Psychologist Kenneth Kaye finds that, while parent-child interaction may be crucial for emotional development, most of it is irreverent to congnitive developement. "A child comes equipped with an innate timetable for mental growth, and all the jiggles and coos have little effect on the rate of cognitive growth," says Kaye.
This seems to explain the inability of developmental researchers to find any significant link between how much time and effort parents put into talking to their child, and the rate of the child's cognitive growth. It's a bit like vitamin C, Kaye says. We all need some, but whether you get 100 milligrams or 1000 will not improv your health, because he he crucial range for the vitamin is between zero and 60 milligrams. The deficiency shows up only in the very lowest range. The same is true of parental attempts to hasten cognitive development.
