To what extent does bilingualism affect children's performance on the NEPSY?

Area of Science:

• Neuropsychology
• Developmental Psychology
• Linguistics

Background:

• Neuropsychological assessments are crucial for evaluating cognitive development in children.
• Understanding the impact of bilingualism on cognitive assessments is essential for accurate diagnosis.
• Previous research indicates potential differences in cognitive performance between monolingual and bilingual individuals.

Purpose of the Study:

• To investigate the performance of bilingual children on a standardized neuropsychological assessment compared to monolingual peers.
• To determine the sensitivity of the NEPSY (a children's neuropsychological assessment) to bilingualism in a UK context.
• To examine the correlation between NEPSY scores and academic achievement in children.

Main Methods:

• Twenty-seven monolingual and 27 bilingual children aged 6–7 years were recruited.
• Participants completed core subtests of the NEPSY.
• NEPSY performance was compared between the two groups, and correlations with academic achievement were analyzed.

Main Results:

• Bilingual children scored significantly lower than monolingual children in the Language domain of the NEPSY.
• Performance in Attention/Executive Functioning, Sensorimotor, Visuospatial, and Memory domains was comparable between bilingual and monolingual children.
• The NEPSY demonstrated good correlation with academic achievement measures.

Conclusions:

• The NEPSY appears relatively insensitive to cultural factors.
• The NEPSY seems to be insensitive to the effects of bilingualism when assessing children in the United Kingdom.
• While language scores differed, overall neuropsychological functioning as measured by NEPSY was comparable, suggesting its utility in this population.
