Re: Auditory illusion, and Auditory Processing Disorder
Without wishing to be overly pedantic about this, I really do think you
need to define what you might mean by an "auditory illusion", to answer a
question like this one. I guess that certain 'low-level' auditory illusions
(i.e., that arise from auditory features of the cochlear, AN and brainstem
processing), if that is what they are accepted as being, might be different
in APD, e.g., the audibility of a mistuned harmonic in a complex tone.
Other 'high-level' illusions, that necessitate cortical processing, e.g.,
the tritone paradox, that presupposes the existence of an implicit form of
absolute pitch, might not be ...
You'd really need to modify alot of these illusion tasks to get them into
some form that gives you a reliable performance metric, which they may not
easily provide at the moment?

What, if any, are the relationships between 'auditory illusion', and APD
(auditory processing disorder)?
Is it that APD is diagnosed as being less prevalent? What might cause it
to be up to eight times more prevalent in adults than in children? Are
auditory illusions more prevalent in children than in adults?
Auditory Processing Disorder (APD), also known as (Central) Auditory
Processing Disorder ((C)APD) is an umbrella term for a variety of
disorders that affect the way the brain processes auditory information.
It is not a sensory (inner ear)hearing impairment; individuals with APD
usually have normal peripheral hearing ability. However, they cannot
process the information they hear in the same way as others do, which
leads to difficulties in recognizing and interpreting sounds, especially
the sounds composing speech.
APD can affect both children and adults. Approximately 2-3% of children
and 17-20% of adults have this disorder. Males are two times more likely
to be affected by the disorder than females.
