A few decades ago they had a hunch that the number of active verbs in your sentences or what adjectives you use (lovely, sweet, angry) reflect personality traits.</p><p>They have painstakingly pinpointed various insights. For example,&nbsp;<a href="http://homepage.psy.utexas.edu/homepage/faculty/pennebaker/reprints/SuicidalPoets.PDF" target="_blank">suicidal poets</a>, in their published works, use more first-person singular words (like &quot;me&quot; or &quot;my&quot;) and death-related words than poets who aren&#39;t suicidal. People&nbsp;<a href="http://docs.lib.purdue.edu/jhpee/vol5/iss1/6/" target="_blank">in positions of power</a>&nbsp;are more likely to make statements that involve others (&quot;we,&quot; &quot;us&quot;), while lower-status people often use language that&#39;s more self-focused and ask more questions. Comparing genders, women&nbsp;<a href="http://www.tandfonline.com/doi/abs/10.1080/01638530802073712" target="_blank">tend to use</a>&nbsp;more words related to psychological and social processes, while men referred more to impersonal topics and objects&#39; properties.</p><p>(This&nbsp;<a href="http://homepage.psy.utexas.edu/HomePage/Faculty/Pennebaker/Reprints/Tausczik&amp;Pennebaker2010.pdf">2010 paper</a>&nbsp;in the&nbsp;J<em>ournal of Language and Social Psychology</em>&nbsp;goes into great detail about the so-called &quot;psychometrics&quot; of words.)</p><p>This research suggests that Internet companies such as Facebook and Google, with their troves of written expressions, are sitting on powerful insights about us as people. But if you ask them, &quot;Hey, can you give me the take on me that you&#39;ve got in-house or that you&#39;ve built for advertisers, with my anonymized data?&quot; &mdash; they won&#39;t give it to you. I actually did ask, and they don&#39;t have that kind of offering.</p><p>But I&#39;ve found someone who does: IBM&#39;s Watson division. Researchers there have taken the personality dictionaries already created by scientists, dropped them into Watson (the computer that won Jeopardy), and sent it off to apply it to people on Twitter, Facebook, blogs. That forms a digital population of people and personality types. Over time, more text from more people will help Watson get smarter. (Yes, this is machine learning.)</p><p>In&nbsp;<a href="http://www.ibm.com/smarterplanet/us/en/ibmwatson/developercloud/doc/personality-insights/science.shtml#researchMedia">its own studies</a>, IBM found that characteristics derived from people&#39;s writings can reliably predict some of their real-world behaviors. For instance, people who are less neurotic and more open to experiences are more likely to click on an ad, while people who score high on self-enhancement (meaning, seek personal success) like to read articles about work.</p><p>For IBM, these kinds of interpretations can become a business opportunity.</p><p>Understanding people in order to sell them things is obviously a very big business&nbsp;<a href="https://hbr.org/2015/11/quantifying-the-impact-of-marketing-analytics?utm_source=twitter&amp;utm_medium=social&amp;utm_campaign=harvardbiz">for marketers</a>. IBM&#39;s senior researcher Rama Akkiraju suggests other uses: by public relations firms looking for journalists who sound friendly on a specific topic; by editors who want their writers to set a certain tone; by employers looking for a worker who fits their corporate culture.</p><p>&quot;We&#39;re moving to make it easier for people to consume insights,&quot; she says.</p><p>This use of Big Data, of course, raises serious privacy concerns, which&nbsp;<a href="http://www.npr.org/tags/126394606/privacy" target="_blank">we have examined</a>&nbsp;in many stories. In this exploration, I decided to take a deep dive into Watson&#39;s personal insights &mdash; what they can teach me about my career choices and my love life (yep, really went there).</p><p><a href="http://one.npr.org/?sharedMediaId=460641423:460728815">You can listen to my story on NPR One</a>.</p><p>Not all of the tools I used are publicly available, but you can try out a couple of them.

The pie chart it spits out from a person&#39;s social media posts, which you saw above, is a messy hodge-podge of about 50 traits. Plus, given how people curate their digital presence, the words we use online may be a highly biased indicator of who we are.</p><p>&quot;It&#39;s very interesting as a general curiosity,&quot; says Sina Khanifar, a San Francisco-based technologist, &quot;but what would really get me excited is if it made a particular recommendation.&quot;</p><p>Khanifar says many tools exist to help you quantify yourself, track your running speed or breathing patterns. What few of them do is actually suggest how to improve your life. And, he says, people don&#39;t just want to pay for insight. &quot;When you go to see a therapist, it is about self-knowledge. But it&#39;s also about a change.&quot;</p><p>A friend recently mused about what this kind of tool could do for dating. People lie about themselves on dating sites chronically. What if Google developed a service to mine your mail and search and paired you with the perfect partner?</p><p>That could be amazing, or amazingly creepy.</p><div id="res460602444" previewtitle="IBM's Watson analyzes a Twitter account of an unnamed user, breaking down needs, values and five personality traits: openness, conscientiousness, extroversion, agreeableness, neuroticism (aka emotional range)."><p><em>Editor&#39;s Note: This post accompanies a story that you can hear on the&nbsp;NPR One&nbsp;app by&nbsp;<a href="http://one.npr.org/?sharedMediaId=460641423:460728815">following this link</a>.</em></p></div><p>&mdash;<a href="http://www.npr.org/sections/alltechconsidered/2015/12/22/459954667/i-asked-a-computer-to-be-my-life-coach?ft=nprml&amp;f=459954667" target="_blank"><em><u>via NPR</u></em></a></p></p> Wed, 23 Dec 2015 16:43:00 -0600 http://www.wbez.org/sections/science/i-asked-computer-be-my-life-coach-114278 The psychology behind superstitions http://www.wbez.org/programs/morning-shift/2015-11-13/psychology-behind-superstitions-113775 <img typeof="foaf:Image" src="http://llnw.wbez.org//main-images/fingers crossed flickr ~dgies.jpg" alt="" /><p><p>Stevie Wonder says if you believe in things that you don&rsquo;t understand, then you suffer.

No,&rsquo;&rdquo; she says. &ldquo;And then one day, a friend who was working at Reuters tricked me.&rdquo;</p><p>The friend invited Michael for a bite to eat...but took a detour.</p><p>&ldquo;Instead of going to lunch, we walked onto the trading floor,&rdquo; she recalls.</p><p>This was the famous &lsquo;pit&rsquo; at the Chicago Mercantile Exchange in the old days, before electronic trading. It was crowded with guys in colorful jackets &ndash; and they were all guys back then &ndash; shouting, waving their hands, literally jumping up and down to make trades. Some of them worth millions of dollars. Non-stop.</p><p>&ldquo;I walked on, I was like, OH MY GOD,&rdquo; Michael says. &ldquo;It was competitive, it was fun, it was exciting. And it&rsquo;s the antithesis, I found out later, of most people that walk on the floor. They walk on the floor, they&rsquo;re overwhelmed. They&rsquo;re like, &lsquo;Oh my God &ndash; what are people doing?&rsquo; And it was a very different experience for me.&nbsp; I really wanted to go and play.&rdquo;</p><p><img alt="" class="image-original_image" src="http://www.wbez.org/system/files/styles/original_image/llo/insert-images/BRAIN%20SCAN%20SOUNDCLOUD%20THUMB.png" style="float: left; height: 260px; width: 350px;" title="A snapshot of the human brain highlights the areas associated with rewards, fears, and decision-making. Area B, highlighted in yellow, shows the brain’s “reward center,” which can push us to take risks. (Photo courtesy of Camelia Kuhnen)" />And so she did, for more than a decade, first as a trader and then as a manager at the Mercantile Exchange. Jody Michael says she loved the rush &ndash; including the minute-by-minute risk-taking &ndash; but she acknowledges it&rsquo;s not for everyone.</p><p>So what makes people like Jody Michael different? Camelia Kuhnen at Northwestern&rsquo;s Kellogg School of Management has given the question some serious thought. A neuro-economist, she studies what&rsquo;s going on inside people&rsquo;s heads &ndash; literally &ndash; when they&rsquo;re making financial decisions.</p><p>&ldquo;We get to ask questions that have never been asked before. And you know what? We can even answer them sometimes,&rdquo; she says with a laugh. &ldquo;For example: Why do some people take a lot of risks and others don&rsquo;t? Or: Why are some people confident in their beliefs, and others aren&rsquo;t?&rdquo;</p><p>In some experiments, Kuhnen puts people inside fMRI machines, gives them investments to choose from, and sees which areas of the brain light up. She also looks at their genes, their personalities, and their credit reports.</p><p>Kuhnen describes Jody Michael&rsquo;s experience as an example of a phenomenon called &ldquo;traders&rsquo; intuition.&rdquo;</p><p>&ldquo;It&rsquo;s probably not gonna be just mathematics &ndash; knowing how to deal with numbers and probabilities &ndash; that&rsquo;s gonna make you a successful trader,&rdquo; she says. &ldquo;It&rsquo;s about understanding what everybody else in the market is doing. [Michael] probably was able to understand what all those people in the pit were all doing and talking about &ndash; yelling about, I should say.&rdquo;</p><p>In the midst of all that chaos, Jody Michael was able to &ldquo;read&rdquo; people, and the room as a whole. Researchers have found that this traders&rsquo; intuition is tied to what psychologists call &ldquo;theory of mind&rdquo;:&nbsp; The ability to form a mental picture of other people&rsquo;s thoughts, feelings, and intentions.</p><p>Michael agrees. &ldquo;It wasn&rsquo;t about numbers at all,&rdquo; she says. &ldquo;It was driven absolutely by feeling &ndash; ooh, it feels like I&rsquo;m at home, in the competitive environment and driven by the opportunity.&rdquo;&nbsp;</p><p><img alt="" class="image-original_image" src="http://www.wbez.org/system/files/styles/original_image/llo/insert-images/CBOT%20image.jpg" style="height: 220px; width: 300px; float: right;" title="The Chicago Mercantile Exchange. Former trader Jody Michael says unlike most people she felt right at home in the chaotic risk-taking chaos environment of the famous pit. (Wikipedia)" /></p><p>The beginning of Jody Michael&rsquo;s life on the trading floor provides a window into the psychology of traders. And as it happens, when she left the floor 15 years later it was to go back to school to study psychology. Now <a href="http://www.jodymichael.com/" target="_blank">she&rsquo;s a professional coach</a> to traders. She says she aims to help her clients understand themselves as well as they understand the markets.</p><p>&ldquo;The most important piece of trading is you,&rdquo; she says. &ldquo;As we go into trade, we are shaped by our perceptions, our attitudes, our beliefs, our values, how we think, the moods that we&#39;re in, all of that impacts what we see, what we don&#39;t see, what we take action on, what we don&rsquo;t take action on. That is the psychology of trading.&rdquo;</p><p>And her best example of the psychology in action is a client we&rsquo;ll call &ldquo;Steve.&rdquo; Steve isn&rsquo;t his real name because of client confidentiality, but his story opens up questions about the nature of risk taking. How much of it is hard wired in our brain, and how much of it is what we choose?</p><p>Steve is a hotshot trader &ndash; experienced enough to play the market by intuition.</p><p>&ldquo;He&rsquo;s a sensation-seeking, I-need-a-lot-of-variety kind of guy,&rdquo; says Michael.</p><p>But, when he first came to Michael&rsquo;s office, he wasn&rsquo;t making as much money as he wants.</p><p>Michael&rsquo;s work with Steve takes a few steps: First comes awareness. She helps Steve understand that although he thinks he&rsquo;s just doing one thing all day &ndash; trading &ndash; he&rsquo;s actually doing it in two completely different ways.&nbsp;</p><p>First are the setups: As Michael describes it, this is based on long years of experience. When certain conditions come up, bam! He buys this or sells that, and it&rsquo;s gonna make him a ton of money.</p><p>But they only appear every so often, and meanwhile, he&rsquo;s trapped watching the screens, waiting.</p><p>&ldquo;And he gets bored!&rdquo; Michael says. &ldquo;So in between those trades, when he&rsquo;s sitting around &ndash; and this is where he gets into trouble &ndash; he will just play, going in and out, all day long, to fulfill that need for that feeling: He&rsquo;s in it. He&rsquo;s in the game. He needs to be in the game.&rdquo;</p><p>Camelia Kuhnen&rsquo;s research shows that some people are just like this &ndash; they&rsquo;re born risk takers. She points to a gene called DRD4 that regulates dopamine levels in the brain&rsquo;s reward center.&nbsp;</p><p>&ldquo;Yeah, if you carry the long version of DRD4, you tend to take about 25 percent more risk in your portfolio than other people,&rdquo; she says.</p><p>Jody Michael works with Steve for months, and helps him become aware of the difference between the good trades and the other stuff. She has him practice, training himself to do the opposite of what his instincts tell him. If his brain says &lsquo;go,&rsquo; Steve learns to stop.</p><p>But then Steve starts to falter. He can&rsquo;t stay disciplined in controlling his trading habits.&nbsp;</p><p>&ldquo;What we figured out with Steve was that he had a competing commitment,&rdquo; says Michael. &ldquo;Steve has a strong need to have fun, and play.&rdquo;</p><p>In other words, he was making all these dumb trades because he loved to do it. Or, you could put it this way: He wasn&rsquo;t just yielding to a compulsion to take risks:&nbsp; He was indulging a desire to have fun &ndash; which for him involved taking risks.</p><p>Once he knows the difference between work and play, he gets to choose. And what Steve decides is: He wants to keep playing.</p><p>&ldquo;He acknowledged, &lsquo;You know, I don&rsquo;t care: I love this,&rsquo;&rdquo; says Michael. &ldquo;&lsquo;I just wanna do this.&rsquo;&rdquo;</p><p>So rather than change what he does, Steve changes his attitude. He learns to embrace it.</p><p>&ldquo;What&rsquo;s interesting is that Steve came to me to minimize the risk and to become a better trader,&rdquo; says Michael. &ldquo;And how he ended up leaving was: He was the same trader but at peace with it.</p><p>He makes less money than he might &ndash; but enough that he gets to keep playing. And enough that he can fly to Vegas eight times a year, with money to blow.&nbsp;</p><p>Jody Michael says other traders she&rsquo;s worked with would never make the choices that Steve does.</p><p>&ldquo;They&rsquo;re going to look at the dollar amount and say, &lsquo;Hey, percentage-wise, this is crazy,&rsquo;&rdquo; she says. &ldquo;But you get a guy like Steve, and he makes enough, and he says, &lsquo;I&rsquo;m driven by opportunity, but I also want to play.&rsquo; And he does.&rdquo;&nbsp;</p><p>So what does Camelia Kuhnen&rsquo;s science tell us about what makes Steve so unique?&nbsp; Well, not much. He probably carries the longer DRD4 gene, but genes only account for around 35 percent of behavior, she says. They&rsquo;re just hints, really, about the kinds of risks you might accept.</p><p>&ldquo;Just the pure genetic component, while it&rsquo;s important, is not the only thing that drives behavior,&rdquo; she says. &ldquo;Your own experience matters a lot. Where you were born and how you were brought up matters a lot.&rdquo;</p><p>And, Steve might say: How well you know yourself, and what you choose to do with that knowledge.</p><p><em>Dan Weissmann is a reporter for <a href="http://www.marketplace.org/">Marketplace</a>. &nbsp;Follow him <a href="https://twitter.com/danweissmann">@danweissmann</a>.</em></p><p><em>&ldquo;At What Cost?&rdquo; is made possible in part by the John A.

In the U.S., census data shows that about 20 percent of people speak a language other than English at home. That number has been steadily growing, but it doesn&#39;t account for all the people who learned a foreign language in school, or for some other purpose.</p><p>With that in mind, if we want to better understand how the brain works, how it processes sound and language, it might be a good idea to study the brains of bilingual people. In <a href="http://www.communication.northwestern.edu/departments/csd/research/bilingualism_psycholinguistics/">Northwestern&rsquo;s Bilingualism and Psycholinguistics Laboratory</a>, Dr. Viorica Marian is concerned with doing just that. The lab does research examining the differences of bilingual people in learning and memory from those with a single language.&nbsp;</p><p>In a paper recently published in <a href="http://www.pnas.org/">Proceedings of the National Academy of Sciences</a>, Dr. Marian&rsquo;s lab teamed up with the <a href="http://www.soc.northwestern.edu/brainvolts/">Auditory Neuroscience Lab</a> lead by Dr. Nina Kraus. Graduate student Jen Krizman lead research that uncovered an interesting difference in the way that a <a href="http://www.soc.northwestern.edu/brainvolts/slideshows/bilingualism/index.php">bilingual brain processes sound</a>.&nbsp;Researchers have known that bilinguals excel at tasks that test their attention and this recent <a href="http://www.soc.northwestern.edu/brainvolts/documents/Krizman_et_al_PNAS_2012.pdf">collaboration</a> has helped explain why. &nbsp;</p><p>If you are bilingual, you are always going to have both languages active when you are communicating. So you constantly have to inhibit one language as you engage the other one. Having this bilingual experience leads to advantages in ability to inhibit irrelevent information. Being able to pay better attention changes the way the brain responds to sound and how you are able to focus on the important features of a sound. Basically, the bilingual brain shapes itself into a more efficient sound processor...C&#39;est incroyable!</p><p>In this episode, we also talked with <a href="http://psychology.uchicago.edu/people/faculty/bkeysar.shtml">Dr. Boaz Keysar</a>. He studies language and decision making at the University of Chicago. In a <a href="http://psychology.uchicago.edu/people/faculty/ForeignLanguageEffect.pdf">recent paper</a>, he showed that when people think in their second language, they are less affected by <a href="https://en.wikipedia.org/wiki/List_of_cognitive_biases">decision biases</a>. In a nutshell, he showed that people make different decisions based on the language they&#39;re using.</p><p>It is important to note that the subjects in his experiments were different from those in the Northwestern paper. In the Northwestern experiments, the subjects learned their second language early in life. Dr. Keysar&#39;s work dealt with people who learned a second language later.</p><p>This is important because Keysar&#39;s theory for why thinking in a second language lessens the effect of decision bias like &quot;<a href="https://en.wikipedia.org/wiki/Framing_effect_(psychology)">the framing effect</a>&quot; and &quot;<a href="https://en.wikipedia.org/wiki/Loss_aversion">loss aversion</a>&quot; has to do with the emotional distance a second language provides. A native tongue has a stronger connection to the emotional part of the brain than the second language does. &nbsp;Keysar suggests that thinking in a second language is more analytical because it is not as emotionally anchored. &nbsp;So be careful what language you think in...it could literally change your mind.</p><p>No matter what language you&#39;re thinking in, don&rsquo;t forget to subscribe to our&nbsp;<a href="http://itunes.apple.com/us/podcast/wbezs-clever-apes/id379051174">podcast</a>, follow us on&nbsp;<a href="http://twitter.com/#%21/cleverapes">Twitter</a>, and find us on&nbsp;<a href="http://www.facebook.com/pages/Clever-Apes-on-WBEZ/118246851551412">Facebook</a>.</p></p> Wed, 06 Jun 2012 06:15:00 -0500 http://www.wbez.org/blogs/clever-apes/2012-06/clever-apes-31-%C2%BFhabla-usted-simio-99831 Clever Apes #28: The critter economy http://www.wbez.org/blog/clever-apes/2012-03-20/clever-apes-28-critter-economy-97474 <img typeof="foaf:Image" src="http://llnw.wbez.org//blog/photo/2012-March/2012-03-20/THUMBNAIL_Gorrilla.png" alt="" /><p><p><img alt="Dario Maestripieri studies how humans behave compared with primates." class="caption" src="http://llnw.wbez.org/blog/insert-image/2012-March/2012-03-20/DARIO pic for post.png" style="width: 600px; height: 484px;" title="Dario Maestripieri studies how humans behave compared with primates. (WBEZ/Gabriel Spitzer)"></p><p>It seems like economics is a purely human invention, far removed from the jungle. But scientists say our ancestors were spending and investing for millions of years. So our behavior when we manage our portfolio or climb the corporate ladder resembles nothing so much as the interactions of apes or monkeys. In the latest installment of Clever Apes, we consider how our financial activity has deep parallels in the primate world. And furthermore, many of our most important financial decisions come from even more primitive impulses, deep in our lizard brains.</p><p>The University of Chicago’s <a href="http://primate.uchicago.edu/dario.htm">Dario Maestripieri </a>is a professor of comparative human development, evolutionary biology, neurobiology and psychiatry and behavioral neuroscience. (I usually abbreviate titles, but his makes me happy). He studies the intersections among our minds, our primate cousins, and evolution. In his new book <a href="http://www.amazon.com/Games-Primates-Play-Investigation-Relationships/dp/046502078X">Games Primates Play</a>, he details how the mechanisms of economics have their origins in our deep past.</p><p>Apes and monkeys play the market by choosing whom to groom and whom to attack, whom to sleep with and what food is worth risking a fight for. As Yale psychologist Laurie Santos explains, the psychology that governs those decisions didn’t begin with humans. So we see monkeys making the same kinds of classic mistakes that humans make, like “loss aversion,” where we work harder to avoid losses than to achieve equivalent gains. (<a href="http://www.ted.com/talks/laurie_santos.html">check out her TED talk </a>for a great explanation.)</p><p><img alt="(WBEZ/Gabriel Spitzer)" class="caption" src="http://llnw.wbez.org/blog/insert-image/2012-March/2012-03-20/THUMBNAIL_Gorrilla.png" style="width: 250px; height: 188px; margin: 10px; float: right;" title="(WBEZ/Gabriel Spitzer)">We’re also subject to the same quirks of biology as many non-human primates. Biologists have found that <a href="http://www.biologicalpsychiatryjournal.com/article/S0006-3223%2895%2900675-3/abstract">monkeys with high levels of testosterone and lower levels of the brain chemical serotonin </a>tend to take more risks: taking longer leaps between trees, challenging unfamiliar males, and so on. Maestripieri and his colleagues set up a <a href="http://insight.kellogg.northwestern.edu/index.php/Kellogg/article/the_biochemistry_of_financial_risk">similar experiment with business school students. </a>There too, those with higher levels of testosterone were more likely to make long-shot investments or go into a riskier profession.</p><p>Finally, we check in with neuroeconomist <a href="http://www.kellogg.northwestern.edu/faculty/kuhnen/htm/">Camelia Kuhnen </a>of Northwestern University. She finds that our investment decisions are heavily influenced by some of the most ancient parts of our brains.

If the resolution passes, it would make Chicago the first city in the U.S. to oppose all forms of torture. Local residents Mario Venagas, a Chilean torture survivor, and Dr. Frank Summers, a psychologist, discuss why this resolution matters. Later, <em>Worldview</em> takes you inside the film <a href="http://www.beneaththeblindfold.org/Home.html" target="_blank"><em>Beneath the Blindfold</em></a> with directors Ines Sommer and Kathy Berger. The film follows four survivors of political torture as they try to overcome the lasting effects of their imprisonment and reclaim their dignity. It premieres this Friday at the <a href="http://www.siskelfilmcenter.org/strangerthanfiction2012" target="_blank">Gene Siskel Film Center</a>.</p></p> Tue, 10 Jan 2012 15:34:00 -0600 http://www.wbez.org/episode/worldview-11012 Clever Apes #23: First memories http://www.wbez.org/blog/clever-apes/2011-12-13/clever-apes-23-first-memories-94877 <img typeof="foaf:Image" src="http://llnw.wbez.org//blog/photo/2011-December/2011-12-13/Gabe trike for web.jpg" alt="" /><p><p><img alt="Each time we recall a childhood memory, we're rewriting it.

(WBEZ/Gabriel Spitzer)">I’m sitting at a picnic table in our screened-in porch. It’s my third birthday party, and I’m opening presents. I unwrap a Tonka truck, and drop to the floor to start playing with it.</p><p>That’s been my earliest memory ever since I can, well, remember. But as the years wore on, something weird started happening. I started to feel less attached to the person in that memory. Now, I feel like I’m seeing the memory through someone else’s eyes, watching myself push that truck on the green astroturf carpet. I’m not even sure it’s a real memory anymore.</p><p>This has been on my mind because my own son recently had his third birthday. It got me wondering what his first memory will be, and more broadly, what is the nature of early memories? How reliable might they be, and how important to the construction of our identities?</p><p>On the latest installment of Clever Apes, we dig into what science has to say about early memory. Young kids actually have lots of memories that don’t make it into long-term storage. The phenomenon, called <a href="http://www.psychologytoday.com/blog/the-child-in-time/201012/the-shifting-boundary-childhood-amnesia">“childhood amnesia,” </a>is not very well understood. But it seems to have something to do with the lens through which we see the world, and how it changes from early childhood (say, age three) to the more verbal period starting around age five or six. It’s tough to bridge that divide, and that may explain why I’m having a hard time connecting with my three-year old self.</p><p>And there’s another reason: memories are made from networks of neurons in our brains. That wiring gets used for lots of things, and so with each new memory, the networks change a little. When we remember something, we effectively rewrite it. That means that in some sense, each time we reflect on a memory, we’re putting a little more distance between ourselves and the actual event. Recent research suggests we’re even doing this in our sleep.</p><p>It’s enough to give a fellow a dose of existential distress. But there’s an upside too: A Chicago researcher has demonstrated <a href="http://www.luc.edu/childrensmemory/elaborative_conversation.shtml">ways that parents can reinforce and help solidify a child’s memories. </a>If you listen to the show, you can hear me trying this out on my son, Ezra. I bribed him with M&amp;Ms to get him to sit still.</p><p>Watch this space in the next day or so for a collection of first memories from our colleagues here at WBEZ.

Lianne Kurina of the University of Chicago and her team <a href="http://www.journalsleep.org/ViewAbstract.aspx?pid=28332">tested the theory that poorer sleep </a>might be what predisposes lonely people to high blood pressure, heart disease and even earlier death.</p><p>The researchers examined 95 people from a close-knit religious community in South Dakota centered around farming. The subjects did interviews, and then wore a special sensor called a wrist actigraph for a week to measure their sleep.</p><p>“Our study population in general was not very lonely” says Kurina, an assistant professor of health studies at the University of Chicago. “So it was surprising to find that even subtle differences seemed to translate into differences in sleep patterns.”</p><p>Specifically, the lonelier subjects slept just as long, but tossed and turned more and had more frequent wakings. The subjects did not seem aware of the difference in sleep quality, as there was no difference in the subjective reports people gave of their sleep.</p><p>The results match up with an earlier study of college students, a much more diverse group with widely varying senses of loneliness. Kurina says the consistency of results across these two very different groups suggests it might be a wide-reaching effect. The authors of the study, which appears in <a href="http://www.journalsleep.org/">the journal Sleep, </a>speculate it might have to do with a basic need to feel connected and secure in order to sleep soundly.</p></p> Tue, 01 Nov 2011 01:40:00 -0500 http://www.wbez.org/story/scientists-link-loneliness-lousy-sleep-93650 Why we love guns in the movies http://www.wbez.org/episode-segments/2011-08-02/why-we-love-guns-movies-89991 <img typeof="foaf:Image" src="http://llnw.wbez.org//segment/photo/2011-August/2011-08-02/milos guns.jpg" alt="" /><p><p>I tried to remember the first time I saw guns in the movies, but I couldn't do it. It's like guns have ALWAYS been there. Guns and shootouts were there as early as Edwin S. Porter's 1905 early classic film, "The Great Train Robbery”— a primitive, though brilliant precursor to the Western genre. The American Western subsequently rationalized the genocide of American Indians by elevating the image of technologically superior white men with guns — which made them such efficient killers — over the image of the so-called savages who used bows and arrows. One might as well ask, what is it exactly that the white defenders of the Empire are so actively defending in so many movies? What requires so much wholesale gun-induced bloodshed, usually of people who are NOT like the heroes in race, character, ethnicity, physical appearance, or political philosophy?</p><p>Did this inherent presence of guns in movies influence my attitude to violence? Perhaps - I hate gratuitous violence in film - and movie violence is very often gratuitous. I just don't want to watch it. I realize many others have the opposite reaction. Watching kids with their eyes -- and one assumes their minds -- glued to violent video games, I can only assume they've made the transition to an alternate universe where guns don't really hurt real people, and a gun shot is just an additional shot of adrenalin in the pulse of youthful excitement.</p><p>For me, the most memorable movie gun moments don't involve a strutting John Wayne or, for that matter, Gary Cooper poised in some dusty pseudo-Western courtyard with an itchy trigger finger. What impacts me are the moments when guns are most abstract, as in the strange demolition of scorpions that is the prequel of Sam Peckinpah's "Wild Bunch," or in the Coen Brothers' first feature, "Blood Simple," in which gun violence is part of the cartoonish parade -- ironic at every turn and gesture. This applies, too, to the early Quentin Tarantino movies like "Pulp Fiction" and to some of the Hong Kong action films to which it owed its provenance, in which guns become instruments of a balletic fantasy in which they might as well be pencils. The Takeshi Kitano films like "Violent Cop" are in this genre, too, but knowingly or unknowingly, they owe a lot to Sam Peckinpah, who took film to violent extremes, but intelligently, with an underpin to the ironic in a very cynical spin. Peckinpah’s statement was that violence was an innate part of man's nature, and there wasn't much to rationalize about it — like in Hollywood Westerns, in their simplistic fairy tales of good versus evil.</p><p>Guns in movies used to be exclusively reserved for testosterone-driven male characters until sometime in the 1980s when films like "La Femme Nikita" and the newer James Bond films introduced sexy women who could aim and fire with split second timing. Calendars featuring scantily-clad women with bazookas followed soon after.</p><p>This all leads me to my favorite gun imagery in film. The scene is repeated several times in the course of Dusan Makavejev's pseudo-documentary, "WR: Mysteries of the Organism." Dressed as a soldier, Tuli Kupferberg, the anarchist, poet, and co-founder of the band The Fugs, walks around Manhattan toting a toy rifle. He ends up stalking people at Lincoln Center, as he gleefully masturbated his toy rifle.</p><p>In a brief gesturee — a kind of interlude — Makavejev breaks down to its psychological essence what guns are really all about: fear and power. In the context of psychoanalyst Wilhelm Reich, which Makavejev's film is theoretically about, guns are part of a sexually repressive authoritarian structure leading to war, dictatorships, rapes and murders-- a sick society which refuses to be made whole. In Makavejev's world, we must collectively make love, not war, because guns and violence are loved by those individuals interested in pleasuring only themselves.</p><p>In films, conflict is essential to a film's dramatic arc. But gun violence as the centerpiece of so much film seems like an expedient means of gaining command of a maximum number of eyeballs. Every filmmaker has a choice. The smart and transcendent ones, like the arch audience manipulator, Alfred Hitchcock, know that the suggestion of violence is a mechanism more powerful and enduring than a hundred thousand bullets from an automatic...</p><p><em><a href="../../contributor/milos-stehlik" target="_blank">Milos Stehlik’s</a> commentaries&nbsp;reflect his own views and not necessarily those of Facets Multimedia, <a href="http://www.wbez.org/worldview" target="_blank">Worldview</a> or 91.5 WBEZ. </em></p></p> Tue, 02 Aug 2011 17:33:00 -0500 http://www.wbez.org/episode-segments/2011-08-02/why-we-love-guns-movies-89991
