In this study, we designed a mental workload induction experiment in the context of online learning, in which EEG and eye-tracking data of participants were synchronously recorded with the aim of investigating the association between different design principles and multimodal physiological features and then applying machine-learning technology to classify mental workload states induced by those principles. This paper systematically reviews three kinds of EEG and eye-tracking features used for mental workload classification, compares the accuracy of mental workload classification between single-modal and multimodal features, modifies the mental workload index proposed by Pope et al. to monitor the variation of mental workload in E-learning contexts, and reduces the dimensions of features for more convenient use in daily life. The results of the experiment demonstrate that (1) The classification ability of wavelet power features and eye-tracking features are better than that of entropy features in E-learning contexts; (2) Multimodal physiological data can significantly improve the accuracy of mental workload classification in E-learning contexts; and (3) Correlation-based feature selection (CFS) was employed to rank all features in descending order, and when the feature dimension is reduced to 30, the optimal average classification accuracy obtained by linear-SVM is 80.2%. Furthermore, the EEG frequency bands that are highly correlated with mental workload were analyzed, and the correlation between different brain areas and mental workload discussed. All these results lay the foundation for continuous monitoring of participants’ mental workload, making it possible to endow computers with the ability to understand mental workload in E-learning contexts, which will in turn remarkably enhance participants’ learning efficiency and performance during the pandemic, and in other circumstances necessitating online learning.

Dynamic Approach

Expectations or predictions about upcoming content play an important role during language comprehension and processing. One important aspect of recent studies of language comprehension and processing concerns the estimation of the upcoming words in a sentence or discourse. Many studies have used eye-tracking data to explore computational and cognitive models for contextual word predictions and word processing. Eye-tracking data has previously been widely explored with a view to investigating the factors that influence word prediction. However, these studies are problematic on several levels, including the stimuli, corpora, statistical tools they applied. Although various computational models have been proposed for simulating contextual word predictions, past studies usually preferred to use a single computational model. The disadvantage of this is that it often cannot give an adequate account of cognitive processing in language comprehension. To avoid these problems, this study draws upon a massive natural and coherent discourse as stimuli in collecting the data on reading time. This study trains two state-of-art computational models (surprisal and semantic (dis)similarity from word vectors by linear discriminative learning (LDL)), measuring knowledge of both the syntagmatic and paradigmatic structure of language. We develop a `dynamic approach' to compute semantic (dis)similarity. It is the first time that these two computational models have been merged. Models are evaluated using advanced statistical methods. Meanwhile, in order to test the efficiency of our approach, one recently developed cosine method of computing semantic (dis)similarity based on word vectors data adopted is used to compare with our `dynamic' approach. The two computational and fixed-effect statistical models can be used to cross-verify the findings, thus ensuring that the result is reliable. All results support that surprisal and semantic similarity are opposed in the prediction of the reading time of words although both can make good predictions. Additionally, our `dynamic' approach performs better than the popular cosine method. The findings of this study are therefore of significance with regard to acquiring a better understanding how humans process words in a real-world context and how they make predictions in language cognition and processing.
