What is the term for the longest list of numbers that can be remembered and repeated back?

The term that refers to the longest list of numbers that can be remembered and repeated back is known as digit span. This concept is a standard way to measure working memory capacity, particularly in cognitive psychology assessments. It involves presenting a series of digits to a participant, who must then recall them in the correct order. The number of digits that can be accurately remembered typically ranges between 5 to 9 for most individuals.

Digit span highlights the limits of short-term memory and is often used in psychological testing to gauge memory function. It can serve as an indicator of cognitive abilities, such as attention and working memory. In contrast, the other terms do not specifically refer to this aspect of memory. Sequential memory refers more generally to the ability to remember sequences but does not specifically involve digits. Chunks pertain to the process of grouping information to enhance memory retention, while verbal memory focuses on the recall of words and language rather than specific numerical sequences.
