Experimental Procedure
The experimental protocol consisted of eight main phases:
(1) introduction, (2) initial quiz, (3) instruction, (4) distractor,
(5) review, (6) distractor, (7) evaluation, and (8) survey. In
the first phase, following informed consent, the researcher
gave the participant a brief description of the experiment and
brought the participant into a sound-controlled room. Here,
the researcher familiarized the participant with the Maeda
Path Game5
, which was used later on in the experiment as
a distractor task. Each participant was given the chance to
complete one level of the game and to ask any questions regarding
playing the game. Once the participant indicated they
understood how to play the game, the researcher aided the
participant in putting on the wireless EEG headset and ensured
good connectivity. The researcher then left the room
and the participant started interacting with the computer-based
educational software, which guided the participant through
the next seven phases.
