Comparisons of Hearing Impairment and Socio-Cultural Disadvantage in Relation to Verbal Retardation

The Psychological, Educational and Auditory Sequelae of Early, Persistent Secretory Otitis Media

“…In one study, children with early CSOM, found to compare unfavourably with normally-hearing peers on a series of hearing and language tests, were examined again 5 yrs later. Children had caught up with peers in academic performance, with an improvement in auditory sensitivity (Hamilton & Owrid, 1974;Dalzell & Owrid, 1976). The second source of evidence comes from children with CSOM and current hearing loss (Kaplan, Fleshman, Bender, Baum & Clark, 1973;Ling, 1972;Lewis, 1976;Burgener & Mouw, 1982).…”

Learning Disabilities and Conductive Hearing Loss Involving Otitis Media

“…Among the problems noted (Ventry 1980) were inadequate conditions for hearing testing, classification of hearing loss on the basis of the poorer ear, unexplained differences in sample size, failure to report statistical tests used, and "a nearly incomprehensible presentation and treatment of the data" (p. 150). Hamilton and Owrid (1974) reported on a 1972 study by Hamilton that examined the effects of mild hearing impairments on the linguistic attainment of children from lower socioeconomic backgrounds. Unlike many of the other studies, this research investigated children with mild conductive hearing losses and children with mild sensorineural hearing losses.…”

An Inquiry into the Minimal Amount of Auditory Deprivation which Results in a Cognitive Effect in Man

“…The question is really whether or not the child will catch up with hidher age level (Ruben et al, 1982;Ruben et al, 1983). The authors pointed out that in their first study (Hamilton & Owrid, 1974) the mean performance of the control students for the linguistic and cognitive functions approximated the test norm. In the follow-up study, the mean performance of their controls was significantly below established norms for the test.…”

“…Paradise (1981) in his review of Dalzell & Owrid's 1976 article implied that there were no effects on linguistic and cognitive function in the children studied 5 years after experiencing hearing loss secondary to otitis even though they originally demonstrated linguistic and cognitive deficits (Hamilton & Owrid, 1974). Dalzell & Owrid (1976) stated that 23 children were available from the original study of 30 children (Hamilton & Owrid, 1974).…”
