect of
hemisphere (F(1,20) = 5.2, p b 0.05) due to a shorter latency on the
right than on the left hemisphere. As seen for P1 (see Supplementary
data), when fixation was on the right eye, the rest of the face was
situated in the left hemifield, thus yielding faster latency in the right
hemisphere. Although non-significant, the pattern was opposite for
the left eye fixation, with shorter latency on the left than on the right
hemisphere (Fig. 3).
