Presentation Transcript

  1. 9.1 Classical Conditioning • Classical Conditioning: a learning procedure in which associations are made between a neutral stimulus and an unconditioned stimulus.

  2. Learning: a relatively permanent change in behavioral tendency that results from experience. • Neutral Stimulus: a stimulus that does not initially elicit any part of an unconditioned response. • Unconditioned Stimulus (US): an event elicits a certain predictable response typically without previous training. • Unconditoned Response (UR): An organism’s automatic (or natural) reaction to a stimulus. • Conditioned Stimulus (CS): a once neutral event that elicits a given response after a period of training in which it has been paired with (occurred just before) an unconditioned stimulus. • Conditioned Response (CR): the learned reaction to a conditioned stimulus.

  3. Pavlov’s experiment • Neutral Stimulus: tuning fork (or bell) • Unconditioned Stimulus: food • Unconditioned Response: Salivation • Conditioned Stimulus: tuning fork (or bell) • Conditioned Response: Salivation

  4. Acquisition: of a classically conditioned response generally occurs gradually. • Generalization: responding similarly to a range of similar stimuli. • Discrimination: the ability to respond differently to similar but distinct stimuli. • Extinction: the gradual disappearance of a conditioned response when the conditioned stimulus is repeatedly presented without the unconditioned stimulus.
