I have had intimidators in my courses, especially in intro to psych courses. They may have had prior experience with the psych environment. It is important to validate these learners and getting into a competition leads to a lack of respect for the instructor - generally, other students just think the intimidator is a horses ass. So it is with professionalism and knowledge that an instructor can win over an intimidator - but also acknowledging that they DO know course content and it is up to us, the trained professional, to push them further into critical thought and analysis (Bloom's).
