10/7/08 Chapter 6: Learning Learning: o Relatively permanent change in organism’s behavior due to experience. Associative learning: o Learning that certain events go together. i.e. video clip- when he heard the noise he got a mint. Conditioning: o Process of learning associations Three main types of learning o Classical conditioning o Operant Conditioning o Observational learning Classical Conditioning Ivan Pavlov in 1903 o Tried to get dogs to salivate at the sound of a tone. Definition: type of learning in which a stimulus acquires the capacity to produce a response that was originally produced by another stimulus. o i.e. tone paired with meat powder Unconditioned stimulus (UCS): o A stimulus that naturally/automatically triggers a response o Pavlov: meat powder Unconditioned response (UCR): o The unlearned, naturally occurring response to the UCS. o Pavlov: salivating after meat powder Conditioned stimulus (CS): o Previously neutral stimulus that after association with an UCS comes to trigger a response. o Pavlov: tone Conditioned response (CS): o Learned response to a previously neutral CS.

o Pavlov: salivating after tone o CS and CR are often the same behavior, just evoked by different things. For conditioned substitute the word learned. Process of Classical Conditioning Originally UCS and UCR are paired together naturally o Meat powder=salivating During conditioning UCS and CS are presented together in time leading to the UCR o Tone then meat powder=salivating Eventually, the CS can produce a CR all by itself o Tone=salivating Basic Conditioning Processes Acquisition: the initial stage of learning, during which a response is established and gradually strengthened. o This is the phase when the CS comes to evoke the CR Pavlov: dogs began salivating to the tone Extinction: the diminishing of a conditioned response o Stop pairing UCS with CS and eventually CS stops causing CR o Pavlov: dogs stop salivating to tone Spontaneous Recovery: the reappearance of an extinguished conditioned response o Stop pairing UCS with CS and eventually extinction occurs o Give a break from procedure
