Goals for the Day: What are you doing today? We will begin the LEARNING UNIT – Today we will begin to talk about Classical Conditioning Let’s get started: 1. Grab your computer and sign-in to your email and click on One Note 2. Go to the COLLABORATION SPACE SECTION – Find your name and that will be where you answer the following question: Important Question: Who is the one person you have learned the most from in your life? Why? Answer in your section in the collaboration space Next Assignment: Switch computers with the person next to you. You will be their scribe (write the info for them) There is a PowerPoint – Are you superstitious? – in the collaboration space page – Ask each other the questions and tally the NO’s. LEARNING Classical Conditioning Stimulus, Response, Neutral Stimulus, Conditioned Stimulus, and Conditioned Response Who developed classical conditioning? Ivan Pavlov – 1904 Nobel Prize Winner in Physiology Here’s What He Used….. Stimulus Conditioned Stimulus (CS) Unconditioned Stimulus (UCS) Neutral Stimulus (NS) Unconditioned Response (UCR) Conditioned Response (CR) Diagram This Situation... Connor loves Chocolate Chip Cookie Dough ice cream from Scoops. He never paid much attention to the ice cream scooper they used to scoop the ice cream with until one day the scooper flew out of the server’s hand and hit him in the head and gave him a terrible headache. Now every time, he walks by scoops, he gets a splitting headache. In the story above, list the following: Neutral Stimulus (NS): _______________ Response (R): ______________________________ Unconditioned Stimulus (UCS): Unconditioned Response (UCR): __________________ _________________ Conditioned Stimulus (CS): ___________________ Conditioned Response (CR): ___________________ Tough to do when you don’t know what the terms mean. So let’s learn what they mean…. What’s a STIMULUS? A STIMULUS is something that causes a response Unconditioned Stimulus A stimulus that you did not have to be TAUGHT to react to You react by instinct Unconditioned Response A response that you DID NOT have to be trained to react to Conditioned Stimulus A stimulus that you have to be TAUGHT to reach to Conditioned Response A response that you have to be TAUGHT to reach to Neutral Stimulus A stimulus that doesn’t mean anything to you yet Classical Conditioning Pavlov studied how a person could control a dog’s behavior He especially focused on dog drool Classical Conditioning Pavlov wanted the dogs to drool every time he rang a bell What’s happening here? Unconditioned Stimulus (UCS) Unconditioned Response (UCR) Now the Learning Process… What’s happening here? Pavlov then RANG THE BELL as he showed the dog food…. And THE DOG DROOLED! Neutral Stimulus (NS) Unconditioned Stimulus (UCS) Unconditioned Response (UCR) So ultimately….. Neutral Stimulus (NS) becomes a Conditioned Stimulus (CS) Unconditioned Stimulus (UCS) Unconditioned Response (UCR) becomes a Conditioned Response (CR) So ultimately….. After awhile, Pavlov only had to ring the bell and the dog would drool! Conditioned Stimulus (CS) Conditioned Response (CR) Diagram This Situation... Connor loves Chocolate Chip Cookie Dough ice cream from Scoops. He never paid much attention to the ice cream scooper they used to scoop the ice cream with until one day the scooper flew out of the server’s hand and hit him in the head and gave him a terrible headache. Now every time, he walks by scoops, he gets a splitting headache. In the story above, list the following: Neutral Stimulus (NS): _______________ Response (R): ______________________________ Unconditioned Stimulus (UCS): Unconditioned Response (UCR): __________________ _________________ Conditioned Stimulus (CS): ___________________ Conditioned Response (CR): ___________________ So ultimately….. You will see the terms of Classical Conditioning everywhere now that you know about them. Extensions of Classical Conditioning What are extensions? After “discovering” classical conditioning, Pavlov spent of his life expanding upon his ideas. He cam up with some “extensions” that further develop/add on his theory. What are the extensions? Acquisition Extinction Spontaneous Recovery Generalization Discrimination Higher-Order Conditioning Acquisition The Preliminary stage of LEARNING – This is when the person first CONNECTS the events together in their minds (It goes from unconditioned to conditioned) Extinction The WITHDRAWING of a conditioned response. Occurs when you stop pairing the US and NS/CS and time passes Spontaneous Recovery The RECURRENCE of a conditioned response after a rest period following extinction. You have to connect the CS and NS again for it to re-appear Generalization When stimuli similar to the neutral stimulus BRING FORTH SIMILAR RESPONSES as the neutral stimulus. “Yay! I love when Mr. C feeds me canned food! NOM NOM NOM NOM NOM NOM NOM NOM” “Wait a second… IS THAT A CAN I HEAR???” “Yay! I’m about to get food! …Where is it???” Discrimination When an organism DOESN’T RESPOND TO SIMILAR STIMULI as the neutral stimulus. Opposite of generalization. Don’t confuse this with social psych’s discrimination. “Yay! I love when Mr. C feeds me canned food! NOM NOM NOM NOM NOM NOM NOM NOM” “I just heard Mr. C open a can of soda. Not gonna fall for that one, bro.” “Since I’m not being fed I think I’ll go spin instead.” Higher-Order Conditioning After classical conditioning has successfully been established, THE PAIRING OF A SECOND NEUTRAL STIMULUS with the previously conditioned stimulus. Cognitive Processes of CC Does classical conditioning work as well on humans as it does on animals? NO, because of our COGNITION and INTELLIGENCE Classical Conditioning and Phobias What are your PHOBIAS? Superstitious Believing something will happen, good or bad, because change or magic instead of logic or common sense What are your PHOBIAS? Phobia Being so fearful or something, no matter how rational or irrational, that makes a person do just about anything to avoid it Top Ten Phobias Phobia Top Ten Phobias 10. Necrophobia – Fear of Death Top Ten Phobias 9. Brontophobia – Fear of lighting/thunder Top Ten Phobias 8. Mysophobia – Fear of Germs/Dirt Top Ten Phobias 7. Emetophobia – Fear of Vomit Top Ten Phobias 6. Claustrophobia – Fear of Confinement Top Ten Phobias 5. Agoraphobia – Fear of Open spaces/crowds Top Ten Phobias 4. Aerophobia – Fear of Flying Top Ten Phobias 3. Acrophobia – Fear of Heights Top Ten Phobias 2. Glossophobia – Fear of Public Speaking Top Ten Phobias 1. Arachnophobia – Fear of Spiders Phobic Anxiety Disorder Typical Symptoms include: Dizziness, rapid heartbeat, trembling, or other uncontrollable physical response Sensation of terror, dread or panic Preoccupation of thoughts; inability to change focus from the feared situation Intense desire to flee the situation Reducing Fears and Phobias Flooding A person is exposed to the harmless stimulus until fear responses to that stimulus are extinguished Reducing Fears and Phobias Counterconditioning A pleasant stimulus is paired repeatedly with a fearful one, counteracting the fear Reducing Fears and Phobias Bell and Pad Methods US = Bell UR = Wake-up and preventing urination CS = Blatter Tension CR = Wake-up and preventing urination All of these are Classical Conditioning John B. Watson and Little Albert US = Loud bar sound UR = Fear/Crying CS = White Rat CR = Fear/Crying Operant Conditioning Edward Thorndike I was the first person to ask for rewards!!! Thorndike came up with the LAW OF EFFECT (Rewarded behavior is likely to recur) around 1900. B.F. Skinner B.F. Skinner extended and formalized Thorndike’s ideas beginning around 1940. B.F. Skinner is best known for OPERANT CONDITIONING B.F. Skinner Operant Conditioning – Learning behavior as a result of effects and consequences. For example, if our actions result in people getting angry or disliking us, we are being operant conditioned to believe the world is a dangerous place. B.F. Skinner Reinforcement – Something that strengthens the response or makes it more likely to recur. Operant Chamber or Skinner Box Operant Chamber or Skinner Box – contains a bar that an animal can push to obtain a food reinforcer with a recorder of the bar pressing. Shaping Procedure where reinforces (food), gradually guides an animal’s actions toward a desired behavior The Consequence of Behavior Reinforcement When your dog begs for food at the table, and you give him/her a scrap. The result in the begging will increase. Positive and Negative Reinforcement Positive Reinforcement A stimulus that increases the frequency of a behavior when it is presented. Examples: Hungry rewards with food. Athletes reward with playing time. Your 16 reward with Driving. Positive and Negative Reinforcement Negative Reinforcement An unpleasant stimulus that increases the frequency of behavior when it is removed or avoided Examples: Hot sun, we move to shade. Tired, we go to sleep. Take out trash to avoid mom yelling. Positive and Negative Reinforcement Behavior: Studying Negative Reinforcement: Poor Grades Positive Reinforcement Good Grades Result: Studying Increases Punishments Weakening a response by following it with unpleasant consequences. F Punishments Weakening a response by following it with unpleasant consequences. F Punishments Problems with Punishments 1. Doesn’t erase behavior, just suppresses it 2. Only works when guaranteed and immediate 3. May have bad side effects – resent parent, and no admittance, or opposite effect. 4. May be abusive or imitated as the only way to solve problems 5. Does not teach acceptable behavior Punishments Do you agree with spanking in school? Punishments Types of Punishments Positive Punishment Administer a “bad stimulus” to decrease a behavior. Example: Spanking, speeding ticket Same child – 13 days later Punishments Types of Punishments Negative Punishment Withdraw a rewarding stimulus to decrease a behavior Example: take cell phone, or license Which punishment hurts more? Primary and Secondary Reinforcement Primary Reinforcement Reinforcement that uses a physical survival need. (food, water, and adequate warmth) Primary and Secondary Reinforcement Secondary Reinforcement Reinforcement that comes to represent a primary reinforcer. (Money, attention, social approval) Reinforcement Schedules Partial or Intermittent Reinforcement Reinforcing a response only part of the time – 4 types 1. Fixed-Ratio Schedules (FR) – reinforce behavior after a set number of responses – Example: Coffee card 2. Variable-Ratio Schedules (VR) – reinforce after unpredictable number of responses – Example: Gambling. Reinforcement Schedules Partial or Intermittent Reinforcement 3. Fixed-Interval Schedule (FI) – reinforce the 1st response after a fixed time period – Example: Checking Mail 4. Variable-Interval Schedules (VI) – reinforce the 1st response after a varying time period. There is no knowing when the waiting is over – Example: Email. Why do we act stupid??? 1. Operant Conditioning is stronger when delivery of the reinforcer is immediate 2. The larger the reinforcer, the more effective Cognitive Factors in Learning Cognitive Factors in Learning Cognitive Learning Learning is NOT so mechanic, but we learn because we want to. We seek out knowledge by thinking or watching people. Cognitive Factors in Learning Two Type of Cognitive Learning Latent Learning Observational Learning Cognitive Factors in Learning Latent Learning Learning that occurs but remains hidden until there is a need to use it. Rats learned by roaming the maze E.C. Tolman Cognitive Factors in Learning Cognitive Maps Mental map of a physical area. Rats created mental map of the maze E.C. Tolman Cognitive Factors in Learning Insight and Learning Insight – A sudden understanding and solving of a problem • Chimps acted as if they understood the problem • Chimps rarely tried a solution that didn’t work out. The animals often reached a solution suddenly Wolfgang Kohler Cognitive Factors in Learning Observational Learning Learning by watching and imitating others. Mirror Neurons Fire when performing a certain action, or observing a certain action Do-er Watcher Cognitive Factors in Learning Alfred Bandura Showed that we acquire knowledge by MODELING MODELING – the process of observing and imitating a specific behavior.
