Conservatives and liberals do think differently
Research shows different ways of solving everyday problems linked to political ideology.
Big differences in the ways conservatives and liberals think about solving the nation's most pressing problems couldn't be more apparent during this presidential election cycle. But political ideas aside, people who hold conservative versus liberal perspectives appear to differ in everyday thinking processes and problem solving, according to new research.

When solving short (non-political) verbal problems in an experiment, liberals were more likely than conservatives to achieve solutions with a sudden insight or "Aha!" In contrast, both groups achieved roughly an equal number of solutions through gradual, analytical processing.

Different from instinctive or gut reactions, insight problem solving occurs when after working on a problem for awhile and maybe feeling stuck, a solution unexpectedly emerges into consciousness in an 'Aha!' moment. The problem is suddenly seen in a new light, often surprising the solvers who are typically unaware of how the reorganization of their thought processes occurred.

Insight solutions contrast with methodical and analytical problem solving, which involve a gradual approach toward the solution and awareness of the steps involved.

"This view is consistent with similar results from other labs across behavioral, neuroscientific and genetic studies, which converge in showing that conservatives have more structured and persistent cognitive styles," said Carola Salvi, lead author of the study and a postdoctoral fellow in cognitive psychology at Northwestern and RIC.

"Liberals have a less structured and more flexible cognitive style, according to those studies. Our research indicates that cognitive differences in people with different political orientations also are apparent in a task that some consider to be convergent thinking: finding a single solution to a problem," Salvi said.

Given previous findings relating political orientation with cognitive styles, the researchers hypothesized that liberals and conservatives would preferentially employ different processes when tackling problems that could be solved using either an analytical or insight approach.

"It's not that there's a different capacity to solve problems," stressed Mark Beeman, senior author of the study and professor and chair of psychology at Northwestern. "It's more about which processes people end up engaging in to solve the problem."

And it's not about preferences, said Jordan Grafman, co-author of the study and professor in physical medicine and rehabilitation at Northwestern's Feinberg School of Medicine and director of brain injury research at RIC.

"People may default automatically to a particular approach out of habit or predisposition, but they are not consciously choosing to solve a problem one way or the other," Grafman said.

Approximately 130 Northwestern students were randomly assigned to the study. Those whose survey responses demonstrated a particular political ideology were ultimately divided into either a liberal or conservative group and balanced for age and ethnicity. A third group of students who scored "neutral" were excluded from the analysis.

To test their hypothesis, the researchers used a well-known task in the problem-solving literature -- the Compound Remote Associate (CRA) problems. These problems can be solved through either insight or analytic processes with participants reporting how they solved each problem. Each problem consisted of the simultaneous presentation of three words, each of which could form a compound word or phrase with the solution word. For example: pine/crab/sauce -- the solution word is APPLE.

Past research has demonstrated that different mental processes and distinct brain regions are involved when people report solving these problems with insight, versus when solving analytically.

"Liberals tended more than conservatives to use insight to solve verbal problems in which you have to 'think outside the box,'" Salvi said.

In life you often use both approaches, Salvi noted.

"Everyday life presents us with a variety of scenarios where we are asked to solve problems analytically, others only with a spark of insight, most of them can be solved either way," Salvi said. "In this last case, liberals are more likely to achieve the solution with an 'Aha!' moment, whereas conservatives' problem solving approach does not prefer one style or the other."

"The Politics of Insight" is published online in The Quarterly Journal of Experimental Psychology. In addition to Salvi, Grafman and Beeman, Irene Cristofori of RIC and the department of Physical Medicine and Rehabilitation, Feinberg School of Medicine, also is a co-author of the study.

Workout supplements: An emerging eating disorder in men?

Image
therewontbeanydoves.wordpress.com When developing a fictional character, you may not think about the character using large amounts of over-the-counter dietary supplements.  Especially a man who uses large amounts of workout supplements. While there has been widespread publicity on the dangers of the non-prescribed use of anabolic steroids, not much is said about legal, over-the-counter supplements.  Are there risks?  And if so, what are they?  There are several things the writer should consider. Supplement use is becoming an eating disorder with many men who use them to prepare for and recover from a workout. There is growing evidence of a link between muscle-building supplements and testicular cancer. There is evidence that over-the counter medications and supplements are the most common causes of drug-induced liver failure (a rare event, but still a risk.)  There is even evidence that, “certain popular herbal and dietary supplements can also ...

Remember faces but not names? You got it wrong.

Source:   Daily Excelsior So, you think you're good at remembering faces, but terrible with names? New research has revealed we are actually better at remembering names than faces The cringe-worthy experience of not being able to remember an acquaintance's name leads many of us to believe we are terrible with names. However, new research has revealed this intuition is misleading; we are actually better at remembering names than faces. With the Christmas party season fast approaching, there will be plenty of opportunity to re-live the familiar, and excruciatingly-awkward, social situation of not being able to remember an acquaintance's name. This cringe-worthy experience leads many of us to believe we are terrible at remembering names. However, new research has revealed this intuition is misleading; we are actually better at remembering names than faces. The authors of the study, from the University of York, suggest that when we castigate ourselves f...

Children's drawings during abuse investigations

Image
Source:  rutherfordcountytn.gov I llustrations by children can be a critical tool in forensic investigations of child abuse. A recent study compared the results when child abuse victims were offered the opportunity to draw during questioning with results when victims were not offered this opportunity. "The act of drawing was not only an empowering experience for these children," said Dr. Katz. "We also found it to be forensically more effective in eliciting richer testimonies in child abuse cases. We had no idea the gap would be so great between those who drew and those who weren't given this option." A chance to express themselves Some 125 alleged child victims of sexual abuse were randomly selected for the field study. The children, aged 5-14, were questioned by nine well-trained forensic interviewers about a single occurrence of alleged sexual abuse. The children were divided into two sets -- a control group, questioned and allowed to rest during t...

M.I.T. Research Explains How Will Rogers Observation Works

Image
Finally it appears that MIT has gotten involved in proving Will's syllogism, "There are three kinds of men. The one that learns by reading. The few who learn by observation. The rest of them have to pee on the electric fence for themselves." Read his statement carefully.   ONE learns by reading.   A FEW who learn by observation. Then there's the rest of us. The reason for this, it turns out, is a special circuit in the brain that you or I need to have a functioning version of to actually learn by observing others.  Based on how we all behave, it is a circuit most of us must be missing.   Or perhaps it shorted out the first time we peed on an electric fence and it has yet to grow back.   *  *  *  *  * Brain circuit helps us learn by watching others Scientists pinpoint neural interactions that are necessary for observational learning Researchers have identified a brain circuit requir...
