Abstract
Integration of emotion in a virtual agent is a topic of research to depict human-like behavior in a simulated environment. For the last few decades, many researchers are working in the field of incorporating emotions in a virtual agent. In the emotion model, the behavior of an agent depends upon how the event is perceived by the agent with respect to the goal. Hence, perception of the event while considering the past experience, importance of event towards achieving goal, agent�s own capabilities and resources is an important process which directly influences the decision making and action selection. The proposed models, till date, are either too complex to adapt or are using a very few parameters to describe the event. So, in this paper, we propose an extension of perception process in an existing emotion model, EMIA and suggest the formalization of event perception and appraisal processes to make it adaptable. This has been carried out using five parameters for event description along-with fuzzy logic which makes the process more effective yet simple.

Summary
THE world presented to human being is dynamic and continuously changing which persists momentarily and gets change. Same person can perceive the same event differently, if occurred at two different moments of time. The participants from group two estimated it as more steeper than estimated by group one This shows that person with negative emotions percept the environment negatively and concludes that emotions influence our perception as well. Our emotions, which are stored as past experience in our long term memory, influences our perception of an event. Suppose a 4 yrs old kid is playing with a toy and broke it He may percept the event as good or bad, depending upon his past experience in similar event. On occurrence of an event in the external environment, it is sensed, perceived and is recorded in the perceptual memory which successively elicits the emotion and decides upon an action. What belief (good or bad) does agent has for the object involved in the event?
