Learning What does it mean to learn? Are there different ways to learn? Why are Pavlov’s dogs so famous? What is classical conditioning? Who is Baby Albert? 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 NS – UCS – Meat Powder UCR – CS - Metronome CR - Little Albert: John B. Watson NS- bunny or rat UCS- UCR CS 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)
