Warm Up

Warm Up

Write three hypotheses that you could research using an observational study in a fast food restaurant.

I’m sorry

Prework for study

write the following for each hypothesis: 1. What would you have to measure in this

experiment? (ie: overweight/normal, male/female, number of bites, number of items ordered, amount of food left, number of chews, amount of time spent eating)

2. How would you measure this? (count and record, tally, stopwatch?)

Star the hypothesis you wish to use, and raise your hand for me to check.

Warm-UpDefine learning in your own words.How do you know if learning has occurred?Do you think that learning can happen by accident

or does it have to be intentional Explain your answer.

OBJ: SWBAT identify and describe the process of classical conditioning.Relevance: Today we are learning about this because classical conditioning is one of the main ways people acquire knowledge about the world around them.

DOL: On a piece of paper answer the following

1. What is my hypothesis?2. Why do I think this?3. What are my variables?4. How am I going to measure these?

4b: what materials do I need to bring with me?5. Who is my population?6. Who is my sample?

*You may take a picture of this on your phone to refer to, and then immediately put your phone back away.

Learning

Learning: a relatively permanent change in behavior that arises from practice or experience

According to cognitive psychologists: learning may be a mental change Does not have to be a change in behavior

Learning we will study: Classical Conditioning Operant Conditioning Latent Learning Observational Learning

VideoWe are going to watch a short video.Answer the following questions:

1. What did Pavlov originally want to study?2. Why wasn’t he able to find exactly what he

wanted? 3. Explain how classical conditioning can be

called natural learning. What conclusions did Pavlov come to concerning classical conditioning?

Classical Conditioning

It all started with:

Ivan Pavlov

Classical conditioning: When your brain and nervous system make an association between 2 stimuli (thing).Example: food and a bellA song and making out with your “friend”

What is classical conditioning?

Unconditioned Stimulus (UCS): a stimulus that naturally and automatically triggers a response.

Unconditional Response (UCR): the unlearned, naturally occurring response to the UCS.

Vocab-Terms to know

Conditioned Response (CR): the learned response to a previously neutral stimulus.

Conditioned Stimulus (CS): an originally irrelevant stimulus that, after association with the UCS, comes to trigger a response.

Neutral Stimulus (NS) a stimulus which initially produces no specific response other than provoking attention. When with an unconditioned stimulus, the neutral stimulus becomes a conditioned stimulus.

Break it down

What is the NS, UCS, UCR, CS, CR?

Examples

Every time someone flushes a toilet in the apartment building, the shower becomes very hot and causes the person to jump back. Over time, the person begins to jump back automatically after hearing the flush, before the water temperature changes.

Unconditioned stimulus Hot Water

Unconditioned Response Jumping back

Conditioned Stimulus Toilet Flush

Conditioned response Jumping back to toilet flush alone

Examples

You eat a new food and then get sick because of the flu. However, you develop a dislike for the food and feel nauseated whenever you smell it.

Unconditioned stimulus flu

Unconditioned Response nausea

Conditioned Stimulus New food

Conditioned response Nausea to smell of new food

Warm Up 1/24

Explain Classical Conditioning in your own words.

Examples

5. An individual receives frequent injections of drugs, which are administered in a small examination room at a clinic. The drug itself causes increased heart rate but after several trips to the clinic, simply being in a small room causes an increased heart rate.

Unconditioned stimulus Drug

Unconditioned Response Increase in heart rate

Conditioned Stimulus Waiting room

Conditioned response Increase heart rate to new waiting room

John Watson conducted an experiment with a boy named Albert in which he paired a white rat with a loud, startling noise. Albert now becomes startled at the sight of the white rat.

Unconditioned stimulus Drug

Unconditioned Response Increase in heart rate

Conditioned Stimulus Waiting room

Conditioned response Increase heart rate to new waiting room

Think/Pair/ShareWhat is an example of classical conditioning

that you have seen before in your lives. Write in your notes

John Watson conducted an experiment with a boy named Albert in which he paired a white rat with a loud, startling noise. Albert now becomes startled at the sight of the white rat.

What are the following?Unconditioned stimulusUnconditioned ResponseConditioned StimulusConditioned response

Extinction

Extinction- a procedure in which stimuli lose their ability to evoke responses because the events that followed the stimuli no longer occur

example: bell without the trigger of food; if a child learns to associate the sound of a car pulling in a

driveway with the sound of their mom coming home, they may establish a response of joy. If the parent begins taking the bus, and the only sound of a car pulling in a driveway is that of their neighbors (not followed by entrance of the mom, then the CR of joy to the sound will eventually go away

extinction

What do you think would happen if a day or two after extinction, the tone was sounded again?

Spontaneous recovery

The recurrence of an extinguished response as a function of the passage of time

Little Albert / Generalization

Read the half sheet on the famous Little Albert experiment

Little Albert was only conditioned to fear rats. Yet, he grew to fear ___________.-he did not learn to fear these, he showed generalization

Generalization- In conditioning, the tendency for a CR to be evoked by stimuli that are similar to the stimulus which the response was conditioned (people can show a learned response to something similar to the CS)

Discrimination

Discrimination- the tendency for an organism to distinguish between a conditioned stimulus and similar stimuli that do not forecast an unconditioned stimulus (ie: Little Albert could have discriminated against the other white objects with training) Circles and Squares before food

Counterconditioning

One complaint with the Little Albert experiment, is that he was not counterconditioned.

Counterconditioning- a fear reduction technique in which pleasant stimuli are associated with fear-evoking (fear causing) stimuli so that the fear-evoking stimuli lose their aversive (avoidance-causing) qualities

Counterconditioning

Example: Little Albert given cookies, a bunny in the corner of the room. Eventually the bunny could get closer and closer until eventually the bunny could be in Little Albert’s lap while he eats cookies (fear gone)

**This would be systemic desensitization.

Flooding- fear evoking stimuli presented without actual harm. Presented all at once.

Bell and Pad treatment

For children who do not wake up to the sensation of bladder tension, this treatment can work:Child is given a special sheetWhen child wets bed, a circuit closes, and a bell goes

off.Bell wakes childEventually the Stimulus of a tight bladder wakes the

child

**This shows that classical conditioning can be learned without someone knowing

Think-Pair-write-share: What is the UCS? UCR? CS? CR?

DOL

1. What is extinction? What process happens for extinction to occur?

2. Explain what spontaneous recovery is?3. Compare generalization and

discrimination.4. How might Watson have

counterconditioned Little Albert? Be specific.

Give an example of how each of these could be used to overcome a fear.

OBJ: SWBAT identify and describe the process of operant conditioning. Relevance: Today we are learning about this because operant conditioning is one of the main ways people acquire knowledge about the world around them.

What is Operant Conditioning?

Operant Conditioning - The theory that behaviors are a result of reinforcements and punishments.

Is this experiment realistic? Do you think it could work? What could you change to make it better?

ReinforcerAny event that STRENGTHENS the

behavior it follows.

Two Types of Reinforcement:

Positive and Negative

Reinforcement

Reinforcement – an event that increases the probability that a response will be repeated (**increases behavior)

Positive Reinforcement – giving something good to increase a behavior

Negative Reinforcement – taking away something bad to increase a behavior

CFU: Provide an example of positive and negative reinforcement.

Positive Reinforcement

Strengthens a response by presenting a stimulus after a response.

Negative Reinforcement

Strengthens a response by reducing or removing an aversive stimulus.

PunishmentPunishments- Reduce behavior positive punishment –(passive avoidance)

giving something bad to reduce a behaviornegative punishment – (omission training)

taking away something good to reduce a behavior

CFU: Provide an example of positive and negative punishment.

ANSWER CHOICES ARE:1. POSITIVE PUNISHMENT2. NEGATIVE PUNISHMENT

3. POSITIVE REINFORCEMENT4. NEGATIVE REINFORCEMENT

The following are examples of what???

Spanking a child for writing graffiti on your car

door.

Giving candy for correct answers.

Taking away cell phone privileges because of low

grades.
