Description

The Visual Assessment Battery (VAB) is a computerized test of discrimination and short-term memory. Seven simultaneous match-to-sample tasks, each with three systematically varied levels of difficulty, assess ability to discriminate between objects based on spatial orientation, spatial frequency, location, pattern, luminance, trajectory, and velocity. The target stimulus appears in the top half of the screen and is identical to one of two stimuli in the bottom half. A judgment is made as to which of the two bottom stimuli matches the target stimulus on top, and an answer is indicated via button press. Accuracy and response times (RTs) are recorded. The short-term memory tasks are identical to simultaneous-matching, except there is a delay between presentation of the target stimulus and of the two stimuli to be discriminated. Tasks have easy, medium, and hard conditions. Administration time for the entire VAB is approximately 30–45 min, but tasks may be administered...
