Fear of holes may stem from evolutionary survival response
Date:9/2/2013

isonous animals in the world, which led Cole to a "bit of a Eureka moment."

He and Wilkins analyzed images of various poisonous animals including the blue-ringed octopus, deathstalker scorpion, king cobra snake, and other poisonous snakes and spiders and found that they, too, tended to have relatively high contrast at midrange spatial frequencies.

In light of this, the researchers speculate that trypophobia may have an evolutionary basis clusters of holes may be aversive because they happen to share a visual feature with animals that humans have learned to avoid as a matter of survival.

"We think that everyone has trypophobic tendencies even though they may not be aware of it," says Cole. "We found that people who don't have the phobia still rate trypophobic images as less comfortable to look at than other images."

In studies currently under way, Cole and Wilkins are exploring whether manipulating the spectral characteristics of images of everyday objects, like watches, leads people to prefer one object over another. They believe these experiments will shed light on just how ingrained trypophobic tendencies might be.
