Initial Responses to the Stimuli Novelty of Conditioned and Unconditioned Stimuli CS and US Intensity and Salience CS- US Relevance, or Belongingness Learning Without an Unconditioned Stimulus What Determines the Nature of the Conditioned Response? The Stimulus- Substitution Model Learning and Homeostasis: A Special Case of Stimulus Substitution The CS as a Determinant of the Form of the The CS as a Determinant of the Form of the CR Conditioned Responding and Behavior Systems S-R versus S-S Learning Excitatory Pavlovian Conditioning Procedures Control Procedures for Classical Conditioning pseudo- conditioning. Increases in responding observed with repeated CS- US pairings can sometimes result from exposure to just the US. Exposure to just the US produces increased responding to a pre-viously ineffective stimulus. explicitly unpaired control A procedure in which both conditioned and uncondi-tioned stimuli are presented, but with sufficient time between them so that they do not become associated with each other. Outline Basic conditioning phenomena acquisition, extinction, spontaneous recovery, etc Temporal relationship between CS and US Control Procedures for classical conditioning Pseudoconditioning, random control, explicitly unpaired control Measurements of conditioned response Inhibitory pavlovian conditioning When participants learn to predict the absence of the unconditioned response Recap Basic principles of of classical conditioning Classical Conditioning Terms Unconditioned Stimulus (US) : A stimulus that will provoke a response without training e.g. food Unconditioned Response (UR) : The response to an unconditioned stimulus e.g. salivation Conditioned Stimulus (CS) : A stimulus that is paired with a US, and comes to provoke the same response as the US (in the absence of the US) e.g. tone Conditioned Response (CR) : The same response as the UR, but now to a CS, rather than to a US e.g. salivation Paradigm of Classical Conditioning 1 st : Select a stimulus that reliably elicits a characteristic response Stimulus -> Unconditioned stimulus (US) Response -> Unconditioned response (UR) Unconditioned -> Signifies the US - UR connection is unlearned (innate) Paradigm of Classical Conditioning 2 nd : Select a Stimulus for Conditioning (CS) Can be any reasonable stimulus that does not initially evoke the UR Neutral stimulus Conditioned Signifies that CS will only elicit desired response (CR) after conditioning take place Standard paradigm of classical conditioning Experimental Situations (p.63-74)Experimental Situations (p....
