Description
Turn-taking in conversation is an important feature from which users draw conclusions about the personality of an artificial character. In particular, overlapping speech and interruptions are linked to stereotypes about dominance, but also positive phenomena such as shared enthusiasm. Silence can be awkward or a sign of patient listening.
Artificial characters are used in a wide range of contexts, from obedient home assistants to antagonists in training simulations. To generate behaviors that are consistent and appropriate for the situation, a psychologically sound model is required. I have transferred the related theories to a decision-theoretic model that represents an idealized form of human reasoning by weighing the benefits against the risks.
