We evaluate a wizard-of-oz spoken dialogue system that adapts to multiple user affective states in real-time: user disengagement and uncertainty. We compare this version with the prior version of our system, which only adapts to user uncertainty. Our analysis investigates how iteratively adding new affect adaptation to an existing affect-adaptive system impacts global and local performance. We find a significant increase in motivation for users who most frequently received the disengagement adaptation. Moreover, responding to disengagement breaks its negative correlations with task success and user satisfaction, reduces uncertainty levels, and reduces the likelihood of continued disengagement.
