Acquisition reversal; the effects of postlingual deafness in Yoruba.
In the first analysis of postlingual deafness language patterns in any African language, she focuses on Yoruba, a Benue-Congo language of Nigeria, Togo, and Benin.
The speechreading of adults with postlingual profound hearing impairment (persons who became hearing impaired after having established their oral language) improved when they combined speechreading with a tactile speech signal presented through a vibratory aid.
Plant and Spens studied the speech perception skills of a Swedish man with postlingual profound hearing impairment in two languages (Swedish and English) with and without vibrotactile support .
Mitochondrial DNA mutations in patients with postlingual
, non-syndromic hearing impairment.
We divided the deaf study population data into two subpopulations based on whether the hearing loss is prelingual or postlingual (whether it occurred before or after age 3 years).
Chi-square tests and analysis of variance were used to examine the univariate relationships between each variable and hearing status (categorized as normal hearing, prelingual deafness, or postlingual deafness).
Prelingual and postlingual deafness were included in the regression analyses as two dummy variables, with the general population as the reference group.
However, of the remaining 13,236 who experienced a postlingual
and postvocational hearing loss, only 625 were successfully rehabilitated that year, using RSA's status 26 criteria.
A pattern of low, negative correlations is apparent describing the relationship between pre- and postlingual
hearing loss (hearing loss before age 3 as compared to hearing loss after age 3) and subtest performance.
In human subjects who had postlingual onset of bilateral profound hearing loss, changes in cell size have been observed in the cochlear nucleus (anterior division), superior olivary nucleus (medial portion), and inferior colliculus (IC) .
Among five subjects, three were adults with postlingual deafness.
