Edge 2011: What Scientific Concept Would Improve Everybody’s Cognitive Toolkit?

December 13, 2011 / Klint Finley

This year’s Edge question was: “What scientific concept would improve everybody’s cognitive toolkit?” There are some good but somewhat boring answers, like Susan Blackmore’s or Kevin Kelly’s. But here are some of the more interesting ones I found:

Stewart Brand: Microbes Run the World

Nicholas Carr: Cognitive Load

Aubrey de Grey: A Sense Of Proportion About Fear Of The Unknown

Jonah Lehrer: Control Your Spotlight

Evgeny Morozov: Einstellung Effect

Jay Rosen: Wicked Problems

Douglas Rushkoff: Technologies Have Biases

Nassim Taleb: Antifragility — or— The Property Of Disorder-Loving Systems

I would especially recommend reading both Carr’s and Lehrer’s.

There are a ton of these, so I haven’t read them all, so there could be some gems out there I missed. What are your favorites?

If I’d been asked, I’d have chosen one of the following:

1. The idea of systematic ideology – that people choose what to believe based on ideology, not reason (an idea also supported by research indicating that facts can actually backfire when trying to change someone’s mind). Systematic ideology, named by George Walford, was proposed in 1947 by Harold Walsby. The idea is now being pursued by the Cultural Cognition Project at Yale Law School, though they don’t use the term and may not be aware of Walsby’s and Walford’s work.

2. The Decline Effect.

The Neuroscience of Video Games, a Review of the Literature

November 23, 2011 / Klint Finley

Gamer

John Walker takes a look at the journal Nature‘s recent Brains On Video Games collection, which includes both possible negative and possible positive outcomes of video game play.

The bad news: much of the positive cognitive gains from video gaming are non-transferable, and gaming may increase both aggression and the symptoms of ADHD. The good news: it doesn’t sound like that should be a problem for people without existing aggressive tendencies or ADHD.

My take-away: if you like playing games, keep playing them. If you don’t, there’s probably not much benefit in starting.

Junk Food May Be As Addictive as Drugs

November 10, 2011 / Klint Finley

Judge Dredd - Sugar bust

Bloomberg reports:

The idea that food may be addictive was barely on scientists’ radar a decade ago. Now the field is heating up. Lab studies have found sugary drinks and fatty foods can produce addictive behavior in animals. Brain scans of obese people and compulsive eaters, meanwhile, reveal disturbances in brain reward circuits similar to those experienced by drug abusers.

Twenty-eight scientific studies and papers on food addiction have been published this year, according to a National Library of Medicine database. As the evidence expands, the science of addiction could become a game changer for the $1 trillion food and beverage industries.

If fatty foods and snacks and drinks sweetened with sugar and high fructose corn syrup are proven to be addictive, food companies may face the most drawn-out consumer safety battle since the anti-smoking movement took on the tobacco industry a generation ago.

DARPA Wants to Master the Neuroscience of Narrative

October 19, 2011 / Klint Finley

Once scientists have perfected the science of how stories affect our neurochemistry, they will develop tools to “detect narrative influence.” These tools will enable “prevention of negative behavioral outcomes … and generation of positive behavioral outcomes, such as building trust.” In other words, the tools will be used to detect who’s been controlled by subversive ideologies, better allowing the military to drown out that message and win people onto their side.

Danger Room: Darpa Wants to Master the Science of Propaganda

A couple years ago I would have dismissed this, but data scientists are getting closer to being able to pull this sort of thing off. I’d still say this is years off, but it’s edging closer to the realm of possibility.

Look, for instance, at how semantic analysis is affecting the legal profession and how many high-end, professional jobs are being replaced by robots.

Reverse Placebo: People Wrongly Diagnosed with Alzheimer’s Go Senile

August 30, 2011 / Klint Finley

Psychologists in the Netherlands have documented the case of a 58-year-old woman who was misdiagnosed with Alzheimer’s Disease. Her condition deteriorated to the point where she became permanently confused, and at one point suicidal — before another doctor realized the diagnosis was incorrect.

What happens to people who are wrongly diagnosed with having cognitive difficulties? It turns out that even if your brain is perfectly healthy, you’ll start having more problems with concentration.

The Neuroscience of Depression – And What to Do About It

July 20, 2011 / Klint Finley

Meditation

Math for Primates co-host Nick Horton wrote a personal post on how he manages his depression. Here’s a bit on the neuroscience of depression:

The Prefrontal cortex is the part of your brain that deals with (among other things) the regulation of mood states. If it is atrophied, then your ability to deal with these tasks gets downgraded. This becomes particularly problematic given that without the prefrontal cortex running at full speed, you can’t dampen the negative emotions generated by the Amygdala. The amygdala is that part of your brain that deals with Fight or Flight responses. It is your brains Fear Factory. To add fuel to the fire, in depressed people the amygdala tends to be overactive.

Think of the Amygdala and the prefrontal cortex as the brains Yin and Yang. You need both to be strong and healthy to have a strong healthy brain that is in balance. Depressed folk ain’t in balance. Generally, the prefrontal cortex is responsible for saying, “Hey, Amygdala, I got your message. We’re cool here. No need to freak out, dude!” But, when your brain is broke (like mine), you can be flooded with negative emotional responses that can result in despair and overwhelming helplessness.

The Iron Samurai: Managing Depression With Weightlifting? Or, How You Feel Is A Lie

I found this part interesting as well:

Depression is so debilitating precisely because of the trick your mind plays on you. It tricks you into believing that how you feel is valid. This sparks a downward spiral of sadness that makes life impossible. The more you play into its tricks, the harder it gets to drag yourself out of it.

It gave me an idea. People of above average intelligent are known to be prone to depression, right? Could it be because smart people are better at finding reasons to be depressed, locking themselves into this downward spiral? Could people of average or less intelligence be better at talking themselves out of being depressed? I’m not sure how to test this hypothesis.

What’s Next for Cognitive Training Games?

June 26, 2011 / Klint Finley

brain

Most of the cognitive training games of 2011 resemble the simple games you can play online for free or apps designed for smartphones. However, in ten years, we can expect many of the big developers, following Nintendo’s lead, to introduce critical gaming elements. Envision games featuring improved graphics, compelling gameplay, and engaging storylines that compel players to train their brains often and in a variety of ways. Imagine a role-playing game (RPG) in which your character’s level and progress are determined in part by your performance on a variety of cognitive training tasks, and the selection of tasks are dependent on the class chosen by the player, and thus tailored made for each individual user. Much in the same way that RPG style games will foster unique training experiences, cognitive training games in general will become tailored to individual interests, focusing on training specific cognitive mechanisms, rather than providing a general training regimen that the user may not be looking for. […]

Non-Conscious Defenses- Starting all the way back in the 1950’s, firms have sought to understand human psychology in order to capitalize on our biases and tendencies through influencing us on the sub-conscious level. In the past couple decades however, research into non-conscious processing and subliminal priming have begun to unravel the fascinating ways that people develop preferences for products and how they estimate value. Companies have been following this research closely and already implement their findings into many forms of media: magazines, movies and even presidential election commercials (5). Expect that training games will begin to offer cognitive defenses against advertising seeking to influence us on the sub conscious level.

The Future of Brain Workouts

N-Back Training Exercise Still Holding Up in Tests

Above: the Soak Your Head Dual N-Back Application

I’ve covered research on how most brain training exercises don’t actually hold-up in tests. The good news is that dual n-back training, also covered here previously, is continuing to hold up in tests:

Jonides, who is the Daniel J. Weintraub Collegiate Professor of Psychology and Neuroscience, collaborated with colleagues at U-M, the University of Bern and the University of Tapei on a series of studies with more than 200 young adults and children, demonstrating the effects of various kinds of n-back mental training exercises. The research was supported by the National Science Foundation and by the Office of Naval Research.

According to Jonides, the n-back task taps into a crucial brain function known as working memory—the ability to maintain information in an active, easily retrieved state, especially under conditions of distraction or interference. Working memory goes beyond mere storage to include processing information.

Soak Your Head offers a free Web-based n-back training program, but it requires Microsoft Silverlight. You can find a list of other applications here.

Another way to boost your mental capabilities? Play first person shooters. This NPR story provides an overview of the research. You can also find a research paper that looks at multiple studies here (PDF).

The best way to stave off cognitive decline, however, may be to spend time socializing with friends.

Brand Fanaticism Lights Up Same Part of the Brain as Religion

May 31, 2011 / Klint Finley

Glycon

Curt Hopkins compares the discovery that a company’s logo lights up the same brain regions in fans of that company that religious iconographic lights up in followers of the religion.

Anyway, the public (well, at least the free, male, moneyed public) that took such a hands-on role in shaping the policy of the Republic was displaced by an Imperial government that consolidated power in one man, whose will was carried out by a bureaucracy. When that happened, the formerly most influential elements of the society turned away from public life to “mystery religions”: Mithraism, the worship of Isis and of course Christianity.

In the same way, it feels that we’ve lost something in turn. I’m not sure what it is – religious faith, political will, tribal affiliation? – but I can feel it. With the loss of that thing, people have turned to brands, particularly to tech brands, with their promise of connection, amplification, justification, belonging. The promise of salvation and relevance.
