Memory and linguistic/executive functions of children with borderline intellectual functioning

Area of Science:

• Neuropsychology
• Developmental Psychology
• Child Psychology

Background:

• Borderline Intellectual Functioning (BIF) is under-researched, often grouped with Intellectual and Developmental Disabilities.
• Limited understanding of specific cognitive profiles in children with BIF.

Purpose of the Study:

• To expand the neuropsychological characterization of children with BIF.
• To analyze cognitive domains including verbal and visual memory, executive functions, and language in BIF.
• To identify specific deficits and strengths in children with BIF.

Main Methods:

• Cross-sectional comparison study of 40 children with BIF (IQ 71-84) and 40 controls.
• Utilized WISC-III, Word List, Narrative Memory, Rey Complex Figure, Face Memory, Rapid Naming (RAN/RAS), and Verbal Fluency tests.
• Assessed verbal short-term and long-term memory, visual short-term and long-term memory, naming speed, and verbal fluency.

Main Results:

• Children with BIF demonstrated deficits in verbal short-term memory, rapid naming, phonemic verbal fluency, and visual short-term memory (recognition).
• Verbal long-term memory deficits were observed in older BIF children; visual long-term memory showed no deficit.
• Verbal short-term memory emerged as a significant limitation, while visual long-term memory was a strength.

Conclusions:

• The study provides a detailed neuropsychological profile of children with BIF.
• Identified cognitive strengths and weaknesses have implications for targeted interventions and educational support.
• Highlights the need for individualized approaches considering specific cognitive profiles within BIF.
