Central auditory processing disorder (CAPD) is a disorder that is often misunderstood because many of the behaviors and symptoms that characterize this disorder can also appear in other conditions such as difficulty learning, attention deficit hyperactivity disorder (ADHD) and even depression. Auditory processing problems can occur independently or can coexist with other non-auditory disorders. A simple questionnaire or checklist can help a speech pathologist, psychologist, or even parents screen your child, but only a certified audiologist can diagnose central auditory processing disorder. There is a series of tests that can be performed to diagnose CAPD in school-age children that includes 1) dichotic speech test, 2) low-redundancy monaural speech test, and 3) binaural (i.e., diotic) interaction test. First, Dichotic Speech Test. Dichotic refers to different signals presented simultaneously to each ear. In these tests, different linguistic stimuli are presented to both ears simultaneously or in an overlapping manner (e.g., dichotic CVs, digits, words, sentences). Then the child is asked to repeat everything he hears, testing divided attention, or to repeat everything he hears in a specific ear and this tests directed attention. The more similar and closely aligned the test items are acoustically, the more difficult the task. The dichotic digit test is one of the most commonly used tests in this category. In this test four numbers are presented to the child at the same time and the child is asked to repeat the numbers, for example the number five is presented to the right ear and at the same time the number three is presented to the left ear then the numbers nine and two presented simultaneously to... half of the paper... in the ear. Children with normal auditory processing will have no difficulty recognizing speech. An example of a tic category test is the Rapid Alternation Speech Perception Test. In this test the sentence is divided into short segments that alternate rapidly between the two ears. For example, the sentence (open the door) is divided into small segments between the two ears. The first OP segment will be presented in the first ear, then EN in the second ear, and so on. If the child only hears the segments presented to the right or left ear, he is unlikely to be able to recognize the sentence. Temporal processing tests using tonal stimuli require the listener to discriminate sound based on a sequence of auditory sounds. stimuli or temporal order in order to evaluate pattern perception and temporal functioning capabilities.
