Operant conditioning

Learning in which a dog changes its behavior because of the consequences that follow it.

Also called: operant learning, four quadrants, learning quadrants

Operant conditioning describes how consequences shape behavior. Behavior that is followed by something good tends to repeat, and behavior followed by something bad tends to fade. Trainers sort the possibilities into four quadrants: positive reinforcement, negative reinforcement, positive punishment and negative punishment. Here "positive" means adding something and "negative" means removing something.

Most everyday dog training rests on it, from teaching sit with a treat to a puppy learning that barking at the door brings attention. Dogs learn this way all the time, whether or not the owner intends it.

It differs from classical conditioning, which is about feelings and reflexes linked by association, such as a dog that gets excited at the sound of a food bag. Both kinds of learning usually happen together.
