1. Effects on phonological processing skills

Aim: Examine phonological processing skills (PhPS) in children who are deaf and hard of hearing (DHH) using cochlear implants (CI) or hearing aids (HA) pre and post intervention in relation to a group of normal hearing (NH) children.

Material and Method: Tasks for lexical access, phonological processing (PhPr) and letter knowledge were administered to 48 children, 5,6 and 7 years of age. Thirty-two children used CI or HA, sixteen had NH. The study had two pre-tests and one post-test separated in time by four weeks. All children practiced ten minutes per day.

Conclusions: NH children outperformed DHH children on the majority of tasks. All children improved their accuracy in phoneme–grapheme correspondence and output phonology. Lower initial PhPS were associated with a larger phonological change. Eighteen DHH children showed specific intervention effects on PhPS, thus were boosted relatively more by phoneme–grapheme correspondence training.

2. Cognition and phonological change

Aim: Study cognitive abilities; specifically working memory and lexical access in NH and DHH children, and their correlations to phonological processing skills (PhPS) pre intervention. Analyze how cognitive abilities related to phonological change post intervention.

Material and Method: Tasks for lexical access, complex and visual working memory and Phpr were assessed pre and post intervention.

Conclusion: DHH children performed at a lower level than NH children on lexical access but equally on complex and visual working memory. Significant correlations between complex working memory and PhPS were evident in DHH children but not in NH. This suggests that DHH children recruit more cognitive resources when performing PhPr tasks. Weak initial performance on a task for phonological representations (Phrep) was the only significant predictor of phonological change in DHH children. Weak PhRep was associated with a higher age at diagnosis, higher age at implant, and shorter usage-time with CI.

Cecilia Nakeva von Mentzer
is a doctoral student in Disability Research at Linköping University and a member of HEAD Graduate School. She was born in 1968 and is a certified speech and language pathologist since 1991. Cecilia has been working with language impaired children and children with dyslexia at Uppsala University hospital since 1994. She started in the field of cochlear implants 2005 situated at the Department of Hearing Implants in Uppsala. She wrote her Master of Science at the Karolinska Institutet in Stockholm 2005. Cecilia is the originator of Pratvis (Talkwise), a computer based program for phonological training. Pratvis has served as the tool for phonological training in a work by Strömbergsson, writing her Master of Science at Lund University. 2006 the County Council in Uppsala financed a study examining if Pratvis could enhance the speech intelligibility in four children, two with normal hearing and two with cochlear implants (von Mentzer, 2008). Cecilia’s research field concerns computer based phonological training in children with hearing aids and/or cochlear implants, behavioral and neurophysiological findings (Nakeva von Mentzer et al., 2012).
