La toma de decisiones individuales con riesgo desde la psicología

Abstract

This work presents some of the characteristics of the studies about the decision making process in Psychology, focusing on individual decisions in a risky environment (with known probabilities). First, some historical considerations on the decision making origine are discussed and then the author focuses on the subject referring to Cognitive and Mathematical Psychology. The next point speaks briefly about the main topics related to decision making (task, the decision maker and the answer), and discusses different ways of conceiving the general aspects of the models -descriptive versus normative- and comments on the contributions of the Theory of the Expected Utility (Von Numann and Morgenstern, 1944). Stemming from the progressive psychologization of the behavioural theories about decision making with risk, the approach of Kahneman and Tversky (1979) is schematically presented, and finishes by offering an integrative view on decision making studies.
