The Serial Position Effect is a psychological phenomenon that describes how people tend to remember the first and last items in a list better than those in the middle. This effect is often illustrated through experiments where participants recall words from a list, showing higher accuracy for the initial items, known as the primacy effect, and the final items, known as the recency effect. This effect highlights the importance of the order in which information is presented. It suggests that our memory is influenced by the sequence of items, making it crucial for educators and marketers to consider how they organize information to enhance recall and understanding.
