EXPERIMENT DESIGN AND PROTOCOL

This chapter is a part of the experiment described in Chapter 7, 2D and 3D Educational Contents. Thus, the details of target population, inclusion criteria, exclusion criteria, sample size computation, and participants have already been provided in Chapter 7, 2D and 3D Educational Contents. Here, the experimental design tasks and the procedure, which are not covered in the previous chapter, are described.

Experiment Design

In this study, the participants were divided into two groups: one group of participants was tested with 2D learning contents while another group was tested with 3D learning contents. As mentioned in Chapter 7, 2D and 3D Educational Contents, the individual participants’ reasoning and general cognitive ability were assessed using Raven’s Advanced Progressive Matrices (RAPM) test. The RAPM task was also required while analyzing the ERP components for mental fatigue. The reason is that the relationship of ERP components and general intelligence is reported in previous studies. Hence, the RAPM data of the participants was also required in this chapter along with the learning task (watching learning animated contents with 3D or 2D display) and oddball tasks for ERP signal analysis. The RAPM and learning task is briefly touched on here, and the oddball task is described in detail.

The following is the list of the experimental tasks used in the study:

  • • Raven’s Advanced Progressive Matrices (RAPM) test
  • • 3D visualization
  • • oddball task
