 Healthy non-smokers will be screened for study eligibility and receive training on three different attention tasks. Over four test session, participants will then perform these tasks after receiving 1 a placebo patch and a placebo capsule, 2 a nicotine patch 7 mg24 hrs and a placebo capsule, 3 a placebo patch and a galantamine capsule, and 4 a nicotine patch and a galantamine capsule. The four test session are performed on separate days and take approximately 7 hours each. During the first 5 hours, the participant may read or watch TV while nicotine andor galantamine are being absorbed. During the last two hours, the participant will perform the attention tasks on a computer. The investigators hypothesize that performance-enhancing effects of nicotine, which were documented in previous research, will be larger in the presence than in the absence of galantamine. This proof-of-concept would have implications for the development of drugs for the treatment of conditions such as Alzheimers disease or schizophrenia.
