Sweet Tooth Equals a Sweet Deal

Posted on 2011/10/182011/10/19 by Jason Hensel

Your sweet tooth is more than a preference for desserts. It’s also an indicator of your personality and behavior, according to a study in the Journal of Personality and Social Psychology.

Let’s read the study’s abstract together:

It is striking that prosocial people are considered “sweet” (e.g., “she’s a sweetie”) because they are unlikely to differentially taste this way. These metaphors aid communication, but theories of conceptual metaphor and embodiment led us to hypothesize that they can be used to derive novel insights about personality processes. Five studies converged on this idea. Study 1 revealed that people believed strangers who liked sweet foods (e.g., candy) were also higher in agreeableness. Studies 2 and 3 showed that individual differences in the preference for sweet foods predicted prosocial personalities, prosocial intentions, and prosocial behaviors. Studies 4 and 5 used experimental designs and showed that momentarily savoring a sweet food (vs. a nonsweet food or no food) increased participants’ self-reports of agreeableness and helping behavior. The results reveal that an embodied metaphor approach provides a complementary but unique perspective to traditional trait views of personality.

The part about increased agreeableness through sweets fascinates me. Do this mean you should bring sweets with you before every meeting? What does it say about someone who doesn’t like sweets? Does a preference for chocolate over hard candy indicate a different type of sweet and agreeable personality? So many questions.

Practice May Not Be Perfect

Posted on 2011/10/17 by Jason Hensel

One of my goals this year is to write more so that I can become a better writer. If I’m not writing on 750words.com, then I’m doing my best to write at least 20 minutes a day.

Why do I do this? Well, I love writing; however, I also know that practice makes perfect. Or so I thought.

Now comes along Zach Hambrick from the University of Michigan. He says that working memory capacity may be what ultimately makes a person great.

“While the specialized knowledge that accumulates through practice is the most important ingredient to reach a very high level of skill, it’s not always sufficient,” said Hambrick, associate professor of psychology. “Working memory capacity can still predict performance in complex domains such as music, chess, science and maybe even in sports that have a substantial mental component such as golf.”

Hambrick says that when someone such as Malcolm Gladwell writes that practice is what separates those who are good and great, he’s wrong.

“The evidence is quite clear: A high level of intellectual ability puts a person at a measurable advantage–and the higher the better.”

However, it’s still not known if a person can improve his general intelligence, because a lot of it based in genetics and environments.

“We hold out hope that cognitive training of some sort may produce these benefits,” Hambrick said. “But we have yet to find the magic bullet.”

Until then, I’ll keep practicing.

Which do you find makes you greater in your chosen pursuit: intelligence or practice?

Sleep Could Improve Your Memory

Posted on 2011/10/032011/10/02 by Jason Hensel

I’m a night owl. I’m one of those people who works better at night and feels like there is a lot to do while awake. Sleep can come later. And studies have shown that night owls have higher intelligence than those who wake up early. Yep, stay up late and become smarter. I knew I was doing something right.

Not so fast, opposing scientists say. In fact, sleep helps you learn and remember.

“We speculate that we may be investigating a separate form of memory, distinct from traditional memory systems,” said Kimberly Fenn, assistant professor of psychology at the University of Michigan. “There is substantial evidence that during sleep, your brain is processing information without your awareness and this ability may contribute to memory in a waking state.”

In a study appearing in the Journal of Experimental Psychology: General, findings suggest people derive vastly different effects from “sleep memory,” with some memories improving dramatically and others not at all. This ability is a new, previously undefined form of memory.

“You and I could go to bed at the same time and get the same amount of sleep,” Fenn said. “But while your memory may increase substantially, there may be no change in mine.”

She added that most people in the study showed improvement.

Fenn says she believes this potential separate memory ability is not being captured by traditional intelligence tests and aptitude tests such as the SAT and ACT.

“This is the first step to investigate whether or not this potential new memory construct is related to outcomes such as classroom learning,” she said.

It also reinforces the need for a good night’s sleep.

“Simply improving your sleep could potentially improve your performance in the classroom,” Fenn said.

My memory is not what it used to be, and I’ve chalked that up to getting older. Maybe, though, it’s my lack of sleep. Maybe I’m trading memory for intelligence, and I’m not sure that’s an exchange I want to make. Would you?

Embarrassed People are More Trustworthy

Posted on 2011/09/30 by Jason Hensel

You may be embarrassed by being embarrassed, but that’s not a bad thing. In fact, it makes you more trustworthy.

“Embarrassment is one emotional signature of a person to whom you can entrust valuable resources,” said University of California Berkeley social psychologist Robb Willer, a coauthor of a study published in this month’s online issue of the Journal of Personality and Social Psychology. “It’s part of the social glue that fosters trust and cooperation in everyday life.”

The researchers conducted a few experiments to get to their findings.

In the first experiment, they videotaped 60 college students recounting embarrassing moments such as public flatulence or making incorrect assumptions based on appearances. Typical sources of embarrassment included mistaking an overweight woman for being pregnant or a disheveled person for being a panhandler. Research assistants coded each video testimonial based on the level of embarrassment the subjects showed.

The college students also participated in the “Dictator Game,” which economics researchers use to measure altruism. For example, each was given 10 raffle tickets and asked to keep a share of the tickets and give the remainder to a partner. Results showed that those who showed greater levels of embarrassment tended to give away more of their raffle tickets, indicating greater generosity.

Researchers also surveyed 38 Americans whom they recruited through Craigslist. They asked survey participants how often they feel embarrassed. They were also gauged for their general cooperativeness and generosity through such exercises as the aforementioned dictator game.

In another experiment, participants watched a trained actor being told he received a perfect score on a test. The actor responded with either embarrassment or pride. They then played games with the actor that measured their trust in him based on whether he had shown pride or embarrassment.

The results consistently showed that embarrassment signals people’s tendency to be pro-social.

“You want to affiliate with them more,” said Matthew Feinberg, a doctoral student in psychology at UC Berkeley and lead author of the paper. “You feel comfortable trusting them. Moderate levels of embarrassment are signs of virtue. Our data suggests embarrassment is a good thing, not something you should fight.”

How easily do you get embarrassed?
