How Facebook Is Throwing Our Brains Into Overdrive - Pacific Standard - 0 views

facebook neuroscience manipulation

shared by Steve Bosserman on 04 May 18 - No Cached
  • The human brain has always loved the dopamine rush of notifications, in any form; recent research indicates the unpredictable but ubiquitous updates of Gmail or Twitter carry the same neurological effect as rocking a slot machine. While Internet use is "not addictive in the same way as pharmacological substances are," as cognitive scientist Tom Stafford noted in 2013, we continually chase those unpredictable payoffs on Facebook and Instagram in ways that tend to mirror gambling or sex addictions, even if "Internet addiction" writ large currently holds an ambiguous position in the Diagnostic and Statistical Manual of Mental Disorders.
  • For products whose fundamental business proposition is harnessing attention, building those so-called "compulsion loops" isn't an accident of technology—it's the whole point. Indeed, observers have argued since Parker's "human psychology" flub last year that Facebook has not just meticulously measured, but fundamentally altered human behavior, and nascent technology ventures emboldened by Facebook's world-changing success have sought to translate the behavioral tricks that psychologist B.F. Skinner applied to the gambling kiosk to every mobile app under the sun. "When a gambler feels favored by luck, dopamine is released," Natasha Schüll, author of Addiction by Design: Machine Gambling in Las Vegas, told the Guardian in March. All Facebook managed to do was find a way to miniaturize the captivating logic of the slot machine—with no cost to the user but their time and attention.
  • While the human brain is tremendously plastic, that doesn't mean Facebook is savagely rewiring the human brain. Indeed, the Facebook users in the Cal State–Fullerton study "showed greater activation of their amygdala and striatum, brain regions that are involved in impulsive behavior," as Live Science's Tia Ghose reported at the time. Ghose continued: "But unlike in the brains of cocaine addicts, for instance, the Facebook users showed no quieting of the brain systems responsible for inhibition in the prefrontal cortex." Facebook isn't fundamentally rewiring the structure of the human brain, but its ubiquity has the same relative effect by kicking our rewards centers into overdrive.

    Natural hazard events, such as storms, floods, and wildfires, entail huge and growing costs all over the world, but they can also be occasions for countries to implement risk-reducing changes. There is no research consensus on whether natural hazard events lead to policy modifications or, instead, contribute to stability and preservation of existing solutions. Knowledge in this area to date has been based on individual case studies, and global trends have not been studied.

How Neuroscience Can Help Us Treat Trafficked Youth - Pacific Standard - 0 views

neuroscience youth "human trafficking"

shared by Steve Bosserman on 04 May 18 - No Cached
  • A common misconception is that these youths are choosing to engage in the commercial sex trade. But as recent advances in neuroimaging techniques help scientists unravel the myriad ways that trauma affects the brain, emerging evidence suggests that brain changes resulting from trauma could make young people more vulnerable to exploiters and less receptive to people trying to help. Rather than making a conscious decision to rebel, these kids are simply doing their best to survive, using the adaptive strategies that their brains developed in response to a perilous world.
  • Though the human brain is adaptable throughout life, adaptability is greatest during childhood, as the developing brain responds to the surrounding environment. Survival is the brain's top priority. Young people growing up in dangerous environments will develop brains that are highly responsive to threat cues. In particular, recent studies show that children who have experienced trauma exhibit drastic changes in their amygdala, an area of the brain wired to identify signs of danger.
  • Besides the amygdala, another brain region affected by trauma is the hippocampus, an area involved with contextual learning and memory. The hippocampus takes context into account, so that a person can appropriately respond to the same cues in different situations. For instance, most people would respond differently to hearing gunfire in a shooting range than they would to hearing gunfire in an airport.

  • McLaughlin's research shows that youth who have experienced trauma have a smaller hippocampus than those who haven't, and are less able to take context into account when they detect a threat cue. When McLaughlin presented images of faces embedded in real-world scenes to kids, those with a history of trauma exhibited less activity in their hippocampus while viewing angry facial expressions. And when given a memory test afterward, they were less able to remember scenes in which they'd identified people displaying anger.
  • Because the brain remains malleable throughout life, it's never too late to mitigate the effects of trauma, McLaughlin says. There are a variety of evidence-based treatments that have proven effective in alleviating the mental-health consequences of trauma. For example, the technique of cognitive reappraisal, a cornerstone of Trauma-Focused Cognitive Behavioral Therapy, can help victims better regulate their emotions by changing the way they view a distressing situation. They can try to imagine that the situation is occurring far away from them, or that they are viewing the event from a removed perspective, as though watching a movie screen. When McLaughlin taught such techniques to young people in her lab, they were able to decrease their emotional reactivity as well as their amygdala response to negative stimuli.

work-life balance meaningful work

  • What he found was that—in the absence of a perpetually-growing economy—community and culture are key. He quotes, for example, the historian Juliet Schor’s view of working life in the Middle Ages: “The medieval calendar was filled with holidays …These were spent both in sober churchgoing and in feasting, drinking and merrymaking …All told, holiday leisure time in medieval England took up probably about one third of the year. And the English were apparently working harder than their neighbors. The ancien régime in France is reported to have guaranteed fifty-two Sundays, ninety rest days, and thirty-eight holidays. In Spain, travelers noted that holidays totaled five months per year.”
  • Reading this took me back to a childhood fed by TV programmes like the BBC’s Tomorrow’s World, which had informed me that by now robots would be doing all the menial work, leaving humans free to relax and enjoy an abundance of leisure time. So it came as a shock to realise that the good folk of the Middle Ages were enjoying far more of it than we are in our technologically-advanced society. What gives? Fleming explains, “In a competitive market economy a large amount of roughly-equally-shared leisure time – say, a three-day working week, or less – is hard to sustain, because any individuals who decide to instead work a full week can produce for a lower price (by working longer hours than the competition they can produce a greater quantity of goods and services, and thus earn the same wage by selling each one more cheaply). These more competitive people would then be fully employed, and would put the more leisurely out of business completely. This is what puts the grim into reality.”

climate change

  • Parallel to the IPCC process, scientific advances mean that models can now link individual weather events to climate change as the cause, said Friederike Otto, acting director of the Environmental Change institute at the University of Oxford in the UK. This is done through attribution science—much in the same way that smoking was linked to cancer decades ago—which is “very much in legal discussions at the moment”, said Otto. Attribution science has been a game changer in the past five years, added Yamin: in the case of an event such as flooding or a heat wave, for example, “you don’t talk about a vague sense of weather any more — you can link it to anthropogenic activities that are causing long-term global change”.

    "The above summary does not do justice to Martyanov's truly seminal book. I can only say that I consider this book as an absolutely indispensable "must read" for every person in the USA who loves his/her country and for every person who believes that wars, especially nuclear ones, must be avoided at all costs. Just like many others (I think of Paul Craig Roberts), Martyanov is warning us that "the day of reckoning is upon us" and that the risks of war are very real, even if for most of us such an event is also unthinkable. Those in the USA who consider themselves patriots should read this book with special attention, not only because it correctly identifies the main threat to the USA, but also because it explains in detail what circumstances have resulted in the current crisis. Waving (mostly Chinese made) US flags is simply not an option anymore, neither is looking away and pretending that none of this is real. Martynov's book will also be especially interesting to those in the US armed forces who are observing the tremendous decline of US military power from inside. Who better than a former Soviet officer could not only explain, but also understand the mechanisms which have made such a decline possible?"

sustainable agriculture capitalism

shared by Steve Bosserman on 29 Jan 19 - No Cached
  • One problem is the price of the produce. Many of us have had the experience of turning up at our local farmers' market, armed with tote bags, only to slink back to the supermarket after seeing the prices of the vegetables on offer. This is hardly the fault of the individual farmers. Still, as Pilgeram points out in a paper that she published in 2011, the costs involved with running such an operation mean that the benefits are inevitably affordable only to a small (generally white and middle-class) portion of society.
  • But it's a limited victory, Pilgeram writes in her most recent paper, published in November of 2018, and empowers only a certain class of women "while leaving [the capitalist] system basically entirely unaffected"—and which also risks gentrifying the towns to which these farmers move, further entrenching the country's class divide.
  • "The economic system that we have in place makes it impossible, really, to create a socially just food system. It's not possible under capitalism," Pilgeram says. Without a drastic change to this system, sustainable agriculture risks becoming an "esoteric side note" to conventional agriculture, she adds—or simply another way for those with money to live healthier lives than those without.

shared by Steve Bosserman on 15 May 18 - No Cached
  • But new research finds one factor that influences the rate at which our brains age is largely outside our control: our socioeconomic status.
  • "Engaging and resourceful environments associated with higher socioeconomic status may provide a buffer or delay against aging," the researchers write. "Inadequate health conditions associated with lower socioeconomic status environments (such as exposure to toxins and poorer nutrition), together with continual stress, may accelerate the aging process."
  • Using neuroimaging, the researchers evaluated participants' brains in two ways, measuring "functional network organization and cortical gray matter thickness." They found both measures demonstrated greater aging in people of lower socioeconomic status, even after accounting for demographic differences and personal health.

  • A 2014 study found African-Americans age more rapidly than whites, presumably due to the stress of dealing with racism.We've long been told that a mind is a terrible thing to waste. Perhaps we need to remember it's also a terrible thing for a mind to waste away.
