Answer:
Step-by-step explanation:
Right from when we are much more younger, when you do something either bad or good there is always a reward for us and this is the concept in Psychology. When you do something good and you are giving something to compensate you for what you have done then we say that that you have been Reinforced and that concept is called Reinforcement in Psychology.
Reinforcement may be fast that is immediately or delayed. So, just as the words "immediate" and "delayed'', immediate Reinforcement is when the reward to specific action is fast and delayed Reinforcement is the reward to specific action is not fast just like the case for the students. Their reward for hardwork was good grade at the end of the semester.
