The affective filter is a psychological filter that, for better or worse, can affect a student’s ability to learn a second language. According to the Merriam Webster Dictionary, “affective” means “referring to, arising from, or influencing feelings or emotions.”
Think of this affective filter as a wall; when it’s high, it inhibits learning. When it’s low, the students are better able to learn and acquire new information.
Some surefire ways to raise the affective filter include too much error correction, lack of self-confidence, and feelings of embarrassment or shame. Unfortunately, these are all-too-common phenomena that, when left untreated, can prevent student growth and, even worse, result in a lifetime of distress.
