Answer:
making an arbitrary assumption
Explanation:
Beyonce is walking down the hallway when she sees one of her professors. She smiles and waves at him; however, he does not wave in response. As a result Beyonce begins to think that her professor does not like her. Cognitive theory suggests that Beyonce's response is the result of her making an arbitrary assumption because she just gave a judgement about one of her professor not liking her by not waving back at her without her having any specific reason or rule.
