24-hr deprivation | 3.9### | 1.1 | 3–6 | 5.1### | 1.9 | 3–9 |
Note. Total sample size was an N of 20 (10 per group). CO levels varied as a function of deprivation in both groups; however, there were no significant group differences in CO levels. CO = carbon monoxide; IMP/SS = Impuslive-Sensation Seeking subscale; SS = Sensation Seeking group; and ZKPQ = Zuckerman-Kuhlman Personality Questionnaire.
***p<.001 (difference between Low and HIgh SS); ###p<.001 (difference between 0-hr and 24-hr deprivation).
