Answer:
The correct answer is - This is an example of halo effect.
Step-by-step 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.
