A Computational Model of Personality

In this paper we present a computational model of personality, PIACT, which is an extension of ACT-R cognitive architecture, to consider the effect of personality factors. The personality component of PIACT is based on the trait anxiety, which is a facet of the neuroticism dimension of the FFM psychological model of personality. The designed model has been evaluated in two parts: First, by using the technique “Reverse-U” from cognitive science. The results of our research conformed to the psychological studies. Second, the model was evaluated in a simulated soccer environment. The results indicated a decrease in the efficiency factor of the goalkeeper because of an increase in the number of the scored goals.
