Representing Dispositions and Emotions in Simulated Combat

Emotion is an essential element of human behavior. Particularly in stressful situations such as combat, it is at least as important as rational analysis in determining a participant's behavior. Yet combat models routinely ignore this factor. DETT (Disposition, Emotion, Trigger, Tendency) is an environmentally mediated model of emotion that captures the essential features of the widely-used OCC (Ortony, Clore, Collins) model in a computationally tractable framework that can support large numbers of combatants. We motivate and describe this architecture, and report preliminary experiments that use it in simulating combat scenarios.
