dmunger | March 21, 2006What's the best way to ensure that law enforcement officers don't abuse their authority and coerce innocent suspects into confessing? Yesterday we discussed research suggesting that a side-view videotape of a confession was more likely than a head-on view to result in an accurate assessment of whether that confession was voluntary or coerced.
But the Lassiter team's study was still open to some key criticisms. First, the study participants were all college students -- certainly not a typical jury demographic. Second, jurors don't see videotaped confessions in isolation -- when a confession is…
dmunger | March 20, 2006College student Bradley Page dropped his girlfriend off in a park one evening, only to learn later that she had been murdered and buried in a shallow grave. Police investigating the death interviewed him about the incident, repeatedly asking him why he could have left her alone in that park. "It was the biggest mistake of my life," he responded in anguish. Eventually, the officers told him that witnesses had seen him near where the body was buried and that his fingerprints had been found on the murder weapon. These statements astonished Page, who hadn't even remembered leaving his apartment.…
dmunger | March 16, 2006A Witches' Bible states that "the sensitive is psychically aware of character qualities, or emotional or spiritual states, in the subject, and this awareness presents itself to him or her as visual phenomena." It's easy to dismiss such claims as pseudoscientific claptrap, yet there exist humans who, when presented with nonvisual stimuli such as tastes or smells, perceive visual imagery. I'm talking about the scientifically recognized condition, synesthesia. Synesthetes are people who perceive stimuli presented in one mode (often corresponding to one of the five senses) with a different mode.…
dmunger | March 14, 2006If my twentieth high school reunion last year was any indication, we seem to hang on to the music we listened to as adolescents longer than any other time period. Everyone was dancing to "Purple Rain" and "Rock Lobster" like the music written in 1984 was the best ever written. A 1996 study confirmed this notion, finding that young adults express stronger preference ratings for music than older adults.
Take a look at a random sampling of accounts on MySpace, and you'll see that nearly every member has a song associated with his or her account. It's as if music somehow forms part of a person's…
dmunger | March 7, 2006The Prisoner's Dilemma is an ethical conundrum that's been used for years by psychologists, economists, and philosophers to explore human behavior. The basic scenario is this: two criminals have been captured and placed in separate cells. Neither prisoner is allowed to talk to the other, and the interrogators don't have enough evidence to prosecute either one. If prisoner A confesses and prisoner B doesn't, then prisoner A is released and prisoner B gets punished. If both confess, then both will get a lighter sentence. If neither confesses, then both will be released. For each prisoner,…
gmunger | March 1, 2006We've reported on a variety of different studies looking video games and various measures of aggression (you can check out our "Video Games / Technology" category, and our archives) and a fairly common reaction, often coming from an avid gamer, is that this simply isn't true about him. Now one of the serious complications of doing psychological research is that our intuitions about how, or even what, we are doing can be dramatically wrong--this is why psychologists started doing experiments some one hundred and twenty odd years ago. You cannot refute a careful experiment with a personal…
dmunger | February 23, 2006Since yesterday's post on attention grabbed so much, well, attention, let's try another one. Only this time, instead of looking at what factors cause us to pay attention to something, we'll consider an experiment that studied the emotional effects of attention. If you're asked to look for people with blond hair, for example, you may eventually come to have a different emotional response to people with blond hair than others.
A team led by Mark Fenske developed a simple procedure to see if the focus of our attention can affect emotion. Twenty-four college students participated in a task that…
dmunger | February 13, 2006The TV movie Flight 93, which re-enacted the hijacking of a United Airlines flight on September 11, 2001, was criticized because it "humanized" the hijackers (despite this apparent humanity of their captors, the movie did portray the passengers and crew on that flight fighting back and eventually causing the plane to crash in a sparse Pennsylvania woodland instead of a crowded city). The critics' argument was simple: why portray the hijackers, clearly bent on destroying as much life as possible, as anything but vile murderers?
The obvious reply: can't we, as thinking human beings, overcome…
dmunger | February 8, 2006One of the first questions our son Jim asks when a new movie comes out is "what's it rated?" The more "adult" the rating, the more appealing the movie is to him: PG is the lowest rating he'll even consider, PG-13 is better, and R is best. Since he's only 14, we don't take him to many R-rated movies, which is possibly what adds to their appeal.
But even PG-rated movies and TV shows still display an abundance of violence, and plenty of parents are happy to let their kids watch violent programming, especially if there isn't any sex involved. We've reported on a lot of media violence studies on…
dmunger | February 6, 2006In 1973, a massive study of almost 400,000 Dutch men appeared to confirm what anecdotal evidence and even some scientific research had led scholars to suspect: The first-born child in a family tends to be the most intelligent. The researchers, Lillian Belmont and Francis Marolla, found that within a given family size, earlier-born children tended to have slightly higher IQs than later-born children, even after controlling for social class. Their study pool was the entire population of 19-year-old men in the Netherlands.
Since then, researchers have developed all sorts of models to try to…
dmunger | February 2, 2006Twelve years ago, Greta and I were awakened by a rattling on the door of our Bronx apartment. It was about three A.M.; our children were asleep in the next room. "What should I do?" Greta whispered to me. She had woken first and was holding the deadbolt on the door locked so the intruder couldn't get in.
"Call the police," I whispered, and took hold of the lock. I ventured a peek through our peephole. I could see only the grizzled razor stubble of a man who was clearly shorter than I was. He continued to struggle with the door. He was making progress picking our lock -- I had to forcefully…
dmunger | February 1, 2006My son Jim's favorite game, World of Warcraft, only works on my computer, which usually resides in the kitchen. Inevitably, Jim's often playing his game while Greta and I are making dinner, and I have to say, the most annoying thing about the game isn't the violence or the sound effects -- it's the background music. We're constantly asking him to turn the volume down so we don't have to listen to that dull, repetitive music.
So don't gamers find music annoying, too? I know when I'm indulging in my one guilty pleasure -- computer golf -- the room must be absolutely silent. Music is the worst,…
dmunger | January 25, 2006 Disney's purchase of Pixar makes it clear that computer-generated (CGI) animation appears to be the wave of the future in movies. But one difficulty with CGI animation is conveying realistic emotions. While film animators (whether they use computers or not) can use artistic license to achieve the desired effects, when "emotions" are generated exclusively by computer, it can be difficult to identify the key factors in conveying that emotion.
We've discussed avatars, for example, as one way that computers can automate human interaction. Artificial intelligence -- lifelike simulators of human…
dmunger | January 19, 2006To say college students* aren't well-known for their efficient sleep habits might be the most dramatic understatement since Washington observed that Valley Forge winters are "a bit nippy." I can remember dozing off with my head in a pile of books at the library when I was in college, then waking with "The Riverside Chaucer" imprinted on my face in mirror-image.
Undaunted by college students' reputation for irregular sleep, a group of researchers conducted a large study of Ohio State University students' sleeping habits. Among the many questions they attempted to answer was a simple one: how…
dmunger | January 17, 2006Point-light displays can tell us an amazing amount about other people. Looking only at a few glowing spots corresponding to joints and set in motion, we can tell what people are doing, whether they are over- or underweight, and even identify a friend among strangers. We can also identify animals or determine the emotional state a dancer or actor is conveying. But some emotions are more difficult than others. Take a look at the following two animations (click on the image to view a quicktime movie):
Now, which emotion does each animation convey? Your choices are Anger, Joy, Sadness, Love,…
dmunger | January 10, 2006The Flying Spaghetti Monster (source: verganza.org) is a satirical retort to advocates of "intelligent design," created as a joke to mock the belief that some "intelligent designer" created life. While the Flying Spaghetti Monster is funny, no one takes it seriously. Meanwhile, belief in a Christian God is stronger than ever, and advocates of the theory of evolution are unshaking in their support.
So what's the difference? Why do people hold some beliefs strongly, but readily discard others? Jesse Preston and Nicholas Epley have designed a technique to examine the types of evidence people…
sb admin | January 6, 2006My son Jim loved his bottle when he was a baby. By about 15 months of age, he loved baby formula so much that he was going through over a hundred dollars' worth a week -- more than the rest of the food budget for the entire family! (Yes, we were buying the powdered stuff, not pre-made formula.) There were weeks when we completely exhausted the local grocery store's supply.
Needless to say, soon his pediatrician pointed out he was gaining weight too quickly, and we should cut his rations down to, say, three bottles a day. It was a painful transition. Previously, all Jim would have to do was…
dmunger | December 26, 2005How do we know when we see a beautiful body? Is it some social standard such as thinness or proportion? Do we simply think that bodies that are closest to "normal" are also most beautiful? We know that to be the case with faces, where faces that closest to "average" are generally rated as more attractive than others which deviate, and faces that combine the characteristics of several races are rated as more attractive than those typical of a particular race.
We've written before on how our perception of faces can be altered. If you look at faces that have been systematically distorted to look…
dmunger | December 21, 2005There is little doubt that the cognitive demands of conversation can affect our awareness of the world around us. Everyone has a story of a near-miss collision with some clueless airhead driving who was jabbering away on the cell phone. A co-worker once tearfully told me of the time she was in an argument with her boyfriend while parked in his car at the side of the road. Furious, he got out of the car and slammed the door. He never noticed the passing car that hit him and instantly killed him. Was this a freak accident, or does conversation—and not just cell phone conversation—impair our…
dmunger | December 19, 2005We learned from Alas, a Blog that Henry Jenkins has written an essay for PBS about video games, making the case that the public doesn't understand what the games are all about. Normally articles here on Cognitive Daily only report on peer-reviewed research, but in this case, we felt it was important to make an exception. We feel that Jenkins makes some misleading statements in his essay, and we'd like to take this opportunity to point our readers to some research showing why this is so.
I've used indented quotations to give snippets from Jenkins' argument; my responses are in normal text.…
