A simple brain-training game could help children choose healthy snacks instead of chocolate and sweets, according to a new study.
Children who played a seven-minute game devised by University of Exeter psychologists made healthier choices when asked to pick foods afterwards.
The game involves reacting to images of healthy food by pressing a button, and doing nothing if unhealthy foods are shown.
"The sight of foods like chocolate can activate reward centres in the brain at the same time as reducing activity in self-control areas," said Lucy Porter, the lead researcher on the project.
"Our training encourages people to make a new association -- when they see unhealthy food, they stop.
"Many health promotion schemes rely on education and willpower and require a lot of time, staff and money, but our game potentially sidesteps these issues by creating a free, easy tool for families to use at home.
"The research is at an early stage and we need to investigate whether our game can shift dietary habits in the long-term, but we think it could make a useful contribution."
The researchers ran two experiments, and in total more than 200 schoolchildren aged 4-11 were shown images of healthy and unhealthy foods.
Alongside each image was a cartoon face -- happy for healthy food, sad for unhealthy food.
Children had to hit the spacebar when they saw a happy face, and do nothing if they saw a sad face -- they were not told that the game had anything to do with healthy or unhealthy food.
Afterwards, they played a shopping game where they had to choose a limited number of food items in one minute.
"We didn't see a total turnaround in favour of choosing healthy options, but these increased from about 30% of foods chosen to over 50% in children who did the brain training," said Porter.
"Age did not affect whether the game worked or not, meaning that children as young as four can benefit from playing.
Meanwhile children in control groups -- who were shown happy and sad faces mixed evenly between healthy and unhealthy foods, or images which were not food-related at all -- showed no change in food choices.
Similar research by the study's senior author, Dr Natalia Lawrence, has already led to the creation of an app which helps adults avoid unhealthy foods and lose weight.
"It's encouraging to see that this simple computer game has the potential to improve food choices in young children as well as in adults" she said.
"As we all know, it's incredibly important to encourage healthy eating habits from a young age; children in the UK eat on average three times too much sugar and not enough fruit and vegetables.
"This game is one simple and relatively fun way of trying to redress the balance."
Porter added: "This easy game does all the hard work for you. It's not about learning anything consciously, it's about working with automatic responses.
She acknowledges that some people might feel uneasy about this, but she explains: "Playing this game is optional -- unlike the constant stream of advertising designed to brainwash children.
"This game won't eliminate the effect of junk food advertising or price promotions, but it might give people a little bit of control back."

Playing a computer game nonstop is just an addiction
Dear Annie: I don't know what to do.
I recently retired. My husband is still working.
In the past few years, he has started playing a computer game. This is not one of the ones that involve other players; it involves only him.
At first, he did it for only an hour or two. Now he starts when he gets home from work and plays until bedtime, usually only stopping for dinner. On weekends, except for mowing the lawn and doing a few other tasks, he plays from morning until bed.
He has no interest in doing any of the things we used to do, and I am worried about the future when he retires.
We once talked about all the things we could do when we are both retired, but I can't see that happening anymore. He used to be good company; we used to go places and do things together. I have many interests and outside activities, but I miss the man I married. I am very sad and not looking forward to a future of this. He refuses to consider counseling, saying that I am the one with a problem.
I guess that is true, because he is apparently happy with the game. Do you have any suggestions? – Lonely
Dear Lonely: Your husband is playing a losing game with addiction.
Seeing as he's defensive and insistent that he doesn't have a problem, you might try shifting the focus to your marriage and the way his behavior is impacting you. Then suggest marriage counseling. An objective third-party might be the game changer he needs.
I would also recommend contacting On-Line Gamers Anonymous. It offers help for people in your position.
One of the first things it emphasizes is to stop enabling the gamer's problematic behavior. "This means refraining from doing anything that makes their life comfortable while they game, such as bringing them meals at the computer," the group says.
Dear Annie: I'm a woman in my early 50s. Eight years ago, I began having messy bathroom-related accidents in my car after eating in restaurants.
Doctors confirmed I had an allergy to gluten – which made sense, seeing as one of my parents has it and I had usually just consumed wheat before having an attack in the car.
Many restaurants and supermarkets are very accommodating. The hardest part is dealing with regular snide comments about my gluten-free diet – people saying I'm just being trendy and I'll get over it.
I'm sure a lot of people are avoiding wheat by choice, but some of us have to do it out of necessity. Please tell your readers to be more discerning. – Frustrated in Framingham
Dear Frustrated: It sounds as if the people making these remarks have some intolerance issues of their own. Gluten-related disorders, such as celiac disease, are very real.
Just because some fad dieters have gravitated toward a gluten-free trend doesn't make it OK to dismiss the issue. Your diet is between you and your doctor. If anyone else wants to judge you, he or she should first walk a mile with your stomach issues.
Dear Annie: There was no response to "Knight's" letter from you in our local paper, so I am sending one.
How chivalrous he is – and self-centered. Many men who "pay" expect something in return that a woman might not care to offer.
Quid pro quo.
This is not about commitment. It is about power, control, intimidation and manipulation.
Treating someone should not be about you; it should be about the other person.
If your date chooses to not accept your offer, it doesn't say anything about you; it says something about the comfort level of your date. – Not a Fan

Is this computer game the most romantic marriage proposal of all time?
Finding the right way to pop the question isn't easy.
The story of how you proposed is told to friends and strangers for the rest of your lives, so you want to choose something that won't fall flat over the dinner table.
And while some people choose to ask over candlelit dinners or iconic landmarks, one romantic developer decided to turn his proposal into a chance to build a customised computer game for his betrothed.
Austin Piech and Lauren Woodrick had been dating for a few years when he decided he wanted to take their relationship to the next level, so he decided to put together a playable proposal for his girlfriend to attempt to complete.
Piech posted a video of his ingenious proposal to YouTube, which has racked up almost 800,000 hits from impressed internet users.
Each level of the clever platform game features memorable moments from Piech's time dating his girlfriend - from their first date venue to holidays they'd taken together over the years.
According to the developer, his partner had no idea that the video game was a proposal - she thought she was just helping him to test out a new computer game he'd been working on.
As she navigates through each difficult level, the camera points out that the engagement ring is hidden behind the computer.
The final level of the game involves passing digital mariachis which, we are told, are 'playing' the same song Piech's grandfather proposed to his grandmother with.
Once she defeats the mariachi players, the credits reveal the message, 'It's dangerous to go alone. Take this!'
At this point, Piech pulls the ring out a ring which he hands over to his crying girlfriend. A tearful Lauren says yes, and the game becomes a success.
The viral video has gathered attention on Reddit today, with commenters remarking on the originality of the proposal.
'I'll marry you,' said user SupMatto.
'Best proposal i've ever seen, nice one bro,' agreed bakerXderek.
Thinking of popping the question? It might be time to book yourself into a coding class.

Humans play computer game using only direct brain stimulation
In the Matrix film series, Keanu Reeves plugs his brain directly into a virtual world that sentient machines have designed to enslave mankind.
The Matrix plot may be dystopian fantasy, but University of Washington researchers have taken a first step in showing how humans can interact with virtual realities via direct brain stimulation.
In a paper published online Nov. 16 in Frontiers in Robotics and AI, they describe the first demonstration of humans playing a simple, two-dimensional computer game using only input from direct brain stimulation -- without relying on any usual sensory cues from sight, hearing or touch.
The subjects had to navigate 21 different mazes, with two choices to move forward or down based on whether they sensed a visual stimulation artifact called a phosphene, which are perceived as blobs or bars of light. To signal which direction to move, the researchers generated a phosphene through transcranial magnetic stimulation, a well-known technique that uses a magnetic coil placed near the skull to directly and noninvasively stimulate a specific area of the brain.
"The way virtual reality is done these days is through displays, headsets and goggles, but ultimately your brain is what creates your reality," said senior author Rajesh Rao, UW professor of Computer Science & Engineering and director of the Center for Sensorimotor Neural Engineering.
"The fundamental question we wanted to answer was: Can the brain make use of artificial information that it's never seen before that is delivered directly to the brain to navigate a virtual world or do useful tasks without other sensory input? And the answer is yes."
The five test subjects made the right moves in the mazes 92 percent of the time when they received the input via direct brain stimulation, compared to 15 percent of the time when they lacked that guidance.
The simple game demonstrates one way that novel information from artificial sensors or computer-generated virtual worlds can be successfully encoded and delivered noninvasively to the human brain to solve useful tasks. It employs a technology commonly used in neuroscience to study how the brain works -- transcranial magnetic stimulation -- to instead convey actionable information to the brain.
The test subjects also got better at the navigation task over time, suggesting that they were able to learn to better detect the artificial stimuli.
"We're essentially trying to give humans a sixth sense," said lead author Darby Losey, a 2016 UW graduate in computer science and neurobiology who now works as a staff researcher for the Institute for Learning & Brain Sciences (I-LABS). "So much effort in this field of neural engineering has focused on decoding information from the brain. We're interested in how you can encode information into the brain."
The initial experiment used binary information -- whether a phosphene was present or not -- to let the game players know whether there was an obstacle in front of them in the maze. In the real world, even that type of simple input could help blind or visually impaired individuals navigate.
Theoretically, any of a variety of sensors on a person's body -- from cameras to infrared, ultrasound, or laser rangefinders -- could convey information about what is surrounding or approaching the person in the real world to a direct brain stimulator that gives that person useful input to guide their actions.
"The technology is not there yet -- the tool we use to stimulate the brain is a bulky piece of equipment that you wouldn't carry around with you," said co-author Andrea Stocco, a UW assistant professor of psychology and I-LABS research scientist. "But eventually we might be able to replace the hardware with something that's amenable to real world applications."
Together with other partners from outside UW, members of the research team have co-founded Neubay, a startup company aimed at commercializing their ideas and introducing neuroscience and artificial intelligence (AI) techniques that could make virtual-reality, gaming and other applications better and more engaging.
The team is currently investigating how altering the intensity and location of direct brain stimulation can create more complex visual and other sensory perceptions which are currently difficult to replicate in augmented or virtual reality.
"We look at this as a very small step toward the grander vision of providing rich sensory input to the brain directly and noninvasively," said Rao. "Over the long term, this could have profound implications for assisting people with sensory deficits while also paving the way for more realistic virtual reality experiences."
