Whipstitch task demands are hypothesized to be more complex than the running stitch task demands. Within each task, the “Hypothesized Abilities” column in the Scoring Tables describes the underlying abilities that are hypothesized to enable the performance observed for that score. These abilities are further hypothesized to reflect a pattern of abilities described by a mode of performance. Clinical experience suggests that abilities associated with mode 3.4 are viewed both as the person completes the three running stitches correctly, and as the person completes some actions within the whipstitch task. There are similar equivalent task demands in the whipstitch and single cordovan stitch tasks at scores of 4.2 and 4.4. The internal consistency of the hierarchy of task demands has not been tested as of this writing.
