Transcript of Ivan Pavlov_s Classical Conditioning Theory
-
Close your eyes:
Think about your favorite food (green mango with vinegar, salt and bagoong)Is your mouth watering?If so, its because you are conditioned
-
Pavlov, a Russian physiologist, first described classical conditioning in 1899 while conducting research into the digestive system of dogs. He was particularly interested in the role of salivary secretions in the digestion of food and was awarded the Nobel Prize for Medicine or Physiology in 1904.
-
Stimulus- some action that produces activity in an organismResponse- reaction of an organism to a stimulusAssociationsmental connections between two stimuli
-
Form of learning where 1 stimulus (thought of food) creates a response (mouth watering) in response to another stimulus(actual food)
This occurs when the two stimuli have been associated with each other

-
He knew that dogs would salivate when meat was placed on the tongue because salivation aids in digestionHe discovered that dogs began to salivate before they received the meat
WHY???
-
Because the dogs had learned from experience that people entering the labs clinking of food trays meant that food was comingCould they learn to salivate to any stimulus that signaled meat???
Pavlov thought yes, so he had to prove it
-
Rang a bell, then put meat powder on dogs tongueDog began to salivate in response to meat powder
Pavlov repeated this several times
-
He rings the bell but does not follow it with meatDogs salivated anyway
They learned to salivate to the bell alone
-
US=Unconditioned Stimulus
A stimulus that causes a response that is automatic, not learnedeg. Food
-
UR=Unconditioned Response
Automatic responseeg. Salivation
-
