In one of the first such studies that took place between 1966 and 1977, for example, less than 1% of the study's 5000 children drew a woman when asked to draw a scientist.
Evidences of the new research have been disclosed in the bimonthly academic journal - Child Development. From the 1980s onwards, an average of 30% of girls and 83% of boys aged 6 sketched male scientists.
A team of researchers from the Northwestern University conducted the research suggesting that the stereotypes of children that link men with science seemed to be weakened by the time.
This is in line with increased numbers of women in science, and more depictions of female scientists on TV and in other children's media.
This shift in perception is probably the result of an increasing number of women becoming scientists, and mass media - such as television shows and children's magazines - featuring female scientists more often, says lead author David Miller, a psychology researcher at Northwestern University in Evanston, Illinois. "However, the tendency to draw male scientists did increase strongly during elementary school and middle school".
By 2015, women earned 48 percent of all chemistry degrees.
Less than one-fifth of bachelor's degrees in computer science are awarded to women, despite the fact that 60 percent of bachelor's degrees go to female graduates.
"Women are still underrepresented in some fields, so it makes sense that children exposed to that environment are still reproducing those stereotypes", Miller says.
Alice Eagly, study co-author, professor of psychology at the Weinberg College of Arts and Sciences of the Northwestern University and a faculty member of Policy Research with the University's Institute said that, "Our results suggest that children's stereotypes change as women's and men's roles change in society. It's more getting at these associations that children have". "Prior studies have suggested that these gender-science stereotypes could shape girls" interests in science-related activities and careers'.
Researchers at Northwestern University in the USA examined the results of 78 studies, which together involved more than 20,000 United States children.
