When recalling a list of terms presented in series, people will remembered the first couple of terms and the last terms but forget the terms in the middle of the list. This typical finding is termed the effect.

Serial position effect

Explanation:

The serial position effect is a psychological phenomenon related to memory that refers to the tendency of an individual to easily recall information the first items on a list, and the last items on the list, but would find it difficult to recall information of the items at the middle of the list.

For example, let's say you have a list of things you intend getting at the grocery store, and the items are listed as follows: shirt, pen, book, salad, pants, shoes, cap, bread, cream. Ordinarily, the first two items and the last two items would be easy for you to remember without looking at the list.

There are two concepts related to this, the primacy effect and the recency effect. The primacy effect refers to the tendency to recall information of the list of items at the beginning of a list than those at the middle, while the recency effect refers to the tendency to easily recall information of the items at the end of the list than those at the middle.
