In language acquisition theory, motivation is primarily associated with which of Krashen's hypotheses?

Motivation is primarily linked to the Affective Filter Hypothesis in Krashen's theory of language acquisition. This hypothesis posits that emotional factors, such as motivation, anxiety, and self-esteem, can influence the effectiveness of language learning. A positive emotional climate can lower the affective filter, enhancing a learner's ability to acquire a new language by making them more open to receiving and processing input. Conversely, if a learner experiences high levels of anxiety or lacks motivation, the affective filter can become elevated, impeding the learning process. By addressing motivation and emotional factors, educators can create a supportive environment that fosters better language acquisition outcomes.

Other hypotheses, such as the Monitor Hypothesis, primarily deal with the role of conscious learning versus subconscious acquisition, while the Natural Order Hypothesis focuses on the predictable sequence in which language structures are acquired. The Input Hypothesis emphasizes the necessity of comprehensible input for language acquisition. While all these elements contribute to language learning, motivation is specifically addressed by the Affective Filter Hypothesis.
