This Is Your Brain on Puns

Q. What do vegan zombies eat?
A. Graaaaaaaaaaaaains. 

If that joke made you groan like the undead, thank your bilateral processing abilities. Researchers studying the neuroscience of puns say that understanding them, even the bad ones, requires cooperation between both sides of the brain. They published their research in the journal Laterality: Asymmetries of Body, Brain and Cognition. 

Humor has a reputation for being transgressive, but all that boundary-pushing is only possible thanks to a system of internal rules. From knock-knock jokes to digs on someone’s mama, each class has its own standardized scaffolding. Some philosophers argue that humor itself depends on a formula: taking something familiar and giving it an unexpected—but not upsetting—twist. 

This “benign violation” setup is also at the heart of the pun. The joke up top takes a reader’s familiarity with the cliché of the lurching, brain-craving zombie, then uses a rhyme to add a surprising shade of meaning. Yes, we know that dissecting jokes isn’t funny. We’re done now.

Neuroscientists at the University of Windsor wondered how our brains would parse the two-step process of understanding puns. They were specifically curious to find out how the work was divvied up between the brain’s left and right hemispheres. 

To find out, they brought volunteers into the lab and sat them down in front of computers, which proceeded to display a series of easy, cheesy puns. (Ex.: “They replaced the baseball with an orange to add some zest to the game.”) Some of the puns showed up on the left side of the screen, where they would be processed first by the right side of the brain. The rest showed up on the right. The participants were timed to see how long it took them to get each joke, such as it was. 

The results showed that participants were quicker on the uptake when their puns appeared on the right side of the screen—that is, starting with the left side of their brains. This makes sense, co-author Lori Buchanan told Scientific American: “The left hemisphere is the linguistic hemisphere, so it’s the one that processes most of the language aspects of the pun, with the right hemisphere kicking in a bit later.” 

Understanding a pun, they found, requires input from both hemispheres. The left side introduces the standard, linguistic part of the sentence or joke—essentially setting up the setup—while the right side analyzes the punchline’s double meaning. 

That's probably more thought than most puns deserve. 

Kodak’s New Cameras Don't Just Take Photos—They Also Print Them

Snapping a photo and immediately sharing it on social media is definitely convenient, but there’s still something so satisfying about having the printed photo—like you’re actually holding the memory in your hands. Kodak’s new STEP cameras now offer the best of both worlds.

As its name implies, the Kodak STEP Instant Print Digital Camera, available for $70 on Amazon, lets you take a picture and print it out on that very same device. Not only do you get to skip the irksome process of uploading photos to your computer and printing them on your bulky, non-portable printer (or worse yet, having to wait for your local pharmacy to print them for you), but you never need to bother with ink cartridges or toner, either. The Kodak STEP comes with special 2-inch-by-3-inch printing paper inlaid with color crystals that bring your image to life. There’s also an adhesive layer on the back, so you can easily stick your photos to laptop covers, scrapbooks, or whatever else could use a little adornment.

For those of you who want to give your photos some added flair, you might like the Kodak STEP Touch, available for $130 from Amazon. It’s similar to the regular Kodak STEP, but the LCD touch screen allows you to edit your photos before you print them; you can also shoot short videos and even share your content straight to social media.

If you want to print photos from your smartphone gallery, there's the Kodak STEP Instant Mobile Photo Printer. This portable $80 printer connects to any iOS or Android device with Bluetooth capabilities and can print whatever photos you send to it.

The Kodak STEP Instant Mobile Photo Printer connects to an app that allows you to add filters and other effects to your photos. Kodak

All three Kodak STEP devices come with some of that magical printer paper, but you can order additional refills, too—a 20-sheet set costs $8 on Amazon.

Head to any given park on any given sunny summer day, and you’ll likely encounter a people-watcher’s paradise. And to keep us occupied on the rainy days, online watch retailer Watches2U has turned all those sunbathers, joggers, dog-walkers, and skittery squirrels into an entertaining brainteaser.

The left and right images below are almost identical, save for 10 tiny discrepancies that you may not notice at first glance. Once you think you’ve spotted them all (or given up), scroll to the bottom to reveal the answers.

Which type of park-goer are you?Watches2U

As any good Parks and Recreation fan knows, even the smallest park can be a symbol of community and a saving grace for city-dwellers short on yard space. And national parks, like Yellowstone and the Grand Canyon, can be full-fledged vacation spots. They often also help protect wildlife in the region. Great Smoky Mountains National Park, for example, is known as the “salamander capital of the world,” and Theodore Roosevelt National Park is home to hundreds of bison, which were once on the brink of extinction.

In the midst of the current pandemic, a visit to your local park might look a little different than it usually does. Masks and social distancing are musts, and hand sanitizer should flow freely. And if you’re road-tripping a little farther from home, here are some expert tips for doing it safely.
