What is Learning?

An observable and measurable change in behavior due to experience.

What is Classical Conditioning?

Classical conditioning involves learning through association, where a neutral stimulus becomes associated with a meaningful stimulus to elicit a similar response.

What is Operant Conditioning?

Operant conditioning is a type of learning where behavior is controlled by consequences. Key concepts include reinforcement (increasing behavior) and punishment (decreasing behavior).

Positive vs. Negative Reinforcement

Positive reinforcement involves adding a desirable stimulus to increase a behavior. Negative reinforcement involves removing an undesirable stimulus to increase a behavior.
