Task Paradigm. Two groups were formed; in one group, Lesson 11 was played first, followed by Lesson 6. In the other group, the sequence was reversed. At the beginning of the experiment, the participants were randomly assigned into one of two groups. (a) A one-minute video was shown to the participants to familiarize them with the main experiment. (b) Participants were fixated on a point on a gray screen for 8Â s to record their baseline EEG. (c) While recording their EEG, participants watched Lesson 6 or 11 under the NP condition. (d) They attend in a four-answer post-test. (e) Participants completed a pen-and-paper NASA-TLX questionnaire. (f) They took a ten-minute rest. (g) While recording their EEG, participants watched Lesson 6 or 11 under the P condition. (h) Again, they engaged in a four-answer post-test based on the most recent multimedia lesson they viewed. (i) Finally, they completed another NASA-TLX questionnaire for their last multimedia.
