Executive Function: Comparing Bilingual and Monolingual Iranian University Students

Area of Science:

• Cognitive Neuroscience
• Psycholinguistics
• Developmental Psychology

Background:

• Bilingualism is increasingly recognized for its cognitive impacts.
• Early bilingualism may confer specific advantages in executive functions.
• Understanding these differences is crucial for educational and cognitive research.

Purpose of the Study:

• To investigate executive function (EF) differences between early bilingual (EBL) and monolingual (ML) university students.
• To compare performance on tasks measuring inhibition and working memory.
• To explore the potential benefits of early second language acquisition on cognitive abilities.

Main Methods:

• Participants: 30 male Kurdish-Persian early bilingual (EBL) and 30 male Persian monolingual (ML) university students.
• Tasks: Persian Stroop Color-Word Task (SCWT) for inhibition, Backward Digit Span Test (BDST) for working memory, Raven Standard Progressive Matrices.
• Analysis: Analysis of Variance (ANOVA) to compare group performance.

Main Results:

• EBL students showed significantly faster response times on the SCWT, indicating an inhibition advantage.
• EBL students exhibited superior performance on the BDST, suggesting enhanced working memory capacity.
• Results support the hypothesis of advantaged executive functions in early bilingual individuals.

Conclusions:

• Early bilingualism, particularly acquisition of a second language (L2) earlier in childhood, is associated with enhanced executive functions.
• These cognitive advantages may stem from the earlier onset or longer duration of bilingual experience.
• Findings contribute to the understanding of cognitive plasticity and the effects of multilingualism.
