Evidence of more rapid stimulus evaluation following cigarette smoking


, : Evidence of more rapid stimulus evaluation following cigarette smoking. Addictive Behaviors 10(2): 113-126

Experienced male smokers (> 15 cigarettes daily) performed a rapid visual information processing (RVIP) task requiring the detection of sequences of 3 consecutive odd or even digits in a series presented singly on a TV screen, at a rate of 100 digits/min. Approximately 80 targets occurred every 10 min. All subjects took part in 3 test sessions: Baseline of 10 min on the RVIP task, treatment phase of 10 min smoking 1 cigarette (0.9 mg or 1.5 mg standard machine delivery of nicotine) or not smoking (NS), posttreatment phase of 20 min on the task. Before these morning sessions subjects abstained from smoking for at least 12 h. Smoking increased the number of correct detections and decreased response time compared with pre-smoking baseline and NS sessions. Analysis of vertex event-related potentials to correct detections revealed a significant reduction in P300 latency following smoking compared to NS sessions. Smoking has apparently speeded up stimulus evaluation processes in these individuals. These data are consistent with the common self-report by smokers that smoking aids concentration.
