"Classical conditioning is the process by which an initially neutral stimulus (the conditioned stimulus or CS) by virtue of presentation with a biologically significant reinforcer (the unconditioned stimulus or US) comes itself to elicit a characteristic response (the conditioned response or CR)" (Hall & Stewart, 2010, p. 95).
