Have you ever looked at yourself in a full-length mirror and wished you looked more like the beautiful people who grace the covers of glossy magazines? If so, you are by no means alone.
Body dissatisfaction is so prevalent that some academics have referred to it as “normative discontent”. Many of those affected not only feel dissatisfied with their bodies, they actually believe they are heavier than they really are – a phenomenon known as body size misperception.
Our recent study found that people’s perception of their own and others’ body weight could change in as little as two minutes.
Participants were asked to view images of people that had been digitally manipulated to appear lighter or heavier than they actually were and decide whether these images looked fatter or thinner than “normal”.
After 120 seconds of exposure to manipulated thin bodies, the original-sized body images looked abnormally large to participants while the thinner images were rated as normal.
The opposite was also true: exposure to heavier bodies made participants see original body sizes as skinny.
Chasing the thin ideal
It is hardly news that many are negatively affected by the thin, supposedly ideal images propagated by the media.
The connection between social pressure to be thin exerted by these images and feelings of body dissatisfaction – a risk factor for developing eating disorders such as anorexia nervosa – was first made by German psychologist Hilde Bruch in the 1970s.
Then, in 1980, a study showed that the measurements of Miss America contestants and Playboy centrefold models between 1959 and 1979 were decreasing, supporting claims that the media’s “thin is beautiful” message was spreading.
Although many studies in the intervening decades have confirmed this link, there is still relatively little understanding of the brain mechanisms underlying the perception of our own bodies in relation to what we see on TV and in magazines.
