Answer: less
Explanation:
Instant rewards reinforce desired behavior. Annual raises are less effective in reinforcing behavior because there is too much time between the behavior and the reward.
When an individual is given an instant reward, this helps and motivates such individual. This is effective in reinforcing behavior. Annual raises occur typically at end of the year or beginning of the new year. Even though they are effective as well, they're less effective than instant rewards due to the time difference.
