PRACTICAL APPLICATION OF THE AFFECTIVE FILTER HYPOTHESIS IN FOREIGN LANGUAGE LEARNING

Abstract

This study explores the practical application of Stephen Krashen’s Affective Filter Hypothesis in foreign language learning classrooms. The hypothesis emphasizes the crucial role of emotional factors—such as motivation, self-confidence, and anxiety—in second language acquisition (SLA). High anxiety and low self-esteem are believed to raise the affective filter, preventing comprehensible input from being effectively processed, whereas positive emotional conditions facilitate acquisition. This research employed a mixed-methods approach, combining a review of relevant literature with a quasi-experimental classroom intervention. Two intermediate English classes participated in the study: one experimental group exposed to affective filter–lowering strategies and one control group receiving traditional instruction. Data were collected through pre- and post-intervention questionnaires, comprehension tests, classroom observations, and qualitative feedback. The findings demonstrate that implementing supportive teaching strategies—such as positive reinforcement, relaxation techniques, collaborative learning, and interactive tasks—significantly reduced learners’ anxiety and improved their confidence and academic performance. The results confirm that emotional variables substantially influence language acquisition outcomes. The study concludes that lowering the affective filter through intentional pedagogical practices enhances learner engagement, increases input processing, and contributes to more effective foreign language instruction.
