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.

4. Marriage is a virtually universal human institution.

ECONOMICS

5. Divorce and unmarried childbearing increase poverty for both children and mothers
6. Married couples seem to build more wealth on average than singles or cohabiting couples
7. Married men earn more money than do single men with similar education and job histories
8. Parental divorce (or failure to marry) appears to increase children’s risk of school failure
9. Parental divorce reduces the likelihood that children will graduate from college and achieve high-status jobs

PHYSICAL HEALTH AND LONGEVITY

10.Children who live with their own two married parents enjoy better physical health, on average, than do children in other family forms
11.Parental marriage is associated with a sharply lower risk of infant mortality
12.Marriage is associated with reduced rates of alcohol and substance abuse for both adults and teens
13.Married people, especially married men, have longer life expectancies than do otherwise similar singles

MENTAL HEALTH AND EMOTIONAL WELL-BEING

15.Children whose parents divorce have higher rates of psychological distress and mental illness
16.Divorce appears significantly to increase the risk of suicide
17.Married mothers have lower rates of depression than do single or cohabiting mothers

CRIME AND DOMESTIC VIOLENCE

18.Boys raised in single-parent families are more likely to engage in delinquent and criminal behaviour
19.Marriage appear to reduce the risk that adults will be either perpetrators or victims of crime
20.Married women appear to have a lower risk of experiencing domestic violence than do cohabiting or dating women
21.A child who is not living with his or her own two married parents is at greater risk of child abuse
