The affective filter hypothesis suggests that emotional factors can significantly influence a learner's ability to acquire a new language. This theory, proposed by Stephen Krashen, posits that variables such as anxiety, motivation, and self-confidence can act as filters that either facilitate or hinder the language acquisition process. When learners have a low affective filter—meaning they feel secure, motivated, and confident—they are more likely to engage with the language and absorb new information effectively. Conversely, when learners are anxious or lack motivation, their affective filter is high, potentially obstructing their ability to learn.

This concept highlights the importance of creating a supportive and emotionally positive learning environment, as the emotional state of the learner can greatly impact their language learning journey. It encourages educators to acknowledge the emotional landscape of their students and to foster an atmosphere that minimizes anxiety and promotes confidence and motivation.
