A process-specific approach targets the same function systematically and repetitively with related tasks.
This challenging repetition is very important because it can cause an improvement in higher mental skills, such as problem solving. Repetition develops an underlying mental skill, which creates a stronger foundation for the higher mental skill that relies on that underlying skill. Therefore, the repeated targeting of mental skills allows and guides improvement in higher mental skills.
The process-specific approach of PACE uses planned, repetitive exercises that place demands on deficient mental functions. When the student masters the exercise, a more demanding exercise that targets the same mental skill is available to continue the training. Then, higher mental skills will be affected, and the final goal of a better living or work status can be reached.
