Studies involving bilingual acquisition studies highlight the frequency of perception where language one is stable while language two is compelling because it experiences developmental changes. These studies question the stability of the first language compared to a context in which there is frequent activation of both languages. Multilingualism is dynamic from a person's perspective, and the life of a multilingual speaker involves access to linguistic input and interaction in both languages. According to Schmid and Kopke, coactivation is the starting point of the dynamic nature of bilingualism that can lead to bidirectional crosslingual effects. When a person applies a Jackendoffian approach to the study of human languages, the interaction between coactivation in lexical studies and cross-linguistic influence at the phonological level is not surprising.

Get an Original Essay Heritage speakers and speakers are part of the spectrum of bilingualism that ranges from bilinguals with sustained verbal access and activation in both languages ​​to bilinguals with limited access and activation in one language. The process of activation and inhibition can be more or less demanding for different people depending on the similarity in linguistic features and combinatorial rules. Due to cross-linguistic similarities, the author of the article proposes ideas for incorporating input, coactivation and logical representation into a single model. In such a model changes in input and coactivation levels can have an effect on the integration of features from different linguistic components. This integration leads to a set of interface rules in one language. This article explains more about how a person can learn two languages. The process involves borrowing from both languages ​​to create an integration that will generate a continuum of rules in the two languages ​​learned.
