Document Summary

Pavlov and the conditioned response: dog"s salivation could be set off by a range of other stimuli, unconditioned response- biologically determined reflex, triggered by a certain stimulus independent of any learning. Trigger for an unconditioned response was an unconditioned stimulus. Us = food in the animal"s mouth; ur = salivation. Conditioned response- triggered by a specific stimulus, but it"s stimulus that was neutral at the start of learning. Conditioned stimulus- a stimulus that"s initially neutral but becomes associated with the us during the experiment. Major phenomena of classical conditioning: acquisition of conditioned response. Learning is gradual; strength of the cr slowly grows as the animal experiences more and more pairings of cs and us. Second-order conditioning- a procedure in which a neutral stimulus (the bell) is paired with some already established cs (like the light: ex. Extinction- the undoing of a previously learned response so that the response is no longer produced.
