in all four ERP measures in both males and females (1st row), in both larger and smaller Amounts (3rd row) and in all the regions (5th row). The larger Amount produced significantly higher ORN amplitude and shorter ORN latency (than the smaller amount) in males; ORP amplitudes were higher for larger Amount in both genders but ORP latencies were not significant between the Amounts (Fig. 6, 2nd row). Only the amplitudes (and not the latencies) of ORN and ORP significantly differentiated the Amounts in many of the scalp regions (Fig. 6, 6th row). No gender effect was observed in any of the scalp regions (Fig.6, 4th row).
