Scent of fear impacts cognitive performance

"It is
well-documented in the research literature that animals experiencing stress and fear produce chemical warning
signals that can lead to behavioral, endocrinological and immunological changes in their fellow animals of the same
species, but we wanted to see if this applies to humans as well," said principal investigator Denise Chen, assistant
professor of psychology at Rice.

So far, in every human study I've seen, the
findings from other animals predictably extend to humans.

Stress response and cortisol

"Our
findings indicating that elevated glucocorticoid levels in the context of a fearful situation turn down fear
symptoms in phobic subjects suggests that cortisol release may represent an adaptive response."
If the
response is adaptive, then repeated "fear" conditions would result in an attenuated cortisol response, which would
be likely to also be manifest in less metabolized DHEA "fear scent." Perhaps what doesn't kill us, provides us with
increased pheromonal appeal via increased androsterone/etiocholanolone ratios.
