Study: fathers are important for the development of children’s brains

The study was reported in the Wall Street Journal.

Excerpt:

Dr. Braun’s group found that at 21 days, the fatherless animals had less dense dendritic spines compared to animals raised by both parents, though they “caught up” by day 90. However, the length of some types of dendrites was significantly shorter in some parts of the brain, even in adulthood, in fatherless animals.

“It just shows that parents are leaving footprints on the brain of their kids,” says Dr. Braun, 54 years old.

The neuronal differences were observed in a part of the brain called the amygdala, which is related to emotional responses and fear, and the orbitofrontal cortex, or OFC, the brain’s decision-making center.

[…]The balance between these two brain parts is critical to normal emotional and cognitive functioning, according to Dr. Braun. If the OFC isn’t active, the amygdala “goes crazy, like a horse without a rider,” she says. In the case of the fatherless pups, there were fewer dendritic spines in the OFC, while the dendrite trees in the amygdala grew more and longer branches.

A preliminary analysis of the degus’ behavior showed that fatherless animals seemed to have a lack of impulse control, Dr. Braun says. And, when they played with siblings, they engaged in more play-fighting or aggressive behavior.

In a separate study in Dr. Braun’s lab conducted by post-doctoral researcher Joerg Bock, degu pups were removed from their caregivers for one hour a day. Just this small amount of stress leads the pups to exhibit more hyperactive behaviors and less focused attention, compared to those who aren’t separated, Dr. Braun says. They also exhibit changes in their brain.

The basic wiring between the brain regions in the degus is the same as in humans, and the nerve cells are identical in their function. “So on that level we can assume that what happens in the animal’s brain when it’s raised in an impoverished environment … should be very similar to what happens in our children’s brain,” Dr. Braun says.

I think this is important because we hear so much today that marriage can be redefined, that having one of each parent doesn’t matter, that live-in boyfriends and stepfathers have the same motivation to care for a woman’s children as the biological father does. We don’t want to make judgments, even if setting boundaries is better for children. A child’s well-being is enormously affected by the woman’s choice of biological father.  You can’t have it both ways – either we are going to judge women who choose men who don’t have the desire to commit to marriage, and do the father role, OR we are going to take things away from children by encouraging women to choose men based on “feelings” instead of abilities. Lowering moral standards and removing moral obligations hurts children. It sounds so nice when we tell women, “you can do whatever you feel like, and just forget about responsibilities, expectations and obligations”, but letting women be guided by their feelings harms children. My stock broker makes me feel uncomfortable because he knows more than I do, and does not respect my opinion. But I pay him to make investment decisions for me. I mustn’t let my pride get in the way of letting him do his job – a job he is more qualified than I am to do. Let him do his job.

Here’s a related question: Are biological fathers or unrelated men more dangerous for children?

This article from the Weekly Standard answers the question.

Excerpt:

A March 1996 study by the Bureau of Justice Statistics contains some interesting findings that indicate just how widespread the problem may be. In a nationally representative survey of state prisoners jailed for assaults against or murders of children, fully one-half of respondents reported the victim was a friend, acquaintance, or relative other than offspring. (All but 3 percent of those who committed violent crimes against children were men.) A close relationship between victim and victimizer is also suggested by the fact that three-quarters of all the crimes occurred in either the perpetrator’s home or the victim’s.

A 1994 paper published in the Journal of Comparative Family Studies looked at 32,000 documented cases of child abuse. Of the victims, only 28 percent lived with both biological parents (far fewer than the 68 percent of all children who live with both parents); 44 percent lived with their mother only (as do 25 percent of all children); and 18 percent lived with their mother and an unrelated adult (double the 9 percent of all children who live with their mother and an unrelated adult).

These findings mirror a 1993 British study by the Family Education Trust, which meticulously explored the relationship between family structure and child abuse. Using data on documented cases of abuse in Britain between 1982 and 1988, the report found a high correlation between child abuse and the marital status of the parents.

Specifically, the British study found that the incidence of abuse was an astounding 33 times higher in homes where the mother was cohabiting with an unrelated boyfriend than in stable nuclear families. Even when the boyfriend was the children’s biological father, the chances of abuse were twice as high.

These findings are consonant with those published a year earlier by Leslie Margolin of the University of Iowa in the journal Child Abuse and Neglect. Prof. Margolin found that boyfriends were 27 times more likely than natural parents to abuse a child. The next-riskiest group, siblings, were only twice as likely as parents to abuse a child.

More recently, a report by Dr. Michael Stiffman presented at the latest meeting of the American Academy of Pediatrics, in October, studied the 175 Missouri children under the age of 5 who were murdered between 1992 and 1994. It found that the risk of a child’s dying at the hands of an adult living in the child’s own household was eight times higher if the adult was biologically unrelated.

The Heritage Foundation’s Patrick Fagan discovered that the number of child-abuse cases appeared to rise in the 1980s along with the general societal acceptance of cohabitation before, or instead of, marriage. That runs counter to the radical-feminist view, which holds that marriage is an oppressive male institution of which violence is an integral feature. If that were true, then child abuse and domestic violence should have decreased along with the rise in cohabitation.

Heritage also found that in the case of very poor children (those in households earning less than $ 15,000 per year), 75 percent lived in a household where the biological father was absent. And 50 percent of adults with less than a high-school education lived in cohabitation arrangements. “This mix — poverty, lack of education, children, and cohabitation — is an incubator for violence,” Fagan says.

Why, then, do we ignore the problem? Fagan has a theory: “It is extremely politically incorrect to suggest that living together might not be the best living arrangement.”

The moral of the story is that it is a lot safer for children if we promote marriage as a way of attaching mothers and fathers to their children. Fathers who have a biological connection to children are a lot less likely to harm them. We should probably be teaching women to choose men who have a certain tenderness towards people they mentor or nurture, as well. These things are not free, you have to persuade women to value the male tendency to want to lead / guide / mentor. A lot of social problems like child poverty, promiscuity and violence cannot be solved by replacing a father with a check from the government. We need to support fathers by empowering them in their traditional roles. Let the men lead. Swallow your feminist instincts, and prefer men who take seriously their role of leading others upward.

New study: children’s brains function better when they can see their mothers

The new study published in Psychological Science was reported in Pacific Standard.

Excerpt:

For little kids, seeing mom or dad nearby is a calming influence, maybe the difference between between perfect calm and a full-bore freakout. It’s as if having a trusted caregiver nearby transforms children from scared toddlers into confident adolescents. And in a way, a new report suggests, that’s what having mom around does to a kid’s brain.

When they’re first born and for years after, infants and young children can’t do a whole lot by themselves. They can’t eat on their own, they aren’t very good at managing their emotions, and it takes a while for them to learn how to dress themselves. Most children figure it out eventually, but in the meantime they need their parents to do a lot of that stuff for them. All the while, their brains are changing, too. Well into adolescence, kids’ brains undergoanatomical and physiological changes that affect the way we think and act.

[…]Young children’s brains responded differently based on whether they were looking at their mothers or strangers. In particular, their brains showed signs of positive amygdala-PFC connections when viewing pictures of strangers, but negative connections when viewing pictures of their mothers, suggesting more mature and stable brain function—and likely more mature and stable behavior, at least when moms were around. In contrast, tweens and teens had negative connections whether they were looking at their mothers or strangers. In other words, looking at pictures of their mothers made young children’s brains look a little more like those of adolescents.

The companion behavioral experiment backed up that thinking—young children made around 20 percent fewer errors when their mothers were present than when they weren’t, while there was no difference for adolescents. That combined with the fMRI results to suggest that mothers—and likely other caregivers—can provide an external source of mental regulation that young children won’t develop until later in life, the authors write in Psychological Science.

In view of the recent triumphs for gay marriage advocates, I think it’s worth remembering that gay marriage, like single motherhood, is not the best we can do for children. I think it’s a bad enough situation when the husband dies and leaves his children to be raised by the mother. That’s hard, but it’s not immoral. On the other hand, I think that deliberately choosing to deprive a child of his or her mother or father IS immoral. It’s child abuse, in my opinion. And that goes for gay marriage as well as “single motherhood by choice”. I also oppose frivolous divorce (“frivorce”), which is very popular in a nation that views structured courtship as “boring” and no-fault divorce as a woman’s right.

Previously, I blogged about another study that showed the importance of moms for young children.

Excerpt:

Both of these images are brain scans of a two three-year-old children, but the brain on the left is considerably larger, has fewer spots and less dark areas, compared to the one on the right.

According to neurologists this sizeable difference has one primary cause – the way each child was treated by their mothers.

The child with the larger and more fully developed brain was looked after by its mother – she was constantly responsive to her baby, reported The Sunday Telegraph.

But the child with the shrunken brain was the victim of severe neglect and abuse.

According to research reported by the newspaper, the brain on the right worryingly lacks some of the most fundamental areas present in the image on the left.

The consequences of these deficits are pronounced – the child on the left with the larger brain will be more intelligent and more likely to develop the social ability to empathise with others.

But in contrast, the child with the shrunken brain will be more likely to become addicted to drugs and involved in violent crimes, much more likely to be unemployed and to be dependent on state benefits.

The child is also more likely to develop mental and other serious health problems.

Professor Allan Schore, of UCLA, told The Sunday Telegraph that if a baby is not treated properly in the first two years of life, it can have a fundamental impact on development.

He pointed out that the genes for several aspects of brain function, including intelligence, cannot function.

[…]The study correlates with research released earlier this year that found that children who are given love and affection from their mothers early in life are smarter with a better ability to learn.

The study by child psychiatrists and neuroscientists at Washington University School of Medicine in St. Louis, found school-aged children whose mothers nurtured them early in life have brains with a larger hippocampus, a key structure important to learning, memory and response to stress.

The research was the first to show that changes in this critical region of children’s brain anatomy are linked to a mother’s nurturing, Neurosciencenews.com reports.

The research is published online in the Proceedings of the National Academy of Sciences Early Edition.

Lead author Joan L. Luby, MD, professor of child psychiatry, said the study reinforces how important nurturing parents are to a child’s development.

I have a very good feminist non-Christian friend who sometimes comments here. I once asked her about marriage and she said that her skills would be wasting on raising children. I explained to her my view that a mother needs to stay at home with the children, and that is more important work. I expect my future wife to read all kinds of books on child care and to give the child attention, nutrition, exercise and play so that the child will grow up to be an effective Christian. Maybe I need to be clear. I am not going to spend hundreds of thousands per child with just any woman. I need a woman who can produce influential and effective Christians who will engage in the public square. And we do not entrust that job to just anyone. We want educated, professional women who are willing to be stay-at-home moms when it’s necessary to do that – for the sake of the children.

I expect the woman I marry (if I marry) to have a college degree, and preferably a graduate degree, and at least a couple of years of employment. Then she has to stay home and invest in those children through the first five years, at least. After that she can stay home or work as much as she thinks is beneficial to the family goals of impacting the university, the church and the public square – as well as continuing to raise those children. It’s not a waste of her talent to make the next William Lane Craig, or the next Marsha Blackburn, or the next Doug Axe, or the next Edith Hollan Jones.

Physicist Victor Stenger debates William Lane Craig: Does God Exist?

This debate took place on March 1, 2010 at Oregon State University.

In this debate, Victor Stenger does affirm his belief that the universe could be eternal in his second rebuttal (1:02:30), thus denying the standard Big Bang cosmology. He also denies the law of conservation of energy and asserts that something can come from nothing in his concluding speech (1:33:50). He also caused the audience to start laughing when he said that Jesus was not moral and supported slavery. There is almost no snark in this summary. Instead, I quoted Dr. Stenger verbatim in many places. I still think that it is very entertaining even without the snarky paraphrasing.

The debate includes 30 minutes of Q&A with the students.

Here is the MP3 file for the audio.

Here’s the video of the debate:

Dr. Craig’s opening speech:

  • The ontological argument
  • The contingency argument
  • The cosmological argument
  • The moral argument
  • The resurrection of Jesus (3-fact version)
  • Religious experience

Dr. Stenger’s opening speech:

  • There is no scientific evidence for God’s existence in the textbooks
  • There is no scientific evidence for God acting in the universe
  • God doesn’t talk to people and tell them things they couldn’t possibly know
  • The Bible says that the Earth is flat, etc.
  • There is no scientific evidence that God answers prayers
  • God doesn’t exist because people who believe in him are ignorant
  • Human life is not optimally designed and appears to be the result of a blind, ad hoc evolutionary process
  • The beginning of the universe is not ordered (low entropy) but random and chaotic
  • It’s theoretically possible that quantum tunneling explains the origin of the universe
  • The laws of physics are not objectively real, they are “our inventions”
  • Regarding the beginning of the universe, the explanation is that something came from nothing*
  • Nothing* isn’t really nothing, it is “the total chaos that we project existed just before the big bang”
  • If something has no structure, then “it is as much nothing as nothing can be”
  • Consciousness is explainable solely on the basis of material processes
  • There are well-informed, rational non-believers in the world and God would not allow that

Dr. Craig’s first rebuttal:

Stenger’s argument that there is no objective evidence for God’s existence:

  • First, it is not required that God rely only on objective evidence in order to draw people to himself (Alvin Plantinga)
  • Second, God is not required to provide evidence to everyone, only to the people who he knows would respond to him
  • Third, Craig gave lots of objective evidence, from science, history and philosophy
  • Stenger asks for certain evidence (answered prayers, prophecy, etc.), but Craig presented the evidence we have

Stenger’s argument that the balance of energy is zero so “nothing” exists:

  • if you have the same amount of assets and liabilities, it doesn’t mean that nothing exists – your assets and liabilities exist
  • Christopher Isham says that there needs to be a cause to create the positive and negative energy even if they balance
  • the quantum gravity model contradicts observations
  • the vacuum is not the same as nothing, it contains energy and matter
  • the BVG theorem proves that any universe that is expanding must have a beginning

Stenger’s argument that mental operations can be reduced to physical operations:

  • mental properties are not reducible to physical properties
  • epiphenomenalism: is incompatible with self-identity over time
  • epiphenomenalism: is incompatible with thoughts about other things
  • epiphenomenalism: is incompatible with free will
  • substance dualism (mind/body dualism) is a better explanation for our mental experience
  • God is a soul without a body
Dr. Stenger’s first rebuttal:

Craig’s cosmological argument:

  • Craig’s premise is “everything has a cause”, but quantum mechanics has causeless events
  • There are speculative theories about how something could have come into being uncaused out of nothing
  • “I don’t know of a single working cosmologist today who believes there was a singularity prior to the Big Bang”
  • “If there wasn’t a singularity then there’s no basis for arguing that time began at that point”
  • “There’s no reason from cosmology that we know of that the universe can’t be eternal”
  • “When I talk about an eternal universe, I mean a universe that has no beginning or end”
  • The Hartle-Hawking model doesn’t have a beginning
  • “There was no violation of energy conservation by having a universe coming from nothing”
  • “The universe could have come from a previous universe for example or even just from a region of chaos”
  • The paper by Vilenkin is counteracted by other papers (he doesn’t specify which ones)

Craig’s moral argument:

  • Dr. Craig is arguing from ignorance
  • But morality can be decided by humanity just like governments pass laws, and that’s objective
  • Dr. Craig has too little respect for the human intellect
  • I don’t need to tell me that slavery is wrong
  • The Bible supports slavery
  • Atheists can behave as good as theists
  • Morality just evolved naturally as an aid to survival

Craig’s resurrection argument:

  • No Roman historians wrote about the execution of Jesus but none of them did
  • The empty tomb is doubtful because it is only mentioned in the gospels, not by Paul
  • John Dominic Crossan says there was no empty tomb
  • Christianity only survived because the Roman empire thought that they were useful

Dr. Craig’s second rebuttal:

Craig’s cosmological argument:

  • There is no reason to prefer an indeterministic interpretation of quantum mechanics
  • Dr. Stenger himself wrote that deterministic interpretations of quantum mechanics are possible
  • The vacuum in quantum mechanics is not nothing
  • The quantum vacuum he proposes cannot be eternal
  • The cosmological argument does not require a singularity
  • The Hartle-Hawking model is from 1983
  • Hawking says that there is a beginning of space and time after that model
  • The Hartle-Hawking model does still have a beginning of time – the model is not eternal
  • The BVG theorem that requires a beginning for expanding universes is widely accepted among cosmologists

Craig’s moral argument:

  • Stenger redefined objective to mean that most people agree with it – but that’s not what objective means
  • Objective means right and wrong whether anyone accepts it or not
  • Richard Dawkins himself says that on atheism there is “no evil and no good” – why is he wrong?
  • Even Dr. Stenger says that morality is the same as passing laws – it’s arbitrary and varies by time and place
  • But on his view, right and wrong are the same as deciding which side of the road to drive on
  • But somethings really are right and some things are really wrong

Craig’s resurrection argument:

  • Josephus is a Roman historian and he wrote about Jesus, for example
  • There were four biographies of Jesus are the best sources for his life
  • The scholars that Stenger mentioned are on the radical fringe

Dr. Stenger’s second rebuttal:

Knowledge and the burden of proof:

  • Dr. Craig has to bear the burden of proof, not me – because his claim is more “extravagant”
  • “I don’t have to prove that a God was not necessary to create the universe”
  • “I don’t have to prove that a God did not design the universe and life”
  • “I don’t have to prove that the universe did not have a beginning”
  • “I don’t have to prove that God did not provide us with our moral sense”
  • There are a lot of books written about how morality evolved naturally
  • “I don’t have to prove that the events surrounding the supposed resurrection of Jesus did not take place”
  • Bart Ehrman says that the gospels are generally unreliable (Note: Ehrman accepts all 3 of Craig’s minimal facts)
  • Just because people are willing to die for a cause, does not make their leader God, e.g. – the Emperor of Japan

Aesthetic concerns about the universe:

  • I don’t like dark matter and I wouldn’t have made the universe with dark matter
  • I don’t like the doctrine of penal substitution
  • I don’t like the doctrine of original sin
  • I don’t like the heat death of the universe

Dr. Craig’s conclusion:

The case for atheism:

  • Dr. Stenger had two arguments and he has to support his premises
  • Dr. Craig addressed his two arguments and each premise and Dr. Stenger never came back on it

The contingency argument:

  • Dr. Stenger has dropped the refutation of this argument

The cosmological argument:

  • The theoretical vacuum he proposes cannot be eternal

The moral argument:

  • He asserts that things are wrong, but there is no grounding for that to be objective on atheism

The resurrection of Jesus:

  • There are surveys of scholars on the empty tomb and 75% of them agree with it
  • Bart Ehrman agrees with all 3 of the minimal facts that Dr. Craig presented
  • Ehrman’s objection to the resurrection is not historical: he’s an atheist – he thinks miracles are impossible

Religious experience:

  • No response from Dr. Stenger

Dr. Stenger’s conclusion

The cosmological argument:

  • “I argued that we have very good physical reasons to understand how something can come from nothing”
  • “There is a natural tendency in the universe… to go from.. simpler thing to the more complicated thing”
  • The transition from a vapor to a liquid to ice shows how something could come from nothing
  • “It cannot be proven that the universe had a beginning”

The moral argument:

  • Objective morality, which is independent of what people think, could be developed based on what people think
  • “Jesus himself was not a tremendously moral person… he had no particular regard for the poor… he certainly supported slavery… he was for the subjugation of women” (audience laughter)

The resurrection argument:

  • Bart Ehrman says that the majority of the gospels are unreliable

Religious experience:

  • I don’t see any evidence that there is anything more to religious experience than just stuff in their heads

God’s purpose of the world should be to make people feel happy:

  • God could have made people feel happier
  • God could have made people not die
  • God could could have made the universe smaller: it’s too big
  • God could have made it possible for humans to live anywhere “even in space”
