Computers, like those that power self-driving cars, can be tricked into mistaking random scribbles for trains, fences and even school busses. People aren’t supposed to be able to see how those images trip up computers but in a new study, Johns Hopkins University researchers show most people actually can.

Owls Help JHU Scientists Unlock Secret of How the Brain Pays Attention
By studying barn owls, scientists at Johns Hopkins University believe they’ve taken an important step toward solving the longstanding mystery of how the brain chooses what most deserves attention.
Scientists Find Brain Signal That Might Help Us Judge the Holiday Buffet
At holiday buffets and potlucks people make quick calculations about which dishes to try and how much to take of each. Johns Hopkins University neuroscientists have found a brain region that appears to be strongly connected to these food preference decisions.
Gambling Monkeys Help Scientists Find Brain Area Linked to High-Risk Behavior
Monkeys who learned how to gamble have helped researchers pinpoint an area of the brain key to one’s willingness to make risky decisions.
When There’s an Audience, People’s Performance Improves
Often people think performing in front of others will make them mess up, but a new study led by a Johns Hopkins University neuroscientist found the opposite: being watched makes people do better.
JHU Records Brain Activity of a Free-flying Bat
Johns Hopkins University researchers have developed a way to study the brain of a bat as it flies, recording for the first time what happens as an animal focuses its attention.
JHU Finds Letter We’ve Seen Millions of Times, Yet Can’t Write
Despite seeing it millions of times in pretty much every picture book, every novel, every newspaper and every email, Johns Hopkins University researchers have found people are essentially unaware of the most common version of the lowercase print g.
JHU Finds How Brain Instantly Tells Trash from Treasure
Johns Hopkins University neuroscientists have found how the brain can detect an object’s value almost as soon as we see it.
Mind of a Medalist: Scientists Explain How the Brain Can Lead to Olympic Gold
Any athlete who’s made it to the Olympics has speed or strength or whatever physical skills it takes to lead the world in their sport. But Johns Hopkins University scientists say those who ultimately bring home gold have also honed the mind of a medalist.
JHU Finds Why We Can’t Always Stop What We’ve Started
When we try to stop a body movement at the last second, perhaps to keep ourselves from stepping on what we just realized was ice, we can’t always do it — and Johns Hopkins University neuroscientists have figured out why.
Study: Junk Food Almost Twice as Distracting as Healthy Food
Even when people are hard at work, pictures of cookies, pizza and ice cream can distract them — and these junk food images are almost twice as distracting as health food pictures, concludes a new Johns Hopkins University study, which also found that after a few bites of candy, people found junk food no more interesting than kale.
Johns Hopkins Finds Training Exercise That Boosts Brain Power
One of the two brain-training methods most scientists use in research is significantly better in improving memory and attention, Johns Hopkins University researchers found. It also results in more significant changes in brain activity.
Pilot Program Will Test Novel Approach to Teaching Science
Though scientists know children with strong spatial thinking skills have an edge in science, technology, engineering and math, and that those skills are teachable, no one has formally infused them into a working elementary curriculum. With a $1.4 million federal grant, Johns Hopkins University researchers will co-develop and test such a program for third-grade science classes.
It’s a Bird, It’s a Plane, It’s – a Key Discovery About Human Memory
As Superman flies over the city, people on the ground famously suppose they see a bird, then a plane, and then finally realize it’s a superhero. But they haven’t just spotted the Man of Steel – they’ve experienced the ideal conditions to create a very strong memory of him.
Johns Hopkins University cognitive psychologists are the first to link human’s long-term visual memory with how things move. The key, they found, lies in whether we can visually track an object. When people see Superman, they don’t think they’re seeing a bird, a plane and a superhero. They know it’s just one thing – even though the distance, lighting and angle change how he looks.
The Surprising Thing Blind People Doing Math Reveals About the Brain
Human babies and even animals have a basic number sense that many believe evolves from seeing the world and trying to quantify all the sights. But vision has nothing to do with it – Johns Hopkins University neuroscientists have found that the brain network behind numerical reasoning is identical in blind and sighted people.
Kill Them With Cuteness: The Adorable Thing Bats Do to Catch Prey
Bats’ use of echolocation to detect, track and catch prey is well documented. But this Johns Hopkins team is the first to show how the relatively mysterious head and ear movements factor into the hunt.
Researchers Find Brain’s ‘Physics Engine’
Whether or not they aced it in high school, human beings are physics masters when it comes to understanding and predicting how objects in the world will behave. A Johns Hopkins University cognitive scientist has found the source of that intuition, the brain’s “physics engine.”
The Brain’s Super-Sensitivity to Curbs
Humans rely on boundaries like walls and curbs for navigation, and Johns Hopkins University researchers have pinpointed the areas of the brain most sensitive to even the tiniest borders.
What Free Will Looks Like in the Brain
Johns Hopkins University researchers are the first to glimpse the human brain making a purely voluntary decision to act.
