    Notes: Abstract After training in a passive avoidance task, mice were detained in the safe compartment of the conditioning apparatus. This detention produced an impairment of rentention on the retest trial. Detention did not prolong the cycloheximide susceptible phase of memory formation. A summation of the amnestic effects of the two treatments occurred only at a time when both were effective alone. Cycloheximide was without effect upon the detention experience itself.

    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: Summary Delay of punishment 0, 30, 60, 120 and 240 sec after the step-through response in a one trial passive avoidance task was used to obtain in mice conditioned responses of different strengths. Both cycloheximide and ECS given immediately after training had a greater amnesic effect upon the weaker conditioned responses obtained with the longer delays of punishment. A proactive effect of ECS, but not of cycloheximide, was demonstrated with the weaker conditioned responses.
