Learn how to identify auditory dysfunction, a common symptom of Sensory Processing Disorder (SPD), that causes an inability to process auditory stimuli, child behavior problems and poor listening skills.
Auditory dysfunction, along with vestibular dysfunction can affect toddler speech development and potentially lead to a language processing disorder. When you have a hard time focusing on auditory input, it can make learning words and other complex aspects of language very difficult.
A child may have overresponsivity, underresponsivity, or symptoms of sensory seeking behavior. Auditory dysfunction may coexist with signs of ADHD or cause a child to appear to have oppositional behavior because he/she doesn’t understand what you are asking him/her to do.
Children with behavior characteristics for autism may also show signs of hypersensitivity to sounds and have some auditory dysfunction as well as autism behaviors. When there are only issues related to auditory processing, the child may be later diagnosed with auditory processing disorder (APD). However, this is not typically diagnosed until 8 or 9 years of age and usually has additional symptoms of sensory modulation disorder. Here are some symptoms of auditory dysfunction:
A. Hypersensitivity to sounds
• Easily distracted by sounds not typically noticed by others such as, refrigerators, fans, heaters, humming of lights, or ticking clocks
• Behavior that is fearful of loud noises such as, blender, vacuum, lawn mower, hair dryer, or ambulance siren
• Likes quiet areas
• Gets upset when there is a loud unexpected noise
• May avoid loud public places
• Determine whether they like someone by the sound of that person’s voice
B. Hyposensitivity to sounds
• Does not respond when others are speaking
• Struggles to understand and remember what a person says
• Oblivious to certain sounds
• May be confused about where a certain sound comes from
• Self talking behavior while doing a task
• Little or no vocalizing or babbling as an infant
• Requires directions to be repeated frequently and will say “What?” often
C. Sensory Seeking auditory stimuli• Likes to be noisy
D. Difficulty developing speech and language• Problems discriminating between similar sounding words
I know that I would be very discouraged if my child had a hard time understanding language and had to wait until he was almost half way through elementary school to get assistance in helping him process auditory information properly. So, if your child has some of these symptoms listed, but is not necessarily diagnosed with SPD or APD, he/she may still benefit from occupational therapy, therapeutic listening or auditory integration therapy.
