Abstract
The purpose of this prospective cohort investigation was to examine the effects of otitis media (OM) and its associated fluctuating conductive hearing loss on phonological and morphological perception in 2-year-olds.;It was hypothesized that experience with an inconsistent speech signal associated with the transient fluctuating hearing loss, as a result of OM, would have a negative effect on phonological and morphological perception. It was predicted that children free of OM (OM{dollar}-{dollar}) would make all target distinctions and their performance would be better than that in otitis positive (OM+) children. It was further predicted that for OM+ children morphological perception would be harder than phonological, because the former category carries additional linguistic load (e.g., plurality).;Sixteen children ages 26-28 months ({dollar}M = 26.5,\ SD = .6{dollar}) were divided into two groups, OM{dollar}-{dollar} (n = 8) and OM+ (n = 8) based on OM history in the first year on life. OM documentation was based on tympanometry, pneumatic otoscopy, and behavioral audiometry. OM{dollar}-{dollar} children were free of the disease for 4/5 visits and their PTA was 12.6 dB HL ({dollar}SD = 4.8{dollar}). OM+ children were positive for 3/5 visits and their PTA was 23 dB HL ({dollar}SD = 2.7{dollar}).;Stimuli included six monosyllabic novel word-pairs, three phonological and three morphological. Members of each pair were assigned to unfamiliar objects and differed only in the presence of final voiced or voiceless fricative (e.g., (di) / (diz), (go) / (gos)). Subjects were taught the unfamiliar words during fast mapping procedures. A bimodal preferential looking paradigm was used to test perception.;Experience with OM during the first year of life had a negative impact on phonological perception and a greater effect on morphological perception. OM{dollar}-{dollar} children performed significantly better than OM+ children on both phonological and morphological contrasts. Furthermore, results from individual word-pair analysis showed that OM+ children performed more poorly than OM{dollar}-{dollar} children on one phonological and two morphological targets, all ending with (s). The two groups were not significantly different on final (z) targets. Within OM+ group, paired comparisons among word-pairs revealed that perception of morphological {dollar}\{lcub}{dollar}-s{dollar}\{rcub}{dollar} was more difficult than perception of phonological (s). The results were examined in terms of a synergistic relationship between the low acoustic and the high linguistic weight of (s).
