In a University of Missouri study, girls and boys started grade school with different approaches to solving arithmetic problems, with girls favoring a slow and accurate approach and boys a faster but more error prone approach. Girls´ approach gave them an early advantage, but by the end of sixth grade boys had surpassed the girls. The MU study found that boys showed more preference for solving arithmetic problems by reciting an answer from memory, whereas girls were more likely to...

A new study calls into question whether a popular theory behind the dearth of women in mathematic fields is accurate, concluding that the theory had major methodological flaws, utilized improper statistical techniques, and lacked scientific evidence of the stereotype that “men are better at math.” The theory, known as the “stereotype threat”, was first published in 1999 in the Journal of Experimental Social Psychology. It postulates that women are worse than men in...

 For the past 2 million years, the size of the human brain has tripled, growing much faster than other mammals. Examining the reasons for human brain expansion, University of Missouri researchers studied three common hypotheses for brain growth: climate change, ecological demands and social competition. The team found that social competition is the major cause of increased cranial capacity.To test the three hypotheses, MU researchers collected data from 153 hominid (humans and our...

Over thousands of years, humans have evolved to naturally understand things like facial expressions and social interactions. But a University of Missouri researcher has found there is an ever-widening gap between what humans can naturally learn and what they need to learn to be successful adults in today's modern society. Schools have traditionally helped bridge the gap between evolution and new knowledge, but in the U.S. more may need to be done."Schools need to push children to learn things...
