The tests were evaluated on a group of people with good hearing from various age groups. CONCLUSIONS: The presented tests are the only existing ones created for the Polish language which expand the diagnostic possibilities in the case of central auditory processing disorders. It was found that there is a right ear predominance in dichotic tests, which grows together with the patient's age. This observation can be very beneficial in practice, allowing for hearing aids to be better fitted.

Since few months the evaluation of the distinctness and discrimination of phonems of cochlear implants children are being conducted. It was found some differences between distinctness and discrimination of phonems and discrimination of words. It means that scores achieved by children in standarized words--tests do not reflect the real level of speech development of each child.
