Why men love cars again?

Not surprisingly, among many toys, girls will choose dolls, and boys will not hesitate to choose cars. But this is not because society encourages girls to foster care, and boys tend to be more active. Recently, scientists have found an answer to this problem.

According to Live Science, scientists conducted monkey studies in 2002 and 2008 to provide a biological explanation for the choice of favorite sex toys between the sexes. In this experiment, the male monkeys also had the hobby of choosing toys as cars, while the female monkeys chose dolls. So which biological factors stipulate preferences that are specific about this gender?

New research shows that babies are exposed to hormones while they are still in the fetal stage, and this makes them have separate preferences right after birth. Scientists have not yet explained this, but toys such as dolls or trucks can help boys and girls develop the skills needed to perform their gender roles.

Experiments on monkeys also showed that male monkeys also chose
Select the toy car, while the female monkey selects the doll.

In the 2009 study, Gerianne Alexander, a professor of psychology at Texas A&M University and her colleagues, found that the male hormonal level of 3 to 4 months is correlated with time. Children spend time looking for typical toys for boys like trucks. The same is true of female hormones and the time when girls look for typical toys for girls like dolls.

Kim Wallen, a psychologist at Emory University, who also researched on the topic, said: 'The outstanding thing that the data collected shows that there is a difference in choosing toys between two sexes happen very early in life, before it is capable of being socialized '.

The idea that this difference is a hormonal product is further strengthened when British scientists, 2011, discovered that girls experience abnormally high levels of male hormones when In the womb, there is a hobby of playing typical toys for men.

But why do male hormones create a tendency to choose trucks as trucks? The common explanation is that these toys facilitate powerful operations. However, research in 2009 shows that the preference for boys and girls has been available since they haven't started playing toys yet.

Just three months old, boys focused on looking at toys that are related to their gender. Wallen also said it was difficult to explain this.
