In this paper, we analyze the performance of an agent developed according to a well-accepted appraisal theory of human emotion with respect to how it modulates play in the context of a social dilemma. We ask if the agent will be capable of generating interactions that are considered to be more human than machine-like. We conduct an experiment with 117 participants and show how participants rate our agent on dimensions of human-uniqueness (which separates humans from animals) and human-nature (which separates humans from machines). We show that our appraisal theoretic agent is perceived to be more human-like than baseline models, by signi cantly improving both human-nature and human-uniqueness aspects of the intelligent agent. We also show that perception of humanness positively a ects enjoyment and cooperation in the social dilemma.

“…A recent study explored how older adults perceived the emotion expressed in the facial expression of virtual avatars in three emotional dimensions-Evaluation (valance), Potency (power/dominance), and Activity-with significant consensus reached in the first two dimensions. 10 Of those avatars implemented, natural interaction has been achieved using gestures 5 as well as verbal communication. 7 Other studies have explored how to enact intelligent reactive behavior in avatars.…”

Assistive technologies can improve the quality of life of people diagnosed with different forms of social communication disorders. We report on the design and evaluation of an affective avatar aimed at engaging the user in a social interaction with the purpose of assisting in communication therapies. A human-avatar taxonomy is proposed to assist the design of affective avatars aimed at addressing social communication disorder. The avatar was evaluated with 30 subjects to assess how effectively it conveys the desired emotion and elicits empathy from the user. Results provide evidence that users become used to the avatar after a number of interactions, and they perceive the defined behavior as being logical. The users' interactions with the avatar entail affective reactions, including the mimic emotions that users felt, and establish a preliminary ground truth about prototypic empathic interactions with avatars that is being used to train learning algorithms to support social communication disorder evaluation.
