  • Are children today really suffering nature deficit disorder (TM)?

    …7;t have television to keep them indoors, they also didn’t have child labor laws. The result was that children who once might have been at work at age 4 in a field were now at work at age 3 or 4 in a factory, putting in 12 or so hours a day before stepping out into the coal-smoked, animal-dung-scented air of the city.  Child labor wasn’t something confined to Industrial Revolution Britain, and it continues today, both for agriculture…

  • Sesame Street helps unlock the secrets to the brain during children’s learning

    …s what’s seen in the brain while a person builds a treehouse? In this study, the researchers found a partial answer to exactly that kind of question, and the answer is no. The children in study, ranging in age from 4 to 11 and all typically developing, watched the same 20-minute montage of short clips with Big Bird, Cookie Monster, the Count, Oscar and the rest of the gang teaching numbers and letters, shapes and colors, planets and countri…

  • SCOTUS justices can’t find science on same-sex marriage

    …script here). Unless the ancient Greeks had cell phones and wireless, he’s wrong on that. And based on that reasoning, it would have been just fine for a Supreme Court justice hearing Brown vs. the Board of Education in 1954 to point out that school desegregation was a concept newer even than television. Does that mean anything? Solicitor General Donald Verrilli, presenting the case before the court, offered up another comparison: Well, the…

  • About that 1 in 50 autism number

    Not all numbers are created equal. by Emily Willingham         The US Centers for Disease Control and Prevention (CDC) has released new figures for autism prevalence in the United States. They now give a prevalence of 1 in 50, but this story, like most autism-related stories, goes deeper than the numbers. First, this prevalence estimate doesn’t focus only on 8-year-olds, the population used for deriving the 1 in 88 number reported in 2012….

  • On this Father’s Day, let’s remember the allofathers, too

    A big brother, practicing the art of allofathering.

  • Motherhood Defined: It is in the heart of the beholder

    “Motherhood”: Sculpture at the Catacumba Park, Rio de Janeiro, Brazil Motherhood.  It can mean many things, and our own definition of it is largely defined by our individual experiences.  To one person, motherhood might simply mean the act of raising children; to another, motherhood might be what defines them.   It is not uncommon to generalize the concept of “motherhood” and lump everyone who upholds a singl…

    …nknown HIV levels near the time of delivery, regardless of whether they were taking recommended antiretroviral drugs during pregnancy. The guidelines state that when there is a low rate of transmission (viral loads lower than 1000 copies/mL), the benefits of a scheduled c-section are unclear. Dr. Levison, an obstetrician/gynecologist at Baylor College of Medicine, Houston, TX, says that in her practice, women rarely need a cesarean section. The n…

    …rently September of 2012, and the numbers last reported to the CDC were at 29,834, and that doesn’t even include over 3,700 cases in Minnesota that haven’t been officially reported to the CDC yet. These numbers, which include 14 deaths (primarily of babies under 3 months), may very well end up doubling the 2011 total of 18,719 if they continue at the current rate through the end of the year. It’s the biggest pertussis outbreak since 1959. Not…

  • Autism and the DSM-5

    …questions in the context of these criteria. I’ve expanded on a couple of these reports at length elsewhere, as have others with an interest in the subject. The short version is that studies overall indicate that at the least, 10% of people who would currently have an autism diagnosis under the DSM-IV-TR criteria would lose that diagnosis under the DSM-5, and some studies go as high as 55% in their estimates. Even more troubling? The committee’s s…
