In APD the physical function of the inner ear is in tact, but somewhere along the line as the sound is transmitted to the brain and processed for information to act on, the signal is scrambled or misinterpreted and is acted on incorrectly. This can lead to big challenges with learning and behavior.
Because it can have similar symptoms, APD can be confused with Attention Deficit Disorders (ADD) or Pervasive Developmental Disorder (PDD). APD can also occur in addition to these or other disorders, so it is important to get a full evaluation from a qualified professional to best understand exactly what is happening with your child.
There are several different auditory skills that may be affected by processing disorders:
- Auditory Discrimination - ability to distinguish and segment words into individual sounds - key for reading and writing
- Auditory Figure-Ground Discrimination - ability to focus on important auditory information amid background noise - listening to directions in a noisy environment
- Auditory Memory - ability to recall information heard in the short term or long term - important for remembering names, and following directions.
- Auditory Sequencing - ability to understand and remember the order of words - remembering lists or sequences like phone numbers or addresses.
