This task presents the examinee with spans of digits to help you evaluate potential deficits in attention and working memory. The measure has both a 7-item digits forward task and a 7-item digits backward task, each with its own individual score. Because the two paradigms measure distinct function, the disparate scores allow for richer interpretation than that provided by similar assessment instruments.
