Emotional variables have an effect on the failure of success in acquiring a second language. The filter can either help students to acquire a language, but it can also hinder students to acquire a language. For example when students feel stressed or self-conscious about speaking a language, then they are often scared to make mistakes and don’t use the language as much and the filter will hinder them using and acquiring the language. But when students feel confident and aren’t scared to make mistakes, the students will use the language more and will interact more with other students. In this case, the filter helps the students in acquiring the language.
