AUDITORY DEVELOPMENTAL SCALE: 0-6 YEARS
(A Schedule of Listening, Receptive Language & Auditory Memory Skills)
The following scale was compiled from approximately 50 existing developmental scales for children with normal hearing. Please keep in mind that the milestones in this scale represent just averages. Some children are more advanced and others will attain some of these milestones at later ages. This scale represents attainable developmental guidelines for children with impaired hearing who are being immersed within the auditory-verbal approach.
Both hard-of-hearing and deaf children must first become aware of sounds; they must then attend to those different sounds. Once a listening attitude is developed, they learn to recognize the sounds, to "know" their meaning (eg., sound-object association). Finally, they can then react appropriately to the multitude of words they hear they learn to understand our spoken language.
Knowing language and using language is not the same. Normally hearing children typically understand far more than they say. Children with hearing losses should be given that same due consideration. With that in mind, this scale on the development of audition, auditory memory, and language comprehension is offered.
