Throughout the 60s, pioneers in artificial intelligence worked late nights trying to build simple robotic programs capable of finding, fetching and stacking small wooden blocks in patterns. It was one of those apparently simple problems that turn out to be exceptionally difficult, and it led AI scientists to think: perhaps the robot could solve the problem by distributing the work among specialised subagents -- small computer programs that each bite off a piece of the problem. One computer program could be in charge of finding, another could fetch, another could solve stacking. The society-of-mind framework was a breakthrough, but, despite initial excitement, a collection of experts with divided labour has never yielded the properties of the human brain.

The Neuroscience of Looking on the Bright Side Ask a bride before walking down the aisle “How likely are you to get divorced?” and most will respond “Not a chance!” Tell her that the average divorce rate is close to 50 percent, and ask again. Would she change her mind? Unlikely. Psychologists have documented human optimism for decades. To answer these questions we have investigated optimism by using a recent, burgeoning approach in neuroscience: Describing neural activity related to complex behavior with the simple concept of “prediction errors.” The concept of prediction errors was initially put forward in research on artificial intelligence. How have neuroscientists employed the idea of prediction errors to study brain activity? Interestingly, similar patterns of brain activity seem to be at play when participants gamble for money and when they engage in complex social interactions. Prediction errors also appear to be involved in another common human social behavior, when we find out whether another person likes us or not.

The neuroscience of happiness They say money can’t buy happiness. But can a better understanding of your brain? As recent breakthroughs in cognitive science break new ground in the study of consciousness — and its relationship to the physical body — the mysteries of the mind are rapidly becoming less mysterious. Shimon Edelman, a cognitive expert and professor of psychology at Cornell University, offers some insight in “The Happiness of Pursuit: What Neuroscience Can Teach Us About the Good Life.” Salon spoke with Edelman over the phone about the brain as computer, our cultural investment in happiness, and why knowing how our brains work might make us happier. In the book, you approach neuroscience from a popular perspective, using language and allegories laypeople can understand. Well, I think the principles in question are actually pretty accessible on what you call a superficial level. Well, if pursuit is the key to happiness, is this kind of happiness sustainable? That’s a really good question.

Everyday Stress Can Shut Down the Brain's Chief Command Center The entrance exam to medical school consists of a five-hour fusillade of hundreds of questions that, even with the best preparation, often leaves the test taker discombobulated and anxious. For some would-be physicians, the relentless pressure causes their reasoning abilities to slow and even shut down entirely. The experience—known variously as choking, brain freeze, nerves, jitters, folding, blanking out, the yips or a dozen other descriptive terms—is all too familiar to virtually anyone who has flubbed a speech, bumped up against writer’s block or struggled through a lengthy exam. For decades scientists thought they understood what happens in the brain during testing or a battlefront firefight.

The Upside of Pessimism The theory of defensive pessimism suggests that imagining—and planning for—worst-case scenarios can be more effective than trying to think positively. I have pretty low expectations for this article. Oh sure, I spent a lot of time on it, and I personally think it’s a great read. But I’m kind of worried that you will hate it. Worse yet, I’m afraid you’ll hate me for writing it. Or at least, that’s how I would start out thinking if I were prone to defensive pessimism, a phenomenon in which people imagine worst-case scenarios in order to manage their anxiety. This type of negativity might sound like apostasy by American standards. I recently spoke with Norem, a pioneer of the defensive pessimism theory. A lightly edited transcript of our conversation follows, and you can take a test to find out if you’re a defensive pessimist here. Olga Khazan: What is defensive pessimism? Khazan: How would I apply this in real life? Norem: Public speaking is my favorite example.

U.S. researchers map emotional intelligence of the brain We tend to think of reason and emotion as being two different things, but it turns out that there may not be a choice between the heart and the head. A University of Illinois team, led by neuroscience professor Aron Barbey, has made the first detailed 3D map of emotional and general intelligence in the brain, that shows a strong overlap of general and emotional intelligence. Reason and emotions aren’t opposites, but rather two types of intelligence or, perhaps, two aspects of one intelligence. Reason comes under the heading of general intelligence. There are a number of theories about how general and emotional intelligence are related. Relationships between general and emotional intelligence The study was based on computed tomography (CT) scans taken of the brains of 152 US Vietnam War veterans. The CT scans provided the first detailed 3D map of the regions of the brain associated with general and emotional intelligence. In the video below, Aron Barbey discusses the study.

Why Emotion Will Usually Outweigh Logic In The Audience’s Brains | Horace Mann League Blog Many people like to think that business is all about logic, and that customers behave having rationally analysed all available data, considered the various pros and cons of different courses of action and come to a logical conclusion. Although it’s very difficult for very logical people to understand (e.g. accountants, engineers, IT professionals), this could not be further from the truth, as the quote above from Buck Rogers of IBM demonstrates (and he was talking about mainframe computers!). The reality is that a high percentage of the time people make decisions based purely on emotion. ay in the centre of the brain and is primeval. The Neocortex is a much more recent development, in evolutionary terms. However, a lot of the time this route ‘short circuits’ and emotions are triggered automatically, with the Cortex being left out. This happens in all brains, but more frequently in some people than others. He could have just said, “The world is watching this election.”

The Neuroscience of Self-Esteem, Self-Criticism and Self-Compassion All the emphasis on self-esteem building in recent decades has done little to instruct people on what to do when they hit a bump in the road. Most of us, research shows, unleash our inner critic – even if the hardship is brought on by age, illness or another inevitable part of life. Recently, scientists such as Paul Gilbert of Kingsway Hospital in the United Kingdom and Kristin Neff of the University of Texas at Austin, have suggested being self-compassionate, rather than self-critical, especially in rough times, is more likely to help us rebound and may lead to greater success and happiness in the long run. This is not just semantics or new-age feel-good fluff. The "drive" system Likely linked to self-esteem, this system, which is thought to rely heavily on dopamine, compels us to pursue resources, mates, skills, status and so on, Gilbert told LiveScience. The threat-protection system For many of us, these first two systems dominate. Luckily, there is another option (and another system).

Emotional Wiring Different in Men and Women Men and women are actually from the same planet, but scientists now have the first strong evidence that the emotional wiring of the sexes is fundamentally different. An almond-shaped cluster of neurons that processes experiences such as fear and aggression hooks up to contrasting brain functions in men and women at rest, the new research shows. For men, the cluster "talks with" brain regions that help them respond to sensors for what's going on outside the body, such as the visual cortex and an area that coordinates motor actions. For women, the cluster communicates with brain regions that help them respond to sensors inside the body, such as the insular cortex and hypothalamus. "Throughout evolution, women have had to deal with a number of internal stressors, such as childbirth, that men haven't had to experience," said study co-author Larry Cahill of the University of California Irvine. Cahill and his co-author Lisa Kilpatrick, scanned the brains of 36 healthy men and 36 healthy women.

Like it Or Not, Emotions Will Drive the Decisions You Make Today Your emotions will drive the decisions you make today, and your success may depend upon your ability to understand and interpret them. When an emotion is triggered in your brain, your nervous systems responds by creating feelings in your body (what many people refer to as a "gut feeling") and certain thoughts in your mind. A great deal of your decisions are informed by your emotional responses because that is what emotions are designed to do: to appraise and summarize an experience and inform your actions. But if an emotion is triggered, just how much should you pay attention to your visceral response and the thoughts it creates? Emotions are not particularly sophisticated or precise, but their speed and utility make up for what they lack in sophistication and precision. You may think that the best course of action is to suppress or ignore an intense emotion rather than figure it out. Emotions are behind many complex dynamics in business and personal relationships.

10 Ways Gratitude Can Change Your Life & 4 Step Gratitude Plan Gratitude can motivate others, increase self-control, build social ties and more…plus 4-step gratitude plan. Gratitude is the new miracle emotion. Although gratitude has been around for as long as human beings, it’s only recently started to get the big thumbs-up from science. So here are 10 ways gratitude can change your life, followed by a quick 4-step plan to help maximise your own gratitude, whatever level you start from. There’s even a trick for those suffering from ‘gratitude burnout’. 1. Gratitude is different things to different people: amongst them could be counting your blessings, savouring what life has given you, thanking someone or wondering at the natural world. Whatever form it takes, one of the best known and most researched effects of practicing gratitude is it makes you happier. Participants in one study were 25% happier, on average, after practicing a little gratitude over a 10-week period. 2. Gratitude isn’t just about feeling better, it’s also about thinking better. 3. 4.
