good background here on auditory processing from Ruth Jurey
" In order for children to learn speech and language, and particularly to learn to read and spell, they need to be able to work with sounds in their mind. For example, they need to discern, to organize, and to remember the sounds of speech. These skills need to be strong, fluent and automatic so that the child can use them without having to think about it. Weaknesses in the brain’s ability to manage sounds can lead to speech and language disorders, and cause language-learning disabilities such as 'dyslexia.'
The Fast ForWord program takes advantage of neuroscientific research about the brain's ability to modify and develop in response to certain kinds of training. Fast ForWord strengthens the brain's ability to process sound.
Not all students are good candidates for Fast ForWord--even if they need the sort of training it provides. It is intensive, and students must be able to play specified games at the computer, with head phones on, five days a week, for several weeks. Aside from what is required of the student, it takes a strong family commitment.
I have been doing speech and language therapy for well over two decades and am convinced of the value of powerful auditory skill training--with or without the aid of a computer. Children who are not yet ready for Fast ForWord can benefit from traditional therapy and, if appropriate, complete Fast ForWord at a later time."
