Sub-battery and Sub-test	Description
Basic motor and visual ability
Adaptive motor control test	Assesses visuomotor responsiveness using speed and accuracy measures
	Measures subject’s ability to control the rotatory movement of the CogniWheel™ in response to rotational visual stimuli
Visual salience test	Assesses basic visual processing functions
	Measures the subject’s ability to identify a wedge filled by a random pattern of black and white dots shown on an neutral (gray) background
Perceptual processing
Letter discrimination	Measures the subject’s perceptual processing of different forms, despite the addition of increasing amounts of clutter
	Discriminate real English letters from a variety of non-letter, letter-like shapes
Word discrimination	As above
	Discriminate real 3-letter words from 3-letter non-words
Shape discrimination	As above
	Discriminate a circle filled with a common shape from the rest of the display filled with other common shapes
Motion discrimination	As above
	Discriminate a circle filled with one direction of dot motion from the rest of the display filled with another direction of dot motion
Memory processing
Letter memory	Assesses memory using specialized sets of visual stimuli
	Measures the subject’s ability to recall which letter was presented as a pre-cue, and then select that letter from a display of alternative items, despite the addition of increasing amounts of clutter
	Select the correct letter of the English alphabet
Word memory	As above
	Select the correct 3-letter word
Shape memory	As above
	Select the correct shape
