A “phobia” is an irrational fear. Many of the stimuli that produce a phobic response, such as a fear of spiders, actually have an evolutionary basis that biologically prepares humans to fear them. A team of investigators at the Institute for the Developing Mind at Children’s Hospital Los Angeles recruited¬†21 spider-phobic and 21 non-phobic control participants, all young adult women, to learn more about phobic reponses and the brain. The researchers¬†found that exposure to phobic images without conscious awareness is more effective than longer, conscious exposure for reducing fear.
