AP PSYCHOLOGY

Detailed explanation-1: -Classical conditioning requires the existence of an unconditioned stimulus (UCS) that elicits an unconditioned response (UCR), that is, that reliably elicits an unlearned response, in the experimental subject. UCRs (unlearned responses) are also known as reflexes.

Detailed explanation-2: -The difference between an unconditioned stimulus and a neutral stimulus is that an unconditional stimulus (UCS) elicits a natural, reflexive response, called the unconditioned response (UCR), while a neutral stimulus (NS) doesn’t naturally elicit the same response.

Detailed explanation-3: -In the learning process known as classical conditioning, the unconditioned stimulus (UCS) is one that unconditionally, naturally, and automatically triggers a response. In other words, the response takes place without any prior learning.

Detailed explanation-4: -the unlearned response to a stimulus. In other words, it is any original response that occurs naturally and in the absence of conditioning (e.g., salivation in response to the presentation of food).

Detailed explanation-5: -The unconditioned stimulus (UCS) is a stimulus that causes a response automatically. In Pavlov’s experiment, the UCS was the meat powder. The unconditioned response (UCR) is the automatic response to the unconditioned stimulus. In Pavlov’s experiment the UCR was the dog salivating.
