Basis for Central Auditory Processing Disorder (APD)
Auditory processing disorder: The sense of hearing is very complex. There are various auditory skills that must be present in order for us to listen well. Central auditory processing disorder (CAPD) will result when any of the following skills are missing or may be defective.
- Auditory Memory – ability to receive, process, store, and recall auditory information
- Auditory Discrimination – ability to distinguish between sounds and words that are similar
- Auditory Scene Analysis – ability to separate sounds when a large mixture of sounds is present
- Auditory Figure-Ground – ability to perceive speech and particular sounds with a noisy background
- Auditory Attention – ability to maintain focus and concentration during listening tasks
- Auditory Cohesion – ability to understand meaning, inference, abstraction and intention of conversation and music.
This skill is a higher order function involving tone, facial expressions and body language often present for individuals with Asperger’s Syndrome.
- Auditory Closure – ability to fill in missing pieces of sounds and words
- Auditory Anticipation – ability to expect forthcoming sounds and words
- Auditory Temporal Processing – ability to analyze the timing and pattern of sounds
- Amplitude Perception – ability to perceive loudness or intensity of sounds
- Frequency Perception – ability to split sounds into frequency bands
- Sound Localization – ability to identify the source of sound
- Auditory Temporal Processing – ability to analyze timing and pattern of sounds
As a result of auditory distortions, which occur when, sound is perceived incorrectly, a child may demonstrate inappropriate behaviors. These auditory distortions will cause a stress response, which may lead to withdraw and become depressed, or the child may try even harder and become anxious. Also, a child may act silly and or clown around in order to obtain a sense of belonging to the group or the child may become frustrated leading to anger and aggression.

OTHER POSTS DEALING WITH APD: Students with various learning disabilities may have processing issues. We have to take information in, make sense of it, retrieve information, and then be able to relay information back. Various kinds of learning disabilities interfere with steps in this process, and the interference can happen at more than one step, especially when a person has more than one kind of difficulty. Let’s take the subject of, “Answering a question asked of you”. Most people assume that this is really simple, and thus, easy. Hah! How Hard Can It Be? Helping the awkward new student seemed like a good idea, so why did it make everything worse? Help was apparently something that is done to you and for you; I was the passive recipient for help.
They were strangely disempowering, these activities that were ostensibly for my benefit: Being the Class Project: Reflections Upon False Inclusion. Why I only appeared noncompliant and dishonest, and how I got into trouble for cheating on the reading worksheet: Failing to Cheat. What’s really going on when you ask someone a question and get that familiar, “Huh?” More importantly, what can we do to help prevent such situations? Try using Headlining. How bad does it have to get? At what point does a student’s difficulties with schoolwork demonstrate that they are having significant problems, and therefore need help? Should a student have to fail classes before someone realizes or decides that there is a problem? A, B, C, D and F. You know, ALL the students would be able to hear and see the videos and other projected notes if the classroom were just designed better: Classroom Audio/Visual: Spectacular or Just A Spectacle? Sometimes life has its funny moments. One of the problems with my Auditory Processing Disorder is that I cannot understand most song lyrics. There are only a few performers whose vocal range, diction and instrumental styles mesh to create songs that have intelligible lyrics, rather than what I usually hear, which is music with words mingled (or mangled) into the sounds of the instruments. There are some songs that are notorious for being misunderstood by lots of people; apparently entire audiences mis-heard Jimi Hendrix sing, ‘Scuse me while I kiss this guy in “Purple Haze”. The difference is that I misunderstand almost every song I’ve heard, like this one.
One of the problems we run into, sometimes unexpectedly so, is that our Assistive Devices do not “fix” the problem and make it go away. This is discouraging for the person who is newly diagnosed or newly treated for an issue, and who hoped that simply by getting some snazzy piece of equipment, everything would “be back to normal”. But it’s NOT the same. Captioned (subtitled) television isn’t just for the Deaf and hard of hearing — it’s also great for people with APD, and those for whom English is a second language: Is it CC? Those great folks at public television station WGBH in Boston, are going to work on providing captioning for all those teeny-tiny screens, our iPods, PDAs, mobile phones and other hand-helds. More Captions, w00t! One of our strengths as a couple is that we are so different from each other. It’s not that one of us must “make up for” the deficiencies of the other — that would put us into artificial dichotomies of able and disabled, forever relying upon the other in our respective rôles of an incomplete person needing the other to complete them. Rather, it’s that each of us could manage alone as competent individuals, but that together we enrich the other’s experiences of the world. Social Captioning. On the home front, we’ve recently adopted a new-to-us AT, and it took some nudging from me to get hubby to participate. Soon we were texting messages instead of talking on the phone.
We were actually communicating more information, and doing so more often. We also found that what the missives may have lacked in warm fuzzy voice tones, they made up for in reduced marital stress: Read My Clips. I hate puzzling out voice-mail! Recess: Sunday Funnies. Everyone in life has to compensate in some manner or another, because no one excels at everything. In fact, the economy depends upon people’s interdependency — earning your living doing things for others is important to the Gross National Product, is important to a town’s sense of community, and is important to a person’s self-worth from feeling useful. The problem with over-compensation is that although I have at times felt that I had vanquished my personal demons of incompetancy by having overcome various failures with landmark achievements, those successes do not mean that I cannot or will not have future problems! Running With the Red Queen. The person with APD prepares for a job interview: Welcome to the First Ring of Hell.
