As part of an ongoing evaluation of the Tactile Vocoder, a device that allows the acoustic waveform to be felt as a vibrational pattern on the skin, two prelingually profoundly deaf teenagers reached criterion on a 50-word vocabulary (live voice, single speaker) after 28.5 and 24.0 hours of training.

Differential effects of parental deafness and early exposure to manual communication were not observed in the cognitive and communication performance of the 38 experimental subjects. Furthermore, the Delayed sign language group performed significantly better than the early American Sign Language group on tests of speech perception and speech…

Congenitally deaf college students (N=15) attempted to generate rhymes to 50 target words. Approximately half the responses were correct rhymes with most correct responses orthographically similar to their target. About 30 percent were orthographically dissimilar to targets suggesting subjects were able to develop the sensitivity to phonological…

This study found that 5 7-year-old and 4 10-year-old prelingually hearing-impaired children displayed evidence of anticipatory coarticulation based on temporal and spectral cues, but they did so to a lesser degree than normally hearing children. (Author/JDD)

The study assessed the ability to track connected discourse by a congenitally profoundly deaf adult using an electrocutaneous vocoder and/or a vibrotactile aid in conjunction with or without lipreading and aided hearing. Overall, improvement in tracking performance occurred within and across phases of the study. (Author/DB)

This study compared American Sign Language (ASL) abilities in 36 deaf adults who acquired ASL either in early childhood or in later childhood and who were born deaf or later lost their hearing. Subjects who acquired ASL as a second language after early childhood outperformed those who acquired it as a first language at the same age. (Author/DB)

Comparison of the language development profiles of five children exposed prenatally to cocaine and associated risk factors with those of a matched nonexposed control group found that major differences between the two groups were in discourse-pragmatics, with less marked differences in syntactic development.

The speech perception performance of 10 congenitally deaf and 3 postlingually deafened children who received multichannel cochlear implants were compared at preimplant and 6-month intervals up to 2 years. The congenitally deaf children did not exhibit measurably improved performance until after 12 months or more of implant use, whereas…

Eight young children with prelingual deafness were tested with the Phonetic Level Evaluation (PLE) before receiving a cochlear implant and four times afterward. Correlations between the PLE and spontaneous speech measures were weak, suggesting that performance on the PLE has low predictive value for vowel and diphthong production during…

The study examined patterns of cognitive ability in 57 cleft lip and palate children (ages 7 to 9) with verbal deficit, but without general intellectual retardation to evaluate whether the verbal disability displayed by these children was related primarily to a specific verbal expression deficit or a more general symbolic mediation problem.…

This study, involving five experienced and trained speech language pathologists, categorized the elicited imitations of five profoundly and five severely prelingually hearing-impaired subjects using the Phonetic Level Evaluation. Failure to obtain acceptably high levels of reliability suggests that this measure may not yet be an accurate and…

This case study of a 5-year-old boy diagnosed with a specific expressive language impairment with verbal apraxia reports on chromosomal, neurological, speech/language, cognitive, and play evaluations. Evaluation found a chromosomal translocation and a severe expressive speech-language deficit but good nonverbal cognitive and communicative skills.…

Ten children, adolescents, and prelinguistically deafened adults implanted with cochlear implants exhibited substantial postoperative benefits in open-set speech perception, with some improvement in closed-set speech recognition. Results are discussed with reference to such variables as age at onset of loss, duration of profound loss, age at…
