1Chapter 7 (Central) Auditory Processing Disorders: Current Conceptualizations
The information that guides our conceptualization of (C)APD is drawn from studies in a variety of disciplines, including but not limited to auditory and cognitive neuroscience, cognitive psychology, neuropsychology, psycholinguistics, and others. As such, several denitions and theories of (C)APD have been proposed throughout the years, with the result that a great deal of controversy has existed regarding the nature of the disorder, methods of appropriate diagnosis and intervention, and even whether the disorder exists as a distinct diagnostic entity at
all (e.g., Cacace & McFarland, 2005; McFarland & Cacace, 1995). In 1996, The American Speech-Language-Hearing Association (ASHA) convened a consensus conference to elucidate these issues (ASHA, 1996). This effort was followed by other, similar conferences (e.g., Jerger & Musiek, 2000). Finally, in 2005, a technical report and position statement were set forth that form the bases for our current conceptualization of the disorder in accordance with the available evidence to date (ASHA, 2005a, 2005b).
