Document Summary
Classical conditioning- the learning of a contingency between a particular signal and a later event that are paired in time and/or space. Instrumental conditioning- allows us to associate actions and consequences.

Contingencies- when one stimulus reliably predicts the presentation of another. When a contingent event is learned, an organism can respond to the signal before the event even occurs. Imagine lemons in your mouth, you start salivating to neutralize citric acid and to prepare body for digestion. By doing this your body is trying to maintain homeostasis. Unconditional response (ur) the response that occurs after the unconditioned stimulus. Conditional stimulus (cs) paired with the unconditioned stimulus to produce a learned contingency. (ex. Sight and sound of lemon is cs after being repeated with the us)
