An investigation into the effects of nicotine gum on short-term memory

An investigation into the effects of nicotine gum on short-term memory Using a between-subjects 2 × 2 × 2 factorial design, 60 smokers and 60 non-smokers (equal number of males and females) performed a short-term memory task requiring delayed free recall of a visually presented supraspan word list. Using a double-blind procedure, half the subjects chewed nicotine gum and the other half chewed placebo gum prior to performing the memory task. Results support previous research findings which show that nicotine significantly improves short-term memory. Sex differences were also investigated, but findings showed no significant differences between male and female subjects. Methodological considerations are discussed and directions for future research are suggested. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Psychopharmacology Springer Journals

Abstract

Using a between-subjects 2 × 2 × 2 factorial design, 60 smokers and 60 non-smokers (equal number of males and females) performed a short-term memory task requiring delayed free recall of a visually presented supraspan word list. Using a double-blind procedure, half the subjects chewed nicotine gum and the other half chewed placebo gum prior to performing the memory task. Results support previous research findings which show that nicotine significantly improves short-term memory. Sex differences were also investigated, but findings showed no significant differences between male and female subjects. Methodological considerations are discussed and directions for future research are suggested.
