100 Things You Should Know About People: #26 — Culture shapes our brains

My entire career I’ve been worried about the fact that most psychology research is conducted on 18-24 year old college students. What if the way 18-24 year old college students react, think, and behave is not the same as everyone else? We are drawing conclusions about PEOPLE in general, but only collecting data from a small subset of people whose brains are still changing. It seemed silly that there were rigorous rules about how to conduct scientific studies in psychology, and yet this basic premise about who was being researched and how applicable the research was to different people was ignored. It’s made me secretly skeptical about research. Which is ironic, since I spend a fair amount of time searching out research, thinking about it, interpreting it and writing about it. I guess some research is better than no research?

Does culture shape “basic” cognitive processes?– And now I’ve come across an entirely new reason to be skeptical about the theories we have about how the brain works — cultural effects. In his book, The Geography of Thought, Richard Nisbitt discusses research that shows that how we think — our cognitive processes — are influenced and shaped by culture. For example, if you show people from “the West” (US, Europe) a picture, they focus on a main or dominant foreground object, while people from Asia pay more attention to context and background. Asian people who grow up in the West show the Western pattern, not the Asian pattern, showing that this is based on culture, not genetics.

Is most of our research in psychology based on what “westerners” think? — This has profound implications for some of the theories we have about cognitive processing. We have research about how people think, how many items can be stored in memory, etc. What if these theories about how people think are really theories about how Western people think and are not universal?

Do cultural differences show up in brain activity? — Sharon Begley recently wrote about this in Newsweek. She reports on recent neuroscience research that confirms the cultural effects. “… when shown complex, busy scenes, Asian-Americans and non-Asian–Americans recruited different brain regions. The Asians showed more activity in areas that process figure-ground relations—holistic context—while the Americans showed more activity in regions that recognize objects. To take one recent example, a region behind the forehead called the medial prefrontal cortex supposedly represents the self: it is active when we (“we” being the Americans in the study) think of our own identity and traits. But with Chinese volunteers, the results were strikingly different. The “me” circuit hummed not only when they thought whether a particular adjective described themselves, but also when they considered whether it described their mother.”

Will it ever end? – This is the curse of research. Just when we think we know something, we find out there are more questions than answers!  One trend that should help is that there is more and more research coming out of Asia. If you peruse the psychology scientific journals you will see that more than half of the research that is being published today comes from Asia. Another big chunk comes from Europe, so the psychology research now is not so US centric. This will help, or will it? Will we now have to worry that the results from Asia don’t apply to the West? Should all psychology research be done using different cultures?

What do you think?

Who is The Most Romantic?: The Brain Science of Valentine’s Day

Posted in neuro web design, psychology, research on February 7th, 2010 by Susan Weinschenk – 4 Comments

Happy Valentine's DayIt’s almost Valentine’s Day and you go online to look for a gift to buy that special someone in your life. What will you buy? I posed that question to both men and women in a small research study I conducted recently. And the answers I got surprised me.

When research answers a different question than the one you meant to ask — Actually, the question I thought I was studying was about how much money people would be spending online. I had a theory that if people stated up front what their Valentine’s gift budget was, then they would be more likely to stick with that budget. So I ran two groups: people who were asked how much money they planned to spend before the shopping started, and people who weren’t. And I split both of those groups into men and women to see if there were any gender differences to the budget question.

The budget question was a bust — It turns out that when you ask people what their budget is, it doesn’t affect how much they buy at all, not men, not women. I saw the lack of a trend right away as I started analyzing the data, but then the data told me something totally different.

The gifts that men and women were buying were VERY different. Watch the video first, and then read on:

A disclaimer — This is not a formal research study with statistical analysis. It’s an exploratory study. Having said that, though, I was careful to present everyone with the same instructions, and I had people responding from all over the USA.

So here are the findings – Men picked traditionally romantic Valentine’s gifts, such as flowers, chocolate, and jewelry. Just about all the men picked these traditional gifts. The only slight deviation was one man who said he was buying tickets to dinner and a show. None of the women picked what would be considered a traditional Valentine’s gift. None. The women were purchasing: books, cell phones, pajamas, keychains, TVs….

Does this mean the men are more romantic? — Well, I guess it depends on what you call romantic. The men definitely mentioned love more than the women. The men would say things like:

100 Things You Should Know About People: #25 — Trust Your Gut or Be Logical? It Depends On Your Mood

In a previous post on how mood affects your reaction to brands you know (see You Are Most Affected By Brands And Logos When You Are Sad And Scared), I talked about the research from Marieke de Vries of Radboud University Nijmegen, in the Netherlands. De Vries also did research on two types of decision making: a trusting -your- gut intuitive method vs. following a logical, deliberative decision-making process of weighing alternatives and thinking through pros and cons. De Vries was interested in whether one method of decision-making was better than another, and also whether your mood affected the outcome of the decision.

When to use deliberative decision-making — Research by Dijksterhuis shows that when you have simple decision to make you make better decisions when you use a logical deliberative method.

When to use intuitive decision-making – Research by Shiv shows that when you have a complicated decision to make, you make better decisions when you use an intuitive or “gut” method.

100 Things You Should Know About People: #24 — You Are Most Affected By Brands and Logos When You Are Sad Or Scared

Here’s Scenario 1: You get together with your friends to watch your home team play a game on TV. They win! After an afternoon of fun and friendship you stop at a grocery store on your way home. You are in a good mood. Are you more or less likely to buy the usual cereal you always buy or will you try something new?

Here’s Scenario 2: It’s Friday afternoon and your boss calls you in to tell you that he’s not happy with your latest project report. This is the project that you repeatedly told him was in trouble and you asked that more staff be assigned. You feel all your warnings were ignored. Now he’s telling you that this work will reflect badly on you and you may even lose your job. On the way home you stop at the grocery store. You are sad and scared. Are you more or less likely to buy the usual cereal you always buy, or will you try something new?

You Want What’s Familiar – A series of research studies by Marieke de Vries of Radboud University Nijmegen, in the Netherlands, shows that when people are sad or scared, they want what is familiar. When people are in a happy mood they are not as sensitive to what is familiar, and are willing to try something new and different. read more »

100 Things You Should Know About People: #23 — You Are Hard-Wired For Imitation and Empathy

Posted in brain, research, stories on January 27th, 2010 by Susan Weinschenk – 6 Comments

Baby sticking out tongueIf you put your face right in front of a young baby and stick out your tongue, the baby will stick out his or her tongue too. This happens from a very young age (even as young as a one month old). So? What does this have to do with anything? It’s an example of the built-in, wired-into-our-brain capacity we have for imitation. Recent research on the brain shows how our imitative behavior happens.

Mirror neurons firing– In the front of the brain there is a section called the premotor cortex; motor as in movement. This is the part of the brain where you make plans to move. (It talks to the primary motor cortex which is the part of the brain that sends out the signals that actually make you move). So if you are holding an ice cream cone and you think about moving your arm to bring the ice cream cone up to your mouth, and then you do it, you can see first the premotor cortex lighting up and then the primary motor cortex lighting up. Neurons in the premotor cortex are firing — nothing surprising there. But here is where it gets interesting. If you watch someone else lift their arm and eat the ice cream cone a subset of the same neurons also fire. Just watching other people take an action causes some of the same neurons to fire as if you were actually moving. This subset of neurons have been dubbed, “mirror neurons”. We share these mirror neurons with other primates as well.

Who is taking action? — How does your brain know when you are taking the action vs. watching someone else take the action? After your mirror neurons fire from watching your friend take a lick of the ice cream cone, there is a feedback loop. Your brain registers that no ice cream was tasted, and therefore you know that you are watching someone eat ice cream, not that you just ate ice cream. read more »

Lottery ticketHere’s is a thought experiment – On a scale of 1 to 10, with 1 being the lowest and 10 being the highest, rate how happy you are right now. Write that number down. Now, I want you to imagine that today you win the lottery. You now have more money than you ever thought you would. You have millions and millions of dollars. At the end of today what would be your happiness rating? Write that number down. What about 2 years from now? What will be your happiness rating 2 years from now if today you win millions and millions in the lottery?

100 Things You Should Know About People: #20 — Your Attention Is Riveted By Pictures Of People

Posted in attention, brain, eye tracking, psychology, research, unconscious, visual design on December 24th, 2009 by Susan Weinschenk – 6 Comments

Picture of a baby looking right at the camera Second only to movement (animation, video), pictures of a human face capture attention in any medium, including websites. Pictures of a human face not only capture attention, but keep the attention on that part of the screen even when the picture goes away.

We start young — With some creative experiments it has been proven that babies as young as 4 months old will look at pictures of other people more than pictures of other objects or of animals. And this preference for faces continues throughout the life span. It seems to be part of our brain wiring.

The eyes have it – Research using eye tracking shows that when you show people a picture of the face of a person, their attention goes mostly to the eyes. If you want to capture someone’s attention at a website, showing a picture of a person who is looking right into the camera captures the most attention. read more »

100 Things You Should Know About People: #19 — It’s a Myth That All Capital Letters Are Inherently Harder to Read

Posted in eye tracking, psychology, reading, research, usability on December 23rd, 2009 by Susan Weinschenk – 8 Comments

WHAT YOU ARE ABOUT TO READ IN THE NEXT PARAGRAPH IS COMMONLY BELIEVED, BUT NOT TRUE – You read by recognizing the shapes of words and groups of words. Words that are in all capital letters all have the same shape: a rectangle of a certain size. This makes words displayed in all uppercase harder to read than upper and lower case (known as “mixed case”).  Mixed case words are easier to read because they make unique shapes, as demonstrated by the picture below.

The shapes of words

OK, NOW THE TRUE STUFF STARTS — When I started this article the topic was supposed to be why all capital letters are harder to read. Like most people with a usability background or a cognitive psychology background, I can describe the research — just what I wrote in the first paragraph above. I decided to look up and cite the actual research rather than just passing on the general knowledge and belief.

The research doesn’t exist, or “It’s complicated” — Something happened when I went to find the research on the shape of words and how that is related to all capital letters being harder to read. There isn’t research showing that exactly. It’s more complicated, and ultimately, more controversial. In July of 2004 Kevin Larson wrote an article that is posted at the Microsoft website that explains in depth all the research on this topic. I’ve picked out several ideas from that article and am presenting them here. A link to Kevin’s article, plus some of his research citations are at the end of this blog for those of you who want more detail. read more »
