Decision making as a complex psychological process

This paper describes the decision-making process from a psycho- logical perspective and the importance of the analyses of its developmental trajectories. It focuses on three main points: rst, shifting from adult-centered to child-centered view; second, seeing decision making in an interpersonal and social perspective; third, similarities and differences in normative and descrip- tive approaches. Furthermore, we present two important tools of the Game Theory: the Ultimatum Game and the Dictator Game.
