A focus of ABA is the belief that people behave a certain way for a reason (function). The basic functions of behavior are to gain something or get away from something. In ABA we classify functions as:
A. automatic or sensory reinforcement, avoidance or escape, accessing a tangible, person or activity, and attention seeking
B. positive and negative reinforcement and positive and negative punishment
C. maintenance and generalization
D. antecedent, behavior and consequence
