Project Details


Development and growth of selected speech perception and speech
production skills will be evaluated and compared in three separate
groups of profoundly deaf children who wear cochlear implants,
vibrotactile aids, or conventional hearing aids. A repeated-
measures design will be used in which each subject will serve as
his own control. Children in the three groups will be matched on
relevant medical, audiological, and educational variables. Each
child will be enrolled in an individualized aural (re)habilitation
program throughout the three-year study, and efforts will be made
to ensure that subjects in each group receive comparable exposure
to their sensory aids. Experiments will be aimed at assessing the
relative potential of each device to: (1) enhance suprasegmental
and segmental features of speech, (2) alter the primary modality
(acoustic vs. visual) used for the perception of speech, (3)
supplement lipreading skills, (4) increase attention to task, and
(5) aid in the production and intelligibility of the children's
speech. Results from the project are expected to facilitate early
and effective intervention for acquisition of receptive and
expressive communicative skills in deaf children, and to have
implications for selection and training strategies and the design
of sensory aids for all profoundly hearing-impaired children.
