What is Emotional Stimulus

Handbook of Research on Synthetic Emotions and Sociable Robotics: New Applications in Affective Computing and Artificial Intelligence
Direct emotions stimuli are the result of the sensorial stimulus processing by the cognitive mechanisms. When an event occurs in the environment, sensorial stimuli are received by the agent. The cognitive mechanisms process this stimulus and generate the emotional stimulus for each one of the emotions to be affected.

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.
