Excerpt from article

summary:

"...in humans, fear
chemosignals facilitated overall accuracy in identifying word
relatedness

independent of the perceived olfactory qualities
of the smells. We have also suggested that the effect

arises
from a learned association including greater cautiousness
and concomitant changes in cognitive

strategies."
