 How Does JIAS Work?

Johansen Individualised Auditory Stimulation has been developed to stimulate the nerve pathways into and within the brain. It is directed particularly to the pathways between the right ear and the left hemisphere of the brain where information from the ears is first received and from there on down to the deeper processing areas.

Various forms of brain scanning have shown that this stimulation produces increased numbers of connectors in the form of dendrites and synapses. Connections within the language centres are therefore speeded up and made considerably more efficient with the result that the processing of language is more efficient.

Concentration and understanding improves as information is dealt with more quickly and does not swamp the child in the way it did before. More information is able to be dealt with at a time. Literacy skills (reading and spelling) are often seen to improve as the child becomes more proficient at analyzing the sound structure of words.

Johansen Individualised Auditory Stimulation is known as Hemisphere Specific Auditory Stimulation (HSAS) in the USA and Auditory Discrimination Therapy (ADT) in Scandinavia. Other forms of Sound Therapy include The Listening Programme, The Tomatis Method, AIT (Auditory Integration Training) and Samonas Sound Therapy.
