While preparing for his first chemistry exam, jaden is studying the elements and trying to memorize their abbreviations. on test day, he is frustrated because he studied 30 elements but can only remember the abbreviation for the last 5. this tendency to remember items at the end of a list of data is called:

The correct option is: Recency effect

Explanation:

Serial position effect is a concept that describes the effect of the position of an item in a sequence on its recall accuracy. According to this theory, in a sufficiently long list of items, an individual is more likely to recall the first and the last items with greater accuracy than the middle items.

There are two types:

1. Recency effect: The items in the end of the list or series are recalled first and more accurately.

2. Primacy effect: The items in the beginning of the list or series are recalled first and more accurately.

In the given example, Jaden can only recall the abbreviation for the last 5 elements in a list of 30 elements. This tendency is known as Recency effect.
