What does' attitude stereotype' mean in educational psychology?

Attitude stereotype refers to a state of psychological preparation formed by individual's previous experience, which affects the acceptance and understanding of current external information. This kind of influence often occurs unconsciously. There are both positive and negative attitudes. If a teacher sincerely talks with students about eye education, but some students ignore it, refuse to accept or understand the intentions of educators from a negative perspective, they seem to have an aversion to educators for no reason. The appearance of this phenomenon is related to the attitude of students.
