Answer:
John Atkinson claimed that all of the following factors influenced one's need for achievement except the length of time needed for a goal.
Step-by-step explanation:
John Atkinson's theory is based on motivation, and what you do to accomplish your goals. The success of your goals doesn't depend on the length of time, but what you do with this time, and the efforts you undertake to accomplish what you wanted. If you work hard and put a lot of motivation on what you do, time will not affect your results.
