Awoman is frustrated by a person at work. instead of attacking the co‑worker who is frustrating her, she yells at her best friend. according to the frustration‑aggression hypothesis, the woman is

demonstrating displacement

Explanation:

The situation at work does not inmediatly turn into agression, but creates conditions or readiness for agression if trigerred. In the case mentioned she may most likely be unable to complain or yell at the colleague, because this would be sanctioned.

Perhaps she finds herself in a unballanced situation between him and his boss, so she would rather avoid direct confrontation.

By the time her friend meets her, she displaces the frustration from the day and yells , displacing the original negative emotions that originated this stressful into his close mate.

Of course many times discplacement occurs because a direct confrontation is not wanted or impossible.
