Reinforcement is a consequence that strengthen behavior. To strengthen a behavior means to increase the likelihood that it will occur again in the future. You are hungry, and you said “give me cookie” and mother delivers you a cookie, so mother delivering you a cookie is a consequence to you saying “give me cookie”. And this consequence increases the likelihood that you will say “give me cookie” more in future whenever hungry. Your phone beeps and you see it’s a message from a friend. You tap to open the message and it’s a funny video that makes you laugh. In the future when the same friend contacts you, you tap to open their message. When it comes to behaviour, positive and negative do not mean good and bad. They simply mean to add and take away. Positive means adding something that you like to the environment and negative reinforcement as they remove or stop something you don’t like from happening. Both positive and negative reinforcement increase the likelihood of a response occurring in the future. The following guidelines explain how to apply reinforcement effectively when working to teach new behaviours. Make it Immediate: The longer you wait the less effective it is. Make it Social: Any interaction without the use of gifts that lets the performer know they are valued. Pair tangible with praise Make it Personal: Reinforcement must mean something to the person receiving it. Make it Earned: It must be contingent on some accomplishment.
