What is learning in psychology?
A relatively permanent change in behavior or knowledge due to experience.
What is classical conditioning?
Learning that occurs when a neutral stimulus becomes associated with an unconditioned stimulus to produce a conditioned response.
Who discovered classical conditioning?
Ivan Pavlov, with experiments on dogs and salivation.
What is an unconditioned stimulus (US)?
A stimulus that naturally triggers a response without prior learning.
What is an unconditioned response (UR)?
A naturally occurring reaction to an unconditioned stimulus.
What is a conditioned stimulus (CS)?
A previously neutral stimulus that, after association with a US, triggers a conditioned response.
What is a conditioned response (CR)?
The learned response to a previously neutral stimulus.
Give an example of classical conditioning.
Pavlov: Bell (CS) + Food (US) → Salivation (CR).
What is acquisition in classical conditioning?
The initial stage of learning when the CS and US are paired.
What is extinction in classical conditioning?
The weakening of the CR when the CS is presented without the US.
What is spontaneous recovery?
The reappearance of an extinguished CR after a rest period.
What is generalization in classical conditioning?
Responding similarly to stimuli that are similar to the CS.
What is discrimination in classical conditioning?
Learning to respond only to the specific CS, not similar stimuli.
What is operant conditioning?
Learning that occurs through rewards and punishments for behavior.
Who is associated with operant conditioning?
B.F. Skinner, using the Skinner box with rats and pigeons.
What is reinforcement?
Any event that strengthens the behavior it follows.
What is positive reinforcement?
Adding a desirable stimulus to increase behavior.
What is negative reinforcement?
Removing an aversive stimulus to increase behavior.
What is punishment?
Any event that decreases the behavior it follows.
What is positive punishment?
Adding an aversive stimulus to decrease behavior.
What is negative punishment?
Removing a desirable stimulus to decrease behavior.
What is a primary reinforcer?
A stimulus that is naturally reinforcing, like food or water.
What is a secondary (conditioned) reinforcer?
A stimulus that gains reinforcing power through association with a primary reinforcer, like money.
What is a fixed-ratio schedule?
Reinforcement occurs after a set number of responses.
