![]() The results for the average longest correctly repeated string of digits over all sessions by each subject are shown in Table 1 below. The digit span length increased until there were three incorrect attempts. Each backward digit span test began with two digits and was read at a rate of one digit per second. Each trial began with instructions and a statement of understanding from the subject. The backward digit span test consisted of five trials during each session. In the study ( n n n n = 20 20 2 0 20, H 0 \text_0 H 0 start text, H, end text, start subscript, 0, end subscript = 7 7 7 7 plus/minus 2 2 2 2 ), subjects completed a backward digit span test and other memory tests administered during each of five sessions over the course of a year. The first series is three numbers, such as '3, 9, 2. The person is then told to listen carefully because you will say a series of numbers and ask him to repeat them back to you in the same order you say them. Digit Span Sequencing is the last part of the subtest, and must be administered after Digit Span Forward and Digit Span Backward. The digit span test is a way of measuring the storage capacity of a person’s working memory: A testperson is visually or auditorily exposed to a sequence of digits one after the other. A researcher wanted to challenge the limits imposed by Miller’s Law ( 7 7 7 7 plus/minus 2 2 2 2 ). The digit span test consists of telling the person that you are going to give him a short test.
