The relationship between emotions and learning was investigated by tracking the affective states that college students experienced while interacting with AutoTutor, an intelligent tutoring system with conversational dialogue. An emotionally responsive tutor would presumably facilitate learning, but this would only occur if learner emotions can be accurately(More)
AutoTutor is an intelligent tutor that interacts smoothly with the student using natural language dialogue. This type of interaction allows us to extend the domains of tutoring. We are no longer restricted to areas like mathematics and science where interaction with the student can be limited to typing in numbers or selecting possibilities with a button.(More)
This study investigated facial features to detect the affective states (or emotions) that accompany deep-level learning of conceptual material. Videos of the participants’ faces were captured while they interacted with AutoTutor on computer literacy topics. After the tutoring session, the affective states (boredom, confusion, delight, flow, frustration, and(More)
The relationship between emotions and learning was investigated by tracking the emotions that college students experienced while learning about computer literacy with AutoTutor. AutoTutor is an animated pedagogical agent that holds a conversation in natural language, with spoken contributions by the learner. Thirty students completed a multiple-choice(More)

Histamine (10 mug/min for 3 min) infused into the brachial artery caused an increase in forearm blood flow which was reduced by mepyramine (25 mg). This effect was most marked in the first minute of the infusion. Metiamide (25 mg) had no effect on the dilatation during the infusion but caused a quicker return of flow to the resting level. The response was(More)
Computer models of tutorial dialog need to segment and classify the learner’s contributions into sequences of speech acts. The responses of the computer tutor we have developed (called AutoTutor) need to be sensitive to the speech acts of the learner’s contribution during the previous turn. We developed and tested some models that classified the speech acts(More)
