Answer:
a) cognitive dissonance
Explanation:
In psychology, the term cognitive dissonance refers to the mental discomfort experienced by a person who holds contradictory beliefs, ideas, or values.
This discomfort is triggered by a situation in which a person's belief is contradicted by new evidence perceived by the person so the person will try to find a way to resolve the contradiction to reduce their discomfort.
In this example, <u>Jackie thought sororities were filled with snobs,</u> however during her first year in campus <u>she was approached by a sorority member who invited her to a social function</u>.
We can see that <u>Jackie's beliefs about sororities were contradicted by the new evidence she perceived when she attended the party</u>, this made her feel cognitive dissonance and h<u>er way to resolve the contradiction was to conclude that sororities do a lot of good things</u> for the community.
Thus, Jackie's change in attitude to match her behavior relates to cognitive dissonance.
