Mrs. Lucas/ Mrs. Manno, What’s going on? What are you doing? Can’t your teacher JUST BE NICE???

3. So why use the bell?
This was an example of something called “Classical Conditioning”
You learned over time that the sound of the bell meant CANDY!!!
Another one you might know is this image means food/French fries

4. Who started this?
A scientist named Ivan Pavlov ( ) was researching the digestive system and the effects saliva had on swallowing
He was using Dogs for his study

5. Why did he start using the bell?
Pavlov noticed that the dogs started to drool when the dogs saw his assistants lab coats.
These assistants were the ones that fed the dogs and always wore lab coats.

6. Why did he start using the bell?
The dogs had associated the lab coats with food, so thought food was on it’s way when they saw the lab coat and began to drool.
Pavlov wanted to test this idea further

11. Key Terms
Conditioned Stimulus (CS): an initially neutral stimulus that comes to produce a new response because it is associated with the US. (BELL)

12. Key Terms
