When faced with a difficult decision, it is often suggested to “sleep on it” or take a break from thinking about the decision in order to gain clarity.
But new brain imaging research from Carnegie Mellon University, published in the journal “Social Cognitive and Affective Neuroscience,” finds that the brain regions responsible for making decisions continue to be active even when the conscious brain is distracted with a different task. The research provides some of the first evidence showing how the brain unconsciously processes decision information in ways that lead to improved decision-making.
“This research begins to chip away at the mystery of our unconscious brains and decision-making,” said J. David Creswell, assistant professor of psychology in CMU’s Dietrich College of Humanities and Social Sciences and director of the Health and Human Performance Laboratory. “It shows that brain regions important for decision-making remain active even while our brains may be simultaneously engaged in unrelated tasks, such as thinking about a math problem. What’s most intriguing about this finding is that participants did not have any awareness that their brains were still working on the decision problem while they were engaged in an unrelated task.”
For the study, Creswell, recent CMU graduate James K. Bursley and Northeastern University’s Ajay B. Satpute presented 27 healthy adults with information about cars and other items while undergoing neuroimaging. Then, before being asked to make decisions about the items, the participants had to complete a difficult distractor task — memorizing sequences of numbers — to prevent them from consciously thinking about the decision information.
The results included three main findings. First, the team confirmed previous research demonstrating that a brief period of distraction — in this case two minutes — produced higher quality decisions about the cars and other items. But did this effect occur because the distraction period provided an opportunity for the brain to take a break from decision-making and then return to the problem with a fresh look? Or alternatively, does the brain continue to unconsciously process decision information during this distraction period? This research supports the latter unconscious processing explanation.
When the participants were initially learning information about the cars and other items, the neuroimaging results showed activation in the visual and prefrontal cortices, regions that are known to be responsible for learning and decision-making. Additionally, during the distractor task, both the visual and prefrontal cortices continued to be active — or reactivated — even though the brain was consciously focused on number memorization.
Third, the results showed that the amount of reactivation within the visual and prefrontal cortices during the distractor task predicted the degree to which participants made better decisions, such as picking the best car in the set.
“We all face difficult problems we need to solve on a regular basis,” Creswell said. “Whether it’s buying a new car, finding a new apartment to rent, or seeking out a new dating partner on social networking sites. This study provides some of the first clues for how our brains process this information for effective problem-solving and decision-making.”
Bursley (DC’12), who joined CMU’s Health and Human Performance Laboratory as a freshman, spent his undergraduate career working on this research and related studies. To support his work, he received a Small Undergraduate Research Grant (SURG) and Summer Undergraduate Research Fellowship (SURF). Bursley also received a Rothberg Research Award in Human Brain Imaging, made possible by Carnegie Mellon alumnus and trustee Jonathan M. Rothberg (E’85), founder of four genetics companies aimed at improving human health.
“Carnegie Mellon was the perfect place to carry out this work because there’s a significant focus here on pursuing new directions in mind-brain research,” Bursley said. “This study is really a starting point. We also are using brain imaging to see if we find the same reactivation patterns in learning tasks that we saw here in decision-making.”
CMU’s Department of Psychology has helped to establish Carnegie Mellon as a world leader in brain sciences. The university recently launched a Brain, Mind and Learning initiative to build from its research excellence in psychology, computer science and computation to continue to solve real-world problems.

Situationist friend, Amy Cuddy, delivers a fascinating TedTalk on how body language affects how others see us and on how we see ourselves. Cuddy shows how “power posing” — standing in a posture of confidence, even when we don’t feel confident — can affect testosterone and cortisol levels in the brain, and might even have an impact on our chances for success.
A few years ago, a research psychologist at Stanford University named Jeremy Bailenson effectively proved the soundness of Anderson’s recruitment methods (pdf). A week before the 2004 presidential election, Bailenson asked a bunch of prospective voters to look at photographs of George W. Bush and John Kerry and then give their opinions of the candidates. What the voters didn’t know was that the photographs had been doctored: each voter’s own visage had been subtly morphed together with that of one of the candidates.
In this and two follow-up experiments, Bailenson found what Rudy Rucker, the novelist who wrote Software, would have predicted: voters were significantly more likely to support the candidate who had been made to look like them. What’s more, not a single voter detected that it was, in part, his or her own face staring back.
In another experiment (pdf), Bailenson outfitted college students with head-mounted virtual-reality displays and then sat them across a digital table from an artificial-intelligence agent—a computer program with a human face. The students then listened as the “agent” delivered a short persuasive speech. When the agent was programmed to mimic a student’s facial movements on a four-second delay—a tilt of the chin, a look to the left, a downward glance—the students found it more likeable and compelling. And like the prospective voters, the students showed no sign that they knew they were being mimicked. Nothing, it seems, is more persuasive than a mirror.
The coming explosion of immersive digital technology, combined with recent progress in unlocking how the mind works, will soon revolutionize our lives in ways only science fiction has imagined. In Infinite Reality, Jeremy Bailenson (Stanford University) and Jim Blascovich (University of California, Santa Barbara)—two of virtual reality’s pioneering authorities whose pathbreaking research has mapped how our brain behaves in digital worlds—take us on a mind-bending journey through the virtual universe.
Infinite Reality explores what emerging computer technologies and their radical applications will mean for the future of human life and society. Along the way, Bailenson and Blascovich examine the timeless philosophical questions of the self and “reality” that arise through the digital experience; explain how virtual reality’s latest and future forms—including immersive video games and social-networking sites—will soon be seamlessly integrated into our lives; show the many surprising practical applications of virtual reality, from education and medicine to sex and warfare; and probe further-off possibilities like “total personality downloads” that would allow your great-great-grandchildren to have a conversation with “you” a century or more after your death.

Part 3 of the BBC’s Remarkable Three-Part Series “The Men Who Made Us Fat”:
Jacques Peretti examines assumptions about what is and is not healthy. He also looks at how product marketing can seduce consumers into buying supposed ‘healthy foods’ such as muesli and juices, both of which can be high in sugar.
He speaks with Simon Wright, an ‘organic consultant’ for Sainsbury’s in the 1990s, who explains how the food industry cashed in on the public’s concerns around salmonella, BSE and GM crops. By 1999 the organic industry was worth over £605M, a rise of 232% within two years.
How did the mainstream food producers compete? Peretti speaks with Kath Dalmeny, former policy director at the Food Commission, who explains some of the marketing strategies used by mainstream food producers to keep our custom.
The programme also explores the impact of successive government initiatives and health campaigns, such as the proposal of ‘traffic light labelling’, the introduction of which the food industry lobbied hard against.
But in 2012, when we have an Olympic Games sponsored by McDonalds and Coca Cola, has anything changed?

Part 2 of the BBC’s Remarkable Three-Part Series “The Men Who Made Us Fat”:
Jacques Peretti investigates how the concept of ‘supersizing’ changed our eating habits forever. How did we – once a nation of moderate eaters – start to want more?
Speaking to Mike Donahue, former McDonalds Vice President, Peretti explores the history behind the idea of supersizing. 40 years ago, McDonalds hired David Wallerstein, a former cinema manager who had introduced the idea of selling larger popcorn servings in his Chicago cinema. Wallerstein realised that people would eat more but they didn’t like the idea of appearing gluttonous by going back for seconds. By increasing the portion sizes and the cost, he could sell more food. In 1972, he introduced the idea to McDonalds and their first large fries went on sale.
By the 1980s, we were eating more – and eating more often. Perretti speaks with industry professionals to examine the story behind the introduction of value meals, king-size snacks and multi-buy promotions. How did the advertising industry encourage us to eat more often?
The programme also explores the developments in dietary advice – by 2003, the Chief Medical Officer was warning of an ‘obesity time bomb.’ Peretti speaks to obesity expert Professor Philip James, who made recommendations in his 1996 report that the food industry should cease targeting children in their advertisements. He also speaks with Professor Terry Wilkin, who led a pioneering study into childhood weight gain; and former Labour MP David Hinchliffe, who chaired the 2003 Parliamentary Select Committee on Health.

From Introduction of BBC’s Remarkable Three-Part Series “The Men Who Made Us Fat”:
Around the world, obesity levels are rising. More people are now overweight than undernourished. Two thirds of British adults are overweight and one in four of us is classified as obese. In the first of this three-part series, Jacques Peretti traces those responsible for revolutionising our eating habits, to find out how decisions made in America 40 years ago influence the way we eat now.
Peretti travels to America to investigate the story of high-fructose corn syrup. The sweetener was championed in the US in the 1970s by Richard Nixon’s agriculture secretary Earl Butz to make use of the excess corn grown by farmers. Cheaper and sweeter than sugar, it soon found its way into almost all processed foods and soft drinks. HFCS is not only sweeter than sugar, it also interferes with leptin, the hormone that controls appetite, so once you start eating or drinking it, you don’t know when to stop.
Endocrinologist Robert Lustig was one of the first to recognise the dangers of HFCS but his findings were discredited at the time. Meanwhile a US Congress report blamed fat, not sugar, for the disturbing rise in cardio-vascular disease and the food industry responded with ranges of ‘low fat’, ‘heart healthy’ products in which the fat was removed – but the substitute was yet more sugar.
Meanwhile, in 1970s Britain, food manufacturers used advertising campaigns to promote the idea of snacking between meals. Outside the home, fast food chains offered clean, bright premises with tempting burgers cooked and served with a very un-British zeal and efficiency. Twenty years after the arrival of McDonalds, the number of fast food outlets in Britain had quadrupled.

Host Harry Kreisler welcomes writer Michael Pollan for a discussion of the agricultural industrial complex that dominates consumer choices about what to eat. He explores the origins, evolution and consequences of this system for the nations health and environment. He highlights the role of science, journalism, and politics in the development of a diet that emphasizes nutrition over food. Pollan also sketches a reform agenda and speculates on how a movement might change Americas eating habits. He also talks about science writing, the rewards of gardening, and how students might prepare for the future.
