Assessment of children´s working memory using a computer game

In this paper a game for working memory assessment in children between 4 to 7 years old is introduced. We evaluate the validity of the game as an assessment tool by comparing its results on a group of pre-school children with a commercially validated working memory test. Since the correctness of an assessment highly depends on the attentional state of the subject, several algorithms have been developed to discard inattentive subjects from being evaluated. By detecting and removing the unreliable data in our experiments, we found a strong correlation between game and test measures which is a preliminary confirmation for the validity of the game as an assessment tool.
