What does Digit Span on the WAIS IV measure?

WAIS Digit Span TASK. Unreviewed This subtest measures working memory, mental manipulation, cognitive flexibility, rote memory and learning, attention, and encoding.

How do you score the digit span test?

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.

What is a good Digit Span score?

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.

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 is FSIQ WAIS calculated?

The FSIQ is calculated as the sum of all scaled scores for three items on the Verbal Index and Perceptual Reasoning Index each and two items from the Working Memory Index and Processing Speed Index, usually the most ‘g’ loaded. Calculated as 25+ (sum of scaled scores) * .

What is a normal digit span?

What do digit spans measure?

The Digit Span Task is a simple behavioral measure of working memory capacity, the cognitive ability to store and manage information on a transient basis. The dependent measure, digit span, is the maximum number of digits correctly recalled.

What is a good digit span score?

Can Digit Span Forward be eliminated in WAIS-IV?

During an early research phase in the WAIS-IV project, the research directors investigated if Digit Span Forward could be eliminated (i.e., if the scaled score for Digit Span could be obtained by administering Digit Span Backward and Digit Span Sequencing only ).

What does the last column of the WAIS results mean?

The last column of the WAIS results is simply the Average, High Average, Borderline, etc. description of the test scores. The WAIS report will then break down the different subtests. The first score is the raw score, or how many the examinee got correct.

What is the highest possible score on the WAIS?

The highest possible score here is 99.9\%. The average percentile is 50\%, so a percentile of 50 would equate to an IQ of 100. This score will show how the examinee did on the test compared to other people his age. If the percentile is 60, for example, he did better than 60\% of others who were tested using the WAIS.

How does the WAIS-IV Arithmetic subtest differ from its predecessors?

Compared to its predecessors, the WAIS-IV Arithmetic subtest contains reduced verbiage in the word problems, fewer items with time bonuses, and simpler numerical calculations with more steps, reducing the pull of mathematical skill and increasing the activation of working memory.
