What is threshold theory mean in bilingualism
Threshold theory, also known as the threshold hypothesis, is a theory that suggests that there is a certain level of proficiency in a second language (L2) that individuals need to reach in order to experience cognitive and academic benefits. According to this theory, bilingual individuals need to reach a minimum threshold of language proficiency in their L2 before they can fully utilize their bilingual skills.
The threshold theory proposes that below this threshold level, individuals may face challenges in understanding and expressing themselves in the L2, which can hinder their cognitive development and academic achievement. However, once individuals surpass this threshold level, they can experience enhanced cognitive abilities, such as improved problem-solving skills, cognitive flexibility, and metalinguistic awareness.
This theory emphasizes the importance of reaching a certain level of language proficiency in order to fully benefit from bilingualism. It suggests that bilingual individuals who have not achieved this threshold level may not experience the same cognitive and academic advantages as their more proficient counterparts.
