HOW NEUROSCIENCE SUPPORTS VIRGINIA WOOLF.

Sunday, November 30th, 2008

HOW NEUROSCIENCE SUPPORTS VIRGINIA WOOLF. Jonah Lehrer explains how neuroscience supports Virginia Woolf’s view that the mind is, as her character Mrs. Ramsay says, “always ‘merging and flowing and creating.’” Experiments show that short-term memory can hold an experience for about ten seconds. And the neurons which are activated are distributed all over the brain. Lehrer also explains how neuroscience supports Woolf’s view that the self emerges from paying attention. “Whenever we pay attention to a specific stimulus—like a pear on a dinner table—we increase the sensitivity of our own neurons.” When Mrs. Ramsay focuses on the fruit, “she is literally altering her own cells.” That which directs the attention can be considered the self.

THE SELF EMERGES BY PAYING ATTENTION.

THE SELF EMERGES BY PAYING ATTENTION. Jonah Lehrer illustrates Virginia Woolf’s view of the mind with a passage from TO THE LIGHTHOUSE. Mrs. Ramsay has stopped paying attention to the dinner table conversation, which is about mathematics. Her eyes drift over a bowl of fruit on the table. “With a ‘sudden exhilaration,’ her mind becomes ‘like a light….piercing through the flowing, the fleeting, the spectral.’” The book follows her glance as she decides she does not want a pear. Lehrer concludes that: “Woolf realized that the self emerges via the act of attention [emphasis in Lehrer].” The self is what selects from the stream of impressions that the mind receives.

COMPETING SELVES OR SIMPLY A MYRIAD OF IMPRESSSIONS?

Saturday, November 29th, 2008

COMPETING SELVES OR SIMPLY A MYRIAD OF IMPRESSIONS? I posted recently on the research of psychologists who view the human mind as made up of competing selves. Jonah Lehrer writes in PROUST WAS A NEUROSCIENTIST that Virginia Woolf‘s view was that “we emerge from our own fleeting interpretations of the world…. [W]e…invent…a perceiver for our perception. The self….is the story we tell ourselves about our experiences.” Lehrer says that for Woolf, “the self is an illusion [emphasis in Lehrer].” Note that Woolf is dealing with a different kind of mental activity than the psychologists who focus on how we make decisions. Woolf is dealing with how we experience the world and how we experience the feeling of being ourselves.

MODERNISM AND THE MIND—AND A BOOK RECOMMENDATON.

Saturday, November 29th, 2008

MODERNISM AND THE MIND—AND A BOOK RECOMMENDATION. Almost two years ago, I posted here on how Proust seemed to have anticipated some of the findings of behavioral psychologists described in Daniel Gilbert’s STUMBLING ON HAPPINESS. I then found out and posted that Jonah Lehrer had a book coming out entitled PROUST WAS A NEUROSCIENTIST. The book is very rewarding. Lehrer has lots of insights from neuroscience on writers and artists such as Proust, Whitman, Cezanne, George Eliot and Virginia Woolf. As an example, Lehrer writes that: “this vision of a mercurial mind, a self divided against itself, was one of the central tenets of modernism.” Lehrer illustrates this proposition with citations to Nietszche, Rimbaud, William James, Freud and T.S. Eliot. And then he connects it all to neuroscience.

TESTING THE BROKEN WINDOW THEORY.

Friday, November 28th, 2008

TESTING THE BROKEN WINDOW THEORY. This article in the Economist describes experiments at the University of Groningen in the Netherlands which tested the Broken Windows Theory. The most striking experiment for me (and for the Economist) was “the one that showed a doubling in the number of people who were prepared to steal in a condition of disorder.” In a condition of order, 13% of passersby stole a 5 euro note which could be seen sticking out of a mailbox; in a condition of disorder (surrounding litter, graffiti on mailbox), 27% stole it. I have moved my subjective belief in the Broken Window Theory up to 75%

CHANGING MY MIND: BROKEN WINDOWS.

Friday, November 28th, 2008

CHANGING MY MIND: BROKEN WINDOWS. For years, when I lived in New York, I was impatient with efforts by the city to stop graffiti. It seemed to me self-evident that police efforts should give priority to major crimes. There were lots of major crimes. James Q. Wilson and others put forth the theory in the early eighties that crime is frequent in neighborhoods with disorder and lots of petty violations of the law. I was skeptical. When Rudy Giuliani was elected mayor of New York and made clear that he was going to enforce strictly laws against petty crimes –to crack down on “squeegee men”—I considered that this would be a good test of the Broken Window Theory. Low and behold, there was a remarkable drop in major crimes. My subjective belief in the Broken Window Theory had been about 5%. After what happened in New York, I would have put my subjective belief in the Broken Window Theory at maybe 70%. The theory is still highly controversial. This wikipedia article describes the alternative explanations that have been given for the drop in crime in New York.

THANKSGIVING 2008.

THANKSGIVING 2008. In one of the first posts on this blog, I gave “thanks for all that the Americans who have gone before us have given us” and I listed the names of some of those heroes. As you can read in the comments, there was a happy sequel. Thanksgiving is, I think, our most important family holiday. Our family sends best wishes to the families of all who read this.

THANKS TO THOSE WHO WENT BEFORE.

Thursday, November 27th, 2008

THANKS TO THOSE WHO WENT BEFORE. When Annalisa and Nick first saw LES MISERABLES as children, they had the same reaction to the two young leads, Cosette and Marius. They thought that Cosette and Marius were bland and undeserving of the extraordinary efforts that the previous generation (Jean Valjean and Fantine) made on their behalf. When I watch LES MIS, I respond emotionally to what Annalisa and Nick responded to. I think of all the challenges that the generations that went before us overcame so that we can be here today. And I am flooded with gratitude. Thanks to all of them.

FINDING A PATTERN IN RANDOMNESS.

Wednesday, November 26th, 2008

FINDING A PATTERN IN RANDOMNESS. I posted here on the Random Walk Hypothesis in response to Annalisa’s comment that stock prices seem to move randomly. Humans see patterns even when there is no pattern and look for causation where none exists. They look for patterns in the movements of stock prices and commodity prices. No matter how large the price movement.there is always an explanation in the newspapers the next day. Jonah Lehrer describes an experiment in which rats were presented with a choice. On average, going to the left gave the rat a reward 60% of the time, but whether there was a reward was randomly distributed. The rats soon learned to go left all of the time, and were rewarded 60% of the time. Yale undergraduates were given the same kind of choice. They kept trying to find a pattern and wound up being rewarded only 52% of the time.

THE WILL POWER OF A TRUE STOIC.

Tuesday, November 25th, 2008

THE WILL POWER OF A TRUE STOIC. The Sidestep blog posted here on a good example of the will power of a Stoic for whom an exception to a principle is unthinkable. The example comes from A MAN IN FULL by Tom Wolfe. Wolfe’s character says, “To a Stoic there are no dilemmas. They don’t exist.” Wolfe’s character then tells a story about a Stoic named Aggripinus. A frightened historian rushes in to see Aggripinus and says:
“The most terrible thing has happened. I’ve been summoned to appear in one of Nero’s plays. If I do it, I’ll be humiliated before everybody in Rome that I care about. If I don’t I’ll be killed.”
“I’ve received the same summons,” says Agrippinus.
“My God,” says the historian, “you, too! What do we do?”
“You go ahead and act in the play,” says Agrippinus. “I’m not going to.”
“Why me and not you?” says the historian.
“Because you’ve considered it.”
