This question is incomplete. I've found the complete question online. It is as follows:
Jennifer is a chain smoker. When her friend Irene, a non-smoker, gets in the car with Jennifer she is overwhelmed by the smell of smoke. One day she mentioned this fact to Jennifer, who was surprised by the comment. Jennifer claims that when she sniffs her hair and clothing she can't sense the smoky smell. Jennifer's inability to detect the smell is an example of _____.
A. perceptual redundancy.
B. sensory adaptation.
C. the cocktail party phenomenon.
D. closure.
Answer:
The correct option is letter B. sensory adaptation.
Explanation:
Sensory adaptation refers to the change our sensory receptors undergo when exposed to a constant stimulus. Since Jennifer is constantly exposed to the smell of the smoke, she can no longer smell it in her hair and clothing. Her receptors got used to the stimulus and no longer react to it. It is the same thing that happens to any of us when we enter a bakery, for instance. We immediately identify the smell of bread, bagels etc. But after just a few minutes inside the bakery, our receptors get used to the stimulus and we no longer smell baked goods.
