Reinforcement

The concept of reinforcement is one of the most important and utilized principles in applied behavior analysis (ABA)

Reinforcement is anything that comes after a behavior (consequence), that increases the likelihood that there will be an increase in the future probability or frequency of that behavior

You will know that reinforcement has occurred when behavior increases because of a consequence of either adding something to the environment (positive reinforcement) or removing something  from the environment (negative reinforcement)

*Reinforcements are identified through a process called a Preference Assessment
