Digit span testing is a measure of memory span which is the number of items, usually words or numbers, that a person can retain and recall. Where numbers are used it is also known as digit span, and the test is called digit repetition.
Participants are presented. with a series of stimuli and after a period of time are asked to recall what was just presented to. them. From previous research such as the Memory Span experiment is has been suggested that. the capacity to hold information reaches its limits at seven plus or minus two items. In order to further the previous findings it has been suggested to modify the memory span. experiment to explore the effects different types of items have on memory and the magic number. of seven. The current study explores digits and words as if the mind processes these in the same. or different ways.
