Interestingly, experts do not suffer as much as beginners when performing complex tasks or combining multiple tasks. Because experts have extensive practice within a limited domain, the key component skills in their domain tend to be highly practiced and more automated. ① Each of these highly practiced skills then demands relatively few cognitive resources, effectively lowering the total cognitive load that experts experience. ② Thus, experts can perform complex tasks and combine multiple tasks relatively easily. ③ Furthermore, beginners are excellent at processing the tasks when the tasks are divided and isolated. ④ This is not because they necessarily have more cognitive resources than beginners; rather, because of the high level of fluency they have achieved in performing key skills, they can do more with what they have. ⑤ Beginners, on the other hand, have not achieved the same degree of fluency and automaticity in each of the component skills, and thus they struggle to combine skills that experts combine with relative ease and efficiency.
