Kids' "Paper Laptop" Designs

Original image

Several months back, Amy Tiemann posted A kid's-eye view of laptop design on the CNET news blog. The post discussed a "mini-laptop club" at a local elementary school in which kids designed theoretical laptops using pieces of construction paper. The laptop designs employed unusual, kid-centric keyboard designs, including dedicated keys for "movie selection," "shop," "pet shop," "Hamster," and "HP [Harry Potter] trivia." Rosecrans Baldwin followed up recently with The Laptop Club, an interview with Tiemann including more images of the paper laptops (be sure to click the little 'next' button below the big purple image to see them). From Baldwin's article:

A lot of the children’s keyboards have buttons dedicated to different ways to shop, or to pop-culture icons. Where is this coming from?

I used to suspect that the idea of Tween Culture was an urban myth created by marketers, but now I believe that wherever it’s coming from, it is a real phenomenon. Eight years old appears to be a watershed year for many girls in which they begin to participate in pop culture and also crystallize their social structure. Knowing who your friends are, and either committing to a best friend or figuring out how to remain friends with everyone, are very important. That’s what fascinated me about their laptops. It was a way to demonstrate their knowledge of pop culture and social networks. Having your name on your friend’s keyboard is a little like being in someone’s “Top 8 friends” on MySpace. And yet these kids most likely don’t even know about MySpace yet.

Here's a sample "paper laptop":

This all reminds me of being eight years old and hearing about The Legend of Zelda on the school bus one day, then attempting to recreate the game from memory using the word processor on my home PC. (It was more successful as a pure thought experiment.) These "laptop" designs are clearly indicative of what kids think computers and the internet are useful for, more than realistic designs for laptops -- but there's a lot of surprising information in the button labels kids put on their paper laptop keyboards.

Scientist Asks: Why Do We Weep?

Sometimes we see the tears coming, and sometimes they catch us off guard; we find ourselves weeping without knowing why. It's a personal problem, but it's a scientific one, too: Why do people weep? What purpose does it serve? One expert attempts to answer these questions in a new article in the journal New Ideas in Psychology.

Article author Carlo V. Bellieni is a pediatrician and a bioethicist at Siena University Hospital in Italy. His previous studies have focused on children's emotional well-being and babies' crying and pain. For his latest paper, he examined data and observations on weeping from more than 70 studies and books from researchers stretching back all the way to Charles Darwin.

His conclusion? Weeping is "a complex phenomenon."

For starters, Bellieni writes, weeping is similar to crying, but it's not the same thing. Crying is typically a reaction to pain or anger. It's audible and physical, increasing heart rate, affecting breathing, and contorting the face and body. A crying person's voice changes, and their body makes more stress hormones like adrenaline. And while they don't shed tears, other animals cry, too.

Weeping, on the other hand, appears to be uniquely human. It's what happens when the cup of our emotions runneth over. We cry when we drop a cinderblock on our foot. We weep at funerals, and at weddings.

As Bellieni discovered, there are many theories on how we cry and weep, and where the tears come from. Some researchers have argued that we make tears to return ourselves to the soothing, fluid environment of the womb. Others theorize that our bodies start extruding tears (and snot) to keep our nose and throat from drying out as our breathing intensifies. Darwin's hypothesis was that the tears are a byproduct of scrunching up our faces, including the tear-production glands.

None of these theories seem especially plausible, Bellieni writes. So for now, the answer to the physical question is, "We don't really know."

The emotional and social sides of the weeping equation are slightly more straightforward.

Weeping is a form of releasing intense emotion and physical tension. When we weep, we tell our body that it's okay to relax. This helps us reset our system, so to speak, and move on.

And seeing someone weep makes us want to help them, Bellieni says. Weeping makes other people want to help us. Visible sorrow is an opportunity to strengthen social ties. And among social animals like us, strong bonds mean a better chance of survival.

It's wrong to think of weeping as wimpy or weak, Bellieni says. In fact, it's "a strong behavior with positive effects on health and social interaction."

"In the light of these data," he concludes, "weeping appears to be a primal and important human behavior that deserves more attention."

If You’ve Ever Seen a Ghost, Science May Explain Why

Despite all the reports of ghost sightings (28 percent of Americans report having ghostly encounters), there’s zero evidence to support the presence of supernatural beings among us. Science may not prove the existence of ghosts, but it can help explain why people think they see ghosts in the first place.

In this video from Vox, paranormal investigator Joe Nickell identifies some of the phenomena believers may mistake for paranormal activity. One possible explanation is infrasound, or the sound waves that fall beneath levels of human perception. Though we can’t hear these noises firsthand, our bodies sense them in other ways. This can cause chills, feelings of unease and depression, and even hallucinations.

Other contributors may include sleep paralysis (when you wake up while your body is immobile and experience waking nightmares) and grief. There are also a few less common possibilities that aren’t covered in the video below: Mold poisoning, for instance, can lead to irrational fear and dementia. Suddenly, a visit from a poltergeist doesn’t sound so scary.
