Auditory Processing Disorder(APD) also referred to as Central Auditory Processing Disorder((C)APD) happens when there is a dysfunction in the auditory system. The auditory system is essentially how the ears and brain communicate with one another. Griffin (2002) describes it as “a disorder that occurs when the brain cannot process or understand correctly the sounds the ears hear, even though the ears might be functioning properly” (p. 130). There is some debate over what causes APD. There are currently two theories: (1) APD is a neurological disorder of people with known lesions of the central auditory nervous system, (2) APD can and should be understood by reference to basic auditory processing, or a bottom-up …show more content…
Stuart Rosen (2010) clarifies that “the assessment [of APD] should enable the clinician to define the cause of a listening problem and to separate hearing problems from language learning or attention deficits which may present in a similar way” (introduction, para. 2). ^There is a distinct difference between APD and an attention deficit disorder—it is the attention deficit that is hampering a student’s ability to access or use the auditory information that is coming in, while APD is likely neurological disorder. However, APD is defined as a disorder affecting auditory processing, which may occur with other cognitive and perceptual impairments. The difficulty is to disentangle …show more content…
In auditory discrimination tasks, examinees are asked to say whether two similar sounds are the same or different; a student might hear two notes close in pitch or two words with one [sound] slightly different. In temporal processing tasks, examinees hear multiple auditory stimuli in close succession; a student may be asked to detect a very brief gap between two sounds or to say whether two patterns of sounds are the same. The SCAN-3 is the newest edition of a popular test used to assess auditory processing skills, and unlike previous editions, it includes tests for diagnostic as well as screening purposes. Therefore, it is likely to be used to help diagnose APD (Test review 2009). Research shows that a proper diagnosis of APD comes from a team of professionals that include: pediatricians, otolaryngologists, audiologists, child psychiatrists, clinical psychologists, speech pathologists, and educators. However, once testing is completed, the audiologist must determine which of a number of pass–fail criteria to use in order to determine whether a diagnosis will be made (Paul,
