The information can help identify a child with marked problems with auditory figure ground listening tasks, and to identify a target S/N ratio for a classroom assistive listening device.Īdminister if you want to know more about the child’s ability to listen in noise. There are three supplementary tests in each level of the SCAN-3:Īuditory Figure-Ground (AFG) at +12 dB Signal-to-Noise RatioĪdminister if the child does not pass the AFG at +8 dB screening test. See the table below for further discussion of S/N ratios.Īdministration When should I choose to use the supplementary subtests of the SCAN-3? The different S/N ratios can help identify the optimal S/N ratio for a child to understand speech and can guide the examiner to make recommendations for classroom modification including assistive listening devices. We included three signal-to-noise (S/N) ratios in the SCAN-3 battery to determine the progression of children’s ability to hear in noise from “easy” to “very difficult.” In fact there were four S/N ratios earlier in the revision process but standardization studies found that the +4 dB S/N ratio did not add to the results, and it was removed in order to save examiner time. Test Content Why are there 3 S/N (signal-to-noise) ratios on the SCAN-3? How do I use them? The original SCAN test, published in the 1980s, was considered just a screening measure. Further, most audiologists recognize that both SCAN-C and SCAN-A (the previous test versions) were diagnostic procedures that included four tests validated in previous studies of patients with confirmed central auditory lesions. Overall, the nine tests of the SCAN-3 test batteries include all of the behavioral measures recommended in the recent Guidelines for the Diagnosis, Treatment, and Management of children and adults with central auditory processing disorder published in 2010 by the American Academy of Audiology. The SCAN-3 diagnostic tests include standard scores with percentile ranks and confidence intervals that are important in the interpretation of test results. The criterion-referenced norms provide cut scores for determining pass/fail of the screening measures. If an examinee fails the screening tests, or if there is a referral for diagnostic testing, then the audiologist can proceed with the diagnostic portion of the test. SCAN-3 contains three screening measures that can be used to determine if the entire battery should be administered. Purpose and Use Are the SCAN-3 tests (both Children and Adolescents/Adults) screening or diagnostic tests? Tests for ADHD include gathering first-hand information about the child’s behaviors from parents, teachers and school records and having a psychologist interview and observe the child.Select a question below to see the response. Testing for APD includes hearing, language and speech assessments and cognitive testing which can show how well the child’s brain is processing information. ADHD is impairment of the brain’s “executive functioning” area found in the prefrontal lobe of the brain.Ī child suspected of having APD or ADHD should be given the appropriate tests necessary to determine if they have one disorder or both disorders. Instead, children with ADHD are hyperactive, have poor impulse control and procrastinate when given a task to complete. ![]() However, ADHD is not a central nervous system disorder but a neurodevelopmental and behavioral disorder that does not involve problems with the way the brain processes auditory information. Signs of auditory process disorder are often misdiagnosed as signs of ADHD because many symptoms of both conditions overlap. Academic difficulties particularly involving subjects that require the child to hear and interpret a teacher’s instructions.Acting upset or unsettled in noisy places.Problems following directions in school and at home.Being easily distracted, forgetful and disorganized.For example, a child with APD may confuse the meaning of the words “ball” with “wall” or “bat” with “cat”, especially when they are in environments with background noises, such as playgrounds, cafeterias and classrooms. Children with APD primarily experience difficulty interpreting speech because they are unable to recognize important differences between word sounds. Auditory processing disorder (APD) is thought to be a central nervous system dysfunction involving the way the brain processes auditory input.
