Cross-Sectional Study on the Effect of Bilingualism, Age, Gender, and Family Income on Executive Function Development in a Sample of Lebanese School-Aged Children.

This study investigates executive functions (EFs) and selected developmental factors in 120 children aged 6-11 years. By examining inhibition, working memory, and cognitive flexibility, the research evaluates the potential influences of age, gender, bilingualism, and family income on these EF skills. Tests adapted to Lebanese Arabic were used to assess EFs.

Development of executive functions in Lebanese children.

The current study focused on adapting EF tests for children to the Arabic language and examine the developmental trajectories of a sample of school-aged Lebanese children in four domains of EF (inhibition, flexibility, working memory, and planning). It also focused on examining the effects of gender and parental education level on EF performance. The study population included 100 Lebanese children aged from 6 to 12-years old who were grouped and comparable for age, gender, and parental level of education.

Factors associated with motor dexterity on the grooved pegboard test in a Lebanese sample.

The Grooved Pegboard Test (GPT) is a cognitive test used to assess patients' manual dexterity, rapid visual-motor coordination and psychomotor speed. Studies have shown that performance on the GPT is associated to cognitive functions and examinee's demographics; however, none of which involved Arab populations. The present study aims to explore motor dexterity as measured by the GPT and its relationship to intellectual abilities, age, gender and education in a sample of Lebanese individuals.
