Chapter 5 Learning- any relatively permanent change in behaviour resulting from experience Classical Conditioning Classic conditioning is when a stimulus such as a buzzer from the microwave triggers a response such as salvation due to pervious learning that popcorn is being made. Pavlov’s Early Work on Classical Conditioning Stimuli- physical events capable of affecting behaviour Pavlov realized that dogs began to salivate when the smelt or saw food or even saw the pan that it was on or the person that brought it to them He geared his experiment toward this observation; Dogs were placed with an apparatus of a dish with food and he introduced a neutral stimulus- a bell. He put the meat into the dogs mouth and he immediately salivated; a natural reaction. He repeated this many times before taking away the meat and only using the bell. He realized that through the sound of the bell the dog would salivate even without presentation of meat products Unconditioned stimulus- in classic conditioning the stimulus that can elicit an unconditioned response- meat powder Unconditioned response- a response elicited by an unconditioned stimulus- salivation Conditioned stimulus- a stimulus paired with an unconditioned stimulus- the bell Conditioned response- the response to the conditioned stimulus- salivation in response to the bell CC-Not limited to one conditones stimulus- if a light is presented with the bell it can work as a conditioned stimulus as well.- second order conditioning Basic Principles of classical conditioning Acquisition- the process by which a conditioned stimulus acquires the ability the elicit a conditioned response through repeated pairing of an unconditioned stimulus with a conditioned one. Temporal arrangement- means time related and refers to the point in time in which the conditioned stimulus occurs. Two temporal arrangements include o Delayed conditioning- form of forward conditioning in which the CS (light) precedes but overlaps the presentation of the UCS (shock) o Trace Conditioning- presentation of the CS precedes but doesn’t overlap the UCS. o Simultaneous conditioning- a form of conditioning which the conditioned stimulus and the unconditioned stimulus begin and end at the same time o Backward conditioned- type of conditioning in which the presentation of the UCS precedes the presentation of the CS.

The process through which a CS gradually looses the ability to elicit conditioned responses when it is no longer followed by the UCS. Ex. Bosses footsteps Spontaneous recovery- following extinction, return of a conditioned response upon reinstate of the UCS-CS pairings. Weaker.
