The Wall Street Journal recently ran an on 鈥淏aby鈥檚 First Year,鈥� the $16 million study co-led by Teachers College neuroscientist Kimberly Noble that is seeking to determine whether poverty directly inhibits brain development in very young children. Noble, who is Associate Professor of Neuroscience & Education, and her co-workers are testing this idea by giving new mothers cash payments to see whether supplemented income fosters the growth of their babies鈥� brains and cognitive abilities.
鈥淭here clearly is some genetic basis to cognitive development,鈥� Noble says in the story. 鈥淭here鈥檚 also good evidence to suggest that experience plays a role in cognitive, intellectual development. We are manipulating that experience.鈥�
The Journal notes that while 鈥減ast studies have found correlations between income and brain growth鈥his project aims to show a causal link, in hopes its findings could affect social policy.鈥�
In the story, Noble speculates about how, specifically, poverty negatively affect babies.
鈥淲hen a mom is less worried about how she鈥檚 going to pay rent or keep the lights on, she鈥檚 more likely to be present with her children,鈥� she says. 鈥淪he鈥檚 more likely to be able to engage in warm and nurturing parenting.鈥� Low-income families also face difficulties getting high-quality medical care and nutritious food, she notes. And, she says, the toxic stresses of poverty could inhibit brain development.

Conversely, Noble says, income supplements could enable mothers to afford more books and transportation to services and health care, or to stay home from work longer to bond with their babies.
The story reports that about 860 women have signed up so far, reporting an average yearly income of about $18,000 before the study.
In the story, scholars at both the Brookings Institute and the American Enterprise Institute speculate on the ultimate findings. Isabel Sawhill, a senior fellow at Brookings, says the study 鈥渨ill get huge attention when it comes out.鈥�
Noble recently gave a on the study that has received more than 1.1 million views.
