Answer:
Thought stopping
Step-by-step explanation:
Thought stopping is a technique used in cognitive-behavioral therapy and it is used to interrupt and remove problematic thoughts.
This technique consists in using a method to stop a thought (like yelling "stop", use a band in the wrist that is to be pulled when the thought appears) and then think of a more positive or productive thought to replace it with.
In this example, Carrie has anxiety and negative opinions when interacting with men. Her therapist asks her to visualize a red light whenever this opinions arise. Her therapist is using the red light as a method to stop the negative thoughts and opinions Carrie has. Therefore, this is an example of thought stopping.
