More on Pavlov's expertment

 

Conditioned Stimulus (CS)Bell / Metronome A previously neutral stimulus that, after association, triggers a response. Conditioned Response (CR)Salivation (to bell)The learned reaction to the previously neutral stimulus.

Two Types of Responses

Through these experiments, Pavlov concluded that organisms interact with their environment using two distinct types of responses:

1.           Unconditioned (Unlearned) Responses: These are reflexes. They occur naturally and automatically without any prior experience or training (e.g., salivating when tasting food).

2.           Conditioned (Learned) Responses: These are behaviors that develop through experience. The organism learns to respond to a new signal because it has been associated with a natural reflex (e.g., salivating at the sound of a bell).

Core Mechanics of Classical Conditioning

Term	Pavlov's Experiment	Definition
Unconditioned Stimulus (UCS)	Food	A trigger that naturally and automatically causes a response.
Unconditioned Response (UCR)	Salivation (to food)	The unlearned, automatic reflects the unconditioned stimulus.
Conditioned Stimulus (CS)	Bell / Metronome	A previously neutral stimulus that, after association, triggers a response.
Conditioned Response (CR)	Salivation (to bell)	The learned reaction to the previously neutral stimulus.
