Nonverbal Hearing Loss

Decent Essays

The connection between the hearing loss and memory and attention when nonverbal, visually offered cognitive tests are used is the discussion point for this study. The authors found inconsistent results regarding this relationship. Some studies implied that hearing loss is linked with decreased cognitive functioning while other studies conducted showed that individuals with hearing loss have normal cognitive abilities. This study explored the relationship between hearing loss and IQ of 30 participants with mild to severe hearing loss. The participants preformed cognitive tests of pattern recognition, sustained visual attention, and spatial working memory. These test were pulled from the Cambridge Neuropsychological Test Battery. There were regression …show more content…

This study was set forth to find out whether the association of hearing loss with subnormal cognitive testing piece persists when nonverbal cognitive tests of memory and attention are used. The authors predict normal performance of participants with hearing loss on the tests of memory and attention. From the study findings, the data indicates that diminished performance on the memory and attention tests was not associated with hearing loss. Surprisingly, those with more severe hearing loss used other resourceful strategies during the implementation on the spatial working memory subtest. This might contribute to more extensive use of working memory in the routine of daily living to overcome for the loss of speech information. In conclusion of this study, the findings showed that when testing cognitive purposes of individuals with hearing loss the use of nonverbal test is …show more content…

The regression analyses enabled the investigation of the relationship between hearing loss and performance on the CANTAB subtests while controlling for the effects of age and IQ. The performance on the subtests did show a decline with increasing age. It was decided to control the effects of age and IQ before calculating the additive predictive value of hearing loss on the subtests. Five regression analyses were preformed. The mean percentage-correct answers in the PRM subtest were 83.3% (range 58%-100%). The mean RVP-d was 2.45 (range 0.17-3.36) and the mean of RVP-b was 11.0 (range 1.3-14.9). Both were relatively high, indicating the participants made few misses and few false alarms. The present data indicates that increased hearing loss is not associated with lower pattern recognition memory; inferior sustained visual attention, or more faults made during a spatial working memory test when individuals with vary degrees of hearing loss are
