In this NEW YORK TIMES article from today, scientists reveal their latest findings about which brain cells are excited during the recall of memories, and how closely memory tallies with literally re-enacting the events. And they use a tantalizing example:
After briefly distracting the patients, the researchers then asked them to think about the clips for a minute and to report “what comes to mind.” The patients remembered almost all of the clips. And when they recalled a specific one — say, a clip of Homer Simpson — the same cells that had been active during the Homer clip reignited. In fact, the cells became active a second or two before people were conscious of the memory, which signaled to researchers the memory to come.
Why is Homer Simpson singled out as the test case? Obviously because the human brain has specific neurons that emulate or actually induce and compel Homer-Simpson-style behavior.
And there in a nutshell you have the whole basis for ninety-nine percent of the contents of WEIRD UNIVERSE.
Candid Camera was, in my opinion, the greatest TV show about psychology ever made, and this is one of its classic segments: Group behavior in elevator. It speaks volumes about the human need to conform.
Another segment I like is "The Interpreter," from the British Candid Camera. Watch as the interpreter never questions the romantic advances the woman makes toward him, even though her "fiancee" is sitting beside him.
The goal is to discover how individuals perceive the behavior of helpfulness.
The first step is to conduct a survey with as many participants as possible. That’s where you come in. The survey takes about 30 minutes and can be found at www.socialpsychresearch.org.
I took one look at the length of time and thought, "30 minutes! I don't want to take a survey for that long!" I'm basically unhelpul and selfish. But this made me realize that the only people taking the survey will be those that are more helpful than most. It'll be a biased sample.
Zimbardo and his co-researchers are very smart people, so I'm sure they realize this. I'm guessing that the real purpose of the survey may be to find out how many people actually take it, versus how many visit the link. That could provide a quick snapshot of how many helpful people there are on the internet. (Thanks to Joe Littrell!)
Have you ever noticed that some people, when their picture is taken, tilt their head to the side? The behavior is called head canting. I never knew this until I stumbled upon an article titled "Head Canting In Paintings: An Historical Study" in the Journal of Nonverbal Behavior (Spring 2001).
Some factoids about head canting:
Researchers speculate that it's a submissive gesture. Erving Goffman described it as "a form of ingratiation or appeasement achieved by reducing one's overall height."
The authors of the "Head Canting in Paintings" article examined 1498 figures in the works of 11 painters from the 14th to the 20th centuries. They concluded that, throughout history, head canting has been associated with submissiveness:
religious and mythological figures exhibited much more head canting than commissioned portraits. This finding supports the idea that head canting is strongly connected with the expression of submission, appeasement, ingratiation, and request for protection... In contrast, in paintings portraying nobles, professionals, and artists, head canting was minimal or absent.
Are musicians placing hidden (often Satanic) reverse lyrics in their music? It's an old controversy, but also one that can offer an interesting psychological demonstration of the power of perceptual expectation. Which means, in plain English, that our brain makes our ears hear what it expects to hear.
But next click the button to reveal the reverse lyrics that you're supposed to be able to hear and listen to the reversed music again. You should now be able to "hear" the reverse lyrics... because your brain is expecting to hear them. The British Psychological Society's blog writes:
Once the expectations for what to hear are in place, they can't be undone. You can't unhear the devilish lyrics once you know about them. This is a powerful demonstration of how our perceptual experiences are based not just on what is served up by our senses, but also on what our brains bring to the table.
My favorite reverse lyric was the one in Pink Floyd's Empty Spaces.
If you were sitting in a waiting room and smoke began to billow out of a vent in the wall, you'd probably do something about it. At least, you'd report the problem to someone. Or maybe not.
In a famous experiment conducted by John Darley and Bibb Latané during the 1960s, Columbia University students were invited to share their views about problems of urban life. Those who expressed an interest in participating were asked to first report to a waiting room in one of the university buildings where they would find some forms to fill out before being interviewed. They had no idea that the urban-life study was just a cover story. The real experiment occurred in the waiting room.
As they filled out the forms, smoke began to enter the room through a small vent in the wall. By the end of four minutes, there was enough smoke to obscure vision and interfere with breathing. Darley and Latané examined how the students reacted to this smoke in two different conditions.
In the first condition, the students were alone. When this was the case, they invariably investigated the smoke more closely and then went out into the hallway to tell someone about it.
But in the second condition, the students were not alone. There were two or three other people in the room, who were secret confederates of the researchers. They had been instructed to not react to the smoke. They would look up at it, stare briefly, shrug their shoulders, and continue working on the forms. If asked about it, they would simply say, "I dunno."
In this setting, according to Darley and Latané, "only one of the ten subjects... reported the smoke. the other nine subjects stayed in the waiting room for the full six minutes while it continued to fill up with smoke, doggedly working on their questionnaires and waving the fumes away from their faces. They coughed, rubbed their eyes, and opened the window -- but they did not report the smoke."
Norbert Elias (1897-1990) was a highly influential sociologist, best known for his two-volume work The Civilizing Process. Among his less well-known accomplishments was his shoelace experiment.
In 1965 and 1966 Elias traveled throughout Europe as a tourist. Deciding to mix sociological research with pleasure, he resolved to find out how people in different countries would respond to him if he left his shoelaces untied. Ingo Moerth summarized the results of this experiment in the June 2007 issue of The Newsletter of the Norbert Elias Foundation:
(1) Spain - Torremolinos 1965 (upper village): In the mostly touristic context of ‘upper’ Torremolinos the loose shoe-laces were sometimes noticed, but never communicated, which Elias explained by a predominantly anonymous Gesellschaft context, brought about by a predominance of tourism.
(2) England - London 1965 (Regent Street, Bond Street): Here Elias conducted three experiments, all of which lasted three hours. He got nine reactions, mostly by older ‘citizens’, as Norbert Elias notes: ‘In England mostly elderly gentlemen reacted by communicating with me on the danger of stumbling and falling’ (in Elias 1967, as translated by Ingo Moerth). This might be interpreted as an established ‘society-context’, where the anonymity is overruled by engaged and experienced citizens watching the public space.
(3) France - Paris 1966 (Champs Elyseés, Boulevard St Michel, Montparnasse): Here Elias conducted three experiments of three hours, but with much less reaction. Only two people communicated directly with him about the visible shoe-lace problem, both sitting in street cafés on the Champs Elyseés, besides a youngster who shouted directly ‘prenez garde’ (‘take care’) into his ear, much to the amusement of the young man’s group of companions. As an explanation of this different reaction, perhaps a different character of ‘public space’ in France may be relevant: mere observation in contrast with engagement and direct intervention, as in London/UK or in Germany (see the following discussion, as cited below).
(4) Germany - for instance Münster 1965: Here the ‘society-context’ mentioned above was – according to Norbert Elias – watched and communicated not by gentlemen, but mostly by women: ‘In Germany older men only looked at me somewhat contemptuously, whereas women reacted directly and tried to ‘clean up’ the obvious disorder, in the tramway as well as elsewhere. Here in most cases a short conversation, comprising more than the obvious ‘shoe-lace disorder’ took place, such as a short warning about what might happen if I didn’t take care of the basic problem’ (in Elias 1967, as translated by Ingo Moerth).
(5) Switzerland: Bern 1966: Here Elias experienced the most elaborate conversation about dangers related to untied shoe-laces, including admonitions about dangers of eating grapes and using trains. He explicitly states: ‘This was probably an exception, from which no conclusion on a Swiss national character can be drawn' (in Elias 1967, as translated by Ingo Moerth).
It would be interesting to conduct this experiment in America. New Yorkers would probably ignore you. In Los Angeles everyone drives, so you'd be lucky if you encountered another pedestrian.
The Edmonton Sun offers this description of a bizarre murder that occurred in 1887 near Canada's Slave Lake:
Marie Courtereille, 40, died after being struck four times with an axe -- twice by her husband Michel Courtereille and twice by her son Cecil. Testimony at their trial indicated that Marie had begged to be killed because she believed she was possessed by a Windigo, telling them, "I am bound to eat you." Over a period of several weeks, she became increasingly aggressive, "roaring like an animal" and attacking her husband.
Eventually, she was tied down and guarded around the clock until it was decided that there was no choice but to kill her. The community supported the killing.
A Windigo (also spelled Wendigo) is a creature from Algonquin mythology. The Algonquins believed that Windigos were malevolent spirits who could possess people, transforming them into "wild-eyed, violent, flesh-eating maniacs with superhuman strength." Horror fans will be familiar with Windigos, since they've featured in a number of horror books and movies.
The term "Windigo psychosis" describes a psychological condition in which people who believed they were possessed by a Windigo would go on cannibalistic rampages.
Many researchers regard Windigo psychosis as something of an Algonquin urban legend, but ethno-historian Nathan Carlson argues that it was a real phenomenon "which haunted communities right across northern Alberta in the late 19th and early 20th Centuries and cost dozens of lives." Carlson is working on a book that will documents dozens of cases of Windigo psychosis. Sounds like fun reading.
Hitachi recently announced that in 2010 they plan to unveil a 5TB hard drive. This led them to note that, "By 2010, just two disks will suffice to provide the same storage capacity as the human brain."
So, according to Hitachi, the brain has a 10TB storage capacity. But how did they arrive at this number?
There's been a lot of speculation about the brain's storage capacity. The most popular method of arriving at an answer is to estimate the number of synapses in the brain and extrapolate from there. This has led researchers to come up with numbers ranging anywhere from 3TB to 1000TB. Hitachi evidently was using this method.
But there's a second method (noted on the Of Two Minds blog). Psychologists have conducted experiments to measure how much information people are actually able to memorize. This produces much smaller numbers. They've concluded that it's only about two bits per second, or a few hundred megabytes averaged over an entire lifetime.
Of course, until scientists figure out a way to allow us to download our brains to computers, all these numbers are just useless trivia. And when that happens, we can all plug into the Matrix and live happily ever after.
Two Montreal shrinks believe they've uncovered a new clinical-grade delusion
Five patients tell them they're certain they're being secretly filmed 24/7 for reality TV shows ("Truman Show Delusion"). We already know about Capgras Delusion (your family's being replaced by lookalike pod people) and Fregoli Delusion (a particular person is dedicated to bringing you down). But veterans in the field say the new one is all of a piece with the old ones. (Capgras was famously in the news last year when former Saturday Night Live actor Tony Rosato was battling the demon.)
