This important revised study highlights the construction of a strong psycholinguistic model that can explain how bilingual children develop cognitively and linguistically in a Spanish/English speaking setting. Conceptualized with the objective of developing a novel and strong psycholinguistic model, this research study explains how young children develop cognitively and linguistically when they have been immersed in a bicultural and bilingual environment. This study proves that bilingualism can be an enrichment for cognitive development, provided that cognitive cultural and linguistics variables are manipulated in a quasi-experimental rigorous research design that enables children to learn more successfully.
