Pattern of results for the Control and ASD groups at the P1 and N170

	Faces vs Houses		Upright vs Inverted
	Controls	ASD	Controls	ASD
Amplitude
P1 amp	F > H	F > H	FU > FI	FI = FU
N170 amp	F < H	F < H	U < I	U < I
Slope	F > H	F > H	I > U	I = U
			FI > FU	FI = FU
Latency
P1 latency	F < H	F < H	U < I	U < I
N170 latency	F < H	F < H	U < I	U < I

Key: F Face; H House; U Upright; I Inverted; FI Face Inverted; FU Face Upright; < more negative amplitude or faster than in latency; > more positive amplitude or greater change in slope; = equivalent.

Significant differences between groups are in bold.
