What condition does the Affective Filter Hypothesis state is necessary for learning a second language?

The Affective Filter Hypothesis posits that emotional factors significantly influence language acquisition. For effective second language learning, a learner needs to be in a positive emotional state, which includes feeling relaxed and motivated. When learners experience anxiety, stress, or a lack of motivation, it raises their "affective filter," which can hinder their ability to absorb and process the new language. Conversely, when they feel at ease and inspired, they become more open to input, facilitating the language learning process.

Creating a supportive and encouraging environment enhances learners' confidence and willingness to engage with new material. This aligns with best practices in language education, emphasizing the importance of emotional well-being in learning outcomes.
