According to Sohlberg and Mateer, the orientation of this principle is based on the Lurian concept of neurologic reorganization. These functional units were believed to be hierarchically organized and functionally integrated. The idea behind the process-specific approach is that the intense repetition of a specific neurological system facilitates and guides the reorganization of function of that system. The next principle, hierarchically organized, is based on the idea that information organized hierarchically enables the activities to be administered in a very systematic way. This principle provides a foundation for future decision-making related to treatment.
Empirical data is collected on each task measuring the individual's accuracy and speed.
Careful analysis of this data is done periodically to determine whether the treatment should be continued, modified, or terminated based on individual performance. The fifth principle, generalization of tasks, is an essential component of the process-specific approach. Anecdotal information is also used to assess generalization. Using this method, family, friends, and rehabilitation staff are asked to observe the survivor in everyday situations and report any examples of generalization taking place. I have had many students who score very high on a neuropsychological test, yet are unable to function at a level indicated by the assessment in a classroom environment.
