Effortful processing is a requirement for nicotime-induced improvements in memory

We report two studies examining the effects of nicotine on memory in minimally deprived smokers. In experiment 1, semantically related words were recalled significantly better than unrelated words following nicotine, even when volunteers were explicitly instructed to target the unrelated word set for recall. Experiment 2 examined the effect of nicotine on two different types of lexical association: association by joint category membership (semantically related items), and association by derived meaning ('encapsulated' word pairs). Nicotine-induced improvements in recall were observed only for category associates and not for encapsulated word pairs. This implies that explicit, effortful processing of material in the presence of nicotine is necessary for improved recall performance to be observed.
