The production of Dutch finite verb morphology: A comparison between hearing-impaired CI children and specific language impaired children

Linguistic profiles of children with CI as compared with children with hearing or specific language impairment

“…, and 27% in Hammer et al . ). Moreover, in the present study, 59% of the children with SLI attended special schools, whereas a larger percentage of children with SLI in the previous studies did (i.e., 65% in De Hoog et al .…”

“…Other researchers (e.g., Hammer et al . ) have hypothesized that differences in underlying causes of spoken language problems would not result in differences in the acquisition of morphosyntax but would instead lead to similar linguistic profiles. However, this hypothesis was not confirmed with research data.…”

“…Hammer et al . () studied verbal morphology in 48 children with CIs in four different age groups (aged 4;0, 5;0, 6;0 and 7;0 years), with a mean implantation range of 5–43 months. On ages 5;0 and 6;0 years, the children with CIs outperformed 38 age‐matched peers with SLI on finite verb production.…”

Feasibility of a Recasting and Auditory Bombardment Treatment With Young Cochlear Implant Users

“…Such delays often persist longer than deficits in other language domains. Hammer, Coene, Rooryck, and Govaerts (2014) suggested that fewer than 50% of cochlear implant users achieve ageappropriate use of grammatical morphology. Grammatical morphology may be difficult to acquire because these morphemes tend to add little to utterance meaning, are in the word-final position, and often consist of high-frequency consonants (e.g., /s/, /t /, /d/) that tend to be less audible than other consonants.…”

“…Given that the morphosyntax errors exhibited by children with SLI are similar to those made by cochlear implant users (Hammer et al, 2014), we hypothesized that treatment using enhanced conversational recast and auditory bombardment methods would result in increasing both elicited and spontaneous use of a treated morpheme over the intervention period. Likewise, children would show evidence that they can use the treated morpheme with untrained words.…”
