Is Your Left Hand More Motivated Than Your Right?
Motivation doesn't have to be conscious; your brain can decide how much it wants something without input from your conscious mind. Now a new study shows that both halves of your brain don't even have to agree. Motivation can happen in one side of the brain at a time. Psychologists used to think that motivation was a conscious process. You know you want something, so you try to get it. But a few years ago, Mathias Pessiglione, of the Brain & Spine Institute in Paris, and his colleagues showed that motivation could be subconscious; when people saw subliminal pictures of a reward, even if they didn't know what they'd seen, they would try harder for a bigger reward.

Goalkeeping with an ancient mind
Behavioral economist Ofer Azar did an intriguing study of premier soccer goalies a few years ago, worth dusting off for the World Cup. Azar, a lecturer at Ben-Gurion University in Israel, studied penalty kicks. A penalty kick is awarded after a foul, and is often used as a tie-breaker in championship games. A designated player stands 36 feet from the goal, which measures 24 feet side to side. Only the opposing goalie stands between the kicker and the goal, so it’s a high probability shot. In fact, with the typical penalty kick flying at more than 60 miles per hour, the goalie has only a fraction of a second to respond.

Reading the Look of Love
How fast you can judge whether a person of the opposite sex is looking at you depends on how masculine or feminine they look, according to a new study. The researchers speculate that there may be an evolutionary advantage to quickly noticing when a hottie is looking at you. Psychologists have debated how we determine whether someone else is looking at us or not. One point of view is that "it's almost a geometric problem," says Benedict C. Jones, of the University of Aberdeen in Scotland – that people just look at the whites of the eyes and other features of the face, without being influenced by the face in general.

Can negativity save a failing marriage?
Newlyweds are almost always advised to be upbeat—to have positive expectations for their relationship, to put the best spin on their partner’s actions, and to forgive and forget. Marriage counselors also take (and preach) the view that positive attitudes and actions will strengthen a struggling marriage, even when a little negativity might be well-deserved. So why do half of all couples in therapy fail to save their marriages? Is it possible that this rose-tinted advice is bad advice, that positivity isn’t the cure-all for ailing unions after all?

Tool Manipulation is Represented Similary in the Brains of the Blind and the Sighted
Blind people think about manipulating tools in the same regions of the brain as do people who can see, according to a new study. The researchers say this adds to evidence that the brain has a fairly defined organization, while still being able to adapt to unusual conditions, such as not having any vision. When you look at a glass in front of you on the desk, it sets off a lot of reactions in your brain. Part of your brain categorizes it: "That's a glass!" Another part of the brain thinks about the glass's shape and size, its exact location, and what you would have to do with your hand and arm if you were going to reach out and grab it.

Does believing soothe the worried mind?
Religious beliefs date back at least 100,000 years. That’s the time when our Neanderthal cousins began burying their dead with weapons and tools—presumably prepping them for the world beyond the grave. And such beliefs persist today, with the vast majority of modern humans in every corner of the globe espousing some kind of religious conviction. But why? The antiquity and universality of belief suggest that it serves some fundamental psychological purpose, but what would that be? A small but growing number of psychological scientists have been exploring these questions, focusing on the idea that religious belief may be a natural consequence of the human mind at work.
