Answer:
Sleepef effect
Step-by-step explanation:
Jamie heard about a divorce that was printed in the RAG MAG, which she does not believe is very reliable. However, over time, she forgot where she heard about the divorce. The fact that she later came to believe the story was true is known as the slepper effect.
A sleeper effect takes place in a situation when effects of a persuasive message are stronger when more time passes. In Jamies case she heard about the divorce printed in RAG MAG and forgot about it and didnt even believe it but as time passes she later believed the story to be true.
