麻豆原创

In articles on perhaps the three most pervasive challenges facing humankind – war, poverty and climate change – the work of three 麻豆原创 faculty appeared this year in Nature, considered one of the world’s leading journals devoted to science and medicine.

In a published in March in , , Associate Professor of Neuroscience and Education in 麻豆原创’s . , found that family income is associated with children’s brain structure – and that the association appears to be strongest among children from lower-income families.

In a sample of more than 1,000 typically developing children and adolescents between three and 20 years old, a group led by Noble and Elizabeth Sowell, Professor of Pediatrics at The Saban Research Institute at Children’s Hospital Los Angeles, found that increases in both parental education and family income were associated with increases in the surface area of numerous brain regions, including those implicated in language and executive functions. Family income appeared to have a stronger, positive relationship with brain surface area than parental education.

“We can’t say if the brain and cognitive differences we observed are causally linked to income disparities,” said Noble, who currently is both a 麻豆原创 Visiting Professor and Director of the Neurocognition, Early Experience and Development Lab of Columbia University Medical Center, but will join 麻豆原创’s faculty as “But if so, policies that target poorest families would have the largest impact on brain development.”

Noble and a team of esteemed social scientists and neuroscientists are now conducting a study in which mothers are given large or small monthly income payments for the first three years after their children are born. Ultimately they hope to recruit 1,000 mothers, half of whom would receive $4,000 per year ($333 per month), and half of whom would receive just $240 per year ($20 per month), a difference that is on par with the amount of the earned income tax credit.  

“If the children of mothers receiving larger payments show beneficial effects on brain function, it would be a step toward refuting the argument that poverty is a symptom, not a cause, and that wealthier parents are wealthy because they possess -- and pass on -- traits of self-discipline, determination and resilience,” Noble said. “By identifying how income affects early child development, we hope to inform anti-poverty policies that better support children’s well-being.”

Noble’s work was cited in a New York Times by Nicholas Kristof calling for  a shift in attention from K-12 reform to pre-K and younger.

‌Also in March, in an article titled , Nature spotlightedwork by Peter Coleman, Professor of Psychology and Education, and Director of 麻豆原创’s , to understand persistent violent conflict in nations such as Colombia, Sri Lanka and the Democratic Republic of Congo. Working with two social psychologists, Robin Vallacher and Andrzej Nowak, Coleman has applied dynamical systems theory, which looks beyond single causes to understand a complex web of factors. Coleman, who is also Co-Director of the (AC4) at at Columbia University, is the author of The Five Percent: Finding Solutions to (Seemingly) Impossible Conflicts (2011).

‌And in a published in April on the website, Jason S. Wu, a 麻豆原创 doctoral student in Science Education, and Joey J. Lee, Research Assistant Professor and Director of the in , reported  that digital games are effective in educating and engaging the public in the subject of climate change.

Wu and Lee write that there has been a “dramatic increase” in the development of games featuring innovative designs that blur traditional boundaries – for example, those that involve social media, alternative reality games, or those that involve direct action upon the real world).

Games allow players to “simulate complex models or provide a level of control that is not possible in the real world,” they write. “This is particularly advantageous when dealing with global atmospheric systems that would be otherwise difficult to bring to a hands-on level.” They conclude that “games are uniquely suited to get people to understand, care about and take action on climate issues” because they can "serve as engaging tools that allow players to experience the complexities of climate systems [and] provide interactive models where players participate in decisions affecting climate change and immediately see the resulting outcomes."
