A neuropsychological study was realizad using a sample of 50 children from the city of Santa Clara, all aged between seven and ten years. Of these 50 children 25 suffer from mild auditive deficiencies, and the remaining 25 suffer from retardation of psychological development. Neuropsychological deficiencies were found. They indicate that in the clildren wuith auditive deficiencies the most affected areas were the reception, storage and processing of information, while in the children who suffeer from retardation the neuropsychological damage is more evident in the planning, verifying and control of ations. The most damaged functional systems in the children with mild auiditive deficiencies were: auidiomotor coordination, visomotor coordination, attentional stability, behavior regulation. Damage that occurs in the ontogenesis of the second functional unit will also affect the third unit, but always to a lesser extent then in the clildren who suffer from retardatiuon. The authors adress various neuropsychological complications that may be useful in educative and rehabilite prcesses when dealing with students with mil auditive deficiencies.
