[Learning to read in children with Williams syndrome]

Area of Science:

• Neurodevelopmental disorders
• Cognitive psychology
• Linguistics

Context:

• Williams syndrome (WS) is a genetic disorder associated with relative strengths in language compared to general cognitive abilities.
• Previous research on reading in WS is limited, leading to controversy regarding their reading proficiency.
• Understanding reading abilities in WS is crucial for targeted educational and therapeutic interventions.

Purpose:

• To investigate the reading abilities of school-aged children with Williams syndrome.
• To compare their performance on specific reading tasks with a control group matched for mental age.
• To differentiate between decoding skills and lexical access in Williams syndrome.

Summary:

• Children with Williams syndrome demonstrated reading accuracy comparable to mental-age-matched controls.
• However, individuals with WS exhibited slower reading speeds for both real words and non-words.
• Naming speed tasks also revealed slower performance in the Williams syndrome group.

Impact:

• Findings suggest that children with Williams syndrome can develop effective grapheme-phoneme decoding skills.
• The study highlights potential difficulties in the development of efficient lexical reading routes in Williams syndrome.
• Results contribute to a more nuanced understanding of the cognitive profile in Williams syndrome, informing educational strategies.
