To determine the test-retest reliability of the Dot Test of Visuospatial Working Memory, this task was administered to 29 patients with schizophrenia and 19 normal controls on two consecutive days. The test involved “copying” trials followed by “delay” recall trials. For “copying” trials, subjects saw a dot and then drew it on a blank sheet of paper. For “delay” trials, subjects drew the dot following a 10-, 20-, or 30-s delay. The distance between the stimulus and the drawn dot was measured for each trial.
