Unformatted text preview: ch 6 – Learning • learning o collecting skills and knowledge and using them to repeat something after having experienced it Classical Conditioning Pavlov’s demonstration: psychic reflexes What happens in classical conditioning? • classical conditioning o type of learning where you get a response from something that originally could not produce a response • take an unconditioned stimulus and make it conditioned Terminology and Procedures What are the key elements in this type of learning? • unconditioned stimulus o something that causes a response • unconditioned response o a reaction that is not taught and happens automatically • conditioned stimulus o originally a neutral stimulus o produces a response after treatment • conditioned response o a learned reaction Classical Conditioning in Everyday life Other Conditioned Emotional Responses What types of emotional responses are modulated by classical conditioning? • fear • pleasant feelings Conditioning and Physiological Responses What are some physiological processes governed by classical conditioning? • immune response o classical conditioning procedures can lead to immunosuppression • allergic reactions o classical conditioning contributes to growth of drug tolerance and the experience of withdrawal symptoms when drug use stops Basic Processes in Classical Conditioning Acquisition: forming new responses How are conditioned responses acquired? • acquisition o initial stage of learning something • learning a conditioned response depends on stimulus contiguity o stimuli are contiguous if they happen at the same time in the same place • new or unusual stimuli have a greater chance of becoming a conditioned stimulus b/c they are more likely to stand out among other stimuli Extinction: Weakening Conditioned Responses How are conditioned responses weakened? • extinction o gradual weakening and disappearance of a conditioned response o done by presenting the conditioned stimulus alone many times without the unconditioned stimulus Spontaneous Recovery: Resurrecting Responses What is spontaneous recovery? • reappearance of an extinguished response after a period of not being exposed to the conditioned stimulus • the rejuvenated response is weaker than the conditioned response Stimulus Generalization What is stimulus generalization? • when an organism learns to respond to a new stimulus in the same way it responded to the original conditioned stimulus b/c the 2 stimuli are similar • the more similar a new stimuli are to the original conditioned stimuli, the greater the generalization Stimulus Discrimination What is Stimulus Discrimination? • when an organism doesn’t respond to a new stimulus in the same way it responded to the conditioned stimulus, even if the 2 stimuli are similar • usually requires the original conditioned stimulus continue to be paired with the unconditioned stimulus • ex/ dog get excite when it hears your car pull in the driveway o initially it will respond to all cars pulling in (stimulus generalization)...
