absolute threshold

What does absolute threshold have to do with smelling armpits? Well, when I think of a.t. I think of the examples that ask how many drops of perfume are necessary in order to perceive the odor of the perfume (or cologne? Smelling armpits is one way to test the perfume...which odor is stonger? The body's odor or the perfume made to mask the body's odor. How about those people who obviously have a high absolute threshold because they need lots of perfume (or maybe their body odor is just worse). Maybe it has something to do with sensory adaptation. But that would mean another picture because that is another psych vocab word.

absolute threshold-the minimum stimulation needed to detect a particular stimulus 50 percent of the time.
