Transcript

  • 1. Classical Conditioning: The Elements of Associative LearningIvan Pavlov Conditioning Trial: Salivation Test Trial: Salivation
  • 2. Classical Conditioning: DefinitionsUnconditioned Stimulus (US): a stimulus that has the ability toproduce a specified response before conditioning begins. (FOOD)Unconditioned Response (UR): the response produced by theUS. (SALIVATION PRODUCED BY FOOD)Conditioned Stimulus (CS): an initially neutral stimulus thatcomes to produce a new response because it is associatedwith the US. (BELL)Conditioned Response (CR): the response produced by theCS. (SALIVATION PRODUCED BY THE BELL)
  • 3. Classical Conditioning: Basic Principles AcquisitionRepeatedly pairing a CS with a US will produce a CR.1 pairing = presenting the CS and then quickly presenting the US: ExtinctionAfter conditioning has taken place, repeatedly presenting the CSwithout the US will make the CR weaker and eventually make itdisappear. X
  • 4. Classical Conditioning: Additional Principles Spontaneous RecoveryFollowing extinction, the CR reappears at reduced strength if theCS is presented again after a rest period. Stimulus GeneralizationAfter a CR has been trained to a CS, that same CR will tend tooccur to similar stimuli without further training;The greater the similarity, the stronger the response will be. Conditioning: Test for Generalization:
  • 5. Classical Conditioning Stimulus DiscriminationA subject responds to the CS but not to a similar stimulus becausethe CS was paired with a US but the similar stimulus waspresented without the US. X
