title: Brief tone discrimination by children with histories of early otitis media.
abstract: Twelve children, ranging in age from 8.9 to 12.4 years, with histories of severe otitis media with effusion (OME) before age 3, were compared to age-matched cohorts in their ability to discriminate the frequency of tone pulses of 20-, 50-, and 200-msec duration. An adaptive procedure was used in combination with a two-alternative forced-choice paradigm to measure difference limens (DLs) for digitally generated 1000-Hz tones. The OME group exhibited larger DLs than the non-OME group at all three stimulus durations. These results provide tentative evidence of possible long-term effects of early OME on brief tone frequency discrimination.
