Purpose:
The purpose of this study was to examine fatigue associated with sustained and effortful speech-processing in children with mild to moderately severe hearing loss.
Method:
We used auditory P300 responses, subjective reports, and behavioral indices (response time, lapses of attention) to measure fatigue resulting from sustained speech-processing demands in 34 children with mild to moderately severe hearing loss (M = 10.03 years, SD = 1.93).
Results:
Compared to baseline values, children with hearing loss showed increased lapses in attention, longer reaction times, reduced P300 amplitudes, and greater reports of fatigue following the completion of the demanding speech-processing tasks.
Conclusions:
Similar to children with normal hearing, children with hearing loss demonstrate reductions in attentional processing of speech in noise following sustained speech-processing tasks-a finding consistent with the development of fatigue.
