When JetBlue flight attendant Steven Slater creatively deplaned earlier this week, many questions arose as to why someone would be willing to give up a steady paycheck during these tough economic times. While this "working man's hero" will most likely be questioning his motives as he hands over his lawyer's fees, a new report in Perspectives on Psychological Science, a journal of the Association for Psychological Science, suggests that his action may be a sign of trouble for JetBlue and other large companies.

Finding Meaning in the Second Half of Life: How to Finally, Really Grow Up

What does it really mean to be a grown up in today’s world? We assume that once we "get it together" with the right job, marry the right person, have children, and buy a home, all is settled and well. But adulthood presents varying levels of growth, and is rarely the respite of stability we expected.

It's a symbol of courage and sacrifice, of sin and sexuality, of power and passion – and now new research demonstrates that the color red makes men more alluring to women.

In the United States, England, Germany and China, women found men more appealing when they were either pictured wearing red or framed in red, compared with other colors. The finding is reported in the August issue of the Journal of Experimental Psychology: General, published by the American Psychological Association.

"Red is typically thought of as a sexy color for women only," said Andrew Elliot, PhD, of the University of Rochester and University of Munich. "Our findings suggest that the link between red and sex also applies to men."

Teenage years have long been linked with a heightened concern with appearance. Some reality TV shows take full advantage and tout happiness as just a nip/tuck away. A Rutgers–Camden psychologist has found that teens fond of these kinds of programs are more likely to join the millions who go under the knife each year. For bodies - and minds - still in development, these drastic decisions could have implications way after prom.

Just how important is your environment's influence on the way you feel or think? In news that won't surprise people who hate or love where they live - it turns out that for mice at least, environment makes a big difference.

Researchers at the University of Colorado's Anschutz Medical Campus have found the brains of mice used in laboratories worldwide can be profoundly affected by the type of cage they are kept in, a breakthrough that may require scientists to reevaluate the way they conduct future experiments.

A worldwide survey of more than 136,000 people in 132 countries included questions about happiness and income, and the results reveal that while life satisfaction usually rises with income, positive feelings don't necessarily follow, researchers report.

The findings, from an analysis of data gathered in the first Gallup World Poll, appear in the Journal of Personality and Social Psychology.

"The public always wonders: Does money make you happy?" said University of Illinois professor emeritus of psychology Ed Diener, a senior scientist with the Gallup Organization. "This study shows that it all depends on how you define happiness, because if you look at life satisfaction, how you evaluate your life as a whole, you see a pretty strong correlation around the world between income and happiness," he said. "On the other hand it's pretty shocking how small the correlation is with positive feelings and enjoying yourself."

A new University of British Columbia study says that an overreliance on research subjects from the U.S. and other Western nations can produce false claims about human psychology and behavior because their psychological tendencies are highly unusual compared to the global population.

According to the study, the majority of psychological research is conducted on subjects from Western nations, primarily university students. Between 2003 and 2007, 96 per cent of psychological samples came from countries with only 12 per cent of the world's populations. The U.S. alone provided nearly 70 per cent of these subjects.

However, the study finds significant psychological and behavioral differences between what the researchers call Western, Educated, Industrialized, Rich and Democratic (WEIRD) societies and their non-WEIRD counterparts across a spectrum of key areas, including visual perception, fairness, spatial and moral reasoning, memory and conformity.

Look at a person's photo and it's tempting to think you can see their personality written all over it: stony-faced individuals appear somber; others flashing a big, toothy grin seem more genial, the British Psychological Society reports. An intriguing new study claims that these smiles are a reliable marker of underlying positive emotion and as such are predictive of a person's longevity.

Ernest Abel and Michael Kruger had five people rate the smile intensity of 230 baseball players according to photos featured in the 1952 Baseball Register. The researchers used a three-point smile scale: no smile, half smile (mouth only), and genuine 'Duchenne' smile (muscles contracted around the mouth and corners of the eyes).

Focusing on the 150 players who'd died by the time of the study and controlling for extraneous factors such as BMI and marital status, the researchers found that those who were flashing a genuine 'Duchenne Smile' were half as likely to die in any given year compared with non-smilers. Indeed, the average life-span of the 63 deceased non-smilers was 72.9 years compared with 75 years for the 64 partial smilers and 79.9 years for the 23 Duchenne smilers.

If you're having trouble getting a date, French researchers suggest that picking the right soundtrack could improve the odds. Women were more prepared to give their number to an 'average' young man after listening to romantic background music, according to research that appears today in the journal Psychology of Music, published by SAGE.

There's plenty of research indicating that the media affects our behaviour. Violent video games or music with aggressive lyrics increase the likelihood of aggressive behaviour, thoughts and feelings – but do romantic songs have any effect? This question prompted researchers Nicolas Guéguen and Céline Jacob from the Université de Bretagne-Sud along with Lubomir Lamy from Université de Paris-Sud to test the power of romantic lyrics on 18-20 year old single females. And it turns out that at least one romantic love song did make a difference.

Excessive sleepiness is more common in the U.S. than in Europe, which raises concerns for public health and safety, according to  research presented at SLEEP 2010, the 24th annual meeting of the Associated Professional Sleep Societies LLC.

Results indicate that 19.5 percent of U.S. adults reported having moderate to excessive sleepiness, which was comparable between men and women. Furthermore, 11 percent of participants reported severe sleepiness, which was more prevalent in women (13 percent) than in men (8.6 percent).

"The prevalence of excessive daytime sleepiness is very high in the American population, much higher than what we observed in the European population," said principal investigator Dr. Maurice Ohayon, professor of psychiatry at Stanford University and director of the Stanford Sleep Epidemiology Research Center in Palo Alto, Calif. In a study published in the June 2002 issue of the journal Neurology, Ohayon reported that the prevalence of excessive daytime sleepiness in five European countries was 15 percent.

"Insufficient sleep is plaguing the American population and is one of the leading factors for excessive daytime sleepiness," Ohayon added.
