Losing Ground: Hispanic children fall behind their peers quickly, a study finds

All the studies show that Hispanic illegals and their offspring have markedly lower average IQ scores than the white average. My orientation in psychometric research has however always been great caution about the validity of any tests used and I initially felt that the remarkable success of ancient Central Americans in building rather advanced civilizations despite being cut off from the major source of human progress (the Eurasian continent) implied a higher IQ for their descendants than the tests showed.

That is however a fairly arguable proposition and the findings reported below have changed my mind. I think that the findings below confirm what the IQ tests say. The results below show what I very "incorrectly" call the "chimpanzee effect". A month old chimpanzee is much smarter and more capable than a human infant of the same age but the human does of course far surpass the chimp eventually. In other words, low IQ is less evident in the early years and most evident in adulthood. We find a similar effect in blacks. Average black IQ is closer to average white IQ in childhood than in adulthood. Beyond the early teens, black IQ stops rising but white IQ does not. White IQ peaks at about age 16.

And what is reported below is precisely another example of the chimpanzee effect: Intellectual achievement gap smallest in early childhood but rapidly increasing with age. I must stress that I am NOT saying that either blacks or Hispanics are similar to chimpanzees. ALL human beings of any race are much smarter than chimps. I am just using chimps as a vivid demonstration of what seems a general truth: That real gaps in intellectual ability become evident later rather than sooner -- and the Hispanic developmental pattern is exactly what we expect of an average IQ that is indeed lower

A forthcoming study on Hispanic children’s cognitive skills underlines the challenges the country faces in aspiring to close the achievement gap between these children and their white and Asian counterparts. Hispanic “children fall behind their peers in mental development by the time they reach grade school, and the gap tends to widen as they get older,” reports the New York Times. “The drop-off in the cognitive scores of Hispanic toddlers, especially those from Mexican backgrounds, was steeper than for other [low-income] groups and could not be explained by economic status alone. . . . From 24 to 36 months, the Hispanic children fell about six months behind their white peers on measures like word comprehension, more complex speech and working with their mothers on simple tasks.”

This new study, from the University of California–Berkeley, may be unusually blunt in its assessment of Hispanic cognitive development, but it is hardly unprecedented. A 2004 study by the California Legislative Analyst’s Office found a similar decline in Hispanic students’ ability to keep up with their peers in learning English. Children from Mandarin- and Spanish-speaking households begin kindergarten with similar levels of English proficiency, but their paths quickly diverge. The Mandarin-speaking students make continuing progress in mastering English, while the Hispanic students’ advance stalls out in the second and third grades as the demands of California’s English-proficiency test grow more difficult. Mandarin kindergartners establish oral skills in English in one year, the legislative analyst found, and by the beginning of second grade, they have begun developing a mastery of reading and writing, unlike Hispanics. The widening English-proficiency gap between Asian and Hispanic students may reflect parental willingness to expose children to English at home, but the gap occurs in math as well.

This summer in Southern California, I observed Hispanic students who had been taught in English throughout their school careers, yet who possessed very weak formal language ability. An in-class reading assignment at Locke High School in Watts asked students to answer the question: “Why is it important to use all your skills during your teen years?” A ninth-grader wrote in response: “To make it better.” Another question, “What sudden insight came to the engineer?” elicited the answer: “How to put the little mirrors.” While diagnosing the student-written sentence, “The pigs squealed loudly because the’re [sic] bored at the barn,” a high-school English teacher in Santa Ana asked his class: “Why does the dependent clause need to be in the past tense?” A student answered: “Because you’re talking about a lot of people.”

The Berkeley researchers speculate that the early decline in Hispanic students’ language and reasoning skills may reflect inadequate maternal stimulation in the home. And indeed, a Santa Ana elementary-school principal recounted to me her largely unsuccessful efforts to get parents to teach their children such basic kindergarten-survival tools as cutting with scissors and the words for colors. “Kids come in not knowing the alphabet in Spanish or the sounds of Spanish,” she said. “They use three-word sentences; they come in without oral-language ability.”

The Berkeley study will inevitably be used to buttress the Obama administration’s plans to pour billions of federal taxpayer dollars into early-education programs. As a matter of education policy, such efforts represent wishful thinking. Head Start has been repeatedly shown to have no lasting effect on students’ academic performance. Even the most successful and lavishly-funded of such early-intervention programs — the iconic Perry Preschool Project from the early 1960s in Ypsilanti, Mich. — explained only 3 percent of the earnings of its participants at age 40, and about 4 percent of their educational-attainment levels, wrote John J. Miller in NR in 2007. Replicating the Perry Project’s services on a national scale for Hispanic children would be extraordinarily expensive and produce only modest results. Many children who receive early intervention provide inferior intellectual stimulation for their own children, whether for innate cognitive or for cultural reasons.

But the more interesting implications of the study and others like it are for immigration policy. Our de facto immigration policy is currently weighted to a population that appears to require massive additional government education spending — even before formal schooling begins — to be made academically competitive. This choice would not seem to be economically rational, at least so long as we aspire to universal college-going. If the country remains committed to sending a far greater number of students to college, as even many conservatives continue to be, we better get ourselves a different mix of immigrants if we don’t want to bankrupt our education budgets. Alternatively, if the open-borders lobby prevails and Latin American migration continues to dominate our immigration flows, it’s time to acknowledge that many students never will be college material, nor do they need to be to lead productive, fulfilling lives.
