Average amplitude of P2 component (in μV) for each condition.

		Arousal
		Low M (SEM)	Medium M (SEM)	High M (SEM)
Significance	Low	3.20 (0.28)	2.53 (0.28)	3.16 (0.31)	2.96 (0.17)
	Medium	3.11 (0.32)	3.00 (0.32)	3.71 (0.29)	3.27 (0.18)
	High	2.65 (0.25)	2.77 (0.33)	2.98 (0.32)	2.80 (0.17)
	Total	2.98 (0.16)	2.77 (0.18)	3.28 (0.18)	3.01 (0.10)

The shading illustrates the greatest differences between conditions measured by simple contrasts. The amplitude in condition marked in dark gray was higher than the amplitudes in conditions marked in light gray (please compare with Table 3).
