Answer:
primacy
Step-by-step explanation:
Primacy effect: It describes the propensity for any information that we learn first tend to have more value than the information being learned later.
The information that is being presented first or in the beginning has a greater impact or influence on participants than the information that is being presented later, which caused a primacy effect, even if the information is stable.
The primacy effect occurred in the given example because the participants were paying attention to the initial information that is on Corey's debate and avoid the information given later that is on Jennifer's debate.
