Using Electrophysiological Features in Cognitive Tasks: An Empirical Study

Abstract

Abstract-Learners' performances in intelligent tutoring systems or e-learning environments depend on various factors such as the nature of the task presented, their cognitive and affective abilities, etc. In this paper, we focus on studying in detail the variation of these different factors and more specifically the electroencephalogram (EEG metrics) and how they differ according to a category and a type of cognitive tasks. We also studied the possibility of predicting a learner's performance using feature selection and multiple regressions. Primarily, results shows that learners' scores could be predicted using in descending order the difficulty level of the task, the type of a task, the duration of a task and the EEG workload metric by building a multiple regression model that fit our data.
