A hormonal model of emotions for behavior control

This paper investigates some aspects of how emotions can aaect the behavior of an artiicial creature, a \new-born" endowed with motivational states and basic emotions. Diierent \agents" integrate this creature including agents for emotional phenomena. However, contrary to cognitive approaches, we do not tackle these directly, but go below the \agent level" and use physiological parameters to model them. Motivations drive behavior selection and organization based on the notions of arousal and sa-tiation. Emotions exert further control by sending \hor-mones" that may aaect the creature's perceptive, atten-tional, and motivational mechanisms, also modifying the intensity and execution of the selected behavior.
