With factors ranging as broadly as poverty, consumption of Nutrasweet, and watching television, it is difficult to know how to enact policy towards improving education based on Healy's recommendations. But it makes for an interesting read. At times Healy is very biased: anti-Sesame Street and subtly racist (referring to "non-native" speakers as "inferior. {Those who don't speak Algonquin?} But other times, I appreciate the sophistication of her thought such as discussing nature/nurture and left hemisphere, right hemisphere as a blend, not a bifurcation.
There were three chapters that particularly caught my attention. The first was "Sagging syntax, sloppy semantics, and fuzzy thinking." It included components of the first research paper I ever wrote in college such as language-delayed acquisition and brain structures in an attempt to capture what influence language has on thought. Healy argues that syntax is the most fundamental aspect of speech to altering thought, but it is also the most vulnerable to deprivation.
"TV, video games, and the growing brain" is woefully outdated. The book was written in 1990 and Healy claims that not enough research has been done on media's effects of the brain that we can conclude much of anything. She makes lots of guesses though. Some of her critiques included that TV is over-stimulating with its many zooms and cuts making it hard for children to pay attention to more normal stimuli, that it trains children to be passive, that it makes the brain produce alpha waves instead of the more alert beta, and that there is no evidence to support transfer of skills when playing computer games. Reading this chapter definitely made me want to read more current research on this topic.
Healy is strongly opposed to Sesame Street. Her main critique is that the skits are too short and rapid-paced to even make sense to pre-schoolers, let alone teach them anything. Also, the decontextualized numbers, letters, and words do a disservice towards teaching syntax, which as mentioned before, highly structures thought. I think adults might be able to mitigate some of these negative effects by watching Sesame Street with our children, and pausing between skits to talk to our children about what we've seen.
