Electrical stimulation of the human cochlea: psychophysical and speech studies

Clark, Graeme M. (Plenum Publishing Corporation, 1981)

This report describes psychophysical and speech studies conducted on two of our post-lingually deaf patients implanted with the nature of the hearing sensations produced by the individual electrodes, and to investigate the feasibility of the transmission of speech information to higher centres by means of cadences of stimulation using on electrode at a time. Two totally deaf patients (MC1 and MC2) participated in these studies.
Experimental research into cochlear implants

Clark, Graeme M. ( 1977)

The areas of research to be discussed are studies of animal behaviour, cochlear models, multiple electrode arrays and experimental surgery.
Speech perception and the development of language in deaf children

Clark, Graeme M. ; Tong, Y. C. ( 1976)

This study has been undertaken to help determine how the perception of phonemes is important in the development of language and speech in deaf children. It is generally accepted that a pure tone audiogram is not a reliable indication of future language development, and consequently it is necessary to look for other prognostic tests. The development of these tests would be of great value not only in the prognosis but also in helping to reveal the basic underlying mechanisms in speech perception and production. This could in turn lead to a more definitive approach to the aural rehabilitation of the patient.
