“…The process of dividing tasks into sequential parts for training has been termed segmentation (Naylor, 1962). Several researchers have suggested that segmentation should be congruent with the task subgoal structure (Hoffman, Drucker, Morrison, & Goldberg, 1983;Knerr et al, 1986;Morrison, 1984). That is, the "parts" for part training by segmentation should be behaviors related by the fact that they share a common task subgoal.…”
