What is positive and negative reinforcement according to psychology?
Positive and Negative reinforcement are used to increase the instances of a behaviour. In terms of reinforcement, the positive and negative refer to the addition or subtraction of a stimulus. Positive reinforcement, is the addition of a stimulus in response to a behaviour (Good boy, you cleaned your room so you get an icecream). Negative reiforcement is the subtraction of an aversive stimulus (A drug addict may feel withdrawl symptoms, which are horrible. He takes drugs, which remove the aversive stimulus, thus negatively reinforcing drug-taking behaviour).
