Exploring the relationship between learner EEG mental engagement and affect

Abstract

This paper studies the influence of learner's affective states on the 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 was 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. © 2010 Springer-Verlag.
