NEW YORK, JULY 9, 2005 (Zenit.org).- Boys and girls have marked physical and psychological differences and hence they have to be educated differently. This is the thesis of a book published earlier this year by psychologist and family doctor Leonard Sax.
In “Why Gender Matters” (Random House), he takes issue with the modern tendency toward gender-neutral child-rearing. According to this theory boys and girls behave differently because of the way they are educated, or because of cultural factors. Sax describes how in the mid-1990s he began to see more and more young boys arrive at his office with requests for medication, due to their supposed attention-deficit disorder.
The real problem, Sax eventually discovered, was that the second- and third-graders were being educated by teachers who did not understand the differences in how boys and girls learn. For a start, he explains, a girl’s sense of hearing is more sensitive than that of boys, so the tone of voice used by a female teacher may be fine for the girls, but does not engage a boy’s attention.
This experience sparked off Sax’s interest in the subject of sex-based differences. His research showed that behavioral differences are not just caused by cultural factors. Research into men and women who have suffered strokes reveals that in men the left and right hemispheres of the brain are strongly compartmentalized, with the former dedicated to verbal skills and the latter to spatial functions. This division does not exist in women, who use both hemispheres of the brain for language.
And analysis of human brain tissue shows that there is a difference in its composition, at the level of the proteins. This difference is not due to hormonal changes that occur at puberty, but is something innate and is present even in children.
Sax also notes that girls and women can generally interpret facial expressions better than most boys and men. He cites research carried out at Cambridge University, showing that even young babies reveal differences in the way they pay attention to objects. Female babies are more interested in other people’s faces, while male babies prefer to pay attention to moving objects.
In fact, evidence exists that from the composition of the retina to the way images are processed by the brain, there are notable differences between males and females. This results in females being more aware of differences in color and texture, while males discern with greater facility location, direction and speed.
This difference is then reflected in the toys that young children prefer — dolls for girls and trucks for boys — and the type of pictures they draw, with girls using more colors and including more people in their drawings.
This has consequences when it comes to schooling, Sax explains. Given that most kindergarten teachers are women they tend to encourage their students to draw people and to use lots of colors. This can lead to discouragement among boys, whose different style of drawing is not appreciated by the teacher, leading them to conclude that “art is for girls.”
Male and female differences are also evident in the way people navigate. Men are more likely to use abstract concepts such as north and south, and to refer to distances. Women, by contrast, prefer using visual landmarks. Neuroscientists have found, Sax noted, that even by the age of 5 the male brain uses a different part of the brain to navigate, the hippocampus, while the female brain relies on the cerebral cortex.
Notable differences also exist in how emotions are handled. Children are generally not capable of analyzing their emotions, because this area of their brain has not yet developed. In adolescence, emotions are increasingly dealt with by the cerebral cortex, the area of the brain associated with higher cognitive functions.
But this change is far more pronounced in girls’ brains than in those of boys. So, if at school adolescents are asked by their teachers to write or talk about their emotions this places boys at a disadvantage.
Another area with marked differences between males and females is in the willingness to accept risk. Most boys enjoy taking risks, and are also impressed by other boys who take risks. This is not the same for girls, who generally are less likely to seek out risky situations just for the sake of it. Boys are also more likely to disobey their parents when told not do something risky.
