her personal disposition , unaware

Explanation:

               The term "fundamental attribution error" in psychology is defined as our perception towards some one behavior as their natural behavior on the grounds of their internal factors or their personality. They fail to recognize the  effect of external factors such as situations and mood.

              They believe the person is behaving according to their personal disposition or behavior rather than the external situations or other person's influences.

              Thus students who are unaware to the concept of fundamental attribution error assumes the subject's behavior is her personal disposition and not because of the external factor.

Thus the answer is --  her personal disposition , unaware
