The present study relates subject-paced rapid information processing to different components of event-related brain potentials in an attempt to gain more information about changes in mental performance in relation to alveolar smoke absorption as assessed by expired air CO measurement. The task consisted in the presentation of pseudorandom sequences of single digits, and the subjects had to respond to each sequence of three odd or three even digits. The triplets evoked a typical late negativity in the event-related potential between the second and third digit as well as a P300 component following the third digit. In 21 smokers, task performance, event-related potentials and tidal air CO concentration were measured before and after smoking a cigarette. The results revealed increases in performance and P300 magnitude from pre- to postsmoking which were unaffected by the amount of CO absorption. A differential trend was seen, however, with the late negativity, which increased from pre- to postsmoking only in subjects with a large amount of CO absorption. The results support the assumption of the distraction arousal model used as an interpretation of these effects on contingent negative variation and suggest that high CO absorbing smokers possibly depend more on neuropharmacological effects of smoking than smokers with a low amount of CO absorption.

“…A view of the individual as an active motor-sensory system rather than a passive sensory recipient may offer an appropriate model for investigating the regulatory role of personality and be haviour. O'Connor [ 1982O'Connor [ , 1984 has proposed a motor-sensory model of personality and smoking, according to which personality differences in habitual motor set mediate the effects of smoking. Extraverts tend to smoke in situa tions where that motor activity is low, as a consequence they inhale nicotine in order to stimulate their noradren ergic system and produce gross motor activation via frontal-central cortical regions.…”

Motor potentials associated with a motor task and with the initiation of the smoking act were recorded from two groups of 5 introverted and 5 extraverted smokers during sham and real smoking sessions on two separate occasions. The aim was to test hypotheses derived by O’Connor from the motor model of smoking: firstly, that change in background motor set would alter the smoker’s smoking pattern, and secondly, that smoking would principally affect extraverts’ general motor preparation (as measured by motor potentials preceeding a tapping task), whilst improving introverts’ selective inhibition (as measured by performance on a tracking task requiring skillful co-ordination). Smoking did increase the motor readiness potential preceding tapping in extraverts. Smoking decreased involuntary rest pauses of introverts and their error on the tracking task. There were, however, no differences in puff parameters across motor conditions. But larger motor potentials preceding the smoking act in introverts indicated a greater involvement of introverts in the smoking act itself. The results offer limited support to the proposal of the motor model that motor demand regulates both the motivation to smoke and the effects of smoking.
