Unformatted text preview: e (UR): a response to a stimulus that is automatic Classical Conditioning Classical • After detecting the initial pairing of information, a “neutral stimulus” (NS) is presented to the individual • A “training” or “pairing” procedure then begins until the neutral stimulus is recognized to be associated with the unconditioned stimulus • This pairing of stimuli eventually leads to a “conditioned response” (CR) to the newly “conditioned stimulus” (CS) The Classical Conditioning Formula The Important Concepts Related to CC Important • A learning curve indicates how likely the NS/CS is to elicit the CR over time, and varies between pairings • If, after the conditioning, the CS is presented without the US repeatedly, the association will deteriorate and the CS will return to being a NS, this called extinction • An extinction curve can also be figured out to show how quickly a learned pairing is lost • Note: extinguished associations can be reconditioned (usually faster than the initial conditioning) AND, sometimes organisms show spontaneous recovery of extinguished behaviors Extinction and Spontaneous Recovery Strength of CR Acquisition “Learning” (CS+US) Extinction “Forgetting” (CS alone) Spontaneous recovery of CR Extinction (CS alone) Pause What influences the strength of a learned response? learned Conditioning occurs more rapidly when the Conditioning neutral stimulus is relatively unfamiliar neutral The less time that elapses between the The presentation of the CS and the UCS, the faster the CR is acquired faster The CR will be acquired more quickly when The the CS precedes the UCS (forward conditioning) conditioning) Specific connections between CSs and UCSs Specific are inherently strong in us and other species are Rat and Poison example What happens when stimuli are similar to the neutral stimulus? • Sometimes, organisms respond with a CR to a new stimuli that closely resemble the CS, this is called generalization • Organisms can also not respond to a new and similar stimulus as if it were the same as the CS, this is called discrimination What does this tell us about learning? What It tells us how we can learn about how our It minds might pair stimuli with each other minds However, it doesn’t inform us about how we However, know about what to do and not to do in our world world In our next class we’ll revisit the world of In behaviorism from a different perspective; from the world of operant conditioning the Have a good week!
