Emotional Stabilization is a gradual process that occurs in the emotion when a stimulus is processed. This process tends to set the emotion equal to the emotion normal value through the increment or diminish of the current value. When a stimulus is processed for the emotion, the emotion value changes, if no further stimulus are received for this emotion its value will be gradually affected to become equal to the emotion normal value. In order to achieve this, the model uses the EMOTION_PERSISTENCE which represents the number of iterations that should pass until increment or diminish emotion value in one (1), to make it close to the NORMAL_EMOTION_VALUE. Even when the increment or diminish is equal to one (1) when some iterations pass, on each iteration the EMOTION_VALUE should be modified in a fraction depending on the EMOTION_PERSITENCE value.

Abstract
Today, realism and coherence are highly searched qualities in agent’s behavior; but these qualities cannot be achieved completely without incorporation of emotions. This chapter shows a model for emotional representations in intelligent agents. The model is based on the cognitive appraisal theory of emotions; this theory affirms that stimuli are processed by a cognitive mechanism that determines what emotion to feel. It is also based on the Aaron Sloman’s research where positively and negatively affective states are exposed, as well as, on the theory of basic emotions. The model tries to define an emotional representation data structure for intelligent agents. It also defines the emotional behavior mechanisms when a stimulus is processed, as well as, emotional interaction mechanisms. This chapter is presented in five sections: Introduction, where the topic is presented. State-of-the-Art, where it is introduced a review of emotional studies in psychological areas, as well as, computing areas. The Model Definition section, where a detailed model structure and mechanism are introduced. A fourth section describing the future trends and researches and finally the chapter conclusions.
