Abstract
The present study was designed to determine the specific physiological effects of two experimental conditions, smoking and mock smoking (puffing on an unlit cigarette), with smokers and nonsmokers. Two groups (smokers versus nonsmokers) with nine subjects each (five females, four males) participated in the present study. Physiological measures included alveolar carbon monoxide (COa) levels, skin resistance, heart rate, and finger temperature across a standard session sequence. The results of the COa assessment indicated increments only in the smoking condition. Multivariate analyses of variance (MANOVA) across skin conductance, heart rate, and hand temperature were initially performed, followed by univariate analyses of variance (ANOVA) for each physiological measure. Post hoc analyses were performed using orthogonal polynomial trend analyses. A number of significant differences were found. Discussion focuses on the need for experimental controls related to cigarette smoking in psychophysiological research in general, and in hand temperature biofeedback training in particular.
