Perception des sifflantes et compréhension du pluriel chez l’enfant malentendant : étude préliminaire

Abstract : Introduction: Morphosyntactic skills are deficient in children with hearing loss. A reason could be that the comprehension of grammatical morphemes requires a fine perception of speech. This perception is difficult in a noisy environment. We hypothesize that there is a link between the perception of sibilants in noise and the oral comprehension of plurals in subject-verb agreement.
Method: This exploratory study consists of a cross-sectional study of nine normal-hearing children aged 4 to 7 years and a case study of a 5-year-old child with moderate sensorineural hearing loss. Participants performed two sibilant identification tasks in noise at 0 dB and +5 dB SNR in three vowel contexts: /a/, /i/, /u/. A plural comprehension test was proposed under 3 conditions in which plural was marked by: 1- a sibilant morpheme on the subject-verb agreement, 2- a sibilant morpheme on the verbal inflection 3- a non-sibilant morpheme on the verbal inflection.
Results: Links were found between the comprehension of morphemes and the identification of sibilants when they are used in the same vowel contexts. The hearing impaired child performed worse than the normal hearing child in both tests.
Discussion: Despite the lack of correlation between the two tasks overall, these links encourage further exploration. The case study of the hearing-impaired child shows the feasibility of a larger future study with a hearing-impaired population.
