classical conditioning

a term from behaviourism for the process by which two stimuli are presented together until the reflex response to one stimulus occurs when the other is presented alone, thereby creating a conditioned or learned response. The most common example is that of Ivan Pavlov (1849-1936) whose dog learned to salivate at the sound of a bell, it having previously been sounded simultaneously with the presentation of the unconditioned stimulus of food (see conditioning; operant conditioning; reinforcement).
