1Habituation-Innate responses
-Reflexes
>can both be modified by learning
2Short & Long term habituation-Short term: temporary, immediate decline in response
-Long term: More permanent & slower decline in response
3What do we learn?-CS-US associations, not CS-UR associations
>eg. in tone-shock conditioning, the CR is fear not pain
-Pavlov: CR=UR=salivation
-CR not always same as UR
-CS produces anticipation of US
4Higher order conditioningSomething associated with a CS can also become a CS
5Learning curves-Strength of CR plateaus with increase of conditioning trials
-Asymptote: the US is no longer surprising
-No surprise= no learning
6Timing of conditioning-Delayed conditioning procedure
>NS & US overlap slightly
-Trace conditioning procedure
>NS exposure before US
-Simultaneous conditioning procedure
>NS & US exposure at same time
-Backward conditioning procedure
>overlap, with US before NS
7Overshadowing-Stimuli compete for "associative strength"
-Most salient stimulus acquires most strength
8Blocking-Stimulus competition
-Prior conditioning of one stimulus will lead to blocking of another
-Presence of pretrained CS means US is not surprising so no learning
