sedative response among more impulsive individuals was observable during the first half of clamped IV ethanol infusion. The modified differentiator model, which states that stronger stimulant and weaker sedative response among higher-risk drinkers are observable across limbs of the blood alcohol curve, would predict this finding. In contrast, the original differentiator model posits weaker sedation among higher-risk drinkers only during the descending limb of the blood alcohol curve (Newlin and Thomson, 1990).
