Who can benefit?

Children, adolescents and adults of a wide range can benefit from Johansen-IAS. Even younger children (3-4 years) followed successfully the program. Adults also took advantage of the therapy, although for older people the program may take longer to complete. The changes will not be that much as with younger people.

Younger children:

The Johansen-IAS therapy can help children to hear and process sounds in a better and more effective way. Children with understanding problems and difficulties in expressing themselves can benefit. The therapy can be used very good together with speech therapy.

Children in primary / secondary school:

The Johansen-IAS therapy improves the processing of incoming auditory information. Children who have difficulties in following classroom instructions often pretend not to be listening to what is said. In the meantime they try to do their utmost. They often need more time to answer a question, to fulfil a classroom task. They may have an auditory processing problem (see checklist). By following the Johansen-IAS therapy children with reading and spelling problems can easier analyse the sound structure of words. Together with special remedial education the language proficiency can increase.


Adults are less often treated by Johansen-IAS therapy. Those who followed the program mentioned that the income of auditory information has been increased. They found it easier to follow and to have a conversation in a noisy surrounding. To give a presentation for an audience can be more successful than before. This gives a better self esteem which can lead to other positive experiences.  Even reading and spelling show improvements.

The Johansen-IAS therapy is no cure-all for every problem. To guarantee the positive effects of this therapy it is very important to give extensive background information about the client. Then there can be told in what way the therapy can be helpful. It is also possible that the therapy cannot help the client because of other, more complex problems.

Children with language problems in general show good results after the treatment (look at Pilot Study BC Broekhin). Only few children with speech and language problems don’t reach the wanted result. Mostly they partially profit from it.
