Abstract

Attention is defined as a mechanism that organizes and structures the operation of the person's basic cognitive processes; it has been studied from different paradigms; among them, attentional capability is related to: the quantity of stimulus a person can attend at the same time; the intensity (concentration) of his attention to them; and, the time period that this attention can be kept. We propose an attentional capability representation for Intelligent Virtual Agents (IVAs) designed with personality and emotional features through COGNITIVA. Our agent is embodied, has goals and plans to meet by performing specific actions. The proposal simulates concentration levels and intensity on performing an action, to modify agent's sensorial channels thresholds and to limit these activities according to the activation level of the organism. The aim is to provide our agent with both more believability and natural behavior, improving the user-IVA interaction and the user's presence on the system.
