Question

​sheldon goes to the grocery store to buy a few items, and when he gets there he can remember only the last few things that he wanted to buy. "i knew i should have written everything down," he says to himself. sheldon has illustrated the _____ effect

Answer 1

The answer is recency effect. The recency effect happens when you only remember the things or events that just happened in a recent time.In this case, Sheldon is showing the recency effect because he only remembered the last part of the list that he was going to buy. If Sheldon had remembered the first part, then he is experiencing the Primary effect, which is the opposite of recency effect

Answer 2

Sheldon showed the Serial-Position effect. This effect refers to man's ability to remember a series of things may it be from the beginning or the last part of a series but missing the middle part. In Sheldon's case, he was only able to remember the last few items on his list of things that he needed to buy from the grocery store. This tendency is specifically called the recency effect because the last few items were the last things he saw right before he left for the grocery store. If things were the other way around and he only remembered the first items on his list, the it would be called Primary Effect.
