CONDITIONING AND LEARNING 1. CLASSICAL CONDITIONING WHAT IS LEARNING? A relatively permanent change in behavior due to experience EARLIEST EXPERIMENTS: IVAN PAVLOV Guess what? We already did this. What do you remember? LATER EXPERIMENTS: JOHN WATSON Guess what? We already did this. What do you remember? JOHN WATSON CONT. Founder of behaviorism What is the main tenet of behaviorism? Behaviorism is not EXCLUSIVELY used today very frequently Cognition is also part of learning…duh Watson thought it was impossible to study cognition, and so decided that it was useless to speculate…but now what can we do? THE PARTS OF CLASSICAL CONDITIONING Stimulus: Anything in the environment that an organism can respond to. What does that mean in real terms? Response: Any behavior or action. Surprisingly hard to define… THE PARTS OF CLASSICAL CONDITIONING CONT. Unconditioned Stimulus (UCS): A stimulus that triggers a response automatically and reflexively. What are some examples? THE PARTS OF CLASSICAL CONDITIONING CONT. Unconditioned Response (UCR): The automatic response to the unconditioned stimulus. THE PARTS OF CLASSICAL CONDITIONING CONT. Conditioned Stimulus (CS): A previously neutral stimulus that, through learning, has gained the power to cause a conditioned response. THE PARTS OF CLASSICAL CONDITIONING CONT. Conditioned Response (CS): The response to the conditioned stimulus, or, the UCR that has been transferred from the UCS to the CS. Mouthful. MORE TERMINOLOGY Acquisition: The process of developing a learned response Extinction: The diminishing of a learned response; when a UCS does not follow a CS How long do you think the dogs salivated when the metronome chimed? The boy who cried wolf SPONTANEOUS RECOVERY The reappearance, after a rest period, of an extinguished conditioned response. GENERALIZATION Generalization: A process in which an organism produces the same response to two similar stimuli. DISCRIMINATION Discrimination: A process in which an organism produces different responses to two similar stimuli. GROUP ASSIGNMENT At your table, come up with three classical conditioning scenarios Does your sister bug you? A parent ride you? A fellow student bully you? Etc. For each scenario, operationalize how you will condition their behaviors by outlining the following terms for each case: UCS UCR CR CS If you go to far and they have generalized too much, how will you get them to learn to discriminate? When the experiment is over, you don’t want to pull a Little Albert. How will you bring the conditioning to extinction?
