Term: Conditioned Stimulus
Definition (Myers): in classical conditioning, an originally irrelevant stimulus that, after association with an unconditioned stimulus, comes to trigger a conditioned response (1)
Definition (alternative): A conditioned stimulus in Pavlovian conditioning is an initially neutral stimulus that is paired with the unconditioned stimulus. For example, a tone sounded just prior to the puff of air being delivered to the cornea of the eye. Without prior training, the tone does not elicit an eye blink: however, after a number of tone-puff pairings, the tone alone comes to elicit the blinking response. Conditioned Stimulus (2)
Contextual explanation: A conditioned stimulus is a stimulus that gains the capacity to cause a particular response to take place after repeated pairing with another neutral stimulus. For example, a dog that is continuously exposed to bell sound before getting its meals, the dog will associate bell sound with its meals. Therefore, the bell sound becomes conditioned stimulus while the dog's salivation becomes its conditioned response.
