1. Classical Conditioning: Pavlov

2. Quick Re-Cap and H/W Check
In your group of three quiz each on:
Work out the examples on the next slide by labelling them with the correct terms.
Complete the top part of the re-cap sheet.
Go through your h/w as a group. Ask questions if you do not understand.
Complete the bottom half of the re-cap sheet.

3. UCS, UCR, NS, CS and CR
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.
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.
A boy was playing with a dog in a park when a loud noise made him jump. Now the boy jumps when he sees a dog.
Let them invent own scenario and explain to the rest of the group.

4. Key Terms
EXTINCTION
The dying out of a conditioned response by breaking the association between
the C.S. and the U.C.S. E.g. When the bell was repeatedly rang and no food
presented Pavlov’s dog gradually stopped salivating at the sound of the bell.
SPONTANEOUS RECOVERY
The return of a conditioned response (in a weaker form) after a period of time.
E.g. When Pavlov waited for a few days and then rang the bell once more the
dog salivated again.
GENERALISATION
When a stimulus similar to the C.S. also elicits a response. E.g. Initially Pavlov’s
dog salivated at the sound of any bell – not just the food bell.
DISCRIMINATION
The opposite of generalisation i.e. the ability of the subject to tell the
difference between two similar stimuli. E.g. Eventually Pavlov’s dog learns the
difference between the sound of the 2 bells and no longer salivates at the
sound of the non-food bell.

5. If a baby is ignored when it cries then he/she may stop crying.
A baby soon learns to distinguish between the voice / smell of their main carer (usually the mother) and other adults. This is an example of STIMULUS DISCRIMINATION
If a baby is ignored when it cries then he/she may stop crying.
This is an example of EXTINCTION
How could this be useful? Could this harm the baby in anyway?
DO I RESPOND DIFFERENTLY TO DIFFERENT VOICES?
WHAT IF LOTS OF PEOPLE ARE LOOKING AFTER ME?
WHAT WILL HAPPEN IF I CRY BUT NO-ONE COMES TO SEE WHAT’S WRONG?
