Operant conditioning is a mechanism thought by many [[Psychology|psychologists]] to explain voluntary behavior in humans and animals.  Operant conditioning is based on the idea that behavior depends on its anticipated consequences.  A behavior that has desirable consequences tends to be repeated, whereas a behavior that has aversive consequences is unlikely to be repeated.  The consequences of behavior are referred to as ''operants''.  Operants include ''reinforcers'' and ''punishers''.  A reinforcer leads to an increase in behavior, while a punisher leads to a decrease.  Operants can be either positive or negative.  An operant is positive when a desirable or aversive consequence is added, and negative when a desirable or aversive consequence is removed.  The four types of operants thus include:

'''Positive Reinforcement''' occurs when a desired consequence leads to an increase in behavior.  This is also referred to as ''reward''.  For example, if a student achieves good grades by studying hard, he is likely to receive praise from his teachers and parents.  If the praise encourages the student to continue to study hard, it is positively reinforcing his behavior.

Some operants can be placed in multiple categories.  For example, in addition to positive punishment, requiring a student to stay after class to write an essay may also serve as negative punishment by removing the opportunity for the student to spend time with friends.
