Of its several advantages, "birtn stress" has been found to be especially beneficial for a newborn's breathing. Compared with babies born by C'Section, vaginally delivered babies are quicker to take their first breaths; their blood oxygen levels rise more rapidly after birth; and they are less likely to suffer any of…
As we learn more about maternal hormones and their influence on the developing brain, scientists are beginning to propose actual biological mechanisms for the kind of folk prophecies that have been around for ages. One recent study, for instance, suggests that a child's shyness is determined, in part, by maternal…
Most women also realize that smoking is bad during pregnancy. Unfortunately, it can be a very hard habit to give up, even for the best-intentioned parent. Smoking is not as detrimental to fetal brain development as heavy alcohol drinking, but it acts on many other organ systems. like the heart and lungs, that…
The similarity between different vertebrate embryos is indeed remarkable. Since the early 1800s, embryologists have been struck by the parallel between early development in various animal species and their evolutionary relationship, a resemblance conveniently abbreviated by the saying "ontogeny recapitulates…
What are the babies' representations and rules like? First, the babies' representations are rich and complex. As we've seen, they include ideas about how their face resembles the faces of others, how objects move, and how the sounds of a language are divided. The young babies' world is not simple. Babies translate the…
The theories that did dominate psychology, especially in America, were Freudianism and the behaviorism of psychologists like B. F. Skinner. Both theories had lots of things to say about young children. But like Aristotle with the teeth, neither Freud nor Skinner took the step of doing systematic experiments with…
Once you know about sitters and rovers, you see them everywhere, especially among young children. Drop in on your local Mommy and Me music class: there are the sitters, intently watching the action from their mothers’ laps, while the rovers march around the room banging their drums and shaking their maracas. Relaxed…
Before 1980, this would have seemed a strange question. Social anxiety disorder did not officially exist until it appeared in that year’s Diagnostic and Statistical Manual, the DSM-III, the psychiatrist’s bible of mental disorders, under the name “social phobia.” It was not widely known until the 1990s, when…
Let me look at the envelope from a very basic point of view, that of the neurophysiology of raw perception itself. Forgive me if it’s a bit oversimple. Take me-on the back of your retina I’m upside down, focused at the center but fuzzy at the edges, two-dimensional, a barrage of photons releasing rhodopsin and…
The custom of being satisfied with born prejudice has prevailed, and by following this custom, mankind agrees in all things with persons interested in supporting stubbornly the opinions thus received, and who would speak otherwise did they not fear to destroy themselves.
By the standard of other substances, the properties of ice are bizarre, yet ice is so perfectly suited to our purpose that if it didn't exist we should have to invent it. With few exceptions, the solid phase of matter is more dense than the liquid phase; water. alone among common substances, violates the rule. As…
A stress-related decline in the sex ratio is no anomaly, but a biological mechanism that evolved to keep the species going, according to Ralph Catalano, professor of public health at the University of California, Berkeley. “From an evolutionary perspective, in stressful eras it’s a smarter bet to have a female child…
The finest emotion of which we are capable is the mystic emotion. Herein lies the germ of all art and all true science. Anyone to whom this feeling is alien, who is no longer capable of wonderment and lives in a state of fear is a dead man. To know that what is impenatrable for us really exists and manifests itself as…
They say it's narcissistic to push your kids to follow in your footsteps, but when they say that, they must be talking about other people. After all, my footsteps, often covered with disposable clean-room booties, lead to science, which is a responsibly nerdy career choice. Or is it? Credit: Hal Mayforth Nerdy, yes…
It would be desirable for the government to authorize people to go into the factories and shops, to see the craftsmen at their work, to question them, to draw the tools, the machines, and even the premises. There are special circumstances when craftsmen are so secretive about their techniques that the shortest way of…
I have I have said I have said that it could only belong to a philosophical age to attempt an encyclopidie; and I have said this because such a work constantly demands more intellectual daring than is commonly found in ages of pusillanimous taste. All things must be examined, debated, investigated without exception…
I can remember the night that I suddenly realized what it was like to be crazy, or nights when my feelings and perceptions were of a religious nature. I had a very accurate sense that these feelings and perceptions, written down casually, would not stand the usual critical scrutiny that is my stock in trade as a…
There is a very nice self-titering aspect to cannabis. Each puff is a very small dose; the time lag between inhaling a puff and sensing its effect is small; and there is no desire for more after the high is there. I think the ratio, R, of the time to sense the dose taken to the time required to take an excessive dose…
You can use anchoring on yourself to quickly put yourself in a good or enthusiastic mood! Close your eyes and imagine a time when you were excited and motivated. Create a vivid mental picture. Now, when you are immersed in that motivated feeling, lightly scratch the pad of your index finger with your thumbnail. You're…
Overcoming fear requires you to train yourself to think every time you feel fear, rather than just reacting instinctively. The thought process I go through goes like this: I'm scared. Is it physical danger? No. Well, when I make a decision based on fear, it's often a bad one, so I'm going to put the fear aside and ask…
