New study examines if the gender of parents matter

The presumption that children need both a mother and a father is widespread. It has been used by proponents of Proposition 8 to argue against same-sex marriage and to uphold a ban on same-sex adoption.

On the other end of the political spectrum, Barack Obama endorsed the vital role of fathers in a 2008 speech: "Of all the rocks upon which we build our lives, we are reminded today that family is the most important. And we are called to recognize and honor how critical every father is to that foundation."

The lead article in the February issue of Journal of Marriage and Family challenges the idea that "fatherless" children are necessarily at a disadvantage or that men provide a different, indispensable set of parenting skills than women.

"Significant policy decisions have been swayed by the misconception across party lines that children need both a mother and a father. Yet, there is almost no social science research to support this claim. One problem is that proponents of this view routinely ignore research on same-gender parents," said sociologist Timothy Biblarz of the USC College of Letters, Arts and Sciences.

Extending their prior work on gender and family, Biblarz and Judith Stacey of NYU analyzed relevant studies about parenting, including available research on single-mother and single-father households, gay male parents and lesbian parents. "That a child needs a male parent and a female parent is so taken for granted that people are uncritical," Stacey said.

In their analysis, the researchers found no evidence of gender-based parenting abilities, with the "partial exception of lactation," noting that very little about the gender of the parent has significance for children's psychological adjustment and social success.

As the researchers write: "The social science research that is routinely cited does not actually speak to the questions of whether or not children need both a mother and a father at home. Instead proponents generally cite research that compares [heterosexual two-parent] families with single parents, thus conflating the number with the gender of parents."

Indeed, there are far more similarities than differences among children of lesbian and heterosexual parents, according to the study. On average, two mothers tended to play with their children more, were less likely to use physical discipline, and were less likely to raise children with chauvinistic attitudes. Studies of gay male families are still limited.

However, like two heterosexual parents, new parenthood among lesbians increased stress and conflict, exacerbated by general lack of legal recognition of commitment. Also, lesbian biological mothers typically assumed greater caregiving responsibility than their partners, reflecting inequities among heterosexual couples.

"The bottom line is that the science shows that children raised by two same-gender parents do as well on average as children raised by two different-gender parents. This is obviously inconsistent with the widespread claim that children must be raised by a mother and a father to do well," Biblarz said.

Stacey concluded: "The family type that is best for children is one that has responsible, committed, stable parenting. Two parents are, on average, better than one, but one really good parent is better than two not-so-good ones. The gender of parents only matters in ways that don't matter."

We assume that we see things as they really are. But according to a new report in Psychological Science, a journal of the Association for Psychological Science, if we really want something, that desire may influence how we view our surroundings.

Psychological scientists Emily Balcetis from New York University and David Dunning from Cornell University conducted a set of studies to see how our desires affect perception. In the first experiment, participants had to estimate how far a water bottle was from where they were sitting. Half of the volunteers were allowed to drink water before the experiment, while the others ate salty pretzels, thus becoming very thirsty. The results showed that the thirsty volunteers estimated the water as being closer to them than volunteers who drank water earlier.

Our desire for certain objects may also result in behavioral changes. In a separate experiment, volunteers tossed a beanbag towards a gift card (worth either $25 or $0) on the floor, winning the card if the beanbag landed on it. Interestingly, the volunteers threw the beanbag much farther if the gift card was worth $0 than if it was worth $25 — that is, they underthrew the beanbag when attempting to win a $25 gift card, because they viewed that gift card as being closer to them.

These findings indicate that when we want something, we actually view it as being physically close to us. The authors suggest that "these biases arise in order to encourage perceivers to engage in behaviors leading to the acquisition of the object." In other words, when we see a goal as being close to us (literally within our reach), it motivates us to keep on going to successfully attain it.

There is no evidence to support psychological debriefing in schools after traumatic events such as violence, suicides and accidental death, which runs counter to current practice in some Canadian school jurisdictions, according to a commentary http://www.cmaj.ca/embargo/cmaj091621.pdf in CMAJ (Canadian Medical Association Journal) www.cmaj.ca .

Recent systematic reviews indicate that psychological debriefing of adults does not prevent post-traumatic stress disorder and it may even increase the risk of this disorder. While there is little research on the effectiveness and safety of these interventions in schools, "the evidence clearly points to the ineffectiveness of these interventions in preventing post-traumatic stress disorder or any other psychiatric disorder in adults," write Magdalena Szumilas of the Sun Life Financial Chair in Adolescent Mental Health Team, Dalhousie University and coauthors.

Two programs, based on the empirically-supported principles of engendering feelings of safety, calmness, sense of self and community efficacy, connectedness and hope, show promise of effectiveness. Providing Psychological First Aid immediately after an incident and providing cognitive behavioural support for students with persistent distress weeks after a school trauma has ended may be helpful.

They urge that psychological debriefing not be performed after traumatic incidents in schools, and that more research is needed to assess psychological and mental health interventions prior to implementation in schools.
