![]() ![]() Please note, we do not recommend using normative data in place of a control group. Please contact us to discuss your normative data requirements. Outcome measures cover span length (the longest sequence successfully recalled), errors, number of attempts and latency (speed of response). The number of boxes in the sequence increases from two at the start of the test, to nine at the end and the sequence and colour are varied through the test. Similarly, we have the same for the Corsi test. In the digit span test, there is also a forward and a backward version. If the first digit of number is 0, or number is 3 octal digits long, it will not be interpreted as a group match. That is, you need to start with the one you saw highlighted last. The participant must then select the boxes which changed colour in the same order that they were displayed by the computer (for the forward variant) or in the reverse order (for backward variant). In the backward test, you need to click (or touch) the rectangles in reverse order. White squares are shown on the screen, some of which briefly change colour in a variable sequence. Auditory Digit Span Test (Backward) The Auditory Digit Span (backward recall). Of the two, backward digit span provides. Spatial Span assesses visuospatial working memory capacity. A complex span task is the commonly used tool by researchers and practitioners to assess working memory capacity it does so by interleaving to-be-recalled material (e.g., digits, letters, visual patterns) with processing tasks (e.g., verbal, spatiovisual). Digit Span tests your ability to remember a sequence of numbers that appear on the screen, one at a time. Many standardised ability test batteries include two measures of working memory: forward and backward digit span. ![]()
