What does the digit span subtest measure?
Digit Span (DGS) is a measure of verbal short term and working memory that can be used in two formats, Forward Digit Span and Reverse Digit Span. This is a verbal task, with stimuli presented auditorily, and responses spoken by the participant and scored automatically by the software.
What is WAIS digit span?
Digit Span also measures attention, auditory processing, and mental manipulation (Reynolds, 1997; Groth-Marnat, 2009; Sattler & Ryan, 2009). All three tasks are administered to each individual. Arithmetic items require the individual to mentally solve arithmetical word problems within a time limit.
What does digit span on the WAIS IV measure?
In the technical and interpretative manual of the WAIS- IV (Wechsler, 2008, p. 15), Digit Span Forward is described as a test involving “attention, encoding and auditory processing,” while the term WM is reserved for the Back- ward and Sequencing tasks as well as the Letter-Number Sequencing subtest.
What is a good digit span?
The average digit span for normal adults without error is seven plus or minus two. However, memory span can be expanded dramatically – in one case to 80 digits – by learning a sophisticated mnemonic system of recoding rules by which substrings of 5 to 10 digits are translated into one new chunk.
What is the digit span test used for?
The digit span test is a very short test that evaluates a person’s cognitive status. It is frequently used in hospitals and physicians’ offices in order for a clinician to quickly evaluate whether a patient’s cognitive abilities are normal or impaired.
How does the digit span work?
Digit Span tests your ability to remember a sequence of numbers that appear on the screen, one at a time. When you hear a beep, click on the numbers you just saw, in order. If you correctly recall all of the numbers, then the next sequence will be one number longer. After three mistakes, the test will end.

How does the Digit Span work?
How do you find a Digit Span?
The digit span test consists of telling the person that you are going to give him a short test. 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.
What is a normal memory span?
In a typical test of memory span, an examiner reads a list of random numbers aloud at about the rate of one number per second. At the end of a sequence, the person being tested is asked to recall the items, in order. The average memory span for normal adults is seven.
How do you score a digit span?
The item score is the sum of the scores on the two trials for that item (range=0-2). The total raw score for backwards digit span is the sum of the item scores; maximum backwards digit span total raw score is 16 points.
How do you play digit span?
How to take the Digit Span Test. A sequence of numbers appears on the screen, one at a time. At the sound of the beep, users click the numbers in the same order. The number of digits increases with correct answers, and performance is indicated by the average number of digits correctly remembered.
What are the subtests on the WAIS Intelligence Scale?
Updated structural foundations. A core battery of 10 unique subtests focuses on four specific domains of intelligence: verbal comprehension, perceptual reasoning, working memory, and processing speed. New subtests, including Visual Puzzles, Figure Weights, and Cancellation.
Which is required to get the digit span scaled score?
Digit Span Forward, Digit Span Backward, and Digit Span Sequencing all are necessary to derive the Digit Span subtest scaled score. Forgoing administration of any part of Digit Span results in a lower raw score, and therefore an artificially low subtest scaled score.
