The Sky is Not the Limit



Does crossing bridges make you scared?  Does flying in planes give you anxiety?  How about standing on high up balconies or riding roller coasters?  Personally, these things are some of my worst nightmares due to my fear of heights.  A condition called acrophobia is known as an extreme fear of heights.  But why isn't everyone scared of heights? 

Acrophobia is one of the most common phobias in the United States, as well as across the globe.  But what causes some people to have this fear and others to be perfectly fine performing any of the activities mentioned above.  After researching, I found a recent study performed by psychologist Russell Jackson that explains a potential reason why this happens to some, but not all. 

Jackson's study began by surveying students through psychological questions to gauge their acrophobia level.  From the results of this survey, he chose 43 students to test further.  The study asked each volunteer to approximate the height of a five-story, 14.4-meter parking garage, with test subjects located at the top or bottom of the building.  Results showed that errors were made by subjects both on top and bottom of the building, even though the subjects should have technically erred more from up top because of their fright.  This made the psychologist believe that those that have acrophobia may suffer from this because of an issue with perception of vertical dimensions.   The misperception of heights can cause acrophobiacs who see a 14-meter building like it is 50 meters to react like normal people would to a 50-metre building and therefore seem more scared of heights than the average person.

After reading about this study, the idea of misperception of height seemed like a perfect reason for acrophobia.  I believe the next question scientists would have to investigate would be why certain people have this misperception.  Is it something in the brain that causes it?  Or is it another psychological issue?  Is acrophobia genetic? Do parents pass the fear along to their children?  Answering questions, such as these, may help get a better understanding of acrophobia and perhaps can help find a "cure" of some sort to help those many people finally face their fear of heights!





This is actually a very interesting topic. My dad has a very big fear of heights where I happen to love them. I definitely don't think that a fear of something could be genetic but your parents could influence how you feel about something. So I did some research and found that there's actually a way to cure Acrophobia. This article has 5 steps to overcoming your fear!

The site I found briefly mentions some answers to your questions. At a young age babies learn a fear of heights because of experience. A baby will crawl off the edge of a couch or fall off a bed and eventually learn to perceive when there is a drop off. Gibson and Walk's Visual Cliff study supports the idea that this is a learned skill. If a child has a traumatic fall at this young age, this could later result in a phobia of heights. Also, children might learn to be deathly afraid of heights when they see their parents react to them in a similar manner. I don't think it is something wired in our brains when we are born that we are officially afraid or not afraid of heights, but rather it is a learned fear through parental guidance or fatal falls.
