noun - Pavlovian Response is a physiological and psychological response due to Pavlovian conditioning or respondent conditioning which is a form of learning in which one stimulus, the conditioned stimulus, comes to signal the occurrence of a second stimulus, the unconditioned stimulus. The unconditioned stimulus is usually a biologically significant stimulus such as food or pain that elicits a response from the start; this is called the unconditioned response. The conditioned stimulus usually produces no particular response at first, but after conditioning it elicits the conditioned response.

Conditioning is usually done by pairing the two stimuli, as in Pavlov’s classic experiments. Pavlov presented dogs with a ringing bell followed by food. The food (unconditioned stimulus) elicited salivation (unconditioned response), and after repeated bell-food pairings the bell also caused the dogs to salivate (conditioned response).

[edit] With Cold Water Swimmers

Anticipatory thermogenesis is a term coined by Professor Tim Noakes of the University of Cape Town when he recorded Lewis Pugh's ability to raise his core body temperature by nearly 2°C in anticipation of entering the freezing water during his swims in Antarctica. Anticipatory thermogenesis or the creation of heat before an event is a phenomenon that had not been noted in any other human. Pugh believes it is a Pavlovian Response to years of cold water swimming.
