Numeric Classification cultivates the ability to classify objects based on attributes of color, shape, or position, singly or in any combination. Requires the client to address frequently-changing questions and to focus on salient information. The screen displays a large grid containing designs of various shapes and colors that change every few seconds. The object is to click the mouse when the picture shows a given number of a certain design and to inhibit response at all other times. The object is to match an auditory pattern of long and short tones with a visual pattern of long and short boxes.
Patterns become longer and more complex as difficulty increases.
The object is to find target letters in a grid. Variation may be made as to the size of the grid, and as to whether the target is merely a particular letter, a letter of a particular color, or a letter above or below, or before or after some other specified letter. Target letters may be set to disappear after being chosen, or user may be required to remember which targets have already been selected.
