S7 ) and a nearly significant interaction between stimulus and group ( χ 2 (18) = 9.224, p = 0.056), explained by a significant difference in Nc latency between infants with (FH-ASD) and without (noFH-noASD+FH-noASD) later ASD for the social (FD + FA) vs non-social (Noise) stimulus contrast ( β = −20.091, s.e. = 6.796, p = 0.003) such that, descriptively, shorter latencies to faces than Noise were observed in the FH-ASD group, while longer latencies to faces than Noise were observed in the noFH-noASD and FH-noASD groups.
