Quitting marshmallow test can be a rational decision Posted: 26 Mar 2013 04:41 PM PDT A psychological experiment known as "the marshmallow test" has captured the public's imagination as a marker of self control. This test shows how well children can delay gratification, a trait that has been shown to be as important to scholastic performance as traditional IQ. New research suggests, however, that changing one's mind about delaying gratification can be a rational decision in situations when the timing of the payoff is uncertain.

Saliva testing predicts aggression in boys Posted: 26 Mar 2013 01:21 PM PDT A new study indicates that a simple saliva test could be an effective tool in predicting violent behavior.

Protein-rich breakfasts prevent unhealthy snacking in the evening, study finds Posted: 26 Mar 2013 12:11 PM PDT Eating a breakfast rich in protein significantly improves appetite control and reduces unhealthy snacking on high-fat or high-sugar foods in the evening, which could help improve the diets of more than 25 million overweight or obese young adults in the U.S., new research finds.

Mindfulness improves reading ability, working memory, and task-focus Posted: 26 Mar 2013 10:33 AM PDT If you think your inability to concentrate is a hopeless condition, think again -- and breathe, and focus. According to a new study, as little as two weeks of mindfulness training can significantly improve one's reading comprehension, working memory capacity, and ability to focus.

Fruit flies fed organic diets are healthier than flies fed nonorganic diets, study finds Posted: 26 Mar 2013 09:17 AM PDT Fruit flies fed an organic diet recorded better health outcomes than flies fed a nonorganic diet, according to a new study. Researchers found that fruit flies raised on organic foods performed better on various health tests. Flies on organic diets showed improvements on the most significant measures of health, namely fertility and longevity, according to new research.

Women make better decisions than men, study suggests Posted: 26 Mar 2013 07:16 AM PDT Women's abilities to make fair decisions when competing interests are at stake make them better corporate leaders, researchers have found. The study showed that women are more likely to consider the rights of others and to take a cooperative approach to decision-making. This approach translates into better performance for their companies.

Human emotion: We report our feelings in 3-D Posted: 26 Mar 2013 07:10 AM PDT Like it or not and despite the surrounding debate of its merits, 3-D is the technology du jour for movie-making in Hollywood. It now turns out that even our brains use three dimensions to communicate emotions. According to a new study, the human report of emotion relies on three distinct systems: one system that directs attention to affective states ("I feel"), a second system that categorizes these states into words ("good", "bad", etc.); and a third system that relates the intensity of affective responses ("bad" or "awful"?).

Five year-olds who watch TV for three or more hours a day more likely to be antisocial: But the risk of this behaviour is very small Posted: 25 Mar 2013 05:25 PM PDT Five year-olds who watch TV for three or more hours a day are increasingly likely to develop antisocial behaviors, such as fighting or stealing by the age of seven, indicates new research.

Language acquisition: Nouns before verbs? Posted: 25 Mar 2013 03:40 PM PDT Researchers are digging deeper into whether infants' ability to learn new words is shaped by the language being acquired. A new study cites a promising new research agenda aimed at bringing researchers closer to discovering the impact of different languages on early language and cognitive development. Researchers have asked why infants learn new nouns more rapidly than new verbs, with many researchers asserting that the early noun-advantage is a universal feature of human language.
