Answer:
The recency effect
Step-by-step explanation:
In psychology, the recency effect refers to the tendency to remember the information that is more recently presented to us. In other words, if we are given a list of items we are more likely to remember the last items from the list.
In this example, Addie told Callum her top 10 favorite movies, however, when he tries to recall the list, he only remembers the last 2 movies she mentioned. In other words, he is remembering the last items of the list. Thus, this is most likely due to the recency effect.
