A quantitative and qualitative assessment of verbal short-term memory and phonological processing in 8-year-olds with a history of repetitive otitis media

Language outcome in children experiencing fluctuant hearing loss due to otitis media (OME) remains highly equivocal. In the current study, we assessed performance on highly sensitive verbal short-term memory (STM), new word learning and phonological processing tasks in 8-year-old children who had suffered from recurrent OME before the age of 3. Relative to a control group with no history of OME, we observed strictly normal performance for different STM and new word learning tasks. Performance on these tasks was also normally influenced by phonotactic, lexical and semantic variables. However, at the level of phonological processing, a small but significant decrease of performance was found in a speeded nonword identification task and a rhyme judgment task. The results of this study suggest that outcome of OME is characterized by subtle impairments at the level of perceptual-phonological analysis, but there is no significant impact on verbal STM and new word learning abilities. Learning outcomes: As a result of this activity, the participant will be able to (1) explain the outcome of recurrent OME before age 3 on later language and verbal STM development, (2) be aware of the complex relationships that link language development and verbal STM, (3) explain how fluctuant hearing loss during infancy and early childhood could affect verbal STM development and learning capacity for new phonological information, (4) describe different verbal STM measures that distinguish retention capacities for phonological and lexico-semantic information, and (5) explain the influence of phonotactic frequency on nonword processing in language and verbal STM tasks.
