[Intelligence in children with cleft lip and palate]

Area of Science:

• Pediatric Psychology
• Developmental Neuroscience
• Speech-Language Pathology

Context:

• Cleft lip and palate (CLP) are common congenital conditions affecting facial structure and potentially speech development.
• Previous research indicates potential cognitive variations in children with CLP, but findings are not always consistent.
• Assessing intelligence comprehensively, including both verbal and non-verbal domains, is crucial for understanding the developmental trajectory of these children.

Purpose:

• To investigate the intelligence profiles of children with cleft lip and palate.
• To compare articulation-connected (verbal) and non-articulation-connected (non-verbal) intelligence using standardized tests.
• To identify specific cognitive strengths and weaknesses in this population.

Summary:

• A study of 174 children with cleft lip and palate utilized the HAWIE and HAWIK intelligence tests.
• The group achieved an average IQ of 106.6, exceeding the normative mean of 100.
• A significant difference was observed, with non-verbal (action-part) intelligence consistently outperforming verbal (articulation-connected) intelligence across subtests.
• Qualitative analysis revealed notable strengths in verbal concept formation, verbal knowledge, and social adaptation.

Impact:

• Findings suggest that children with cleft lip and palate may possess specific cognitive strengths, particularly in non-verbal reasoning and certain verbal domains.
• This information can inform tailored educational and therapeutic interventions for children with CLP.
• Highlights the importance of using comprehensive intelligence assessments that differentiate between verbal and non-verbal abilities in this population.
