Antagonistic people may increase heart attack, stroke risk

American Heart Association rapid access journal report

Antagonistic people, particularly those who are competitive and aggressive, may be increasing their risk of heart attack or stroke, researchers report in Hypertension: Journal of the American Heart Association.

Researchers for the U.S. National Institute on Aging (NIA), a component of the National Institutes of Health (NIH), studied 5,614 Italians in four villages and found that those who scored high for antagonistic traits on a standard personality test had greater thickening of the neck (carotid) arteries compared to people who were more agreeable. Thickness of neck artery walls is a risk factor for heart attack and stroke.

Three years later, those who scored higher on antagonism or low agreeableness - especially those who were manipulative and quick to express anger - continued to have thickening of their artery walls. These traits also predicted greater progression of arterial thickening.

Women have a greater empathetic capacity than males.
A study by the University of the Basque Country (UPV/EHU) has carried out the first Spanish study into the emotional differences between the sexes and generations in terms of forgiveness. According to the study, parents forgive more than children, while women are better at forgiving than men.

"This study has great application for teaching values, because it shows us what reasons people have for forgiving men and women, and the popular conception of forgiveness", Maite Garaigordobil, co-author of the study and a senior professor at the Psychology Faculty of the UPV, tells SINC.

This study, which has been published in the Revista Latinoamericana de Psicología, is the first to have been carried out in Spain. It shows that parents find it easier to forgive than their children, and that women are better at forgiving than men.

Juggling languages can build better brains

Once likened to a confusing tower of Babel, speaking more than one language can actually bolster brain function by serving as a mental gymnasium, according to researchers.

Recent research indicates that bilingual speakers can outperform monolinguals--people who speak only one language--in certain mental abilities, such as editing out irrelevant information and focusing on important information, said Judith Kroll, Distinguished Professor of Psychology, Penn State. These skills make bilinguals better at prioritizing tasks and working on multiple projects at one time.

"We would probably refer to most of these cognitive advantages as multi-tasking," said Kroll, director of the Center for Language Science. "Bilinguals seem to be better at this type of perspective taking."

Kroll said that these findings counter previous conclusions that bilingualism hindered cognitive development.

Iowa State study examines why innocent suspects may confess to a crime

Iowa State psychologists Stephanie Madon (far right) and Max Guyll (middle right) have been overseeing experiments -- like this one by ISU students Shelby Wuebker and Lee Casavant -- on the consequences that drive a person's confession decisions.
Why would anyone falsely confess to a crime they didn't commit? It seems illogical, but according to The Innocence Project, there have been 266 post-conviction DNA exonerations since 1989 -- 25 percent of which involved a false confession.

A new Iowa State University study may shed light on one reason for those false confessions. In two experiments simulating choices suspects face in police interrogations, undergraduate subjects altered their behavior to confess to illegal activities in order to relieve short-term distress (the proximal consequence) while discounting potential long-term (distal) consequences.

"The thing about these exoneration cases is that they all pertained to heinous crimes; that's why there was DNA evidence available. And so we wanted to determine why someone may be willing to falsely confess to one of those crimes," said Stephanie Madon, an ISU associate professor of psychology and the study's lead author. "We thought it might have to do with the pay-off structure of police interrogations. Some interrogation methods -- like physical isolation and the presentation of false evidence -- have immediate consequences for suspects that encourage them to confess. Though they also face consequences that encourage them to deny guilt -- such as the possibility of conviction and incarceration -- these consequences are more distal.

How Couples Recover After an Argument Stems From Their Infant Relationships

When studying relationships, psychological scientists have often focused on how couples fight. But how they recover from a fight is important, too. According to a new study published in Psychological Science, a journal of the Association for Psychological Science, couples' abilities to bounce back from conflict may depend on what both partners were like as infants.

Researchers at the University of Minnesota have been following a cohort of people since before they were born, in the mid-1970s. When the subjects were about 20 years old, they visited the lab with their romantic partners for testing. This included a conflict discussion, when they were asked to talk about an issue they disagreed on, followed by a "cool-down" period, when the couples spent a few minutes talking about something they saw eye to eye about.

Although the cool-down period was included just to make sure the researchers weren't sending the couples away angry, Jessica E. Salvatore, a Ph.D. student at the University of Minnesota, noticed some interesting things about the couples' communication styles during this recovery time. "As part of another project where we looked at how couples fight, I would often catch a few minutes of this cool-down period," she says. Salvatore noticed that some couples had intense conflicts, but made a perfectly clean transition to chatting about something they agreed on. In other couples, one or both partners seemed "stuck" on the conflict discussion and couldn't move on.

The man who can 'taste' words: 'Gordon Brown tastes revolting, while Tony Blair tastes of desiccated coconut'

Taste of life: James Wannerton suffers from gustatory auditory synaesthesia.
James Wannerton, 50, is one of an estimated two-and-a-half million people who suffer from gustatory auditory synaesthesia, a cross-sensory neurological condition, which means he can literally taste words. A systems analyst, he lives in Blackpool, Lancashire, with his partner, Jeanette. Here, he talks about how it has affected his life.

One of my earliest memories was when I was about four or five and chanting The Lord's Prayer in school assembly.

But it's not the words, the school hall or the teachers I remember most. It's the flavours, because The Lord's Prayer tasted unmistakably of bacon.

It was the first time I'd experienced tasting words, and most of my early memories are dominated by taste more than any other sense.

At school, I was always one of the dreamy kids - staring out of the window and tasting stuff. Blue was lovely, like a very soft Opal Fruit sweet. My family holidays in Devon tasted strongly of brick dust. Other trips tasted of chocolates and wine gums.

Lie Detection: Misconceptions, Pitfalls, and Opportunities for Improvement

Unlike Pinocchio, liars do not usually give telltale signs that they are being dishonest. In lieu of a growing nose, is there a way to distinguish people who are telling the truth from those who aren't? A new report in Psychological Science in the Public Interest, a journal of the Association for Psychological Science, discusses some of the common misconceptions about those proficient in the art of deception, reviews the shortcomings of commonly used lie-detection techniques, and presents new empirically supported methods for telling liars from truth-tellers with greater accuracy.

Trapping a liar is not always easy. Lies are often embedded in truths and behavioral differences between liars and truth-tellers are usually very small. In addition, some people are just very good at lying. Lie detectors routinely make the common mistakes of overemphasizing nonverbal cues, neglecting intrapersonal variations (i.e., how a person acts when they are telling the truth versus when they are lying), and being overly confident in their lie-detection skills.

Dependency, the Dark Side of Support: A Helpful Partner Isn't Always Helpful

You might think that a loving partner helps keep you on track - say, when you want to stick to your jogging or concentrate on your studies. But a new study in Psychological Science, a publication of the Association of Psychological Science, reports the opposite: Thinking about the support a significant other offers in pursuing goals can undermine the motivation to work toward those goals - and can increase procrastination before getting down to work.

The study's authors, psychological scientists Gráinne M. Fitzsimons of Duke University and Eli J. Finkel of Northwestern University, call this phenomenon "self-regulatory outsourcing" - the unconscious reliance on someone else to move your goals forward, coupled by a relaxation of your own effort. It happens with friends and family, too.

Does this mean love doesn't bring out the best in us? Yes and no, says Fitzsimons. "If you look just at one goal" in isolation - as the study does - "there can be a negative effect. But relying on another person also lets you spread your energy across many goals, which can be effective if your partner is helpful."

Stress, Anxiety Both Boon and Bane to Brain

brain

A cold dose of fear lends an edge to the here-and-now - say, when things go bump in the night.
"That edge sounds good. It sounds adaptive. It sounds like perception is enhanced and that it can keep you safe in the face of danger," says Alexander Shackman, a researcher at the University of Wisconsin-Madison.

But it sounds like there's also a catch, one that Shackman and his coauthors - including Richard Davidson, UW-Madison psychology and psychiatry professor - described in the Jan. 19 Journal of Neuroscience.

"It makes us more sensitive to our external surroundings as a way of learning where or what a threat may be, but interferes with our ability to do more complex thinking," Davidson says.

Faced with the possibility of receiving an unpleasant electric shock, the study's subjects showed enhanced activity in brain circuits responsible for taking in visual information, but a muted signal in circuitry responsible for evaluating that information. Remove the threat of shock (and thus the stress and anxiety) and the effect is reversed: less power for vigilance, more power for strategic decision-making.

Comment: The solution to the paradox? Pay attention to realty left and right, learning about the dangers of the world, but with periods of respite so that we are able to evaluate what we see and our decisions with a clear and fully functional mind. Reading SOTT.net is a great way to do the former, and as for the latter, Éiriú Eolas is an excellent practice for dealing with the negative effects of stress and anxiety.

Brain Regions Sleep More Deeply When Used More

Sleepy Birds

During deep sleep the brain is highly electrically active - but only in those regions, which were heavily used previously while awake.
When we are asleep, those regions of our brain that were particularly active during wakefulness sleep more deeply. Researchers at the Max Planck Institute for Ornithology in Seewiesen, Germany and colleagues have demonstrated for the first time that this is also the case in birds.

The researchers prevented pigeons from taking their afternoon nap by showing them David Attenborough's nature documentary series The Life of Birds. An eye cap temporarily covered one eye during the movie session. During the following night, the researchers observed deeper sleep in the part of the brain neurologically connected to the stimulated eye compared with the same region in the other brain hemisphere. A non-visual region did not show such an asymmetry in sleep.

Birds are the only animals outside of mammals whose sleep is also divided into a deep sleep phase, the so-called "Slow Wave Sleep" (SWS) and a dream phase, REM sleep ("Rapid Eye Movement Sleep"). During SWS sleep the brain generates strong electrical signals which are manifested as high-amplitude low-frequency waves in the electroencephalogram (EEG).

Comment: The quality of your sleep depends on the quality of your life, and vice versa. For more information on sleep, please visit our forum discussion "Are You Getting Enough Sleep? Sleeping properly?" which includes excerpts from T.S. Wiley's book Lights Out.
