Soccer: le secret des tirs de barrage
Metro Montreal: Au lendemain de la défaite des États-Unis contre le Japon en tirs de barrage dimanche en finale de la Coupe du monde de soccer féminin, il est de bon ton de se pencher sur une étude qui affirme que les gardiens de but ont tendance à plonger à droite plus souvent quand leur équipe tire de l’arrière durant une fusillade. Pendant les tirs au but, les Américaines n’ont fait mouche qu’une fois en quatre tentatives, tandis que les Japonaises ont marqué trois fois sur quatre frappes. Or, à chacun des quatre tirs nippons, la gardienne américaine s’est lancée vers la droite… Intéressant. Lire plus: Metro Montreal

Work Engagement, Job Satisfaction, and Productivity—They’re a Virtuous Cycle
Engaged workers—those who approach their work with energy, dedication, and focus—are more open to new information, more productive, and more willing to go the extra mile. Moreover, engaged workers take the initiative to change their work environments in order to stay engaged. What do we know about the inner workings of work engagement, and how can employers enhance it to improve job performance? In a new article to be published in the August issue of Current Directions in Psychological Science , a journal of the Association for Psychological Science, Arnold B. Bakker creates a model of work engagement based on the best current research.

Internet search engines cause poor memory, scientists claim
The Telegraph: Researchers found increasing number of users relied on their computers as a form of “external memory” as frequent use of online information libraries "wired" human brains. The study, examining the so-called "Google effect", found people had poor recall of knowledge if they knew where answers to questions were easily found. The scientists from Columbia University, in New York, found people were increasingly bypassing discussions with friends to use the internet as their main source of information.

Does Virginity Really Protect Against Risky Sex Later On?
The Huffington Post: True Love Waits is a virginity pledge program, probably the largest of its kind. Started by the Southern Baptist Convention in 1993, it now claims more than 2.5 million members, teenagers and young adults who have promised to remain sexually "pure" until marriage. Many other virginity pledge programs have sprouted up since the '90s, and what's more, state lawmakers have jumped on the abstinence bandwagon. Thirty four states now require that abstinence be taught or emphasized in the school curricula, while only 15 mandate instruction in contraception. Read more: The Huffington Post

Baby Blur: Infants’ Eyes Take Longer to Process Movement
LiveScience: Rapidly changing images may look like a blur to infants, according to a new study. Although babies can see the movement, they may not be able to identify the individual elements within a moving scene as well as an adult can. Babies' brains gradually develop the ability to use visual information to discover and process their world. Researchers found that the speed limit at which babies can recognize individual moment-to-moment changes is about half a second. That's about 10 times slower than for adults, who can recognize rapid, individual changes that occur 50 to 70 milliseconds or slower.

Time and Numbers Mix Together in the Brain
Clocks tell time in numbers—and so do our minds, according to a new study which will be published in an upcoming issue of Psychological Science, a journal of the Association for Psychological Science. In two experiments, scientists found that people associate small numbers with short time intervals and large numbers with longer intervals—suggesting that these two systems are linked in the brain. It’s clear that time and numbers are related in daily life, says Denise Wu of National Central University of Taiwan, who cowrote the new study with Acer Chang, Ovid Tzeng, and Daisy Hung.
