%X the paper-and-pencil digit-comparison task for assessing negative priming (np) was introduced, using a referent-size-selection procedure that was demonstrated to enhance the effect. np is indicated by slower responses to recently ignored items, and proposed within the clinical-experimental framework as a major cognitive index of active suppression of distracting information, critical to executive functioning. the digit-comparison task requires circling digits of a list with digit-asterisk pairs (a baseline measure for digit-selection), and the larger of two digits in each pair of the unrelated (with different digits in successive digit-pairs) and related lists (in which the smaller digit subsequently became a target). a total of 56 students (18-38 years) participated in two experiments that explored practice effects across lists and demonstrated reliable np, i.e., slowing to complete the related list relative to the unrelated list, (f(2, 44) = 52.42, p < 0.0001). a 3rd experiment examined age-related effects. in the paper-and-pencil digit-comparison task, np was reliable for the younger (n = 8, 18-24 years) and middle-aged adults (n = 8, 31-54 years), but absent for the older group (n = 8, 68-77 years). np was also reduced with aging in a computer-implemented digit-comparison task, and preserved in a task typically used to test location-specific np, accounting for the dissociation between identity- and spatial-based suppression of distractors (rao r(3, 12) = 16.02, p < 0.0002). since the paper-and-pencil digit-comparison task can be administered easily, it can be useful for neuropsychologists seeking practical measures of np that do not require cumbersome technical equipment.
