• Learning caused by pairing and association of two stimuli
• Learning by responding to environmental stimuli
• Learning explained by its consequences
• Learning explained by modelling 

Define conditioned response

• A response that has been learned
• A stimulus that produced the response in an unconditioned reflex

Who is the psychologist known for Classical Conditioning

• Ivan Pavlov

In classical conditioning, the UCR:

• happens after the CR
• is the response to the CS.
• is the response to the UCS
• triggers the UCS to occur.

The conditioned stimulus (CS):

• is the response to the US.
• is originally the neutral stimulus that gains the power to cause the CR.
• triggers an unconditioned response reflexively or automatically when the CR happens.
• is what triggers the US to occur.

The conditioned response (CR) is the usually the same as the

• CS
• UCS
• UCR
• CR
