Transcript of Ivan Pavlov: Classical Conditioning

Ivan Pavlov: Classical Conditioning
Background Information
Physiologist Ivan Pavlov was doing a research project on the salivation of dog's digestion. The process was to see how much saliva a dog would produce when placing meat powder in the dog's mouth.

However, something unusual started to happen. Dog's that were repeatedly brought into the laboratory started to salivate before food was placed in its mouth.

Pavlov believed that the dog's actions were based on a learning process that he later named classical conditioning.

Conditioned Stimulus (CS)
- "an initially neutral stimulus that comes to elicit a conditioned response after being associated with an unconditioned stimulus" (Wade & Tavris, 2012, p. 301).

Conditioned Response (CR)
- "elicited by a conditioned stimulus; it occurs after the conditioned stimulus is associated with an unconditioned stimulus" (Wade & Tavris, 2012, p.301).
Now that we have discussed classical conditioning, I want you to look back at "The Office" altoid experiment. Explain to me, what is the neutral stimulus, conditioned stimulus, and conditioned response exhibited in the video.

After I have collected all explanations, I will comment on each and will share the correct answer with the class.
Students will be able to understand the concepts of Ivan Pavlov's Classical Conditioning.

Unconditioned stimulus (US)
"stimulus that elicits a reflexive response in the absence of learning" (Wade & Tavris, 2012, p.300).
Unconditioned response (UR)
"a reflexive response elicited by a stimulus in the absence of learning" (Wade & Tavris, 2012, p.301).
In other words, food (US) caused the dog to salivate (UR) (Figure 1). To better understand, unconditioned means that it's natural. Learning is not needed for a response to be made.
"By an unconditioned stimulus (US), Pavlov meant an event or thing that elicits a response automatically or reflexively. By an unconditioned response (UR), he meant the response that is automatically produced" (Wade & Tavris, 2012, p.301).
Neutral stimulus
- something that does not produce a response only until it is frequently paired with a unconditioned stimulus (US) (Wade & Tavris, 2012, p. 301). Then it becomes a conditioned stimulus (CS).
At first the bowl alone does not elicit any kind of response from the dog that is why it is a neutral stimulus. Once the bowl (neutral stimulus) is paired with the food (US) it will cause a salivation response (UR) from the dog (Figure 2). Once an association is made, the bowl alone (CS) will elicit a salivation response (CR) without the presentation of the food (Figure 3).

Figure 2: A neutral stimulus and a US leads to a UR (Wade & Tavris, 2012, p.301).

The Office
(Stanley, 2012)
"The signt or smell of the food, the dish in which the food was keept, and even the sight of the person who delivered the food were enough to start the dog's mouth watering" (Wade & Tavris, 2012, p. 300)
