Researchers find that primary school children with reduced cognitive skills for planning and self-restraint are more likely to show increased aggression in middle childhood. The study examined the relationship between aggression and executive function -- a measure of cognitive skills that allow a person to achieve goals by controlling their behavior. The results suggest that helping children to increase their executive function could reduce their aggression.

The emotional and sexual abuse that some children endure can lead them to commit crimes later in life. But when children achieve good grades and don't skip school, the likelihood of self-reported, chronic criminal behaviors declines significantly.

An new study finds the brain network that controls theory of mind has already formed in children as young as 3. The study is the first to use functional magnetic resonance imaging (fMRI) to scan the brains of children that young as they perform a task requiring the ability to make inferences about someone else's state of mind.

A new study indicates that university education has a dramatically positive effect on the development of non-cognitive skills like conscientiousness, extraversion and agreeableness, in addition to the expected intellectual benefits. The paper also shows that the impact of education on these skills is even more dramatic for students from lower socioeconomic backgrounds.

Scientists have long known that sleep is important to the formation and retention of new memories. Memory consolidation is associated with sudden bursts of oscillatory brain activity, called sleep spindles, which can be visualized and measured on an electroencephalogram (EEG). Now researchers have found that sleep spindles also play a role in strengthening new memories when newly learned information is played back to a person during sleep.

One in five teachers who were the victims of physical or verbal violence at their schools didn't report the incidents to school administrators, according to a nationwide study. The results showed that significant minorities of teachers who experienced violence also didn't tell their colleagues (14 percent) or family (24 percent).

A significant part of working memory training effects is a result of a fast development of task-specific strategies during training, rather than an increase in working memory capacity.

The ability of the brain to synchronize with the tone and intonation of speech influences how language is processed. Study results could help design more effective activities to train the brain in order to avoid future disorders such as dyslexia. Over the years, several neuro-scientific studies have shown that the auditory regions of the brain synchronize with external auditory stimuli. That is to say, the brain is able to naturally adjust the frequency of its brain waves with the oscillations or the rhythm of what it listens at each moment.

When a task calls for intuitive, its complexity goes unnoticed. However, when intuitions are not mobilized, the task is considered difficult, and seemingly requires the use of specific educational strategies. Researchers have demonstrated that teachers struggle to understand the difficulties encountered by pupils when attempting to solve apparently intuitive problems that are in fact difficult. The findings suggest that teachers only use their pedagogical skills when a problem seems to mobilize counter-intuitive strategies.

How can you convince elementary school students to consume more fruit and vegetables? Scientists have found that school fruit schemes can actually help to achieve this goal. If children receive fruit and vegetables free of charge in their schools several times a week, they consume considerably more of this food group, which is often less popular with children, even on days without school fruit distribution.

A simple, low-cost experiment to encourage women to enter the male-dominated field of economics was surprisingly effective, says an economist. Top female college students were inspired to pursue economics when exposed very briefly to charismatic, successful women in the field. The successful results suggest that exposing young women to an inspiring female role model could spark similar interventions in other male-dominated fields of study to enhance gender diversity.

There's nothing wrong with being a little weird.

Researchers have developed a new system to reduce the time it takes to grow these brain models, which will give them the ability to screen drugs and study what's behind disease-causing mutations more quickly.

Neuroscientists have shown how amputees can learn to control a robotic arm through electrodes implanted in the brain. The research details changes that take place in both sides of the brain used to control the amputated limb and the remaining, intact limb. The results show both areas can create new connections to learn how to control the device, even several years after an amputation.
