Par7cipants

48 children took part in the study. All children were between 5 – 7 years old at the ;me for tes;ng. They were matched for non-‐verbal intelligence and for sex.

1) Hearing children (n = 16) 2) Children with CI (n =17) 3) Children with HA (n = 15)

Background

The aim of the present study is to examine whether a computer-‐based phonological

interven;on program can improve phonological skills in hearing impaired and deaf children with cochlear implants and/or hearing-‐aids

Interven7on

Graphogame (Lyy;nen et al, 2009) is a computerized training program for phonemic diﬀeren;a;on. The mean of daily prac;ce was 7 min.

Behavioral Measures

Recep;ve and expressive phonological skills as well as leVer knowledge at B1, B2 and PI.

Recep;ve: Phonological representa;ons, Non word Discrimina;on and Phoneme Iden;ﬁca;on.

Expressive: Picture Naming and Non word repe;;on (NWR)

LeVer knowledge: passive and ac;ve.

Results

Interven;on revealed posi;ve eﬀects on accuracy of phoneme-‐grapheme correspondence for all children and a signiﬁcant posi;ve change on phonological

processing skills for children with weak ini;al phonological skills.

Design

The study has two pretests and one posVest (B1, B2 and PI) with 4 weeks in between. Interven;on takes place between B2 and PI. Behavioral measures are obtained at all ;me points, Event Related Poten;als at B2 and PI.
