Purpose: The general purpose of the study was to examine the effects of bilingualism on cognitive processing.
Methodology: The study adopted a desktop research methodology. Desk research refers to secondary data or that which can be collected without fieldwork. Desk research is basically involved in collecting data from existing resources hence it is often considered a low cost technique as compared to field research, as the main cost is involved in executive’s time, telephone charges and directories. Thus, the study relied on already published studies, reports and statistics. This secondary data was easily accessed through the online journals and library.
Findings: The findings reveal that there exists a contextual and methodological gap relating to the effects of bilingualism on cognitive processing. Preliminary empirical review revealed that bilingualism is associated with cognitive advantages, such as enhanced attentional control, executive function, and working memory capacity. Through a review of existing literature, it was found that bilingual individuals often outperform monolinguals in cognitive tasks, supporting the Bilingual Advantage Theory. Additionally, evidence suggested that bilingualism may contribute to a slower rate of cognitive decline in older age. These findings have implications for educators, policymakers, and healthcare professionals, highlighting the potential benefits of promoting bilingual education and language preservation efforts.
Unique Contribution to Theory, Practice and Policy: The Bilingual Advantage theory, Neuroplasticity and Cognitive Reserve theory may be used to anchor future studies on bilingualism and cognitive processing. The study made significant contributions to theory, practice, and policy. It supported the Bilingual Advantage Theory by demonstrating enhanced cognitive processing abilities in bilingual individuals. Recommendations included further exploration of underlying mechanisms, tailored interventions in educational and clinical settings, and policies supporting bilingual education and language diversity. These findings and recommendations aimed to advance understanding of bilingualism's cognitive benefits, inform practice in education and healthcare, and influence policy development for promoting linguistic diversity and cognitive development.
