An iconic/eidetic and spatial memory task based on the famous Ayumu chimp memory test. Participants must memorize spatial positions of numbered boxes displayed briefly on a grid, then click them in numerical order.

PEBL Corsi blocks test is a visual-spatial working memory test. Subjects are asked to replicate sequences of clicks onto a set of spatially-arrayed square targets.

A test of verbal working memory where participants recall sequences of digits in forward and backward order. See spanvariants for an improved more flexible test

Working memory task that requires participants to monitor and respond when stimuli (letters/numbers and/or spatial positions) match those presented n trials back.

Visual working memory task that requires participants to detect changes in arrays of colored objects, measuring visual working memory capacity.

A comprehensive battery of 9 working memory span tasks including forward/backward digit/letter/mixed spans and ordering tasks.

Working memory task that requires participants to monitor and respond to arithmetic problems, comparing current stimuli to those presented n trials back (0-back, 1-back, or 2-back conditions).
