In language learning, attitude can be a key factor in how a student progresses. 
Linguists studied attitude in language learning in the 1970s in Quebec, Canada, when tension was high between Anglo- and Francophones. The study found that Anglophones holding prejudices against French Canadians often did poorly in French language learning, even after studying French for years as a mandatory school subject. 
On the other hand, a learner who is keen about the target culture will be more successful in their language studies. The culturally curious students will be more receptive to the language and more open to forming relationships with native speakers.
