Simple reaction times in subjects with steeply sloping hearing loss: is there an alteration at the edge of the loss?
The aim of the present study was to investigate the simple reaction time (RT) performance of patients with steeply sloping sensorineural hearing loss. This kind of hearing loss has the particularity of inducing a reorganization of the primary auditory cortex (Dietrich et al, 2001), the edge frequenc...

This kind of hearing loss has the particularity of inducing a reorganization of the primary auditory cortex (Dietrich et al, 2001), the edge frequency of the loss being over-represented. It is assumed that a consequence of this plasticity could be reflected in an improvement in frequency discrimination performances around the edge of the loss (McDermott et al, 1998). In the present study we used pure tones equalized in loudness to investigate whether RT might be altered at the cut-off frequency (Fc) of the loss, or at the frequency that presented the best discrimination-limen-for-frequency (bDLF). The effect of auditory rehabilitation on RT was also studied. A great variability in RT was noted in all our subjects. Our results demonstrated that RT was unmodified at Fc or bDLF, be it before or after hearing aid fitting. However, an improvement in the correlation between RT and frequency discrimination performance was observed at three months post-rehabilitation. pubtype: Academic Journal doctype: research tables/charts Journal Article ougenre: Article language: English refInfo: holdings: @attributes: islocal: N |
