Auditory Attention and Response Set This continuous performance test assesses the child's ability to be vigilant and to maintain selective auditory attention, as well as the child's ability to shift set, to maintain a complex mental set, and to regulate responses to contrasting and matching stimuli. Having learned to respond to red in Part A, the child is then asked to shift set and respond to contrasting stimuli in Part B (When you hear red, put a yellow square in the box.)

Visual Attention This subtest measures the speed and accuracy with which a child can scan an array and locate a target. The child scans the array of pictures and marks the targets as quickly and accurately as possible. There are two arrays administered for each child. Younger children get a simple structured array and a random array. Older children take the random array and a complex array.

Statue This subtest measures inhibition and motor persistence. The child stands still in a set position over a 75 second period, inhibiting a response (eyes opening, body movement, vocalization) to distractors.

Scan C (Test for Auditiory Processing Disorders in Children-Revised)
The test is used to help sort out deficits of attention from other deficits in the auditory system. This test consists of four subtests and requires the use of head phones. The first two subtests, Filtered Words and Auditory Figure-Ground are sensitized speech tests in which the test item has been distorted in a specific way to reduce intelligibility. Problems with poor auditory closure and ability to understand speech in the presence of background noise are assessed. The last two subtests, Competing Words and Competing Sentences are dichotic listening
tasks in which different words or sentences are presented simultaneously, one to each ear.
