Exploring the Relationship between Learner EEG Mental Engagement and Affect
نویسندگان
چکیده
This paper studies the influence of learner’s affective states on the well established EEG-mental engagement index during a problem solving task. The electrical activity of the human brain, known as electroencephalography or EEG was registered according to an acquisition protocol in a learning environment specifically constructed for emotional elicitation. Data were gathered from 35 healthy subjects using 8 biosensors and two video cameras. The effect of learners’ emotional states on the engagement index was analyzed as well as their impact on response time variability and performance. Results showed that the engagement index was strongly influenced by emotional states and that the former can be used in an educational setting to reliably assess learner’s engagement.
