From: Faster phonological processing and right occipito-temporal coupling in deaf adults signal poor cochlear implant outcome

Figure 1

(a) Mean performance and reaction times (% correct and RTs in milliseconds ms±s.d.) during phonological (rhyming decision on pseudo-homophones) and control (orthography decision) tasks in post-lingual deaf and normal-hearing control subjects. * Significant difference at P<0.05. (b) Phonological performance (% correct) as a function of RT (ms) in deaf (black dots with and without red-circle) and control (open diamonds) subjects. There was no statistical correlation between RT and performance in either group (the grey dotted lines represent theoretical linear regression lines). The deaf subjects who performed ≥75% correct are circled in red. The controls’ mean and median RT is represented by a vertical dotted line (similar number: 2,728 and 2,757 ms, respectively). (c) Box plots of RTs in those deaf subjects who performed ≥75% correct (in red) and controls (good performers ≥75% and whole group). These good deaf performers had significantly faster RTs than the control group. Horizontal bars represent the medians and asterisks the means. (d) Post-cochlear implant (CI) scores (speech comprehension, % correctly repeated words) in post-lingual deaf subjects as a function of RT during the phonological task. A statistical correlation shows that the fast responders became poor proficient CI users.
