Professor chapman is very friendly with her students, allowing them extra time on assignments and giving them the freedom to come late to class whenever they want. dr. weldon, on the other hand, is much stricter in the classroom. she does not accept late assignments, tells students "be on time or don't come to class," and at least two students got no credit on the term paper because they turned it in a day late. both professors teach with the same quality but are different in their interactions with students. when evaluation time comes, students tend to give dr. weldon far lower marks because they dislike her, not because she is a bad teacher. this is an example of the effect.

The correct answer is - This is an example of halo effect.

Explanation:

Halo effect is considered to be a cognitive bias in which we judge a person based on his behavior and character and make an impression in our mind about that person that the person is nice, good or bad.  

So it this case students have got a bad impression of Dr. Weldon because she does not accept late assignments, tells students "be on time or don't come to class," and at least two students got no credit on the term paper because they turned it in a day late.

So when evaluation time comes, students tend to give Dr. Weldon far lower marks because of the halo effect.
