Document Summary
Learning that one stimulus reliably and accurately predicts the occurrence of a second stimulus. Unconditional stimulus (us): unconditionally or automatically triggers a response in the absence of any learning, occurs naturally, prior to learning, any stimulus or event, ex. Placing lemon in mouth will make it water without any training. Unconditional response (ur): the response that occurs after the unconditioned stimulus, occurs naturally, prior to learning, ex: lemon elicits saliva. Conditional stimulus (cs): paired with the unconditioned stimulus to produce a learned contingency, ex. Sound of bell paired along with every time the dog is given food will cause the dog to associate. Follows after us that sound with getting food: ex. Conditioned response (cr): response that occurs once the contingency btw the cs and us has been learned, ex. Sound of bell will eventually result in conditional response to salivation.
