A conditioned response (CR) is the learned, automatic reaction triggered by a conditioned stimulus after that stimulus has been repeatedly paired with an unconditioned stimulus. In Pavlov's experiment, salivating to the bell alone is the CR.
A conditioned response (CR) is the learned reaction in classical conditioning. Before any learning happens, a neutral stimulus (like a bell) does nothing. But pair that bell with food enough times, and eventually the bell alone makes the dog salivate. That salivation to the bell is the conditioned response.
Here's the part that trips people up. The CR is often the same behavior as the unconditioned response (UR). Salivation is salivation. What makes it "conditioned" isn't what the behavior looks like, it's what triggers it. Salivating to food is unlearned (UR). Salivating to a bell is learned (CR). The CR only exists because of the pairing process, which means it can also fade through extinction if the conditioned stimulus keeps showing up without the unconditioned stimulus. Conditioned responses are also usually a bit weaker than the original unconditioned response.
The CR is one of the five core labels in classical conditioning, alongside the neutral stimulus, unconditioned stimulus, unconditioned response, and conditioned stimulus. It's covered in the Classical Conditioning topic guide, and you can't analyze any conditioning scenario without it. The CR also reaches beyond learning theory. Under learning objective AP Psych Revised 4.2.A, implicit attitudes are evaluations people hold without realizing it, and classical conditioning is one way those gut-level reactions form. A conditioned emotional response (feeling uneasy around something because of past pairings) is the mechanism behind a lot of automatic, unexamined attitudes. So the CR connects the behavioral perspective to social psychology, which is exactly the kind of cross-unit thinking AP Psych rewards.

Unconditioned Response (UR) (Unit 4)
The UR is the CR's twin, and telling them apart is the whole game. Both can be the identical behavior, like salivation. The UR happens naturally in response to the unconditioned stimulus; the CR happens because of learning, in response to the conditioned stimulus.
Conditioned Stimulus (CS) (Unit 4)
The CS and CR come as a pair. The CS is the formerly neutral trigger (the bell), and the CR is the learned reaction it produces (salivating). On the exam, if you correctly identify the CS, the CR is whatever behavior follows it.
Counterconditioning (Unit 4)
Counterconditioning is how therapists undo an unwanted CR. If a child has a conditioned fear response to dogs, pairing dogs with something pleasant can replace the fear CR with a calm one. This is the bridge from classical conditioning to behavioral therapy.
Implicit Attitudes (Unit 4)
Implicit attitudes are evaluations you hold without conscious awareness, and conditioned emotional responses are one way they form. A negative gut reaction you can't explain often works exactly like a CR, an automatic response built from past pairings rather than deliberate thought.
Classical conditioning almost always shows up as a scenario question. You'll get a short story (a kid flinches at the dentist's drill sound, a cat runs to the kitchen when the can opener whirs) and you have to label each piece, including the CR. The trap answer is always the UR, because the behavior looks identical. Anchor yourself to the trigger. If the reaction follows the originally neutral stimulus, it's the CR. No released FRQ has required the term verbatim, but conditioning vocabulary is fair game in the Article Analysis Question and Evidence-Based Question whenever a study involves learned associations, so practice applying the label to fresh scenarios, not just Pavlov's dogs.
This is the most common point lost on conditioning questions because the CR and UR are frequently the exact same behavior. The difference is entirely about the trigger and whether learning was required. Salivating when food hits your tongue is a UR, a reflex you were born with. Salivating when you hear a bell is a CR, because the bell only gained that power through repeated pairing with food. Quick test for any scenario: ask "would this reaction happen without any learning history?" If yes, it's the UR. If the reaction only exists because of past pairings, it's the CR.
A conditioned response is the learned, automatic reaction to a conditioned stimulus, like Pavlov's dogs salivating to a bell alone.
The CR and UR are often the same behavior; what makes a response "conditioned" is that it follows the learned stimulus, not the natural one.
The CR is usually weaker than the UR and can fade through extinction if the conditioned stimulus stops being paired with the unconditioned stimulus.
Conditioned emotional responses help explain how implicit attitudes form, linking classical conditioning to social psychology within Unit 4.
On scenario questions, identify the originally neutral stimulus first; whatever reaction it now triggers is the conditioned response.
A conditioned response (CR) is a learned, automatic reaction to a conditioned stimulus that develops through repeated pairing with an unconditioned stimulus. In Pavlov's classic study, salivating to the sound of a bell alone is the CR.
No, even though they often look identical. The UR is an unlearned reflex to the unconditioned stimulus (salivating to food), while the CR is a learned reaction to the conditioned stimulus (salivating to the bell). The CR also tends to be weaker than the UR.
It's a CR. The bell started as a neutral stimulus, so any response to it had to be learned through pairing with food. Salivating to the food itself is the UR.
Yes. If the conditioned stimulus is repeatedly presented without the unconditioned stimulus, the CR weakens and fades, a process called extinction. The CR can briefly return later through spontaneous recovery, which shows the learning wasn't fully erased.
The conditioned stimulus (CS) is the trigger, and the conditioned response (CR) is the reaction. The bell is the CS; the salivation it produces is the CR. Stimuli are things in the environment, responses are behaviors.
