EFFECTS OF EARLY AUDITORY DEPRIVATION UPON AUDITORY AND VISUAL INFORMATION PROCESSING

Abstract
Nine children with hearing losses and 9 normal controls used a telegraph key to reproduce temporal patterns created by an above-threshold tone or by a flashing light. The hypothesis was confirmed that early auditory deprivation is associated with a deficit in later abilities to use above-threshold auditory information. To a lesser degree, Ss[subjects] with hearing losses were inferior to normals in visual temporal pattern reproduction as well, suggesting that the effects of sensory deprivation are not limited to the deprived sensory modality.
