Classical conditioning

• Pavlov's dogs were used as subjects in classical conditioning experiments, where they learned to associate food with a bell ringing sound.
• The unconditioned response (UCR) is a natural reaction that occurs without prior learning.
• The conditioned stimulus (CS) is originally neutral but becomes associated with the US through repeated pairings.
• The neutral stimulus (NS) is initially meaningless but becomes associated with the UCS through repeated pairings.
• The unconditioned response (UCR) is the natural or automatic reaction that occurs when the unconditioned stimulus (US) is presented alone.
• Classical conditioning involves associating two previously unrelated events or stimuli together until one event triggers an automatic response.
• The conditioned response (CR) is a new behavior or physiological change that develops through association with the CS.
