The paper focuses on the relation between the dimension of the cognitive style "analytical-intuitive", assessed with the Cognitive Style Index (CSI) instrument, and decision-making in the Iowa Gambling Task (IGT). Our study is built on the hypothesis of somatic markers and on the study of the role of emotions in the process of decision-making in the experimental game (Iowa Gambling Task) Our research studied the relationship of cognitive style and performance (and the dynamics of change) in the experimental task on a sample of 108 participants. They were administered the electronic form of IGT and the CSI questionnaire measuring the preference for cognitive style "analytical versus intuitive". No significant difference was found in the total IGT score between intuitive and analytical participants. However, a significant difference in the character of choice selection of both groups was found. The intuitive participants chose more "safer" decks that bring less variability in potential losses. In conclusions, we have questioned the concept of "beneficial" and "unfavorable" decks In the test version used in our research, we replaced these names with the concept of "safe" and "risky" decks. The reason is that the choice of the so-called "beneficial" decks is not the best strategy in terms of total wins. Research results suggest the effect of intuition on decision-making in terms of avoiding risky choices.
