Unformatted text preview: Learning What Is Learning ? Learning- a relatively permanent change in behavior or knowledge acquired through experience Non-associative learning only one stimulus is present (i.e., one stimulus doesnt predict the second) Orientating Response inborn tendency to notice and respond to novel or surprising events. What Is Learning? Cont Habituation- decreased responsiveness to unchanging stimuli Dishabituation increased responsiveness when habituated stimulus changes Classical Conditioning: Learning Signals and Associations (Associative Learning) Ivan Pavlov Russian physiologist won Nobel Prize in 1904 Components of Classical Conditioning A reflex is a swift, unlearned automatic response to a stimulus A neutral stimulus does not initially trigger the reflex Classical Conditioning repeatedly pairing a neutral stimulus with a stimulus that elicits a reflex until the neutral stimulus alone elicits a similar response Components of Classical Conditioning Cont Phase 1: Prior to Conditioning a. Unconditioned stimulus (UCS meat powder) elicits an Unconditioned Response (UCR - salivation ) a. Neutral Stimulus (bell) elicits Orienting Response (attracts attention). Components of Classical Conditioning Cont Phase 2: The Process of Conditioning ~ Present Neutral Stimulus ( bell ) followed by UCS (meat powder) which elicits the UCR- salivation Components of Classical Conditioning Cont Phase 3: After Conditioning has Occurred ~ Present Conditioned Stimulus (CS- bell ) which now elicits Conditioned Response (CR - salivation ) Pavlovs Dog, Pavlov Museum, 2005 Classical Conditioning Procedure Pavlovs dog http://www.youtube.com/watch?v=CpoLxEN54ho Easy Button http://www.youtube.com/watch?v=Eo7jcI8fAuI Classical Conditioning of Emotions J.
