Question

Quizplus · Accepted Answer

All of the above statements contribute to a highly skilled typist's ability to type 120 words per minute. The neural circuits responsible for activating each key press become active before the preceding key press has been completed, allowing for faster and smoother typing. Different neural circuits at the lower levels of the sensorimotor hierarchy can be simultaneously active without interfering with one another, further enhancing typing speed. Finally, key presses are often chunked, meaning that groups of letters or words are typed together as a single unit, allowing for greater efficiency and speed. The suggestion in option E is not a factor in typing speed.
