Daily Sheet pg. 86 Operant Conditioningpeople can learn voluntary behaviors through the consequences of those behaviors (with rewards and punishments) Reinforcer- a reward that INCREASES the frequency of the behavior it follows Punishment- something that DECREASES the frequency of the behavior it follows
Classical Conditioning Review 1. Who is the first psychologist to study classical conditioning? (Hint: dog drool) 2. Who took this study and applied it to humans in the Little Albert experiment? 3. In the classic conditioning study where dogs were taught to salivate at a neutral stimulus, WHAT was the CS? <the neutral stimulus they began drooling to> 4. What do we call the natural, original response to a stimuli? (UCS, UCR, CS or CR) 5. What did Little Albert get conditioned to fear? (the CS) 6. As a result of generalization, what happened to Little Albert s fear? 7. In the following scenario, identify the UCS, UCR, CS and CR. Holly and her ex best friend used to always eat nacho cheese Doritos on the way to high school each morning. Now, whenever she smells Doritos, Holly feels young and carefree just like she did back then.
Operant Conditioning- People and animals can learn to do certain things (and not do others) by learning from the results of their behavior- VOLUNTARY responses B.F. Skinner (1904-1990) elaborated Thorndike s Law of Effect <people keep doing things that feel good> Used a skinner box in his experiments with animals Skinner Box Example
Reinforcer Increases the Probability of the Behavior It Follows The fundamental principle of behaviorism is that rewarded behavior is likely to be repeated. Example 1 This is known as a positive reinforcement in operant conditioning. Example 2 ex: Your teacher praises you when you get an A A negative reinforcement is when you want a bad feeling/thing to stop so you exhibit a behavior Ex: You put on your seat belt to make the ringing sound stop. OR You take an aspirin to make a headache stop. This is NOT THE SAME as a punishment. You still want the behavior to increase. You are just rewarding the behavior by taking a bad thing away.
Punishment When you get a consequence for a negative behavior so you stop doing the negative behavior Ex: You get grounded for coming home after curfew.
Think-Pair-Share You are a parent of two children, a girl age 7 and a boy age 5. You are concerned because your daughter keeps attacking her younger brother every time she gets upset. You would like to use Skinner s Theory of Operant Conditioning to get rid of this behavior. 1. How would you use the ideas of positive and negative reinforcement to INCREASE the desired behavior? (handling her anger without attacking her brother) 2. How would you use the ideas of positive and negative punishment to DECREASE the undesired behavior? (attacking her brother)
Operant Conditioning Lab I need two volunteers!
Lab Reflection 1. What was the target behavior? 2. Explain how we used a positive reinforcer in the first experiment. What was the reinforcer? Was it successful? How long did it take? 3. Explain how we used a punishment in the second experiment. What was the punishment? Was it successful? How long did it take? 4. In your experience, do you find reinforcers or punishments to be more effective in shaping your behavior?
Positive Behaviors they want to increase Negative Behaviors they want to decrease Examples of Reinforcements Used Examples of Punishments Used
