Each task in the ACLS-5 contains visual and verbal cues that match hypothesized abilities described by the Allen cognitive levels and modes. The abilities required to perform the running stitch task are associated with cognitive level 3: attention to repeating familiar actions, ability to see an immediate striking visual effect, and an awareness of simple nouns and verbs that describe actions and effects. Requesting the person to complete three stitches sets a short term goal, an ability associated with cognitive level 4. Therefore completing a specified number of stitches is not requested in this task. Similarly, when errors are made in the running stitch task, the person is not asked to compare their stitches to the sample stitches because awareness of a sample/goal is not expected in level 3. Making at least three running stitches is thought to verify that the person did not accomplish the running stitch by chance.
