dmunger | April 13, 2009One of the most controversial topics here on Cognitive Daily is whether playing video games can lead to aggressive behavior or violence -- and one of the most dramatic demonstrations of the impact of violent video games was a 2000 study by Craig Anderson and Karen Dill. In that study, participants played violent or non-violent games, and then were asked to play another "game," this time against what they believed was a real person in a nearby room. In fact, there was no human opponent, and the game was rigged so that the player "won" half the time. The gamers were wearing headphones, and…
dmunger | April 8, 2009The Mafa people, who live in the far north of Cameroon in the Mandara mountains, are one of the most culturally isolated groups in the world. Since many of their settlements lack electricity, there are some individuals who have never been exposed to western movies, art, or music.
But the Mafa do have their own musical tradition. Many of their ceremonies are accompanied by a unique chorus of flutes of varying sizes, which can produce different pitches by covering and uncovering a small hole at their tip. The music they produce is quite different from Western-style music. Here's a sample:…

Do people ever tell you to "just smile, you'll feel better"? If you're like our daughter Nora, you hear it a lot, and you get annoyed every time you hear it. Telling a teenager to smile is probably one of the best ways to ensure she won't smile for the next several hours. But the notion that "smiling will make you feel better" has actually been confirmed by research. There are several studies demonstrating that people are happier when they smile, at least in certain circumstances.
It's not as easy as you might think to study the effect. For one thing, it'…
edyong | March 25, 2009We're used to thinking of neglect as a lack of appropriate care, but to a neuroscientist, it has a very different meaning. "Spatial neglect" is a neurological condition caused by damage to one half of the brain (usually the right), where patients find it difficult to pay attention to one half of their visual space (usually the left).
This bias can affect their mental images too. If neglect patients are asked to draw clocks, many only include the numbers from 12 to 6, while some shunt all the numbers to the right side. When two famous neglect patients were asked to describe a familiar square…
dmunger | March 18, 2009Take a look at these two pictures of the Mona Lisa:
They're derived from a series of images of the famous painting that had been obscured by random noise filters (like when your old analog TV wasn't getting a signal), like this:
Each picture appears to have a slightly different facial expression -- some happier, some sadder, depending on the random alteration of the image due to the visual noise. The two color pictures above are composites, made by picking the saddest (for picture B) and happiest (picture C) from over a hundred random images -- rated by 12 volunteers -- and combining them…
dmunger | March 4, 2009 What's your first reaction on seeing this picture of Nora? Are you excited because she appears to be excited? Or do you react to her intent? Perhaps you think she's cute, or maybe even sarcastic. Ultimately you might have all of those reactions.
There's no doubt we're exceptionally fast at responding to faces, and to the emotions they convey. But reacting appropriately, especially when a face signals danger, could be the difference between life and death.
These two ways of reacting to a facial expression correspond to two possible intentions of an expression: to elicit an emotion in someone…
thusspakezuska | February 24, 2009As a graduate student, I observed the nascent field of functional magnetic resonance imaging and thought to myself with some amusement "modern phrenology! Now with big, fancy, expensive equipment!" Count me among those who have never been terribly impressed with fMRI, and certainly not with its applications in what is known as social neuroscience.
Now we have this:
Late last year, Ed Vul, a graduate student at MIT working with neuroscientist Nancy Kanwisher and UCSD psychologist Hal Pashler, prereleased "Voodoo Correlations in Social Neuroscience" on his website. The journal Perspectives…
edyong | February 16, 2009The wiping of unwanted memories is a common staple of science-fiction and if you believe this weekend's headlines, you might think that the prospect has just become a reality. The Press Association said that a "drug helps erase fearful memories", while the ever-hyperbolic Daily Mail talked about a "pill to erase bad memories". The comparisons to The Eternal Sunshine of the Spotless Mind were inevitable, but the actual study, while fascinating and important, isn't quite the mind-wiper these headlines might have you believe.
The drug in question is propranolol, commonly used to treat high…
dmunger | February 9, 2009One of stand-up comic George Carlin's most famous routines was the seven words you can't say on TV (obviously, not safe for work). He repeated the words over and over, and it was hilarious -- especially back in the days before most people had cable. These days we've become desensitized to those words, and it's hardly surprising any more to see them laced into casual conversation.
Or is it?
One test of our ability to ignore words is rapid serial visual presentation, or RSVP. In RSVP, you're shown a rapid sequence of words or images -- one about every tenth of a second. Your job is to pick out…
dmunger | October 20, 2008You're given $15. Which of these bets would you gamble your $15 on?
An 80 percent chance of winning $18.75
A 40 percent chance of winning $37.50
A 20 percent chance of winning $75
A 5 percent chance of $300
Or would you just keep the original $15?
The answer, it turns out, depends on your emotional state -- and your gender. We've discussed before how emotion can affect risk-taking: Fearful people, for example, tend to be less willing to take risks, while angry people seem more willing to. But what if the same emotion led to different risk reactions in different people?
It might actually…
dmunger | October 16, 2008Ben and Bernice Finn have been married for 60 years. And they still remember their first date.
"I was very nervous," Ben said. "She was so pretty."
"I remember that day very well," Bernice said. "And no, you weren't pretty."
But when the couples all went out that night, there was a chill in the air.
"And I took your arm," Bernice said.
"I was thrilled by that," Ben said.
"And the reason I took your arm is, you seemed nervous. And I wanted to make you more comfortable."
It's a heartwarming story, and I encourage you to listen to the whole thing. Don't worry, we'll wait for you. When you get…
dmunger | October 14, 2008Yesterday we tried to replicate the effect that John Eastwood, Daniel Smilek, and Philip Merikle observed -- that negative facial expressions distract us from even the simplest tasks more than positive facial expressions. Hundreds of our readers watched one of two videos and were charged with counting the number of "upturned arcs" or "downturned arcs." Here's a sample video:
In this video, the "faces" formed by the arcs are smiling, but in the other video they were frowning. Both clips showed the identical number of upturned and downturned arcs -- six. Yet we weren't able to replicate…
dmunger | October 2, 2008You're at a bar, club, or church social and you've just met an absolutely stunning member of the opposite sex. You're single and available, and you detect no signs of romantic commitment in your new conversation-partner. Could he/she be interested in you too?
Or you're walking down a poorly-lit street in an unfamiliar city. It's 11:30 p.m., you're alone, and there are no signs of activity other than the occasional passing car. Suddenly you notice a large man emerge from an alleyway ahead of you and stride purposely in your direction. Is he a threat?
In situations such as these, you'd probably…
dmunger | September 29, 2008Thomas Levenson has written an interesting post about John McCain and his fascination with high-stakes gambling. While it's clear that his gambling habit isn't going to put McCain in any serious financial danger, it does raise questions about his personality. One of the most difficult things voters try to do in an election is to predict the candidate's future behavior. We know what the candidates have done in the past, but how they'll respond in future crises is what will matter most if they are elected.
If a new crisis emerges, will the new president take risks, or play it safe? One test…
dmunger | September 15, 2008It's now taken as a given that the musical score of a movie can have huge influence on our perception of the movie. From the pulsating terror achieved in films like Psycho and Jaws, to the triumphant victories in Star Wars and Pirates of the Caribbean, it's hard to think about a great film without also being influenced by that film's score. Music is such an important aspect of film that when a group of students was asked to rate the emotions evoked by music in six film excerpts, only a third of them noticed that all the film clips had no music. This was on a multiple choice test, where the…

As parents of a 1516-year-old, Greta and I are very interested in what causes people to behave aggressively. We know a lot about specific causes of aggression -- violent media, testosterone, guns, and personal insults can all lead to aggressive behavior in certain circumstances. But kids and others exposed to one or more of these things don't necessarily become violent. Sometimes it seems that just the presence of his sister in the room can cause Jim to act more aggressively than he would otherwise.
That's one reason we were intrigued…

There is a considerable body of research showing that eye contact is a key component of social interaction. Not only are people more aroused when they are looked at directly, but if you consistently look at the person you speak to, you will have much more social influence over that person than you would if you averted your gaze.
The problem arises when you address a group of people. How do you pick who to engage visually? Most public speakers are encouraged to look around the room, alternating eye contact with individuals in the audience…
dmunger | April 17, 2008If you saw a headline like this one in your local newspaper, you might first think it's some type of info-tisement sponsored by the floral industry. You'd probably be right, too. So what is this headline doing in Cognitive Daily? We've found a study to support the notion that flowers actually induce real positive emotions.
Was it paid for by the floral industry? Yes, it was. Does that mean it's bad research? Not necessarily. A team led by Jeannette Haviliand-Jones has conducted an impressive set of three experiments, each of which contributes to the idea that giving someone flowers improves…
dmunger | April 14, 2008How often do you take time to reflect on the things you're grateful for? Once a month? Once a week, at church, perhaps? Maybe you say "grace" at mealtime every day. But even prayers that do express gratefulness, such as a traditional mealtime prayer, are often expressed by rote. Growing up, my family wasn't very religious, but when we had dinner with family or friends, we'd usually say grace. I was probably well into my teens before I understood what "blessusolordforthesethygiftswhichweareabouttoreceivefromthybounty" actually meant.
While many would agree that "counting your blessings" is a…
dmunger | December 27, 2007Earlier this week we discussed the relationship between life satisfaction and other measures of well-being, finding that for measures such as relative income, the happiest people weren't always the best-off. For relationships, however, the happiest individuals also seem to do better.
But these measures were only taken at an instant in time. What about over longer periods? The College and Beyond study questioned incoming college freshmen in 1976, and included a self-rating of "cheerfulness," among many other measures. Then those same individuals were surveyed in 1995. How did cheerfulness…
