    Notes: Abstract In a group of heavy smokers, overnight abstinence from smoking facilitated the perception of briefly presented smoking words. Subjects in the nicotineabstinent condition accurately identified significantly more smoking-related words than food-related or neutral words. However, a group tested in a non-abstinent condition showed no significant differences in ability to identify the three different word types. Smokers deprived of cigarettes were also significantly better able to categorize smoking words than non-abstinent subjects. These results demonstrate an abstinence-based facilitation of processing smoking-related stimuli at the semantic level, consistent with the hypothesis that smoking-related concepts are activated, or primed, during deprivation from nicotine.

    Notes: Abstract Adult, male smokers were randomly assigned to be nicotine abstinent for 12 h (n=10) or to smoke normally for the same period of time (n=10). Performance on a modified version of the Stroop (1935) color-naming task, where subjects named the color of ink in which each of a series of words was written, showed that abstinent smokers took significantly longer to color-name words related to cigarette smoking (e.g., Lighter) than to color-name neutral control words (e.g., Pennant). Non-abstinent smokers showed a significant difference in the opposite direction. These results suggest that nicotine abstinence decreases the ability to ignore the meaning of smoking-related information. This finding supports the hypothesis that abstinence produces a content-specific shift in attentional focus. The present pattern of results cannot be explained by a general decrease in cognitive function due to nicotine abstinence.

    Notes: Abstract The stimuli controlling the rate at which people smoke cigarettes have not been clearly defined. On the hypothesis that smoking is basically nicotine-seeking behavior. nicotine available to the subject was experimentally manipulated through controlling cigarette size and nicotine content. In Experiment I, subjects given their own cigarettes in whole, half, quarter, and eighth lengths, increased the number of cigarettes smoked and number of puffs to compensate for reductions in size. Satisfaction was directly related to cigarette length. In Experiment II, subjects given special cigarettes delivering 0.2 or 2.0 mg nicotine/cigarette smoked significantly more of the low than of the high nicotine cigarettes and took significantly more puffs. As in Experiment I, significantly more quarter length than full length cigarettes were smoked, but total number of puffs did not differe. These results support the hypothesis that nicotine controls smoking behavior.
