What are the impacts of the different division of labor between men and women? There are significant visual differences between men and women: women are better at recognizing colors than men, while men's visual advantages are reflected in their sensitivity to detail of distant objects and their ability to track rapidly moving objects.
Researchers say this difference arises because men and women have different roles in long-term social division since ancient times. Male vision is weaker in resolving color shapes in the middle of the spectrum, such as blue, green, and yellow.
The world may really be different in the eyes of men and women, with women being more sensitive to color, while men's visual advantage lies in their ability to distinguish and track objects. Research leader Israel Abramov and his research team conducted a series of experiments on a group of adult male and female volunteers with normal vision in this study.
In color related tests, male and female volunteers describe different shapes of the same object. "In the vast majority of the visible spectrum, men require longer wavelengths than women to form the same chromaticity in the eyes," the researchers said. The research team published their findings in the latest issue of the journal Gender Biology.
Generally speaking, the wavelength of warm colors is longer, such as orange, red, and other colors. The same red color will appear more red for men, while the same green color will appear more green for women. Men will feel a bit yellow when they see the green color. The results also show that male vision is weaker in resolving color shapes in the middle of the spectrum, such as blue, green, and yellow.
Men's visual strengths are manifested in detecting detailed changes in distant objects, especially when tracking smaller objects or light emitting objects. The research team found that these differences are caused by differences in the development of neurons in the visual cortex, which is dominated by hormone secretion. Men have higher levels of testosterone, and they have 25% more neurons in the brain than women.
Evolving differences in social division of labor
These findings also provide strong evidence for a previous theory that men and women in ancient times evolved different psychological abilities under long-term social division roles. The research results clearly show that men are significantly more sensitive to object details and observation of object movements than women, which allows men to be more sensitive to detecting, locating, and identifying prey during hunting. Women's sensitivity to color makes them better at collecting work.
John Babu, professor of optics and vision at City University of London, said that women are less sensitive to color resolution than men. However, when it comes to identifying shapes through color, women are slightly better. Babu explained that women are much better than men when it comes to describing colors, distinguishing between colors, or showing what different colors mean.
