TEST OF AUDITORY-PERCEPTUAL SKILLS-REVISED. Designed to quickly diagnose students who may have difficulties with auditory-perceptual processing skills that are necessary for learning. Overview. Capabilities of the Auditory System. What does the auditory system do and how well does it do it?. Hearing Sensitivity. The faintest sound that can be detected by the human ear is so weak that it moves the ear drum a distance that is equivalent to . Review the anatomy of ears. Correctly order the steps of inner ear response. Explain the brain mechanism for sound localization. Draw the central auditory pathway. Understand the common audiometric/special hearing tests. What is a Central Auditory Processing Disorder (CAPD). CAPD is a disorder that affects the way the brain processes auditory information. Individuals with CAPD have normal hearing but they have trouble recognizing and interpreting auditory information. . Assessment, Diagnosis, Treatment and Controversies. Defining Auditory Processing and APD. Auditory processing . may be described as the “efficiency and effectiveness by which the central nervous system (CNS) utilizes auditory information.” (ASHA 2005). Like light, sound travels in waves and like vision, in order to hear, we first need to receive the sensory input of the waves and then convert them into neural impulses sent to, and processed by, the brain. Amy Akiba, Elijah Balancio, Marissa Martinez, & Keala Sheets. What is APD?. History. Helmer . Mykleburst. (1954) was the first to note the symptoms of APD. He was the first to characterize symptoms. Since the time APD symptoms were first articulated, APD has not been properly, nor clearly defined because it is difficult to diagnose. Many researchers have found contradicting information on what defines the disorder. For now, APD is categorized into three types known as: Secondary APD, Acquired APD, and Developmental APD. .
