Giant chess game enhances spatial navigational skills in 6-years-old children: preliminary findings.

The game of chess is a valuable extracurricular activity for children, with positive effects on their cognitive skills and academic achievements. We investigated the extent to which the Giant Chess Game (GCG) played on a giant chessboard enhances working memory in "navigational-vista" space and "reaching" space. We also assessed if the GCG enhances mental rotation skills.
