Vocabulary training for children with dyslexia

Area of Science:

• Developmental Psychology
• Clinical Psychology
• Educational Psychology

Background:

• Dyslexia is a neurodevelopmental disorder impacting reading and language skills.
• Vocabulary deficits are common in individuals with dyslexia, affecting academic performance.
• Parental involvement in interventions can enhance treatment efficacy.

Purpose of the Study:

• To evaluate the effectiveness of a parent-delivered vocabulary training program for adolescents with dyslexia.
• To assess improvements in word knowledge and lexical access speed.
• To investigate generalization of vocabulary gains to untrained words.

Main Methods:

• A vocabulary training program was implemented with parents as the sole instructors for 13 adolescents with dyslexia.
• Participants received targeted vocabulary instruction.
• Word knowledge and lexical access speed were measured before and after the intervention.

Main Results:

• Significant and lasting improvements were observed in word knowledge and lexical access speed.
• When trained words aligned with the child's vocabulary age, improvements generalized to untrained words.
• Parental instruction proved effective in facilitating vocabulary development.

Conclusions:

• Parent-led vocabulary training is a viable and effective intervention for adolescents with dyslexia.
• Tailoring vocabulary training to the child's developmental level promotes broader language skill acquisition.
• This approach offers a scalable and accessible method for supporting language development in dyslexia.
