I recently read an article in the magazine Psychology Today  that discusses a phenomenon in social perception called the Doppelgänger Bias .  For starters, a doppelgänger is a non-biologically related look-alike or double of a living person. In books and movies, it is sometimes portrayed as a ghostly or paranormal apparition and usually deemed a harbinger of bad luck. Our prior knowledge of a person -- whether he/she has treated you well or poorly -- determines how you act toward that individual in the future. But research suggests that a person's track record may also affect how you treat people who look like the person in question. In studies headed by Brown University neuroscientist Oriel FeldmanHall, participants played a money-sharing game with several "male partners" whose headshots appeared onscreen. (Players were lead to believe they were dealing with actual people, but the partners were virtual.) As the study participants played, they discovered these ...

Studies show that far more women are skipping marriage today than was the case two, even three decades ago. Plus, what many women are saying on social media regarding the perils of tying the knot corroborates these findings. This morning, I was sifting through posts on the Facebook page for Psychology Today. One of them posed an intriguing question: Do women these days still find great value in getting married? Judging from the comments to the post, many of them do not. One woman stated plainly that after dating several non-committal men, she's grown tired of pushing marriage on these guys with nothing to show for it. Another said that she refuses to take the plunge again after being cheated on by two of her husbands. Still another admitted that she's never wanted to be tied down, instead valuing the flexibility of singlehood. For many women, the perks of being married -- like additional tax and insurance benefits -- just aren't sufficient to offset the problems tha...

During which months of the year do you think suicides are most prevalent? Contrary to popular belief, suicide attempts actually drop during the holidays. The lower suicide rates are thought to be linked to increased family time and support during this time of year. According to Psychology Today , there were over 38,000 suicides in the U.S. in 2010, making it the 12th leading cause of death. To put this in perspective, more people died from suicide than automobile accidents. While ephemeral thoughts of suicide are common in many people, suicide threats often go ignored. Suicide is often associated with depression, which is, of course, treatable. I've read one too many stories of people whose suicide threats fell on deaf ears. In other cases, people stop short of making actual threats, but they show various signs of depression -- from loss of appetite to incessant crying -- that propel them to do the unthinkable. It's imperative that anyone with thoughts of suicide be tak...
