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

What do lotus flowers, soap bubbles, and aerated chocolate have in common? They may seem innocuous, even pleasant, but each of these items is a trigger for people who report suffering from trypophobia, or the fear of holes. For trypophobes, the sight of clusters of holes in various formations can cause intensely unpleasant visceral reactions.

New research from psychological scientists Geoff Cole and Arnold Wilkins of the University of Essex suggests that trypophobia may occur as a result of a specific visual feature also found among various poisonous animals. The findings are published in Psychological Science, a journal of the Association for Psychological Science.

"These findings suggest that there may be an ancient evolutionary part of the brain telling people that they are looking at a poisonous animal," says Cole.

Trypophobia is widely documented by sufferers on the Internet and, in one study, Cole and Wilkins found that about 16% of participants reported trypophobic reactions. Despite this, there has been little scientific investigation of the phenomenon, leading Cole to refer to trypophobia as "the most common phobia you have never heard of."

Cole and Wilkins, both vision scientists, wondered whether there might be a specific visual feature common to trypophobic objects.

They compared 76 images of trypophobic objects (obtained from a trypophobia website) with 76 control images of holes not associated with trypophobia. After standardizing various features of the images, the researchers found that the trypophobic objects had relatively high contrast energy at midrange spatial frequencies in comparison to the control images.

Why might this unique visual feature lead to such aversive reactions? One trypophobia sufferer provided Cole with a clue: He had seen an animal that caused him to experience a trypophobic reaction.

The animal in question, the blue-ringed octopus, is one of the most po
