Abstract: Rationale Nicotine has been shown to improve both memory and attention when assessed through speeded motor responses. Since very few studies have assessed effects of nicotine on visual attention using measures that are uncontaminated by motoric effects, nicotine’s attentional effects may, at least partially, be due to speeding of motor function. Objectives Using an unspeeded, accuracy-based test, the CombiTVA paradigm, we examined whether nicotine enhances attention when it is measured independently of motor processing. Methods We modelled da...
