Researchers have mapped the moods of Twitter users from the UK and found that they follow a daily pattern of anger, fear, joy and sadness.
The research paper, posted online last week, was based on approximately 120 million tweets collected during the summer and winter of 2011.
The researchers counted the number of times a tweet expressed anger, fear, joy or sadness and normalised this by the total number of tweets in that hour. This corrected for the inevitably higher use of Twitter during........ Read more »

Millions of people yearn for happiness. We should know now that science can help. That “good news” headline can apply to article recently published in a leading psychological science journal and featured in this post. Happiness feels good, does good, is good for us, and can lead to success. Research shows that the deliberate [...]The post The How, What, When, and Why of [Lawyer] Happiness Increasing Strategies: Initial Understanding From the “Positive-Activity Model........ Read more »

How often have you read that “the eyes are the window to the soul”? What that means, say proponents, is that all you have to do to know how someone feels is to look into their eyes and you know all. New research would say that only holds true (at least if you are a [...]

Sometimes leaders epitomise the group they seek to lead, such as a former trucker heading a transport trade union. In other cases leaders are less prototypical; while they may have the attributes for the role, they 'come from outside'. How might leaders from these two moulds respond when the workplace demands more accountability for their actions? A team led by Steffen Giessner of Erasmus University set out to know more, investigating the team-oriented behaviours that leaders engage in whe........ Read more »

Researchers have found that minocycline, an antibiotic, can protect men from the apparent attraction of women in making better decisions especially financial decisions.

In 2004, in Silicon Valley, Google posted a huge billboard ad featuring a mathematical problem. The answer led to a web address with yet another puzzle to crack. People who successfully followed this intellectual treasure hunt ended up being invited in for a job interview.

It’s a familiar story: women who say they are looking to date a kind, sensitive and emotionally expressive guy often end up dating a macho man or a jerk.

Why do some people recover anorexia nervosa relatively quickly while others seem to struggle for years or decades? Does it depend on the person’s desire to get better? Their willpower? How much they are willing to fight? Is it just that some try harder than others? Some might say yes, but most will correctly realize that the picture is much, much more complex.

I recently read a 2006 paper titled "Visceral Influences on Risk-Taking Behavior." In spite of it's problems this paper uses some great language. Take for example this opening paragraph from the introduction:"People often do things that they almost immediately regret. Would-be dieters succumb to the lure of forsworn foods, only to curse their weak wills once their hunger (or the food) is gone. Unfaithful spouses live wracked with guilt after an impulsive sexual dalliance, only to repeat the cycl........ Read more »

"Vaccine". "Autism".I'm struggling to think of two words in combination which, in modern times, are any more likely to stir up emotion, debate and even argument. Indeed in these times of measles outbreaks and seemingly daily news reporting on the very, very strong requirement for vaccination to protect against the disease, it is coincidental that two research papers should now land in my inbox which mention both of those words in the title.Paradise in Zakynthos @ Wikipedia The fi........

Researchers have found that, in 2010, about 32 million people in the U.S. have used hallucinogenic drugs such as LSD (lysergic acid diethylamide), “magic mushrooms” (psilocybin), or mescaline (peyote and other cacti) at some point in their lives and many of them have used it in the recent past.

In Part 1 of this topic, we explored the reasons why we like certain songs. But what transforms that likable melody into an earworm? Or is likability even a contributing factor?

It’s a very attractive idea that we can discover the truth about the stories people tell just by looking at what their eyes are doing. People for example often look to the left if they use their memory, so if they don’t, they can’t be telling anything sincere about the past. What does science make of this?... Read more »
