In an experiment investigating whether people can train their sense of smell, participants were repeatedly exposed to a particular class of odors (floral or minty). As a result of this repeated exposure, _____.
A)the participants improved their ability to distinguish subtle differences among different scents
B)the level of human chemosignals produced by the sweat glands increased in the participants
C)participants became less able to distinguish subtle differences among different scents
D)most participants developed an aversion to this particular class of odors (floral or minty)

Question

Quizplus · Accepted Answer

The repeated exposure to a particular class of odors (floral or minty) is an example of sensory adaptation or habituation. This type of exposure can lead to improved sensory discrimination or the ability to distinguish subtle differences among different scents. Therefore, option A is correct. Option B is incorrect because the production of human chemosignals is not related to the experiment's objective. Option C is also incorrect as repeated exposure usually leads to increased sensitivity, not decreased sensitivity. Option D is irrelevant because the experiment does not relate to aversion.
