The purpose of the current study is to measure whether delay discounting and impulsivity will differentiate between smokers and non-smokers. It is important to extend upon previous research to understand the effects of antecedent control of delay discounting and impulsivity. Research on this subject is important in developing effective interventions for impulsive behavior like smoking cigarettes. Two surveys were provided to participants: The Monetary Choice Questionnaire (MCQ-27) and the Barratt Impulsivity Scale (BIS-11). An unpaired t test was used to interpret results. Neither the MCQ-11 nor the BIS-11 had a significant difference. Further analysis was conducted comparing age differences using unpaired and paired t tests. There was significant data to support that self-ratings of impulsive behavior differed with age comparisons in the BIS-11. Smokers (ages 26-28) were more impulsive than non-smokers (ages 22-28), and smokers (ages 20-29) showed no statistical significance when compared to smokers (ages 52-68). The MCQ-27 did not show a significant difference in overt impulsive behavior.

Although many studies discuss the negative impact of it, few of them emphasize the relationship between cognitive impulsiveness and decision making in non-clinical subjects. The aim of this study is to investigate the effects of cognitive impulsiveness on decision making and explore the strategies used by participants to solve problems. For this purpose, we apply two measures of impulsivity: the self-report Barratt Impulsiveness Scale (BIS-11) and the performance based Cognitive Reflection Test (CRT).This is the first study that compares self-report impulsiveness based on BIS-11 and performance-based reflectivity measured by CRT. Moreover, due to the fact that we apply the instruments on pen and paper, it is possible to evaluate participants’ reasoning processes employed to answer CRT questions. These reasoning processes are related to the role of Executive Functions for decision making and its relationship with impulsiveness. In practical terms, we observed participants’ strategies by analyzing their calculation expressions and data organization to answer CRT questions in the paper sheet. The sample consists of 191 non-clinical adults, professionals, and undergraduate students from the fields of business, management, and accounting. Results show that cognitive impulsiveness may negatively affect performance. Moreover, there is no difference in strategies used by impulsive and non-impulsive people during a decision making, and who calculate in the paper sheet perform better. Finally, people who inhibit their immediate answers also perform better during a decision making.
