The Altoid Theory: http://www.youtube.com/watch?v=WfZfMIHwSkU&feature=related Learning What does it mean to learn? Provide a definition in your notebook. • A relatively permanent change in behavior or the potential to make a response that occurs as a result of experience. • Give an example from today of something you have learned…. What are the three types of learning? • Classical Conditioning: Respondent • Operant Conditioning: Instrumental • Observational Learning: Modeling What is your response to the following stimuli? • You have not eaten for days and you are presented with your favorite food • You are in a hurry and stuck in traffic with your mom. • You are watching tv and Dr. Phil comes on. • You hear a Brittany Spears song on the radio. • You are full but you see an entire bag of BBQ chips. Why are Pavlov’s dogs so famous? Classical Conditioning • Ivan Pavlov 1849-1936 • Nobel Prize in 1904 for studies of digestion! • • But really, what he did was test Classical Conditioning! CC: Learning that occurs when two stimuli are paired and become associated with each other. http://www.learner.org/discoveringpsychology/08/e08expand.html?pop=yes&pid=1529# Watch for 16:30 seconds Basic Elements of Classical Conditioning • Stimulus: trigger or event • Neutral Stimulus (NS) - Stimulus that does not elicit a particular response. (Who cares) • Unconditioned Stimulus (UCS) - Event that automatically produces a response without any previous training. (Causes an immediate reaction) • Unconditioned Response (UCR) - Reaction that is automatically produced when an unconditioned stimulus is presented. (Reflex) Classical Conditioning Continued • Conditioned Stimulus (CS) - Neutral Stimulus that acquires the ability to elicit a conditioned response after being paired with an UCS. (Mistaken identity!) • Conditioned Response (CR) - Response elicited by a conditioned stimulus that has been paired with an unconditioned stimulus; is similar to the unconditioned response. (False response) Pavlov’s Dog vs. Little Albert • Pavlov’s Dog: Ivan Pavlov • Little Albert: John B. Watson • NS – • NS- bunny or rat • UCS – Meat Powder • UCS- • UCR – • UCR • CS - Metronome • CS • CR - • CR Are these studies ethical? Other vocab terms • Acquisition: training stage of when is a response is learned • Extinction: elimination of response • Spontaneous Recovery: response comes back after elimination • Generalization: response spreads to other things • Discrimination: response is only directed at CS • Taste Aversion: when food is a CS for a bad CR • (BBQ Chips) What did you learn? • Let’s do an experiment! • 3 volunteers, trust us! • Quiz! • http://www.soundjay.com/beep-sounds-1.html • Homework: • Read pages 199-212
