You are reading Futurismic. You find a post about how you imagine the events described in narratives…

406px-Kuniyoshi_Utagawa,_Woman_reading I mostly write novels in third person, although one of my YA novels (Andy Nebula: Interstellar Rock Star) was written in first. Now research has come along that examines how pronouns influence the way we imagine events being described in narratives (Via PhysOrg):

In these experiments, volunteers read sentences describing everyday actions. The statements were expressed in either first- (“I am…”), second- (“You are…”) or third-person (“He is…”). Volunteers then looked at pictures and had to indicate whether the images matched the sentences they had read. The pictures were presented in either an internal (i.e. as though the volunteer was performing the event him/herself) or external (i.e. as though the volunteer was observing the event) perspective.

The results, reported in Psychological Science, a journal of the Association for Psychological Science, indicate that we use different perspectives, depending on which pronouns are used. When the volunteers read statements that began, “You are…” they pictured the scene through their own eyes. However, when they read statements explicitly describing someone else (for example, sentences that began, “He is…”) then they tended to view the scene from an outsider’s perspective. Even more interesting was what the results revealed about first-person statements (sentences that began, “I am…”). The perspective used while imagining these actions depended on the amount of information provided – the volunteers who read only one first-person sentence viewed the scene from their point of view while the volunteers who read three first-person sentences saw the scene from an outsider’s perspective.

So if you really want someone to imagine they’re experiencing the events described in a story first-hand, you need to write in second person. Even with first-person fiction, your readers step outside your narrator’s point of view and imagine things as if they’re viewing it on TV.

Does this presage a vast upswelling of second-person fiction?

I hope not. ‘Cause the one thing the researchers haven’t explained is why second-person fiction is so intensely annoying. Plus it makes everything sound like a Choose Your Own Adventure book.

“You are reading a novel written entirely in second person. You try one paragraph, then a second. Then a third. You get fed up with the constant repetition of the word ‘you’. You swear at the author. You throw the book across the room…”

Reverse engineering the brain

thinkResearchers describe how it might one day be possible to simulate large parts of the human cortex on a computer, and how this could lead to functional human equivalent AI:

Software simulation of the human brain is just one half the solution. The other is to create a new chip design that will mimic the neuron and synaptic structure of the brain.

That’s where Kwabena Boahen, associate professor of bioengineering at Stanford University, hopes to help. Boahen, along with other Stanford professors, has been working on implementing neural architectures in silicon.

One of the main challenges to building this system in hardware, explains Boahen, is that each neuron connects to others through 8,000 synapses. It takes about 20 transistors to implement a synapse, so building the silicon equivalent of 220 trillion synapses is a tall order, indeed.

This is a different approach to more traditional AI research that has been going on for decades: instead of trying to write artificially intelligent computer programs using knowledge representation or commonsense knowledge representation now researchers are concentrating on reverse-engineering the only extant example of general intelligence we have.

Brain surgery, media, and serendipity

brainA North Carolina neurosurgeon had just about given up on the case of Brandon, a 19-year-old tumor patient, till a story on CNN.com led him to a new surgical tool that let him operate successfully.

Dr. Thomas Ellis, a senior neurosurgeon at Wake Forest University School of Medicine, had given the mother the bad news. But:

“As I do every night, I read CNN online and immediately saw on the front page that there was an article in the health section entitled, From military device to life-saving surgical tool. …”

Ellis got in touch with the manufacturer in Massachusetts, and 72 hours later the device was in his hands.

It was originally devised for the U.S. military, and rolled out for surgeries three months before Ellis read about it.

The tool allows surgeons to easily manipulate a CO2 laser and bend it to reach almost any tissue in the body, particularly in cases where scalpels may pose a danger.

Next day (Christmas Eve, no less):

“After only 30 minutes, it was clear this laser device, as simple to use as a scalpel, was successfully debulking the tumor.”

Ellis operated on Brandon for four hours and managed to remove the remaining 80 percent of the tumor by vaporizing it from the inside with the laser and then excising it.

“The boy was then extubated [removing the tube to his airway] after about 30 minutes and that same evening he was eating normally,” Wolf said.

Brandon has recovered his basic functions and is behaving normally.

Ellis says:

“I think it’s an amazing story because it’s yet another demonstration of how interconnected we’ve become in this world.

“You have a CNN reporter in London, who writes a story about a neurosurgeon in Chicago, who’s using a device that was invented in Massachusetts. That story is read by a different neurosurgeon in North Carolina, and all within 72 hours, we have the device in North Carolina.”

Investigating the science of fiction

brain scans A new brain-imaging study shows what parts of the brain are active as we read a narrative, suggesting that as readers we create vivid mental situations of what is described and activate the part of the brain we would use to process similar experiences in real life. (Via PhysOrg.)

The research was conducted at the Dynamic Cognition Laboratory at Washington University in St. Louis, Missouri (and the paper, published in Psychological Science, is online here). (CORRECTION: That link leads to an older study published in the same journal by the same authors a couple of years ago. It’s related research, but not the newest study, which won’t be posted in public for another month or so. – EW.)

(UPDATE: Well, that was quick. A pre-print version of the current study is now online here. – EW) 

Participants each read four stories, each less than 1,500 words, taken from a simple book from the 1940s about the daily activities of a young boy. They found:

…changes in the objects a character interacted with (e.g., “pulled a light cord”) were associated with increases in a region in the frontal lobes known to be important for controlling grasping motions. Changes in characters’ locations (e.g., “went through the front door into the kitchen”) were associated with increases in regions in the temporal lobes that are selectively activate when people view pictures of spatial scenes.

Overall, the data supported the view that readers construct mental simulations of events when reading stories.

Obviously, they need to repeat this story with people reading science fiction. What parts of the brain do we activate when we read descriptions of far-off planets, aliens, far-future technology and other confabulations for which we have no day to day experience to draw on?

Neurocosmetics: wireheads for congress

neurospasmNeurocosmetics has yet to take off in the backstreets of Birmingham, but is likely to change everything, at least according to Marcel Kinsbourne in his Edge question answer:

…the novel method of deep brain stimulation (DBS), by which electrodes are inserted into the brain to stimulate precisely specified locations electrically, is already used to correct certain brain disorders (Parkinsonism, Obsessive Compulsive Disorder).

Not only are the targeted symptoms often relieved; there have been profound changes in personality, although the prior personality was not abnormal.

A patient of lifelong somber disposition may not only be relieved of obsessions, but also shift to a cheerful mood, the instant the current is switched on (and revert to his prior subdued self, the instant it is switched off). The half empty glass temporarily becomes the glass that is half full. The brain seems not entirely to respect our conventional sharp distinction between what is normal and what is not.

Paging Larry Niven, Arthur C. Clarke, Iain Banks, Greg Egan et al – but how will society change when people are free to choose their personalities at a whim?

In fact, could that be the solution to the Fermi Paradox? Could it be that all technological civilizations advance to the point where they develop a technique for inducing whatever their alien equivalent of permanent happiness is and then stop developing?

If you can track down a copy Arthur C. Clarke’s The Lion of Comarre deals with a similarly themed subject rather well.
