Laws and Models of Basic Conditioning: How Our Brains Learn
Discover how scientists describe the surprising ways our brains learn through conditioning models. From classical to operant conditioning, these frameworks explain why we react the way we do and how our behaviors change over time.
Understanding the Two Types of Conditioning
Before diving deeper, it's important to understand the fundamental types of conditioning that shape our learning processes:
Classical Conditioning
This occurs when two stimuli become linked together. The classic example is Pavlov's dogs, where a bell makes a dog drool because it was previously paired with food. This type of conditioning creates automatic associations between previously unrelated stimuli.
Operant Conditioning
This happens when behavior changes because of what follows the action. For example, receiving a reward for cleaning your room increases the likelihood you'll clean again. This type of conditioning shapes voluntary behaviors through consequences.
Foundational Models of Learning
Rescorla-Wagner Model
Based on the concept of surprise. When something unexpected happens, our brain pays attention and adjusts expectations. If a bell repeatedly rings without food appearing, a dog's drooling response diminishes as surprise decreases.
Mackintosh Model
Focuses on attention. We pay more attention to signals that reliably predict important outcomes. Conversely, we learn to ignore unreliable signals, like a fire alarm that frequently goes off without cause.
Pearce-Hall Model
Emphasizes uncertainty. The more uncertain we are about when a reward will come, the more closely we monitor potential cues - similar to constantly checking your phone when waiting for an important text.
Key Models in Operant Conditioning
Thorndike's Law of Effect
Behaviors followed by pleasant consequences are more likely to be repeated, while those followed by unpleasant consequences are less likely to recur. This fundamental principle explains why rewards and punishments shape behavior.
Premack Principle
A more enjoyable activity can reinforce a less enjoyable one. For example, being allowed to play video games only after completing homework makes the homework more likely to be done.
Response Deprivation Hypothesis
When access to a normally available activity is restricted, that activity becomes more valuable as a reinforcer. Limiting screen time makes it more desirable the next day.
The Neural Science Behind Conditioning
Dopamine and Reward Prediction
Dopamine, a key neurotransmitter, activates when we predict a reward or experience something unexpectedly positive. This "reward prediction error" signals our brain to repeat behaviors that led to better-than-expected outcomes and avoid those that disappointed.
Basal Ganglia and Habit Formation
The basal ganglia act as a control system that helps form habits by deciding which actions to take based on past rewards and punishments. Over time, these decisions become automatic, like reaching for a snack when bored.
Neural Plasticity
Our brain's ability to reorganize itself by forming new neural connections allows learning to occur. This plasticity is the physical basis for how conditioning changes our behavior over time.
From Brain Science to Artificial Intelligence
1
Classical Models
Traditional conditioning theories explain how humans and animals learn through surprise, attention, and reward systems.

Neural Understanding
Modern neuroscience reveals how dopamine and brain structures implement these learning principles at a biological level.

AI Applications
These same principles now power reinforcement learning in computers and robots, creating AI systems that learn from experience.
The laws and models of conditioning shape how we learn and act throughout our lives. These fundamental principles of surprise and reward have evolved from psychological theories to the cutting edge of artificial intelligence, where they're now teaching robots to learn in ways similar to humans.
