Learning Task (3D Animation)

For learning and memory retention purposes, this task consisted of 3D stereoscopic animations of the biology course. To avoid participants with background knowledge regarding the animations, participants were recruited having no or very little knowledge of biology. Thus, the participants would find the biology animations to be new knowledge and during watching the content, new memory traces would be formed. In this task, three animations were shown and each animation was repeated three times. The duration of the animated contents was approximately 10 minutes and it was repeated three times; hence, approximately 30 minutes were spent in the learning task. This task was used in the first three sessions. However, in the second and third sessions, the learning contents were presented once, i.e., for 10 minutes only.

Visual Oddball Task

The purpose of this task was to check if there were any aftereffects of 3D viewing in terms of mental fatigue and/or visual discomfort. In case a participant was fatigued due to 3D viewing, the amplitude of P300 would be suppressed.41,42 The details and experimental data of this task will be discussed in Chapter 8,Visual and Cognitive Fatigue During Learning, of this book.

Recall Task

A recall task was presented that was composed of 20 multiple choice questions (MCQs) about all three animations that the participants studied during the learning task. The recall task was conducted 30 minutes after the learning task for short-term memory recall. Then in second session, after a duration of 2 months (8 weeks), the recall task was performed to check for LTM recall. This was repeated in sessions 3 and 4. An example MCQ is provided in Fig. 7.4.
