Abstract
The effects of cigarette-smoking in an immediate memory task were studied in two groups of 25 female students (habitual smokers) tested either under a control (no smoking) condition or after smoking one cigarette. The memory task, requiring immediate serial recall of eight words, showed no differences between the two groups. Subjects were, however, also tested on recall of the position of words on the screen (each word could appear in any of the four corners). On this measure of incidental recall, the non-smoking group was far superior to the smoking group. This finding is in agreement with results obtained with noise-induced arousal and with the view that attentional selectivity is greater during increased arousal.
