Operant conditioning is a foundational concept in modern dog training, yet its depth and complexity are often under-appreciated. This article delves into its historical development, its relationship with classical conditioning, and its crucial role in behaviour modification.
The Origins of Operant Conditioning
While Ivan Pavlov was pioneering research into classical conditioning, psychologist Edward L. Thorndike was investigating how animals solve problems. He formulated the "Law of Effect," which states that behaviours followed by pleasant consequences are likely to be repeated, whereas those followed by unpleasant consequences are likely to diminish.
Building on Thorndike’s work, B.F. Skinner introduced the concept of operant conditioning in 1937. He argued that organisms learn responses by interacting with their environment, with behaviour being modified through its consequences. This laid the groundwork for applied behaviour analysis and modern training methodologies.
The Interplay Between Classical and Operant Conditioning
Although classical and operant conditioning are often discussed separately, they are deeply interconnected. In reality, distinguishing between the two is a simplification for analytical purposes. Both processes occur simultaneously: when we shape behaviour using operant conditioning, we also influence the learner’s emotional state through classical conditioning. This underscores the importance of considering both aspects in training.
Contingencies and the ABCs of Behaviour
For operant conditioning to occur, there must be a contingency—a causal relationship between behaviour and environmental consequences. The most fundamental form is a two-component contingency: for example, a dog sits and receives a treat, or a dog barks and another dog moves away.
In applied behaviour analysis, a more comprehensive model is the three-component contingency:
Antecedent: The cue or situation prompting the behaviour.
Behaviour: The dog’s response.
Consequence: The outcome that influences future behaviour.
For example, if a dog sees another dog too close (antecedent), barks (behaviour), and the other dog moves away (consequence), the barking behaviour is likely to be reinforced. Context plays a crucial role, as external factors can influence whether a behaviour occurs. For instance, a dog’s recall response may vary depending on environmental distractions.
The Nature of Operant Behaviour
Operant behaviour consists of voluntary actions that an organism performs in response to environmental stimuli. These behaviours are defined by their consequences, which can be classified into five categories:
Positive Reinforcement: Adding a stimulus to increase behaviour frequency (e.g., giving a treat for sitting).
Negative Reinforcement: Removing a stimulus to increase behaviour frequency (e.g., releasing pressure on a dog’s bottom when they sit).
Positive Punishment: Adding a stimulus to decrease behaviour frequency (e.g., yelling at a dog for jumping, if jumping decreases).
Negative Punishment: Removing a stimulus to decrease behaviour frequency (e.g., walking away when a puppy bites, if biting decreases).
Extinction: Eliminating reinforcement to reduce a behaviour (e.g., ignoring begging at the table to decrease the behaviour).
It is important to note that reinforcement and punishment are defined by their effects on behaviour, not by intent. Additionally, the terms "positive" and "negative" refer to the addition or removal of stimuli, not to their pleasantness.

Understanding Negative Reinforcement
One of the most misunderstood concepts in operant conditioning is negative reinforcement. It involves increasing a behaviour by removing an aversive stimulus. However, for something to be removed, it must first be introduced—this often results in a combination of positive punishment and negative reinforcement.
A classic example involves training a horse to turn using a bit. When pressure is applied to the reins, the horse experiences discomfort. As soon as the horse turns, the pressure is released. The turning behaviour is negatively reinforced (because turning removes the pressure), while the behaviour of moving forward in a straight line is positively punished (because an aversive stimulus was added when the horse failed to turn).
The Implications of Extinction
Extinction occurs when a behaviour that was previously reinforced is no longer reinforced, leading to a decrease in its occurrence. However, this process is often accompanied by an extinction burst, where the behaviour temporarily intensifies before fading. If reinforcement resumes, spontaneous recovery can occur, reinstating the behaviour. This unpredictability makes extinction a less reliable behaviour modification tool compared to reinforcement-based strategies.
The Risks of Positive Punishment
Scientific evidence strongly advises against using positive punishment as a primary training method. It carries a high risk of negative side effects, including fear, aggression, and damage to the trainer-dog relationship. Furthermore, it often fails to provide the learner with an alternative behaviour to perform, making reinforcement-based approaches more effective and ethical.
Final Thoughts
Operant conditioning is an essential framework for understanding and modifying behaviour. However, its application requires careful consideration of contingencies, reinforcement schedules, and the broader emotional impact on the learner. By leveraging reinforcement and minimising punishment, we can create ethical, effective training strategies that benefit both dogs and their trainers.
