Central Auditory Processing and Central Auditory Processing Disorder: Fundamental Questions and Considerations

The Listening in Spatialized Noise Test: An Auditory Processing Disorder Study

“…Finally, Jerger and Allen (1998) state that a lack of clarity about APD probably results from the common use of global behavioral tests without appropriate control conditions and/or manipulated variables. As noted by Wilson et al (2004), children with a supramodal deficit may perform poorly on tests of auditory processing, not because they have auditory-specific perceptual problems but because the test in question is sensitive to other processing demands-such as motivation, attention, memory, cognition, and motor skills-which are necessary to perform any behavioral task. However, by assessing a listener's performance based on difference scores, supramodal variables that may confound results are effectively cancelled out by virtue of the test protocol.…”

On the Clinical Entity in Audiology: (Central) Auditory Processing and Speech Recognition in Noise Disorders

“…On the other hand, many patients have been diagnosed with (C)APD. According to Wilson et al (2004) … despite several decades of research and despite the effort of ASHA (1996), neither clinicians nor academics can agree upon a single definition of CAP or CAPD. Academically, this can only lead to one conclusion: the rational diagnosis and rehabilitation of CAPD cannot proceed until such definitions have been agreed upon.…”

Allowing for Asymmetric Distributions When Comparing Auditory Processing Test Percentage Scores with Normative Data

“…A second limitation of a simple comparison with a cutoff score is the expression of performance purely as pass or fail (Jerger and Musiek, 2002;Wilson et al, 2004;Dillon et al, 2012). The first difficulty with this dichotomy is that it does not give any indication of the degree of skill deficit.…”
