As visual processing ability referred to word recognition and recall of words after the image has been received by the eyes, auditory processing ability refers to what happens to impulses of sound in the brain after the ears have received them. You will recall that sound is processed into understandable words in an area of the temporal lobe of the dominant hemisphere called Wernicke’s area. The level of functioning of Wernicke’s area directly impacts the auditory recognition and recall of words. Those students who have a high level of activity in Wernicke’s area have good auditory processing ability. Those who have low levels of activity in this region struggle with the verbal skills associated with spoken words and ideas. These students have difficulty remembering what was said (following oral directions), are highly susceptible to distracting noises, and find it extremely difficult to master foreign languages. As with visual imagery and word recognition and recall, auditory processing ability is independent of intelligence. Further, longitudinal research demonstrates that six out of ten people with visual processing difficulties also have auditory processing deficits.
Auditory processing includes:
- hearing differences between sounds
- replicating a particular sound
- remembering general sound patterns
- segmenting words into individual sounds
- blending parts of words together
- rhyming
Students with an auditory deficit usually have most difficulty with reading, writing, and both expressive and receptive language.
