Booming world population doesn’t mean growth everywhere
by Dave in The Daily Monthly
Population changes don’t affect all nations equally at once. While population in some countries is increasing rapidly, in others it’s slowing or even declining. Take a look at the case of Japan and Nigeria:
Currently Nigeria and Japan have nearly equal populations, but in [...]... Read more »

How can we predict world population growth?
by Dave in The Daily Monthly
Predicting the future is always difficult. Who could have known in the year 1775 that 100 years from then, ships and trains powered by coal would allow people to circle the earth in weeks rather than years? Who could have predicted that in another 100 years, the human voice—and moving images—would be able travel that [...]... Read more »

How close are we to a cure for HIV / AIDS?
by Dave in The Daily Monthly
When I began work on this month’s project, I contacted a clinician, a case manager, and a scientist to get their perspectives on how we’re making progress fighting HIV and AIDS. I’ve introduced you to the clinician and the case manager, but not the scientist.

Study reveals importance of adhering to the drug regimen for AIDS patients
by Dave in The Daily Monthly
Yesterday I mentioned that a key aspect of fighting AIDS is staying on the drug regimen. Charles pointed out that this is more difficult than it might seem: the drugs are constant reminder of your condition, and taking them can revive horrible memories.
But how important is it to maintain adherence to the regimen? A 2008 [...]... Read more »

Synesthesia and the McGurk effect
by Dave Munger in Cognitive Daily
We've discussed synesthesia many times before on Cognitive Daily -- it's the seemingly bizarre phenomenon when one stimulus (e.g. a sight or a sound) is experienced in multiple modalities (e.g. taste, vision, or colors). For example, a person might experience a particular smell whenever a given word or letter is seen or heard. Sometimes particular faces are associated with specific colors or auras. Synesthesia is relatively rare, but the people who experience it are genuine: their perceptions ar........ Read more »

Does watching TV really kill you?
by Dave Munger in Cognitive Daily
Today I had to put off my normal morning run in order to make time to be interviewed on a radio show at 7:30 a.m. As I waited on hold for the interview to start, I could hear the hosts joking back-and-forth about what the "latest TV controversy" is. "Is it the Jay Leno / Conan O'Brien news on NBC?" the host asked? No. Then the hosts rattled through several other hot-button issues on television before arriving at this: "New research from the American Heart Association Journal [Circulation] sugges........

The outfielder problem: The psychology behind catching fly balls
by Dave Munger in Cognitive Daily
It's football season in America: The NFL playoffs are about to start, and tonight, the elected / computer-ranked top college team will be determined. What better time than now to think about ... baseball! Baseball players, unlike most football players, must solve one of the most complicated perceptual puzzles in sports: how to predict the path of a moving target obeying the laws of physics, and move to intercept it.
The question of how a baseball player knows where to run in order to catch a f........ Read more »

Is there an easier way to detect lies than what you see on TV?
by Dave Munger in Cognitive Daily
The TV show Lie To Me focuses on the exploits of an expert in lie-detection as he solves perplexing crimes in his high-tech Washington laboratory. It's actually fun to watch, especially since it appears to make some effort to get the science right (a real-life expert on lie-detection, Paul Ekman, serves as a science adviser on the show).
One of the show's premises is that only highly-trained experts (most importantly, its protagonist, Cal Lightman) are capable of sniffing out a well-schooled l........ Read more »

How many slices does it take to accurately judge personality and intelligence?
by Dave Munger in Cognitive Daily
Suppose your organization is interviewing candidates for an important job. Would it be better for one trusted person to have an extended interview with them, or for several people to talk to them for less time? How many people would you need to conduct the interviews? Would three be enough? Would ten be too many? If ten is good, wouldn't twenty be even better?
We've discussed thin-slicing studies before -- the idea that a few brief exposures to an individual can give just as accurate an impress........ Read more »

ResearchBlogging.org and PLoS work together to measure the impact of journal articles
by Dave Munger in ResearchBlogging.org News
With over 800,000 journal articles published in 2008 alone, it’s impossible even for experts to read all the peer-reviewed research published in their fields. So how do they choose which articles to read? How do non-experts decide which articles are the most important? Until recently, there really wasn’t an effective way to assess the importance [...]...

Emotional words distract, but only when you're searching for meaning
by Dave Munger in Cognitive Daily
I attended an unusual middle school. It was designed on an "open concept," with the idea that there should be no walls between classrooms. Social pressure would keep the noise levels down, because if kids got too loud, then their peers in other classes would encourage them to hush up. This actually worked most of the time, but one day one of the English teacher's classes was getting out of hand, and after trying several ways to get their attention, she resorted to something a big more dramatic. ........

People identify the sexual orientation of strangers as fast as 50 milliseconds
by Dave Munger in Cognitive Daily
Nalini Ambady has become famous for her research on "thin slicing," the idea that ordinary people can make accurate judgments about others amazingly quickly. We've discussed work from her lab showing that people can accurately predict teaching ability by watching just six seconds of video of a teacher at work. Other judgments, like gender, race, and age, can be made even faster.
But what about less obvious traits? Nicholas Rule and Ambady designed a study to see if college students could accura........ Read more »

What if you saw something that rocked your world ... and you didn't notice?
by Dave Munger in Cognitive Daily
If you're a regular reader of Cognitive Daily, you're relatively accustomed to seeing surprising things. Indeed, it's gotten to the point where you might even expect it. You've seen optical illusions and videos that baffle the imagination. Yet most participants in psychology research studies aren't aware of the many ways the mind can be "tricked." One of the most dramatic tricks, which we've discussed several times, is the phenomenon of Change Blindness. A........ Read more »

What your Facebook page says about who you "really" are
by Dave Munger in Cognitive Daily
Recently a woman had her sick leave benefits based on a diagnosis of clinical depression terminated because of a few pictures she posted on her Facebook page showing her smiling at a birthday party and enjoying a trip to the beach. Was this a fair assessment of her medical condition? Probably not--people with clinical depression can have moments of genuine joy or elation, and even sad people can fake a smile for a photo.
But regardless of whether a few photos posted online are sufficient eviden........ Read more »

Detecting faces: People use some of the same strategies computers do
by Dave Munger in Cognitive Daily
How does our visual system decide if something is a face? Some automated face-detecting software uses color as one cue that something is a face. For example Apple's iPhoto has no trouble determining that there are two faces in this color picture:
That's Nora in the back, and her cousin Ginger in front. In this picture, however, iPhoto can't identify a face:
That's a vintage black-and-white photo of Nora and Ginger's grandfather, but the computer can't find any faces in it. Do people, like ........ Read more »

Men often treat their friends better than women do
by Dave Munger in Cognitive Daily
Who's more "sociable," men or women? Common sense says it's women, right? And many research studies back this impression up: Women are more interpersonal, more connected, more interdependent than men. Women are more likely to share intimate information with each other than men. But is that really the whole story?
There is also research suggesting that men have larger social networks than women do, and that male-male friendships last longer than female-female ones.

The long-term effects of day-care
by Dave Munger in Cognitive Daily
When we were getting ready to have our first child, I decided that I would quit my job, work out of home as a freelancer, and take care of our baby while Greta finished graduate school.
That worked well for about two years, but by the time Nora was born, we decided to hire a part-time nanny so I could finish a degree of my own. When Nora was one and Greta and I were starting new jobs in a new state, both kids entered full-time day care, and that was our child-care arrangement until they starte........ Read more »

Do chimps understand what Jon Stewart (or another chimp) believes?
by Dave Munger in Cognitive Daily
Take a look at this video from last night's episode of Jon Stewart's "The Daily Show."
If you'd like, you can skip past all the political snark to the 4:47 mark to watch Jon bring cognitive psychology into prime time (or at least latenight cable)! That's right; you saw it: Jon Stewart mentioned the psychological concept of "object permanence" on national TV. Object permanence was introduced by Jean Piaget as a way of measuring the growing cognitive ability of children. Three-month-olds don't ........ Read more »

What's the best way to take a study break?
by Dave Munger in Cognitive Daily
Greta and I did our undergraduate studies at the University of Chicago, or as a commonly-sold T-shirt on campus put it, "where fun goes to die." To say that Chicago didn't emphasize academics over a social life is to deny that people literally lived in the library (a full-scale campsite was found behind one of the stairwells in the stacks; students had been living there for months). It's not that the administration didn't try to encourage its students to socialize. The library did close at 10 p......... Read more »

Anime film characters: Do we perceive the intended race, or our own?
by Dave Munger in Cognitive Daily
One of my favorite cartoons as a child was "Speed Racer." It featured an all-American boy (first name, "Speed," last name, "Racer") engaging in that most American of pastimes: driving fast cars. Except that "Speed Racer" wasn't really American; it was made in Japan, and the original Japanese voices were crudely overdubbed in English. Perhaps I can be excused for not noticing the Japanese origins of the show -- I was only 10 years old. Even now, as an ........ Read more »
