Anti anxiety

Sian Beilock
Writing has been shown to replace ruminating. Ruminating is generally thought of as the mental activity devoted to replaying past traumatic experience. It is a well-known contributor to clinical depression. That’s why writing workshops are often included in the treatment of depression. However, ruminating over future events, such as taking a high-stakes exam or something, can be equally disruptive. In this case, ruminating often leads to “choking” where students perform more poorly than expected given their skill level, especially when there are large incentives for optimal performance and negative consequences for poor performance. University of Chicago Psychologist Sian Beilock has found that the simple act of writing about anxiety can significantly reduce students’ chances of choking, especially if it’s done just prior to test-taking [link]. She says that when students are able to express their fears in writing, they’re given the satisfaction that they’ve dealt with them enough to move on and stop ruminating over them. This, in turn, releases space in working memory ..making it available to work on the task at hand.

Reception

In 1998, psychologist Arthur Graesser examined the real-time components of speech and reading comprehension. See [Einstein’s Dreams]. Components of comprehension include things like ‘syntax parsing’, ‘semantic processing’, ‘unexpected event-handling’ and ‘resolution’. They can be measured in milliseconds. Using an interactive computer-presentation, he recorded the time students spent at each component-step. Sort of like a reaction-time study. What he found was counterintuitive. Comprehension scores were actually higher for students who took longer to process the semantic and unexpected components of a narrative. Students who spent less time performing these tasks scored lower. On closer examination, he found that they were interpreting events way too fast to derive the most likely meaning. Neglecting these early steps also put them at greater risk of misunderstanding whatever happened next. What this tells me is that receptivity and a sense of wonder are far more important than coming to the most expedient conclusion when following what another person is saying.

Academic freedom

The other day students asked me why we waste money on research that doesn’t have immediate medical or commercial value. It was a fair question. I told them I thought it was because progress often depends on research that was originally done for non-commercial purposes ..like scientific advancement. The Internet came to mind. The Internet and all the social networking and businesses it hosts ..did not start out as a texting or commercial enterprise. It was an experiment that relied on research coming out of fields such as cybernetics and neuropsychology. The head of the project was a psychologist from MIT named Joseph Licklider [link]. He was a leading expert on the nature of the auditory system. His research involved understanding the way signals travel across the nervous system and get converted to sound by the auditory centers in the brain. His findings became the basis for ‘packet switching’ in computer networks, without which the Internet would have never progressed much farther than the telephone [link]. These studies were not originally intended for use by the computer industry ..nor were they funded by drug companies. The Internet would have never come about through corporate sponsorship alone. That’s the reason why scientific inquiry needs to be conducted in a neutral setting.

Conspiracy theory

It was the intention of the Bush administration to raise unemployment and drive more middle-class citizens to lower economic classes. They felt it was necessary to get middle-class Americans to accept lower wages. Lower wages mean lower prices and greater demand for American-made products, which helps balance the trade deficit. Reduced purchasing power also means less tolerance for high-priced foreign oil, which helps domestic oil companies expand their operations into coastal waters as well as wildlife sanctuaries. Furthermore, they figured it would discourage fanatics from developing renewable energy sources. A larger class of low paid workers creates greater competition for low-paying jobs. Greater competition for low-paying jobs is how you get the job market to deal with immigration. Fear of foreign workers helps Republicans enact tougher immigration laws ..like denying immigrants any chance of citizenship, which also goes for their American-born, college-educated children ..as well as those serving in the military. Another advantage of the politics of fear is that it helps Republicans win elections. That’s probably what helped Republicans gain control of Congress. Records show that the more support there is for republican issues in congress ..the more cutbacks you can expect to see in public education (especially in the form of federal grants and student aid). Cutbacks such as these deny middle-class access to higher education. What was their intention ..? To create a larger pool of low-cost labor. These advantages are short-term however, and the cycle will turn. When the disparity becomes so great that higher education becomes a luxury only the wealthy can afford, they might as well shut down the state universities ..there aren’t enough wealthy students to go around. When the GOP cuts all ties with the Latino community, and their efforts at stemming immigration fail (because it’s like trying to stop water) ..they’ll have succeeded in creating a larger population of democratic voters. And when support from the rural Midwest farmer collapses because they haven’t kept their promise to repeal the estate tax ..the cycle will come full circle.

Social perception

I have a theory. An awful lot of what we find ‘attractive’ is determined by what we see our peers paying attention to while we’re growing up. I mean during the formative years of 13 to 29. Experts in human development call this a ‘cohort group’. So, to express my theory another way: Our social perception is determined by the cohort group we belong to. For example, the cohort group that came of age after World War II (during the fifties) had greater respect for people in authority and admired commanding-looking leaders. They elected a war hero for president. Larger-than-life actors like Sophia Loren and John Wayne captured their imagination. They also valued conformity. That’s why affluent-looking crooners like Frank Sinatra and Dean Martin sold millions of records. However, the cohort group that came of age during the Vietnam War (the sixties and seventies) had lost respect for heroes and people in authority. Their attention turned more toward realistic-looking actors like Mia Farrow and Jack Nicholson ..as well as less affluent-looking musicians like Bob Dylan and the Rolling Stones (although they’re certainly affluent now). I hear evidence of this almost everyday. People of my father’s generation tell me they don’t find present-day actresses as appealing as the bombshells of the fifties. They say things like: “Hollywood just doesn’t make ‘em the way they used to” and point to reasons like “Today actresses suffer from mediocrity and over-exposure.” However, from the perspective of someone in my cohort ..that’s exactly what makes them appealing. What they call over-exposure ..I call peer-attention. And what they interpret as mediocre ..I see as realistic. That’s why I find actresses today equally, if not more attractive than actresses of the past. But hey, don’t take my word for it ..the film industry banks on it. The target group for moviemakers used to be people between the ages of 13 and 25. Not anymore. It is now people in their forties. They are less likely to stay at home playing X-box ..and they prefer watching movies with actors from their own generation. That’s why now, more than ever .. the screen-life of an actress lasts well into their forties and fifties. Look at the successful careers of Meryl Streep and Julianne Moore. Which brings me back to my theory ..greater realism equals greater appeal to moviegoers of my generation. Either that or I could say: “Hey, Hollywood must not have built ‘em to last in the fifties.” Or some such bull shyte.

The advantages of ADD

The kind of focused attention ordinarily required in a classroom is not all that helpful overcoming obstacles outside the classroom. A wider focus of attention, which is usually associated with ADD, is actually more adaptive according to neuroscientists John Kounios and Mark Beeman [link]. And from what I’ve seen, I believe it ..! They found that when students are more receptive and open to distraction, they do better navigating a computer-simulated labyrinth than when they are focused and blocking out distractions (as seen on an fMRI). Students actually see and hear more .. finding their way faster by heuristic than by analytic reasoning. In other words, discovering relationships between vague and loosely connected information was more advantageous than step-by-step analysis.

I found the same thing to be true once while I was applying for a home loan. After obtaining the 1st mortgage ..I was looking for a bank to help me with the down-payment. After three banks turned me down because they considered this ‘risky’ and ‘somewhat irresponsible’ ..I sat on the beach, got over the feeling that I was ‘risky’ (and somewhat irresponsible) ..and pulled together the real reasons why. They had nothing to do with my ability to meet my obligations. It was not a personal failing on my part but a circumstance of the recession (i.e. time required to find a buyer for my prior home). When I put this and other reasons down in a letter-of-explanation ..the next bank understood intuitively and, with just a couple of questions ..they approved my application.

Biomimicry

Notes from Bioengineering Conference, Nov 25, Long Beach, CA

I like to follow developments that that are the result of ‘biomimicry’. Then again, I’m weird like that. However, I think it’s something that merits attention. Biomimicry is the practice of overcoming obstacles by seeing what works in nature. Naturalistic observation is just as valid as ‘laboratory observation’ in science. According to the speakers today, discovering how things work in nature has inspired breakthroughs in computer technology, renewable energy and regenerative medicine, just to name three.
Renewable energy: Biologists observing the motion of humpback whales have found more efficient ways to capture energy from the wind. They noticed how the saw-tooth bumps (tubercles) that line the edge of a whale’s fin help them perform better in slow-moving water. When they line the edge of blades on a wind-turbine with similar bumps; the blades rotate faster in response to slow-moving wind. This has led to the installation of more efficient and lower-profile ‘wind-mills’ in the desert outside of Palm Springs.
Regenerative medicine: Psychologists observing the natural development of language have made contributions to the field of regenerative medicine. They saw how children learn grammar as a result of social interaction ..with little or no coaching. When they simulate the social environment of early childhood; stroke victims make faster progress toward recovering language skills. This has led to the design of training-programs, hosted as video games ..that are more interactive and engaging. Results can be seen in speech performance as well as on MRI scans of the brain.
Closing remarks: Geoffrey Spedding, an engineer from USC, talked about limits to what we can learn from nature. He says “… the designs that come through evolution are just good enough to survive, that’s all. Nature has yet to come up with a decent wheel.” I had to disagree. In my humble opinion, evolution did produce an information-processing device capable of infinitely more ..the human brain. So, however indirect ..nature did invent the wheel.

Sirens of Titan

Is it a coincidence that the Cassini space probe inexplicably stopped sending images as it was about to fly by Titan, one of the moons of Saturn [link]? Titan is known to harbour conditions necessary for life. Another place considered a likely candidate for extraterrestrial life is Europa, one of the moons of Jupiter. However, the canyons of Europa have eluded attempts at observation as well [link]. Early radio astronomers claim to have received signals, leaking from Titan, that suggest the presence of an extraterrestrial species. However, they are trapped and shielded from detection by parasitic aliens from another galaxy ..aliens who have been exploiting Titan’s resources for eons [link]. This explains why conditions there have deteriorated to an almost “pre-biotic” state. The result has been a sort of reverse-geo-evolution. In it’s day, Titan could have been just as hospitable a place as Earth is today.

Quality of understanding

“The meaning of a sentence is derived from the original words by an active, interpretive process. The original sentence that is perceived is rapidly forgotten and memory is for the information (meaning) contained in the sentence.” [Link]
For years, neuro-linguists have studied what remains after we hear somebody speak. What they’ve come up with is something that resembles a three-dimensional network inside of our head. The network is made up of propositions (coded events), scripts (a sequence of coded events) and associated images and feelings. Although part of the network is constructed from the original sentences ..most of it is supplied from the past experience of the listener. What we come away with is a feeling of resonance and familiarity, based largely on our own beliefs and experience ..and not necessarily the meaning intended by the speaker. These finding are consistent with the construction-integration model for narrative comprehension proposed by psychologist Walter Kintsch [Link]

Narrative space

Proceedings from the Symposium on Extraterrestrial Psychology

Dr. Latimer: Language is nothing more than a stream of symbols that signify nothing until we recognize something we might have either seen or heard before, and look up it's meaning in our mental dictionary. In a plurality of worlds, without a common store of experience that comes from shared culture, efforts at communication may be an exercise in incomprehensible gestures. Verbal communication is the manipulation of symbols to which meaning is assigned by culture. An important point to keep in mind my friends is that the events experienced by members of a culture over time are what make up the narrative thread of that culture.

Dr. Zhavern: When we look into space, we don’t see things as they are. What we see is a single narrative thread winding it’s way through the cosmos ..a cosmos that may be shared by narratives other than our own. However, to it’s participants ..each narrative looks like the only cosmic game in town. Like language, we skew space to resemble something we’ve either seen, or heard before. It’s the only way we can come to grips with it.

Dr. Orloff: I think human consciousness is a fragmented and unstable process. It creates rapid models of counterfactual worlds inside the brain for things it cannot observe ..but only infer. The brain keeps track of these different versions until only those that contribute to narrative coherence receive sufficient signal strength to survive while those leading nowhere dissolve into noise ..and disappear into non-narrative space .. in an instant.

Dr. Pangloss: I think consciousness is made up of searchlights, projected from different mental versions of the world we create. They eventually converge to form concentric circles in the brain that illuminate the focal points that contribute most to narrative events, and fade rapidly at the periphery with fewer contributing points until things go black somewhere around the edges of non-narrative space.

My feeble brain ( hasn’t got a clue ): Are you saying that the narrative threads of extraterrestrials aren’t likely to uncoil very closely to ours ..(?)

PTSD

The military is known for instilling leadership and teamwork ability ..skills that battle conditions can quickly take away. According to a Rand study, nearly one third of all returning troops suffer from some form of post-traumatic stress (PTSD) or traumatic brain injury. Some of them show up at student services where I see them. James was part of a tank crew. On a hot day in Iraq ..they left the hatch open. That’s when a grenade blast slammed his head against an iron plate. At home, he enrolled in college using his GI benefits. However, crowded classrooms make him feel trapped and panicky. When he tries to contain these feelings, he finds he can’t make sense out of what the instructors are saying. Answering a question is like trying to find the answer to a riddle. He mumbles and strains to put together a coherent sentence ..and hopes he’s somewhere in the ballpark. I referred him to the VA for therapy. A short time later he quit school and went looking for a job. He hoped the skills they taught him in the service would help. Unfortunately, many employers told him they couldn’t accommodate time off for therapy. When I talked to him about it, he said he didn’t think that was the real reason. “They hire the disabled all the time” he says “Guys that need just as much time off as I do. No, it’s more like they’re afraid I’ll go postal or something. Head-cases make them nervous.”

Extraterrestrial psychology

Astrophysicist Gregory Benford says we need to consider extraterrestrial economics when looking for signals from outer space. He suggests SETI narrow down its search to what we can reasonably expect extraterrestrial to achieve at such great distances ..assuming they’re not omnipotent. I applaud him for his pragmatism, however I think we also need to consider extraterrestrial psychology if we are to expect a reasonable chance of successful contact. Otherwise, I don’t see how we hope to achieve any kind of meaningful communication. Since we have no basis from which to conceive of the extraterrestrial mind, I think we have to start with something we can observe ..and I believe that would be us.
Psychologists already know that rational thought is a spatio-temporal process. It’s powerful but limited to weighing evidence about the physical universe. Other-worldly experience is out-of-scope. I believe this would also apply to the thought processes of any aliens we encounter. First, we’d only know we’ve encountered them if they share the same spatial-temporal dimension as us. Second, those we do meet would have to have some way of processing information about this shared dimension that is similar to ours. In other words, like us .. they would also have to integrate sensory information into a coherent model of the world they inhabit. So, I believe the first step in contemplating extraterrestrial life is to better understand our own. I mean, lets face it .. at this point it’s all we got.
Science tells us that knowledge is often knowledge of differences. Given that the human brain is tuned to receive only a narrow band of information available on earth, which is further constrained by culture ..I’m not sure it’s safe to assume that the alien mind is similarly tuned. They do not share the same background. We know that human perception is based on background information as much as information from the present ..and that the brain integrates information selected by the senses with information available in memory to create a coherent whole. I don’t think it’s reasonable to expect extraterrestrials, who do not share our planetary history, to perceive our surroundings the same way we do. The way I’ve heard it explained best goes something like this:
“We could try and introduce ourselves to them ..but all they might see is a sparse dusting of energy waves occurring in a vacuum ..with some probability of identity based on their backgrounds ..not ours.”

Age of Inception

From the moment the movie “Inception” was released, polls have shown it’s appeal is split along generational lines. Many “older” moviegoers hate the film while younger people have nothing but good things to say about it. According to Henry Jenkins, a professor of cinema at USC, this has everything to do with video game experience. He says “Inception is first and foremost a movie about worlds and levels, which is very much the way video games are structured.” While I agree that gaming experience may be a factor, I’d say a bigger reason is that members of prior generations don’t understand, or accept the film’s premise. As DiCaprio’s character describes it, conscious experience is not a literal transcript of the world, but an ongoing process of virtual construction by the mind. Although this premise has scientific merit, it is not widely known or embraced by the majority of tradition-bound Americans.

Kerry: this is what I meant by a cohort effect when trying to understand differences of opinion. I'll post Dr Henry Jenkins reply next. It’s way brilliant..!

Working memory

It was interesting for me to see a recent study in neuroscience that supports my theory of reading comprehension ~~>[Pragmatic inferences in reading]. Bear with me while I try and explain (or you can duck out now and I won’t be offended). What they found is that working memory interacts with the senses in order to produce a stable view of our surroundings and reduce errors of perception. For one thing, it has to identify signals that are the result of actual sensory events and filter out extraneous signals that are produced by fluctuations inside the nervous system itself (like those caused by changes in activity levels, neurotransmitter concentrations, circadian rhythms, etc..). Neuroscientists refer to this as the ‘sensory orientation’ function. The visual areas in the brain must distinguish changes in actual sensory events from changes in internal activity in order to follow the ‘genuine’ action. They claim that the brain makes this estimate based on principles of ‘Bayesian inference’, which are not much different than principles of ‘Pragmatic inference’. It works something like this. Incoming signals that are considered likely to occur based on the contents of working memory are boosted, whereas signals considered less likely are held in abeyance and immediately suppressed if subsequent events don’t do anything to rehabilitate them. These findings were published in the August 26th journal PLoS One ~~> [Sensory adaptation for a changing brain]. Hah!

Altered state of California

The outcome of legalizing marijuana in California won’t be what you might expect. It doesn’t signal the end of western civilization because laws don’t make that much difference. Most people I know take it or leave it for reasons of their own. I do expect to see a big drop in the price of marijuana. In anticipation, local governments are going to impose a usage tax instead of a sales tax for marijuana purchases. So, even though the price will go down to something like $38.00 an ounce ..we will be paying an additional $50.00 to $100.00 an ounce in fees. I expect this will result in a black market created to avoid paying these fees, which means there will be less money than anticipated for state revenue and we’ll be back to the days when we busted marijuana users for tax evasion. I can’t imagine Humboldt County pot farmers are too enthusiastic. At roughly $14 billion a year, marijuana is the largest cash crop in California. Legalization will definitely take a bite out of their profits. The biggest factor in the price structure is the risk of getting caught. However, in Humboldt they’ve already offset that risk with fees paid to local law enforcement agencies to look the other way. You can do that when you’re the biggest player in the local economy. They may be able to offset their losses by selling to other states. Interstate commerce will be lucrative since it will continue to be a federal offense. I hope there’s a way to create a legal supply chain from the ‘emerald triangle’. They produce the finest quality marijuana in the land ..no one else comes close. One factor that may defeat proposition 19, in addition to overblown fear ..is the loss expected by the legal establishment. Police officers, attorneys, courts and penal institutions are built around treating marijuana users as criminals. I can’t imagine defense attorneys sitting idly by while two thirds of their clientele are about to disappear. Confusing as it might sound, I do hope proposition 19 passes. It’s a step in the right direction. I’ve seen criminal penalties ruin more young lives than marijuana ever did.

Socialist Republic of California

I remember when I was going to college, I often heard conservatives from the generation before me refer to it as ‘the socialist state university of California’ ..and a typical exchange might go something like this:
“So Bill, what are you doing for your thesis ..?”
“Studying how people can be easily misinformed ..like deceptive advertising, that sort of thing.”
“Oh, so you can devise better methods of propaganda ..”
“No, so we can teach better methods of detecting it ..”
Later, I would discover that they were going around saying: “Hey, did you know Bill is studying to be a propaganda minister.” At first, I took it as a joke ..and laughed it off. Then one day I kind of got the gist of it when someone at work got real pissed and told me how unfair it was: “Even though I didn’t go to college, I have to pay so punks like you can.” And I thought, yeah .. it was part of a land-grant act to set aside state funds for higher education. Later I discovered some people actually believe universities teach communist principles. Why ..? Because, as the name implies, universities teach universal principles, paving the way for a one-world society. And here I thought they were teaching us how to communicate better with other societies. When I look at the wars we’ve been fighting, I realize how easily misinformed I have been.
