The more similar a stimulus is to the condition stimulus, the more likely the organism is to give the conditioned response. Pavlov's groundbreaking work on the learning process, known as classical conditioning, involved the repeated pairing of two stimuli, first presenting a(n) _____ stimulus and then a(n) _____ stimulus. In Rescorla's experiment, he played specific tones of sound for lab rats. [4] Rescorla was a Professor Emeritus of psychology at the University of Pennsylvania . conditioned stimulus; unconditioned response, conditioned stimulus; conditioned response, Pavlov taught a dog to salivate at the sound of a ticking metronome by repeatedly pairing food with a metronome.

In classical conditioning, the initial period of learning is known as acquisition, when an organism learns to connect a neutral stimulus and an unconditioned stimulus. I would definitely recommend Study.com to my colleagues. Researched classical conditioning finding that subjects learn the predictability of an event through trials (cognitive element).
Biography of Psychologist Albert Bandura - Verywell Mind Minimize. In this case, the chemotherapy drugs are the unconditioned stimulus (UCS), vomiting is the unconditioned response (UCR), the doctors office is the conditioned stimulus (CS) after being paired with the UCS, and nausea is the conditioned response (CR).
