Morphological processing influences on dyslexia in Greek-speaking children

Area of Science:

• Developmental Psychology
• Linguistics
• Educational Psychology

Background:

• Children with dyslexia often experience difficulties with language processing.
• Morphological awareness, the ability to recognize and manipulate word structures, is crucial for reading development.
• Greek, an alphabetic language with rich morphology, provides a unique context to study these challenges.

Purpose of the Study:

• To investigate the inflectional morphological awareness in Greek-speaking third-grade children with dyslexia.
• To compare the performance of dyslexic children with their typically developing peers on specific morphological tasks.
• To identify predictors of dyslexia among phonological and non-phonological oral language skills.

Main Methods:

• Administered oral experimental tasks assessing verb and noun-adjective inflectional awareness.
• Assessed phonological awareness and oral receptive vocabulary.
• Employed binary logistic regression to analyze predictive factors for dyslexia.

Main Results:

• Children with dyslexia demonstrated significant difficulties in both inflectional tasks and receptive vocabulary.
• A notable challenge for dyslexic children was the elicitation of non-past tense from past tense verbs.
• Phonological awareness emerged as a significant factor in differentiating dyslexic children from typically developing readers.

Conclusions:

• Greek-speaking children with dyslexia exhibit impaired inflectional morphological awareness and vocabulary.
• These findings underscore the importance of morphological skills instruction for enhancing reading abilities in alphabetic languages with complex morphology.
• Further research is recommended to validate these outcomes and explore intervention strategies.
