Talk to Your Babies
The more parents talk to their children, even in the earliest moments of life, the better their kids linguistic abilities become and the faster that improvement is achieved. The gold standard is 2,100 words per hour. The variety of the words spoken (nouns, verbs, and adjectives used, along with the length and complexity of phrases and sentences) is nearly as important as the number of words spoken. So is the amount of positive feedback. You can reinforce language skills through interaction: l...
1 2,100 words per hour in a variety of words. Babies are listening.
The Theory of Neuromuscular Maturation
Believe it or not, it is only relatively recently that scientists have begun to appreciate the importance of babies' earliest motor activity. In the first part of this century, most researchers championed the view that motor development is largely innate, or "hard-wired." Struck by the remarkable consistency of skill acquisition, they argued that motor development depends solely on a fixed process o{ neuromuscular maturation (as their theory came to be called). with little role for practice o...
notesExercising babies in neuromotor skills appears to have no effect on the development of those skills. The infants body will acquire those skills when they are sufficiently developed for them.
Hyperacuity and Obligatory Looking
Beginning about four months of age, the perception of detail takes another leap forward with the emergence of hyperacuity: the ability to discriminate features that are up to ten times finer than the size of the photoreceptors should theoretically permit. It is this ultrafine discrimination that allows us, for instance, to see a very slight glitch in an otherwise straight line. even though the size of the glitch is below our eyes' limit of resolution. It is not yet known how our brains perfor... notesTwo visual phenomena in the developing infant. One is the ability to make out visual details for which the eye does not appear physically capable of registering and the other is a conflict between the visual cortex and the brain stem that gets the baby stuck staring at something.
Varying Breast Milk Flavoring
One reason why researchers have had such a hard time replicating the composition of breast milk is that it isn't a fixed commodity. No two women's milk is identical, nor is the composition of any one mother's milk constant at all times; it varies with the amount of time that has elapsed postpartum, gradually changing in composition to match the baby's changing nutritional needs. It also varies with time of day, with the thinnest milk (the lowest tat content) being produced early in the day an... notesBy eating a variety of differently flavored foods, like garlic, mint, vanilla, etc, the infant is exposed to a variety of flavors of breast milk,
The Importance of Nutrition in the Developing Mind
In the case of a mother's more general nutritional status—her tota caloric intake—the brain is actually less sensitive during the first three to four months of gestation. In spite of its massive developmental changes, the fetus grows surprisingly little in size during this period, so its growth is not very dependent on the mother's diet. (This is probably no accident, since women are often unable to consume many calories because of first-trimester nausea.) Beginning around midway through ...There is a crucial period in fetal development where nutrition is of the utmost importance to the growing brain. If these nutritional needs are not met, then the baby's intelligence may suffer.
Babies Categorize Sounds Before Words
As they hear us talk, babies are busily grouping the sounds they hear into the right categories, the categories their particular language uses. By one year of age, babies' speech categories begin to resemble those of the adults in their culture. Pat conducted some even more complicated experiments with Swedish babies using simple vowels to see how early they start organizing the sounds of their language in an adult-like way. She showed that at six months the process has already begun. The six...Babies learn the sounds of their language, which gives them the ability to distinguish and categorize words later on.
Scientists Emulate Babies
We think there are very strong similarities between some particular types of early learning—learning about objects and about the mind, in particular—and scientific theory change. In fact, we think they are not just similar but identical. We don't just think that the baby computers have the same general structure as the adult-scientist computers, in the way that perceptual learning and artistic learning and political learning may all have the same general structure. We think that children ...We have even institutionalized an environment of infancy for scientists in academia, where they are allowed to explore freely in general research, understanding that the discoveries made there may hold great benefits for the human race. This meme also suggests that free inquiry is an important aspect of raising children and maintaining an environment of free inquiry for parents is important as well.
Looking at babies attentively makes us treat them differe...
Until very recently doctors didn't use analgesia when they operated on small babies, because they thought their minds were too primitive to really feel pain or to remember it if they did. This is a dramatic example, but it often seems as if we discount children's pain compared with adult pain. Child abuse isn't evil because it may produce neurotic adults but because it abuses children. Divorce doesn't have a cost because it may produce adults who have difficulty with relationships but because...Seeing babies as young adults makes us treat them humanely; whereas, in the past, babies were denied analgesia because it was thought that their primitive minds did not sense pain the way an adult's mind did.
Babies are Scientists
Babies start out believing that there are profound similarities between their own mind and the minds of others. That belief gives them a jump start in solving the Other Minds problem. But during the first three years they also observe the differences in what people do and say. Those differences stem from the fact that all minds aren't actually entirely alike. Babies and young children watch and listen with careful focused interest as their mother refuses to let them touch the lamp cord or as ... notesTheir drive to play is a drive to explore, they are equipped with the cognitive and physical tools to explore their world and feed their curiosity about it.
Nature VS Nurture in Child Development
When a three-month-old, a one-year-old, and a four-year-old look at the same event, they seem to have very different thoughts about it. They seem to transform the light waves and sound waves into different representations, and they use different rules to manipulate those representations. Children don't have just a single, fixed program that gets from input to output. Instead, they seem to switch spontaneously from using one program to using another, more powerful program. That makes babies an... notesAre babies programmed to go through their cognitive developments or are they the natural result of their reaching a certain critical mass of understanding?
