- Rohit Kumar, H. Ai, C. Rosé. 2010. Choosing Optimal Levels of Social Interaction-Towards creating Human-like Conversational Tutors. Abstract: Recent results show that socially-capable conversational tutors can be effective support in collaborative learning situations. However, in comparison to human-level social capability, we find scope for improving the tutors both in connection with learning (performance) as well as liking (perception). In this paper, we describe work towards improving state-of-the-art conversational tutors by shrinking the gap between automated and human-level social capabilities. An experiment that explores the effect of amount of social behavior is described. Besides confirming the learning effects of sociallycapable tutors from a previous study, we report on the optimal levels of social and task interaction to improve learner performance.
