That`s why so few poor black youths grow up to be rappers.

By the time a poor child is 1 year old, she has most likely already fallen behind middle-class children in her ability to talk, understand and learn. The gap between poor children and wealthier ones widens each year, and by high school it has become a chasm. American attempts to close this gap in schools have largely failed, and a consensus is starting to build that these attempts must start long before school — before preschool, perhaps even before birth.
Up to eight months and 29 days before birth, but not a day sooner!
There is no consensus, however, about what form these attempts should take, because there is no consensus about the problem itself. What is it about poverty that limits a child’s ability to learn? Researchers have answered the question in different ways: Is it exposure to lead? Character issues like a lack of self-control or failure to think of future consequences? The effects of high levels of stress hormones? The lack of a culture of reading?
A poor child is likely to hear millions fewer words at home than a child from a professional family. And the disparity matters.
Another idea, however, is creeping into the policy debate: that the key to early learning is talking — specifically, a child’s exposure to language spoken by parents and caretakers from birth to age 3, the more the better. It turns out, evidence is showing, that the much-ridiculed stream of parent-to-child baby talk — Feel Teddy’s nose! It’s so soft! Cars make noise — look, there’s a yellow one! Baby feels hungry? Now Mommy is opening the refrigerator! — is very, very important. (So put those smartphones away!)
The idea has been successfully put into practice a few times on a small scale, but it is about to get its first large-scale test, in Providence, R.I., which last month won the $5 million grand prize in Bloomberg Philanthropies’ Mayors Challenge, beating 300 other cities for best new idea. In Providence, only one in three children enter school ready for kindergarten reading.
When I entered kindergarten, not only was I not ready for kindergarten reading, but there was no reading in kindergarten. At some point during kindergarten, I learned how to read at home, and happily read for a couple of weeks. But then I got bored with reading and went back to poking things with sticks or whatever it was I found more fascinating. When I started first grade, the educationally system started to teach me how to read, and I picked it up within a couple of weeks.
The city already has a network of successful programs in which nurses, mentors, therapists and social workers regularly visit pregnant women, new parents and children in their homes, providing medical attention and advice, therapy, counseling and other services. Now Providence will train these home visitors to add a new service: creating family conversation.
The Providence Talks program will be based on research by Betty Hart and Todd R. Risley at the University of Kansas, who in 1995 published a book, “Meaningful Differences in the Everyday Experience of Young American Children.” (see here for a summary.) Hart and Risley were studying how parents of different socioeconomic backgrounds talked to their babies. Every month, the researchers visited the 42 families in the study and recorded an hour of parent-child interaction. They were looking for things like how much parents praised their children, what they talked about, whether the conversational tone was positive or negative. Then they waited till the children were 9, and examined how they were doing in school. In the meantime, they transcribed and analyzed every word on the tapes — a process that took six years. “It wasn’t until we’d collected our data that we realized that the important variable was how much talking the parents were doing,” Risley told an interviewer later.
All parents gave their children directives like “Put away your toy!” or “Don’t eat that!” But interaction was more likely to stop there for parents on welfare, while as a family’s income and educational levels rose, those interactions were more likely to be just the beginning.
The disparity was staggering. Children whose families were on welfare heard about 600 words per hour. Working-class children heard 1,200 words per hour, and children from professional families heard 2,100 words. By age 3, a poor child would have heard 30 million fewer words in his home environment than a child from a professional family. And the disparity mattered: the greater the number of words children heard from their parents or caregivers before they were 3, the higher their IQ and the better they did in school. TV talk not only didn’t help, it was detrimental.
Hart and Risley later wrote that children’s level of language development starts to level off when it matches that of their parents — so a language deficit is passed down through generations. They found that parents talk much more to girls than to boys (perhaps because girls are more sociable, or because it is Mom who does most of the care, and parents talk more to children of their gender).
This might explain why young, poor boys have particular trouble in school. And they argued that the disparities in word usage correlated so closely with academic success that kids born to families on welfare do worse than professional-class children entirely because their parents talk to them less. In other words, if everyone talked to their young children the same amount, there would be no racial or socioeconomic gap at all. (Some other researchers say that while word count is extremely important, it can’t be the only factor.)
But those researchers are obviously wrong, and probably racist.
While we do know that richer, more educated parents talk much more to their children than poorer and less educated ones, we don’t know exactly why. A persuasive answer comes from Meredith Rowe, now an assistant professor at the University of Maryland. She found that poor women were simply unaware that it was important to talk more to their babies — no one had told them about this piece of child development research. Poorer mothers tend to depend on friends and relatives for parenting advice, who may not be up on the latest data. Middle-class mothers, on the other hand, get at least some of their parenting information from books, the Internet and pediatricians. Talking to baby has become part of middle-class culture; it seems like instinct, but it’s not.
If you haven’t heard of Hart and Risley’s work, you are not alone — and you may be wondering why. These findings should have created a policy whirlwind: Here was a revolutionary way to reduce inequities in school achievement that seemed actually possible. How hard could it be to persuade poor parents to talk to their children more? ...
Providence has the money to be more ambitious. The city plans to begin enrolling families in January, 2014, and hopes to eventually reach about 2,000 new families each year, said Mayor Angel Taveras. It will most likely work with proven home-visitation programs like the Nurse-Family Partnership. The visitors will show poor families with very young children how to use the recorders, and ask them to record one 16-hour day each month.
Every month they will return to share information about the results and specific strategies for talking more: how do you tell your baby about your day? What’s the best way to read to your toddler? They will also talk about community resources, like read-aloud day at the library. And they will work with the family to set goals for next month. The city also hopes to recruit some of the mothers and fathers as peer educators.
And when that fails, what`s next? Intensive pre-pre-schools where Brown U. grads will be employed to speak to black babies using words they learned getting their Brown degrees like "intersubjectivity" and "phallocentrism?"

Meanwhile, Steve "Freakonomics" Levitt and Roland Fryer of Harvard have finally, after a half dozen years, found a journal to publish their old study showing that black babies have higher IQs than Asian babies at eight months to twelve months. Of course, they don`t actually have an IQ test for infants, but their little test of baby liveliness is practically just as good! See the comments on Marginal Revolution for a discussion.
