Knowing the stages of neurological development can make you a better parent
There are four main stages. Each has its own particular set of advancements and challenges.
Don't you wish you could predict your child's behavior with 100 percent accuracy? Any realistic parent knows it's an impossible daydream, but an appealing one nonetheless. Kids will always surprise you. There are so many factors that go into behavior, not to mention the fact that internal and external forces can sometimes make kids act out of character.
What you can do is come to understand the stages of their neurological development and what it means for their learning and behavior. Turns out, those parents who get a good grip on how we develop neurologically, are better able to guide their children toward positive outcomes. Here's a rundown of the stages of neurological development and what they mean for parenting.
The first is the sensorimotor stage. This takes places between birth and two-years. A child at this stage is getting used to experiencing the environment through their senses. Through trial and error and from experiences with objects and sensations, they begin to master the world around them. Around age one, the child learns object permanence, the concept that an object continues to exist, even when it's left the field of vision.
According to Sarah Lytle, PhD., from the Institute for Learning & Brain Sciences at the University of Washington in Seattle, what many parents don't fully realize is that babies are also developing socially and emotionally. As such, they usually look to their parent for support. If you've ever engaged with a baby you didn't know, you'll notice the child usually turns to their parent to gauge how to respond. This act is called social referencing or social cognition. Be sure to be supportive when the child does this. This allows for more confidence and independence.

A child's first word is uttered around six months of age. To help a baby develop language skills further, remember that they follow your gaze. Emphasize with your eyes by moving them slowly when introducing a new word. According to Dr. Lytle, it's okay to use a baby-talk tone. We're actually genetically programmed to talk that way. But make sure you use words correctly, in full, and in complete, grammatically correct sentences.
From age two to six or seven, a child enters the preoperational stage. Here, language skills ramp up. The child can start to think in terms of symbols, develop a numerical understanding, and begin to grasp the distinction between past and future. Children at this age do well with concrete situations. Abstract concepts, however, are difficult to grasp.
It's at age two that humans become amazed by the idea that others don't see the world quite like they do. As the parents of two-year olds are all too well aware of, this self-centered viewpoint makes it difficult for the child to share and care about others. Although a 2016 poll showed that most parents think two-year olds can control their emotions, psychologists say quite the contrary. Having a toy that they love on hand to distract them when they pull a temper tantrum is probably the best strategy.

To help build empathy, parents can work at developing a child's theory of mind. This is coming to understand the perspective of others. Note this doesn't develop until the child is three or four. One famous example is the “Sally-Anne test."
Here, a child is told that Sally has a basket and Anne a box. Sally puts an object in her basket, then goes for a walk. Anne takes the object and puts it in her box. The child is asked, “Once Sally returns, where will she look for the object?" If the child understands Sally's point of view, they will say, “In the basket." Another tactic it to read them stories where they have to put themselves in a character's shoes.
From age six or seven to 11 or 12, a child enters the concrete operations stage. Seven is supposed to be the age of reason. Here, he or she can grasp abstract concepts, understand sequences of events, and empathize with others whose experiences are different from their own. Children at this stage can learn abstract mathematical concepts, but they aren't good at breaking down complex problems which require systematic reasoning. Lytle suggests keeping in mind a child's emotional development at this stage. Parents often don't realize how affected their children are by marital spats or a parent suffering something like a bout of depression.
From age 12 throughout the teen years, the child enters the formal operations stage, where he or she develops greater capacities for hypothetical thinking, abstract reasoning, and deductive reasoning. Generally, people have a good grasp of these by age 15. Moral issues like social justice and abstract ideas, such as probabilities, can be understood. Although for parents, few stages can be quite as challenging.
Dealing with teens is challenging because of how their brains work. Getty Images.
Teens are often moody and hypersensitive. This is usually chalked up to hormones, but it's also because their midbrain is highly active in this stage. The brain develops from back to front.
The midbrain is responsible for memory, emotion, and sexuality. It may surprise you to know that the rational part of the brain, the prefrontal cortex, isn't fully developed until around age 25. This is responsible for things like decision-making, planning, impulse control, and risk avoidance.
Teens are more likely to evaluate situations with their amygdala or emotional center. This is why they tend to get overwhelmed by their emotions, but might have a hard time expressing them. It also explains their intermittent bend toward risky behavior. Make sure to talk to them often about drugs and alcohol, the risks of unprotected sex, and so on, and give them vocabulary they can use to avoid social pressures. When a teen does make a mistake, instead of scolding or lecturing, use it as a teachable moment. Walk them through it logically. Find out in their own words what they should have done differently. This can help them develop decision-making skills.
Also, work on giving them frontal lobe tasks or doing it with them. Give them opportunities to practice problem-solving, make judgment calls, or to plan things out. Do it together or debrief once they've completed the task. Sure, raising kids is far from easy, but knowing a little neuroscience can make a real difference.

How would the ability to genetically customize children change society? Sci-fi author Eugene Clark explores the future on our horizon in Volume I of the "Genetic Pressure" series.
- A new sci-fi book series called "Genetic Pressure" explores the scientific and moral implications of a world with a burgeoning designer baby industry.
- It's currently illegal to implant genetically edited human embryos in most nations, but designer babies may someday become widespread.
- While gene-editing technology could help humans eliminate genetic diseases, some in the scientific community fear it may also usher in a new era of eugenics.
Tribalism and discrimination<p>One question the "Genetic Pressure" series explores: What would tribalism and discrimination look like in a world with designer babies? As designer babies grow up, they could be noticeably different from other people, potentially being smarter, more attractive and healthier. This could breed resentment between the groups—as it does in the series.</p><p>"[Designer babies] slowly find that 'everyone else,' and even their own parents, becomes less and less tolerable," author Eugene Clark told Big Think. "Meanwhile, everyone else slowly feels threatened by the designer babies."</p><p>For example, one character in the series who was born a designer baby faces discrimination and harassment from "normal people"—they call her "soulless" and say she was "made in a factory," a "consumer product." </p><p>Would such divisions emerge in the real world? The answer may depend on who's able to afford designer baby services. If it's only the ultra-wealthy, then it's easy to imagine how being a designer baby could be seen by society as a kind of hyper-privilege, which designer babies would have to reckon with. </p><p>Even if people from all socioeconomic backgrounds can someday afford designer babies, people born designer babies may struggle with tough existential questions: Can they ever take full credit for things they achieve, or were they born with an unfair advantage? To what extent should they spend their lives helping the less fortunate? </p>
Sexuality dilemmas<p>Sexuality presents another set of thorny questions. If a designer baby industry someday allows people to optimize humans for attractiveness, designer babies could grow up to find themselves surrounded by ultra-attractive people. That may not sound like a big problem.</p><p>But consider that, if designer babies someday become the standard way to have children, there'd necessarily be a years-long gap in which only some people are having designer babies. Meanwhile, the rest of society would be having children the old-fashioned way. So, in terms of attractiveness, society could see increasingly apparent disparities in physical appearances between the two groups. "Normal people" could begin to seem increasingly ugly.</p><p>But ultra-attractive people who were born designer babies could face problems, too. One could be the loss of body image. </p><p>When designer babies grow up in the "Genetic Pressure" series, men look like all the other men, and women look like all the other women. This homogeneity of physical appearance occurs because parents of designer babies start following trends, all choosing similar traits for their children: tall, athletic build, olive skin, etc. </p><p>Sure, facial traits remain relatively unique, but everyone's more or less equally attractive. And this causes strange changes to sexual preferences.</p><p>"In a society of sexual equals, they start looking for other differentiators," he said, noting that violet-colored eyes become a rare trait that genetically engineered humans find especially attractive in the series.</p><p>But what about sexual relationships between genetically engineered humans and "normal" people? In the "Genetic Pressure" series, many "normal" people want to have kids with (or at least have sex with) genetically engineered humans. But a minority of engineered humans oppose breeding with "normal" people, and this leads to an ideology that considers engineered humans to be racially supreme. </p>
Regulating designer babies<p>On a policy level, there are many open questions about how governments might legislate a world with designer babies. But it's not totally new territory, considering the West's dark history of eugenics experiments.</p><p>In the 20th century, the U.S. conducted multiple eugenics programs, including immigration restrictions based on genetic inferiority and forced sterilizations. In 1927, for example, the Supreme Court ruled that forcibly sterilizing the mentally handicapped didn't violate the Constitution. Supreme Court Justice Oliver Wendall Holmes wrote, "… three generations of imbeciles are enough." </p><p>After the Holocaust, eugenics programs became increasingly taboo and regulated in the U.S. (though some states continued forced sterilizations <a href="https://www.uvm.edu/~lkaelber/eugenics/" target="_blank">into the 1970s</a>). In recent years, some policymakers and scientists have expressed concerns about how gene-editing technologies could reanimate the eugenics nightmares of the 20th century. </p><p>Currently, the U.S. doesn't explicitly ban human germline genetic editing on the federal level, but a combination of laws effectively render it <a href="https://academic.oup.com/jlb/advance-article/doi/10.1093/jlb/lsaa006/5841599#204481018" target="_blank" rel="noopener noreferrer">illegal to implant a genetically modified embryo</a>. Part of the reason is that scientists still aren't sure of the unintended consequences of new gene-editing technologies. </p><p>But there are also concerns that these technologies could usher in a new era of eugenics. After all, the function of a designer baby industry, like the one in the "Genetic Pressure" series, wouldn't necessarily be limited to eliminating genetic diseases; it could also work to increase the occurrence of "desirable" traits. </p><p>If the industry did that, it'd effectively signal that the <em>opposites of those traits are undesirable. </em>As the International Bioethics Committee <a href="https://academic.oup.com/jlb/advance-article/doi/10.1093/jlb/lsaa006/5841599#204481018" target="_blank" rel="noopener noreferrer">wrote</a>, this would "jeopardize the inherent and therefore equal dignity of all human beings and renew eugenics, disguised as the fulfillment of the wish for a better, improved life."</p><p><em>"Genetic Pressure Volume I: Baby Steps"</em><em> by Eugene Clark is <a href="http://bigth.ink/38VhJn3" target="_blank">available now.</a></em></p>
The father of all giant sea bugs was recently discovered off the coast of Java.
- A new species of isopod with a resemblance to a certain Sith lord was just discovered.
- It is the first known giant isopod from the Indian Ocean.
- The finding extends the list of giant isopods even further.
The ocean depths are home to many creatures that some consider to be unnatural.<img type="lazy-image" data-runner-src="https://assets.rebelmouse.io/eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpbWFnZSI6Imh0dHBzOi8vYXNzZXRzLnJibC5tcy8yMzU2NzY4My9vcmlnaW4ucG5nIiwiZXhwaXJlc19hdCI6MTYxNTUwMzg0NX0.BTK3zVeXxoduyvXfsvp4QH40_9POsrgca_W5CQpjVtw/img.png?width=980" id="b6fb0" class="rm-shortcode" data-rm-shortcode-id="2739ec50d9f9a3bd0058f937b6d447ac" data-rm-shortcode-name="rebelmouse-image" data-width="1512" data-height="2224" />

A new study explains how a chaotic region just outside a black hole's event horizon might provide a virtually endless supply of energy.
- In 1969, the physicist Roger Penrose first proposed a way in which it might be possible to extract energy from a black hole.
- A new study builds upon similar ideas to describe how chaotic magnetic activity in the ergosphere of a black hole may produce vast amounts of energy, which could potentially be harvested.
- The findings suggest that, in the very distant future, it may be possible for a civilization to survive by harnessing the energy of a black hole rather than a star.
The ergosphere<p>The ergosphere is a region just outside a black hole's event horizon, the boundary of a black hole beyond which nothing, not even light, can escape. But light and matter just outside the event horizon, in the ergosphere, would also be affected by the immense gravity of the black hole. Objects in this zone would spin in the same direction as the black hole at incredibly fast speeds, similar to objects floating around the center of a whirlpool.</p><p>The Penrose process states, in simple terms, that an object could enter the ergosphere and break into two pieces. One piece would head toward the event horizon, swallowed by the black hole. But if the other piece managed to escape the ergosphere, it could emerge with more energy than it entered with.</p><p>The movie "Interstellar" provides an example of the Penrose process. Facing a fuel shortage on a deep-space mission, the crew makes a last-ditch effort to return home by entering the ergosphere of a blackhole, ditching part of their spacecraft, and "slingshotting" away from the black hole with vast amounts of energy.</p><p>In a recent study published in the American Physical Society's <a href="https://journals.aps.org/prd/abstract/10.1103/PhysRevD.103.023014" target="_blank" style="">Physical Review D</a><em>, </em>physicists Luca Comisso and Felipe A. Asenjo used similar ideas to describe another way energy could be extracted from a black hole. The idea centers on the magnetic fields of black holes.</p><p style="margin-left: 20px;">"Black holes are commonly surrounded by a hot 'soup' of plasma particles that carry a magnetic field," Comisso, a research scientist at Columbia University and lead study author, told <a href="https://news.columbia.edu/energy-particles-magnetic-fields-black-holes" target="_blank" rel="noopener noreferrer">Columbia News</a>.</p>
Event Horizon Telescope Collaboration<p>While there might not be immediate applications for the theory, it could help scientists better understand and observe black holes. On an abstract level, the findings may expand the limits of what scientists imagine is possible in deep space.</p><p style="margin-left: 20px;">"Thousands or millions of years from now, humanity might be able to survive around a black hole without harnessing energy from stars," Comisso said. "It is essentially a technological problem. If we look at the physics, there is nothing that prevents it."</p>
A popular and longstanding wave of thought in psychology and psychotherapy is that diagnosis is not relevant for practitioners in those fields.
