Fairness and intentionality in children's decision-making

Abstract

Few studies have addressed the role of different aspects of the Theory of Mind (ToM) (intentionality and false belief understanding) in decision-making by adults playing strategic games where the importance of fairness is crucial. Even more interesting, this topic has been less investigated with children. The goal of this research was to explore the development of the decisional behavior along with the understanding of fairness, intentions and first- and second-order false belief understanding in children who are just acquiring those abilities. Multiple rounds of the ultimatum game with a human and a non-human partner (child/roulette wheel) were played by 177 children in the age range of 5-10 years, who also completed classic false belief tasks. Results confirm the key role of fairness sensibility across age groups and different degrees of the relevance of ToM according to the variability of children's decisional behavior (stable vs. dynamic). © 2010 Springer-Verlag.
