Digit Span
Basic Characteristics
- Description
Memory span is the number of items that a person can retain and recall. Digit span, therefore, is that amount of numbers a person can retain and recall. Digit span is considered a measure of working memory although attention and comprehension also contribute to performance. Procedures for this assessment of working memory are considered standard. A list of numbers is read outloud at a rate of one number per second and then the participant is asked to recall the numbers in order. The first list will consist of three numbers and increase until the person begins to make errors. Lists of recognizeable patterns (1 3 5 7 9) should be avoided as people may remember these numbers more easily. At the end of each sequence the participant is asked to recall items in order. The average adult can remember a sequence of seven numbers, plus or minus two.
