Many of these self-correct, but 1 in 25 babies have a severe head shape deformity. A flattening, known as plagiocephaly, is a relatively common condition which affects around half of all babies under the age of one to some extent. However, the main cause for flattening is lying for too long in one position. There are several reasons why the skull may flatten. Although there are many positives, this flexibility can leave the head vulnerable to skull malformation if not properly managed. This allows the baby to pass through the birth canal and into the world, while also allowing growing room for the brain to develop during childhood. What can cause an ‘abnormal’ head shape in babies?ĭuring infancy, a baby’s skull is relatively soft and mouldable. Although this is something to be celebrated, with evidence to suggest that misshapen skulls are linked to health issues such as visual defects and developmental delay, it’s important to know how to recognise what can be termed as a ‘normal’, healthy head shape and what treatment can be put in place for babies suffering from skull shape deformities. There are around 7.5 billion people on the planet and each and every one of us is different. The ideal is thought to be 20% longer than it is wide and there should be no asymmetry or difference between the left and right sides. However, naturally, the normal head shape when viewed from above should look similar to an egg, slightly wider at the back than the front. The factors that determine what is regarded as ‘normal’ vary with social and cultural values such as gender, age, ethnic origin and rank in society. The study was published in the journal Psychological Science ( Valentine et al., 2014).Normocephaly is the term used to describe a normal head shape, one that has normal dimensions and proportions within the population. The researchers took into account the age and attractiveness of the men - in other words it wasn’t just that men with wider faces (or of a certain age) were more attractive. Previous studies have found that women prefer more dominant men for short-term relationships, but almost all of these studies were based in the lab and did not involve an interaction that could actually lead to mating and dating.” “The fact that women wanted to see these men again suggests that our findings are robust - women aren’t just saying they are interested, they’re actually willing to be contacted by these men. Women were also more likely to choose them for a second date as well. They were also more likely to be chosen for a short-term relationship. Men with the widest faces (more accurately, the highest fWHR) were rated as more dominant. The study involved live speed dating in which heterosexual single people met for just 3 minutes. Our study shows it’s also a reasonably good indicator of perceived dominance - not only that, it piques women’s interest in a face-to-face speed-dating setting.” “High male fWHR has previously been associated with surviving in hand-to-hand combat, aggressiveness, self-perceived power, and CEO’s financial success. “Our study shows that within three minutes of meeting in real life, women find more dominant, wider-faced men attractive for short-term relationships, and want to go on another date with them.”įor the study, the researchers measured men’s facial width to height ratio, their fWHR. Men with wider faces are seen as more dominant and aggressive.ĭr Katherine Valentine, the study’s first author, said: The face shape is also linked to being more aggressive and higher survival of hand-to-hand combat!įor short-term relationships, women are most attracted to wider faces, research finds.
