"I'd better check......one more time.....just let me make sure.....I'd better go back...." In isolation these comments might come from anyone wondering whether the headlights are turned off on the car. But as the mantra of people suffering from obsessive-compulsive disorder (OCD) these thoughts plague their daily lives. Whether its washing one's hands 25 times a day (above, scene taken from The Aviator (2004)) or checking to make sure the stove burner is off every hour on the hour, OCD can severely hobble one's peace of mind.

More rightly, it may be a piece of brain that produces these intrusive thoughts. UCLA's Jeffrey Schwartz and his colleagues used PET scans to study the brains of obsessive-compulsive patients. They found that the orbita ...

Learning about how to become an elephant is almost synonymous with learning how to rediscover what it means to be human. Understanding elephants and saving elephants is a lesson in humanity. So many traits that are innate in elephants are those that we humans strive to be and possess. The "Elephant Lessons" take what we learn about elephant minds, culture and lives and applies it to our own everyday living to cultivate elephant qualities that are within each of us. Today's Lesson focuses on the Importance of Family.

A new psychology study suggests that women are better than men at reading people's thoughts and emotions, just by looking at the eyes.

Researchers from around the globe tested the way genes influence a person's cognitive empathy; their ability to accurately recognise another person's emotional state. 90,000 people were shown different photographs of people's eyes and asked to determine their mood. Results showed that women more consistently picked the correct feeling when the participants had to select what emotion they perceived when shown a visual of a person's eyes.

This is the first big study on cognitive empathy and its relationship to gender. The international research team has also identified a potential genetic region that influences ...

If you've ever been told to give a firm handshake at the start of an interview, this advice now holds scientific truth with a new study published by Frontiers in Psychology.

According to the study, hand grip strength correlates with numerous measures involved in social and sexual competition in men, and typically fails to correlate (or to a lesser extent) with these measures among women. Given that this trait scores highest in people between the ages of 24 and 39 years, and subsequently weakens as we age, the author insists that hand grip strength is a powerful indicator of health and vitality for both men and women, as it relates to overall physical functioning and morbidity.

Researchers of the study mention that the predominantly male-speci ...

Despite his mother beckoning him to come towards her, this infant hesitates to cross the "visual cliff" – an apparently steep drop that is actually covered by transparent glass. Psychologists in the 1960s found that most infants 6 to 14 months of age were reluctant to crawl over the cliff, suggesting they had the ability to perceive depth. Most psychologists believe that the ability to perceive depth is partly innate and partly a product of early visual experience.

Here's a test you can try to demonstrate how your perception of depth is still live and active. Below are two perfect circles, yet the smaller circle appears distorted. Our brain interprets the converging lines to be adding depth to the screen, as if the solid middle is further aw ...

Bayer Corporation and the Public Health Committee of the American Society for Microbiology sponsored a study of hand washing in public restrooms. Researchers from the survey group hid in stalls or pretended to comb their hair while they observed over 6,000 men and women in five large cities. Their observations revealed that many people prefer a "get up and go" strategy, failing to wash their hands after using the restroom facilities. In New York's Penn Station, for example, only 60% of restroom users washed after relieving themselves. Similar rates were found in other cities: 64% of restroom users washed at a Braves game in Atlanta, 69% washed in San Francisco's Golden Gate Park, 71% used soap and water in a New Orleans casino, and a laudab ...

If emotions can make you sick, if a belief that you will die can kill you (as in voodoo deaths), and if a sugar pill that you believe is a powerful drug can take away your pain, can a belief that you can bring about your own recovery help you to recover?

Even with acceptance of the role of emotional factors in both illness and recovery, the assumption has persisted that emotional factors work on an unconscious level, and because of this they are not subject to voluntary control. Most of us still see illness as something that happens to us.

Dr. Carl Simonton, chief of radiation at Travis Air Force Base, questioned this assumption. He was impressed by demonstrations that people could learn to control autonomic processes through biofeedback and ...

Pareidolia is a phenomenon that allows us to "see" faces and other objects in completely unrelated objects and settings. Carl Sagan theorized that this provided an evolutionary advantage, as it allows humans to better recognize each other, even under poor visual circumstances. The important thing to remember is that even though these images may seem significant and life-changing, they aren't. It's all just a really fun figment of your imagination.
