Creating Competitive Game Situation Using Cognitive Load

This study identifies effective interventions that can create competitive situations in a memory-based card game. The competitive condition entertains people of all ages in the game. A competitive game situation would create a flow state in players. This study focuses on Pelmanism as a memory-based game. The study identifies gimmicks to interfere with a player superior to the others with the player unnoticed to create a competitive situation in a memory game. Experimental results show that interference with higher cognitive load has a greater effect on the outcome of the game. In the experiment, the interference requiring high cognitive load degrades the correct answer rate from 33.2% to <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$\mathbf{2 4. 0 \%}$</tex>. The results of the random forest analysis indicate the importance of influencing the working memory in the memory game. It means the cognitive load on the working memory can lead to game situations that all people enjoy.
