The effects of smoking a low-nicotine (.6 mg) and a middle-nicotine (1.3 mg) cigarette (compared to a no-smoking control) on electro-dermal responding to a series of auditory stimuli and on spiral aftereffect (SAE) inhibition were measured with two groups of 12 subjects acting as their own controls. The middle-nicotine group (N = 12) showed decreased arousal, accelerated habituation rate, and fewer spontaneous fluctuations to the auditory stimuli; but a less (rather than more) rapid accumulation of SAE inhibition. For the low-nicotine group (N = 12), no significant effects were recorded.
