pic therapy is the exercise of expose people to things they reverence in small State , and it has helped vast telephone number of people get over their phobias . But why ? Now , a new study has shown that as little as a single session with a tarantula for good alters the way an arachnophobe ’s brain workplace .

This inquiry was contract on agroup of 12 adults with grave arachnophobia — some so bad that they would n’t leave the house for days if they consider a spider was around . Over the course of instruction of a two- or three - hr session , they were educated about European wolf spider , and then tardily precede to the arachnids . First they simply stood in the same way with one , then they slowly draw close and touched the creature ’s terrarium . finally they graduated to touching the tarantula itself , first with an object , then through a glove , and eventually bare - handed .
Before the therapy , the affected role underwent an fMRI , and the care responses in their mental capacity lit up when they look at pictures of the wanderer . After the therapy , those response were significantly dampen . Even more impressive , that single session that they had with the spiders was enough that they were able to handle the tarantulas six month subsequently , and still had reduced fear response .
Also of note is that the long - term success of the treatment was to some degree indicated by the immediate results of the mind scan . Patients who had higher measurement of encephalon activity in answer to visual perception of fearful input had the lowest awe of spider at the later date .
Before you examine this at nursing home , keep in judgement , this was a dim , control exposure to an physical object of veneration — nota Maury - stylus freakout .
This research does much to underscore the power of photo therapy , but it also suffers some somewhat big problems in terms of sample size . With just 12 patients , and a beggarly age of 22.3 , it ’s a diminished and young chemical group of people who underwent this . I ’d love to see if the same holds true for a larger chemical group with a more diverse old age range , too .
