    Psychophysical studies were conducted on a heterogeneous group of 12 patients using, the Cochlear Nucleus cochlear implant. These patients became profoundly deaf early in life, prior to the full development of auditory and speech skills. The aim of the studies was to determine whether the basic hearing skills of these patients differ from those of patients who becamedeaf later in life. The mean age of, the patients at confirmation of the profound hearing loss was 22.3 months (range 6 to 45 months). The mean age of at the time of implantation as 14.8 years (range 5 to 24 years). The cause of deafness was meningitis for 7 patients, congenital Usher's syndrome for 3 patients and congenital unknown for 2 patients.
