Training the Emotional Brain : An Interview with Richard J. Davidson : Sam Harris - 0 views
-
From quite early on in my career, there were two critical observations that came to form the core of my subsequent life’s work. The first observation is that the most salient characteristic of emotion in people is the fact that each person responds differently to life’s slings and arrows. Each of us is unique in our emotional make-up and this individuality determines why some people are resilient and others vulnerable, why some have high levels of well-being despite objective adversity while others decompensate rapidly in the response to the slightest setback.
-
the great fortune I had early in my career to be around some remarkable people. They were remarkable not because of their academic or professional achievements, but rather because of their demeanor, really because of their emotional style. These were extremely kind and generous people. They were very attentive, and when I was in their presence I felt as if I was the sole and complete focus of all of their attention. They were people that I found myself wishing to be around more. And I learned that one thing all of these people had in common was a regular practice of meditation. And I asked them if they were like that all of their lives and they assured me they were not, but rather that these qualities had been nurtured and cultivated by their meditative practices.
-
It wasn’t until many years later that I encountered neuroplasticity and recognized that the mechanisms of neuroplasticity were an organizing framework for understanding how emotional styles could be transformed. While they were quite stable over time in most adults, they could still be changed through systematic practice of specific mental exercises. In a very real and concrete sense, we could change our brains by transforming our minds. And there was no realm more important for that to occur than emotion. For it is so that our emotional styles play an incredibly important role in determining who will be vulnerable to psychopathology

primates have a remarkable ability to detect snakes, even in a chaotic visual environment.

first evidence of snake-selective neurons in the primate brain that I’m aware of,
-
recorded pulvinar neuronal activity via electrodes implanted into the brains of two adult macaques—one male, one female—as they were shown images of monkey faces, monkey hands, geometric shapes, and snakes. The brains of both monkeys—which were raised at a national monkey farm in Amami Island, Japan, and had no known encounters with snakes before the experiment—showed preferential activity of neurons in the medial and dorsolateral pulvinar to images of snakes, as compared with the other stimuli. Further, snakes elicited the fastest and strongest responses from these neurons.

Why Police Lineups Will Never Be Perfect - The Atlantic - 1 views
-
Eyewitness testimony is hugely influential in criminal cases. And yet, brain research has shown again and again that human memory is unreliable: Every time a memory is recalled it becomes vulnerable to change. Confirming feedback—such as a detective telling a witness she “did great”—seems to distort memories, making them feel more accurate with each recollection. Since the start of the Innocence Project 318 cases have been overturned thanks to DNA testing. Eyewitness mistakes played a part in nearly three-quarters of them.
-
psychology researchers have been searching for ways to make eyewitness identifications more reliable. Many studies have shown, for example, the value of “double-blind” lineups, meaning that neither the cop administering the lineup nor the witness knows which of the photos, if any, is the suspect.
-
160 page report offers many concrete suggestions for carrying out eyewitness identifications. For example, the Academy recommends using double-blind lineups and standardized witness instructions, and training law enforcement officials on the fallibility of eyewitness memory.

The Science of Why We Don't Believe Science | Mother Jones - 2 views
-
an array of new discoveries in psychology and neuroscience has further demonstrated how our preexisting beliefs, far more than any new facts, can skew our thoughts and even color what we consider our most dispassionate and logical conclusions. This tendency toward so-called "motivated reasoning" helps explain why we find groups so polarized over matters where the evidence is so unequivocal: climate change, vaccines, "death panels," the birthplace and religion of the president (PDF), and much else. It would seem that expecting people to be convinced by the facts flies in the face of, you know, the facts.
-
The theory of motivated reasoning builds on a key insight of modern neuroscience (PDF): Reasoning is actually suffused with emotion (or what researchers often call "affect"). Not only are the two inseparable, but our positive or negative feelings about people, things, and ideas arise much more rapidly than our conscious thoughts, in a matter of milliseconds—fast enough to detect with an EEG device, but long before we're aware of it. That shouldn't be surprising: Evolution required us to react very quickly to stimuli in our environment. It's a "basic human survival skill," explains political scientist Arthur Lupia of the University of Michigan. We push threatening information away; we pull friendly information close. We apply fight-or-flight reflexes not only to predators, but to data itself.
-
reasoning comes later, works slower—and even then, it doesn't take place in an emotional vacuum. Rather, our quick-fire emotions can set us on a course of thinking that's highly biased, especially on topics we care a great deal about.

All Can Be Lost: The Risk of Putting Our Knowledge in the Hands of Machines - Nicholas ... - 0 views

We rely on computers to fly our planes, find our cancers, design our buildings, audit our businesses. That's all well and good. But what happens when the computer fails?

On the evening of February 12, 2009, a Continental Connection commuter flight made its way through blustery weather between Newark, New Jersey, and Buffalo, New York.
-
The Q400 was well into its approach to the Buffalo airport, its landing gear down, its wing flaps out, when the pilot’s control yoke began to shudder noisily, a signal that the plane was losing lift and risked going into an aerodynamic stall. The autopilot disconnected, and the captain took over the controls. He reacted quickly, but he did precisely the wrong thing: he jerked back on the yoke, lifting the plane’s nose and reducing its airspeed, instead of pushing the yoke forward to gain velocity.

WHICH IS THE BEST LANGUAGE TO LEARN? | More Intelligent Life - 2 views
-
For language lovers, the facts are grim: Anglophones simply aren’t learning them any more. In Britain, despite four decades in the European Union, the number of A-levels taken in French and German has fallen by half in the past 20 years, while what was a growing trend of Spanish-learning has stalled. In America, the numbers are equally sorry.
-
compelling reasons remain for learning other languages.
-
First of all, learning any foreign language helps you understand all language better—many Anglophones first encounter the words “past participle” not in an English class, but in French. Second, there is the cultural broadening. Literature is always best read in the original. Poetry and lyrics suffer particularly badly in translation. And learning another tongue helps the student grasp another way of thinking.

Polling's Secrecy Problem - NYTimes.com - 0 views
-
In the polling world, no survey firm releases its microdata in a timely manner. When pollsters release it at all — usually months after publication, to an archive that requires a paid subscription for access — they seldom provide the detailed methodological explanations necessary to replicate the survey results.
-
Critics have raised charges of full-scale fabrication, like that alleged in the LaCour study, about a handful of pollsters in recent years, and such a wholly fraudulent poll might well be able to evade detection.
-
But a bigger problem is that pollsters may be using questionable means to ensure that their results end up in a certain place. Any poll is required to make judgments about exactly how to weight the sample or decide who is likely to vote. But such choices can swing the results by several percentage points, and these decisions can be made with the results in mind.

The Dark Side of Oxytocin, the Hormone of Love - Ethnocentrism - NYTimes.com - 0 views
-
As oxytocin comes into sharper focus, its social radius of action turns out to have definite limits. The love and trust it promotes are not toward the world in general, just toward a person’s in-group. Oxytocin turns out to be the hormone of the clan, not of universal brotherhood. Psychologists trying to specify its role have now concluded it is the agent of ethnocentrism.
-
In Dr. De Dreu’s experiments, the five people who might be saved were nameless, but the sacrificial victim had either a Dutch or a Muslim name. Subjects who had taken oxytocin were far more likely to sacrifice the Muhammads than the Maartens.
-
Dr. De Dreu plans to investigate whether oxytocin mediates other social behaviors that evolutionary psychologists think evolved in early human groups. Besides loyalty to one’s own group, there would also have been survival advantages in rewarding cooperation and punishing deviants. Oxytocin, if it underlies these behaviors too, would perhaps have helped ancient populations set norms of behavior.
