Kornilova T.V., Chumakova M. A., Kornilov S.A. (2018) Tolerance and Intolerance for Uncertainty as Predictors of Decision Making and Risk Acceptance in Gaming Strategies of the Iowa Gambling Task. Psychology in Russia: State of the Art, 11 (3), 86-95



Background. This article reports on the results of an empirical study of interrelationships between indicators of decision-making strategies (indexed by the Iowa Gambling Task, IGT) and traits of tolerance and intolerance for uncertainty that capture the unity of cognitive and personality components of situational representations. 

Objective. Our study tested the hypothesis that overcoming uncertainty in decision making goes beyond cognitive representations of the task but instead is rooted in the construction of the amodal image of an uncertain situation that captures the meaning regulation of perception and action. We hypothesized that when a person is faced with multi-stage decisions, their strategies reflect the contribution of individual differences in attitudes towards uncertainty. 

Design. Using data obtained from n=60 typically developing adults (68% men; Mage = 30.58), we examined the contribution of tolerance/intolerance for uncertainty to a variety of IGT dependent variables at five different stages of the game. 

Results. The data was analyzed using the mixed linear model method as implemented in the lme4 package for R. The results indicated that tolerance for uncertainty significantly contributes to the initial level of behavioral risk, ensuring readiness for decision making under uncertainty. 

Conclusion. Tolerance for uncertainty plays an important role in early stages of orientation in an uncertain modeled game situation, and contributes to the productive development of probabilistic expectations. Intolerance for uncertainty, on the other hand, was shown to contribute to risk in decision making after trial failure, potentially limiting learning in uncertain conditions through risk aversion.
