Backward digit span test1/8/2023 ![]() ![]() ![]() In traditional DS testing digit salience is influenced by two factors. The total number of lists reported correctly is combined across forward span (FS) and backward span (BS) to produce a Wechsler total correct score. Testing ceases when the subject fails to accurately report either trial at one sequence length or when the maximal list length is reached (9 digits forward, 8 backward). Digit sequences are presented beginning with a length of two digits and two trials are presented at each increasing list length. In each case, digit span is measured for forward and reverse-order (backward) recall of digit sequences. For decades they have been a component of the widely used Wechsler memory scales (WMS) and Wechsler intelligence scales for adults and children ( Wechsler, 1997a, 1997b). Journal of Clinical Psychology, 28, 361.Measures of forward and backward digit span (DS) are among the oldest and most widely used neuropsychological tests of short-term verbal memory ( Richardson, 2007).
