“Information in the Penumbra of Our Awareness” May Be Accessible

(p. C2) Here today, gone in a millisecond. At least that’s how we used to think about short-term, or working, memory. But a study just published in the journal Science tells a different story. A recent idea or word that you’re trying to recall has not, in fact, gone AWOL, as we previously thought. According to new brain-decoding techniques, it’s just sleeping.
“Earlier experiments show that a neural representation of a word disappeared,” said the study’s lead author, Brad Postle, a professor of psychology and psychiatry at the University of Wisconsin-Madison. But by using a trio of cutting-edge techniques, Dr. Postle and his team have revealed just where the neural trace of that word is held until it can be cued up again.
. . .
To confirm that the memory still existed even while a person was not thinking about it, the scientists used another recent technique, transcranial magnetic stimulation, or TMS. They positioned a wand over a participant’s scalp and delivered a harmless magnetic pulse to the brain areas that held the images. The pulse made the distinctive neural signature of those fleeting memories visible to the scientists and triggered their recall in the students.
Dr. Postle compared working memory to paper inscribed with invisible ink. Words written in lemon juice are initially imperceptible, but by passing a hot cup of coffee over the paper, “you can see the part of the message that was heated up…. Our TMS is like the coffee cup.” In this way the team activated a memory that was not only temporary but below the student’s level of consciousness.
Using Dr. Postle’s new trifecta of brain-imaging and brain-stimulation techniques to reactivate forgotten memories has enticing–though still remote–therapeutic possibilities. It is neuroscience’s most faithful reading yet of the real-time content of our thoughts–about as close as we have ever come to mind-reading.
“Our study suggests that there’s information in the penumbra of our awareness. We are not aware that it’s there, but it’s potentially accessible,” said Dr. Postle.

Video Gamers Become “More Optimistic, Creative, Courageous and Determined”

(p. 10) The principles of game design, McGonigal argues, can be used to turn not only leisure into productivity, but also sickness into health. By reframing recuperative tasks such as going for a walk, reconnecting with a friend or writing a short story as gamelike quests, healing can be systematized. Moreover, when you begin to tackle these life quests (McGonigal provides nearly 100 examples) you will, she writes, enter a “gameful” state, becoming more optimistic, creative, courageous and determined. By applying the psychological attributes that games unlock to real-world scenarios, we become like Mario as he guzzles a power-up and transforms into Super Mario.
McGonigal’s promises come thick and early, propped up by the results of two clinical studies. The 30-day program contained in the book will, she writes, “significantly” reduce symptoms of depression and anxiety and decrease suffering. It will increase optimism, make you “more satisfied” and even lead, incredibly, to a life “free of regret.” McGonigal claims that every day for more than five years she has heard from someone telling her that the program changed his or her life.

Intellectuals Embrace Despair

(p. A23) Public conversation is dominated by people’s ahistorical insistence that this country is sliding toward decline. As Arthur Herman writes in his book “The Idea of Decline in Western History,” “The sowing of despair and self-doubt has become so pervasive that we accept it as a normal intellectual stance — even when it is directly contradicted by our own reality.”

Do Manic Spells Help or Hurt Entrepreneurial Boldness?

(p. C1) In an author’s note, Mr. Kidder explains that “A Truck Full of Money” is a kind of sequel to “The Soul of a New Machine” (1981), his Pulitzer Prize-winner about the race to build a next-generation minicomputer. Fair enough: The writer is returning to his roots.
But a book about a software guy and software culture in 2016 isn’t nearly as novel as a book about hardware guys and hardware culture in 1981, and Mr. Kidder is not in the same command of his material.
. . .
(p. C4) There is, however, an element of Mr. English’s story that’s quite striking, one that makes “A Truck Full of Money” feel very much like a Tracy Kidder book.
In his 20s, Mr. English was told he had bipolar disorder. For a long time, he kept his diagnosis a secret. But today, he is wonderfully open and courageous about it.
Many of Mr. Kidder’s subjects are coiled with enough energy to launch a missile, of course, but Mr. English has a psychiatric diagnosis to go with it. The questions Mr. Kidder raises — Are Mr. English’s manic spells responsible for his entrepreneurial boldness? Or does he succeed in spite of them? — are well worth probing, and Mr. Kidder’s portrayal of living with manic depression is as nuanced and intimate as a reader might ever expect to get. On a good day, Mr. English’s mind is gaily swarming with bumblebees. On a bad one, though, he’s “Gulliver imprisoned by the tiny Lilliputians, laid out on his back, tied to the ground with a web of tiny ropes.”
Many of the features of Mr. English’s biography fit a familiar pattern. He was a low-achieving student with a high-watt intelligence. He discovered computer programming in middle school and was instantly smitten; today, he thinks fluently in layers of code — “each hanging from the one above, like a Calder mobile” — and his brain is a regular popcorn maker of ideas.
. . .
When he’s “on fire” (his term), he grows irritable with the slow dial-up connection of other people’s brains. He exaggerates. He slurs his words. His ideas range from extremely creative to flat-out wackadoo.
. . .
Over the years, Mr. English has tried a Lazy Susan of medications to subdue his highs and avert his lows. Many left him feeling listless and without affect. Being bipolar meant constantly weighing the merits of instability versus a denatured, drained sense of self.

Rat Ticklers Find Ticklishness Has Deep Evolutionary Roots

(p. A12) As Michael Brecht and Shimpei Ishiyama of the Bernstein Center for Computational Neuroscience in Berlin point out in their report, tickling raises many questions. We don’t know why it evolved, what purpose it might serve and why only certain body parts are ticklish. And what about that disappointing and confounding truth that all children and scientists must grapple with: You can’t tickle yourself.
The researchers were also inspired by earlier studies. ” ‘Laughing’ Rats and the Evolutionary Antecedents of Human Joy?” published in 2003 in Physiology & Behavior, reported that rats would emit ultrasonic calls when tickled. Ultrasound is too high for humans to pick up.
. . .
The scientists found that tickling and play, which involved chasing a researcher’s hand, both caused the same ultrasonic calls and the same brain cells to be active. The scientists also stimulated those cells electrically, without any tickling or play, and got the same calls.
And they found that you can’t tickle rats when they are not in a good mood, something that is also true of people.
. . .
And the similarity of tickling in rats and humans is, Dr. Brecht said, “amazing.” They even have similar areas that are susceptible for unknown reasons, including the soles of their hind feet, but not of their forepaws.
That similarity suggests that tickling is evolutionarily very ancient, going back to the roots of touch as a way to form social bonds in the ancestors of rats and humans.
“Maybe,” Dr. Brecht speculated, “ticklishness is a trick of the brain to make animals or humans play or interact in a fun way.”

Is Asperger’s a Disease to Be Cured or “a Way of Being” to Be Celebrated?

(p. C1) . . . until eight years ago, Mr. Robison, who wrote the 2007 memoir “Look Me in the Eye,” a touchstone in the literature of Asperger’s syndrome, had never experienced the most obvious aspect of music that neurotypical people do: its simple emotional power.
That all changed, Mr. Robison explains in “Switched On: A Memoir of Brain Change and Emotional Awakening,” when he participated in a pioneering Asperger’s study at Beth Israel Deaconess Medical Center in Boston in 2008. Using transcranial magnetic stimulation, or TMS, doctors hoped to activate neurological pathways in his brain that would deepen his emotional intelligence.
Driving home after his first session, Mr. Robison cranked up a song he’d heard countless times before. Before he knew it, tears were streaming down his face.
. . .
(p. C6) “Switched On” is subversive in more ways than one. In this age of heightened sensitivity to neurodiversity, one of the most uncomfortable notions you can raise about Asperger’s is that it can cruelly obscure the most basic elements of personality. The very idea is offensive and wounding to many people, because it frames a difference as a deficit; to wistfully suggest that a person with Asperger’s might be someone else without Asperger’s is to denature them completely, to wish their core identities into oblivion.
“Asperger’s is not a disease,” Mr. Robison wrote in “Look Me in the Eye.” “It’s a way of being. There is no cure, nor is there a need for one.”
In “Switched On,” Mr. Robison, 58, retains his Asperger’s pride. Part of him even fears he’ll lose his special gifts, on the (beguiling, I thought) theory that “perhaps the area that recognizes emotions in people was recognizing traits of machinery for me.”
But he is also torn. He did not come of age when “neurodiversity” was part of our vocabulary of difference. He did not come of age when “Asperger’s” was part of our vocabulary at all. He received his autism diagnosis at 40, and he has many memories of being bullied, losing jobs and mishandling social situations because of his inability to read others.
. . .
Mr. Robison still believes autism is not a disease. “But I also believed in being the best I could be,” he writes, “particularly by addressing the social blindness that had caused me the most pain throughout my life.”
But if the effects of Asperger’s can be mitigated, what consequences will that have? And what does it mean for the future of the neurodiversity movement?

When People’s Lives Stagnate They “Often Become Angry, Resentful”

(p. 3) Benjamin M. Friedman of Harvard University, in his book “The Moral Consequences of Economic Growth” (Knopf, 2005), said that at a deep level people make judgments about the economic progress that they see in their own lifetimes, and in comparison with the progress made by the previous generation, especially their own parents. Few people study economic growth statistics. But nearly everyone knows what they are being paid. If they realize that they are doing less well than their forebears, they become anxious. And if they can’t see themselves and others in their cohort as progressing over a lifetime, their social interactions often become angry, resentful and even conspiratorial.

Those Who See, and Fill, Big Unmet Needs Are Often “Weirdos”

(p. A11) . . . “A Truck Full of Money” provides a portrait of a strange, troubled man who happens to be one of the smartest minds in the Route 128 tech corridor.
. . .
The book is being marketed as inspirational, but I found it to be the opposite. No one could read it and become Paul English, or want to. Most tech startups think too small, but the few people with the vision to identify big unmet needs seem to be, for whatever reason, weirdos. The split-second fare comparison that Kayak did is something no human being could do–it requires super-computing–and it has an enormous value, since 8% of the U.S. economy is travel. But once you’ve solved a problem like that, what do you do next?
Paul English hasn’t figured that out, so this book sort of peters out–he may do his once-in-a-lifetime charity project, or he may follow through on Blade–and he has retreated back into the familiar, running a company called Lola that is sort of the opposite of Kayak: It gives you live access to travel concierges. But how could Mr. Kidder’s ending be anything but inconclusive? Mr. English is just 53. Undoubtedly he has another billion-dollar idea nestled in that overactive brainpan, but his investors have to make a leap of faith–that they’ve bet on the right weirdo. God bless these genius geeks, who make our economy leaner by constantly finding more efficient ways to do old things. And God bless the pharmaceutical industry, which protects and preserves them.​

Uber Drivers Learn to Work Optimal Hours

(p. B1) For nearly 20 years, economists have been debating how cabdrivers decide when to call it a day. This may seem like a trivial question, but it is one that cuts to the heart of whether humans are fundamentally rational — in this case, whether they earn their incomes efficiently — as the discipline has traditionally assumed.
In one camp is a group of so-called behavioral economists who have found evidence that many taxi drivers work longer hours on days when business is slow and shorter hours when business is brisk — the opposite of what economic rationality, to say nothing of common sense, would seem to dictate.
In another camp is a group of more orthodox economists who argue that this perverse habit is largely an illusion in the eyes of certain researchers. Once you consult more precise numbers, they argue, you find that drivers typically work longer hours when it is in their financial interest to do so.
. . .
So who is right? That’s where Uber comes in. When one of the company’s researchers, using its supremely detailed data on drivers’ work time and rides, waded into the debate with a paper this year, the results were intriguing.
Over all, there was little evidence that drivers were driving less when they could make more per hour than usual. But that was not true for a large portion of new drivers. Many of these drivers appeared to have an income goal in mind and stopped when they were near it, causing them to knock off sooner when their hourly wage was high and to work longer when their wage was low.
. . .
“A substantial, although not most, frac-(p. B5)tion of partners do in fact come into the market with income targeting behavior,” the paper’s author, Michael Sheldon, an Uber data scientist, wrote. The behavior is then “rather quickly learned away in favor of more optimal decision making.”
In effect, Mr. Sheldon was saying, the generally rational beings that most economists presume to exist are made, not born — at least as far as their Uber driving is concerned.
. . .
As for Mr. Sheldon, the Uber paper’s author, he attributed his finding to the adventurous nature of many Uber drivers, who were open to running headlong into unfamiliar territory. It’s the sheer unfamiliarity of the Uber driving experience, he speculated, that may explain the initial bout of economically irrational behavior.
Mr. Sheldon was less open to the idea that people who did not depend on Uber for their livelihood helped account for his finding. So far as Uber can tell from other research, he said, those who drive irregularly respond more to fare increases than more regular drivers, at any level of earnings.
