What is learning in psychology?
Learning is a lasting change in behavior or knowledge resulting from experience.
How is learning different from instincts and reflexes?
Learning requires experience and change, while instincts and reflexes are innate and do not require learning.
What part of the brain controls most reflexes?
The spinal cord and brainstem.
What is a reflex?
A reflex is an automatic, involuntary response to a specific stimulus.
What is an instinct?
An instinct is an inherited, species-specific behavior that increases survival chances.
What are the two main types of learning?
Associative and non-associative learning.
What is habituation?
Decreased response to a repeated, benign stimulus over time.
What is sensitization?
Increased response to a repeated, intense stimulus.
Who discovered classical conditioning?
Ivan Pavlov.
What is an unconditioned stimulus (US)?
A stimulus that naturally and automatically triggers a response (e.g., food causing salivation).
What is an unconditioned response (UR)?
An automatic, unlearned reaction to a stimulus (e.g., salivating at food).
What is a conditioned stimulus (CS)?
A previously neutral stimulus that, after association with the US, triggers a conditioned response.
What is a conditioned response (CR)?
A learned response to a previously neutral stimulus.
What is second-order conditioning?
When a new neutral stimulus becomes a CS by being paired with an existing CS.
What is acquisition in classical conditioning?
The phase where the NS is paired with the US and becomes a CS.
What is extinction in classical conditioning?
The weakening of a CR when the CS is presented without the US.
What is spontaneous recovery?
The reappearance of a CR after a rest period following extinction.
What is stimulus generalization?
The tendency to respond to stimuli that are similar to the original CS.
What is stimulus discrimination?
The ability to distinguish between the CS and other irrelevant stimuli.
What is the principle of preparedness in learning?
Some associations are learned more easily due to evolutionary predispositions.
What is the Rescorla-Wagner model?
A model suggesting learning occurs when the US is unexpected; it involves CS-US association strength.
What is blocking in classical conditioning?
When a second CS fails to be learned because the first CS already predicts the US effectively.
How is addiction explained using classical conditioning?
Environmental cues become CS that trigger drug cravings (CR) after being paired with drug use (US).
What is the effect of conditioning on immune responses?
Stimuli like flavored drinks paired with immunosuppressants can cause conditioned suppression of the immune system.
