What it measures

Corsi Blocks Task measures spatial working memory

Outcome measures

Span

An increase in score on this outcome should be interpreted as an improvement. Higher scores are better.

How it measures

"In this task, nine identical blue squares appeared on the screen in non-overlapping random positions. A set number of blocks changed colour from blue to red in a randomly generated sequence. The cursor was locked in position until the entire sequence had been presented, at which point the participants were instructed to repeat the sequence by clicking on the blocks using the mouse and cursor. The task was repeated five times at each level of difficulty. The sequence span increased from four upwards, until the participant could no longer correctly recall the sequence, resulting in a span measure of non-verbal working memory, calculated by averaging the level of the last five correctly completed trials."
