Abstract
The present paper discusses the results of classic research on psychological aspects of the hearing impaired and emphasizes the fact that, today, because of the possibility of early hearing aid fitting, the psychological profile of the hearing impaired presents differential features depending upon several factors. In particular, the influence of the mother's educational attitude on the psychological reactions to prosthetic rehabilitation and its efficacy depending upon the degree of prosthesis acceptance are analyzed. Finally, the relationship between the hearing aid use and language development is considered.
