A new study finds that undermatching -- when high-performing students, often from economically-disadvantaged households, attend less competitive colleges than their qualifications permit -- correlates to another higher education dilemma: delayed graduation. The study shows that students who undermatch are less likely to graduate college within four or six years compared to peers who do not undermatch.

Researchers have found that children who participate in gun safety programs do not retain the skills they learned and that most still will approach a firearm in an unsupervised setting. While confirming that such programs are still essential, they stress that parents are the front line of defense when it comes to safeguarding their children from accidental shootings -- and that they cannot rely on safety training alone.

Children with brain injuries face significant challenges when transitioning from hospital or home to school where they face issues such as lack of educator understanding and catching up with missed work. Leading researchers in the field of pediatric brain injury from across the globe identify today's key issues in supporting children and youth with brain injuries as they transition to school or college.

For human beings to function socially, they need to be able to perceive, understand, and talk about others' mental states, such as beliefs, desires and intentions. There is no consensus among researchers as to when children develop this ability. Previous research indicates that it emerges around the age of four, but research shows that children can demonstrate this ability earlier - within social situations that they experience together with an engaged adult.

Children with autism may be at greater risk of bullying because they are more willing to accept unfair behavior, say psychologists. Children played trading games with a puppet and those with autism were 37 percent less likely to reciprocate fair offers and three times more likely to accept unfair offers of just one sticker. They may be particularly susceptible to bullies exploiting their lower concern for personal gain and their increased tolerance of unfair behavior.

One of the most important factors in ensuring student success is quality instruction by teachers. However, quality instruction can be a difficult goal if teachers do not have the resources to improve their skills and if rising levels of teacher stress go unchecked. Now, researchers have found that high levels of job-related stress affect 93 percent of teachers, a greater percentage than previously thought. Classrooms with highly stressed teachers tend to have the poorest student outcomes, such as lower grades and frequent behavior problems.

Researchers have found a positive relationship between midday-napping and nighttime sleep. They believe it might be key to boosting neurocognitive function in early adolescents. The team examined adolescents in Jintan, China, measuring midday napping, nighttime sleep duration and sleep quality, and performance on multiple neurocognitive tasks. Habitual nappers (who napped more often) tended to have a better nighttime sleep.

Establishing friendships in the university context helps students to gain independence and to manage their lives in their new environment with more self-confidence. For this reason, those who were more rooted in the village or town that they came from were more likely to experience difficulties adapting to university life. Although they keep some of the original support figures in their lives, it is important to build new relationships.

The goal of brain implants is to read neuron activity and respond by activating neurons to, for example, move prosthetics or simulate lost perceptions. Researchers have developed a device to do that, projecting a holographic image into the top layer of the brain to activate dozens of neurons hundreds of times a second to simulate real patterns of activity. Equipped with new, fast on/off optogenetic switches, neurons are tricked into perceiving things not there.

Scientists have previously shown that when one animal watches another performing a motor task, such as reaching for food, mirror neurons in the motor cortex of the observer's brain start firing as though the observer were also reaching for food.

There's nothing wrong with being a little weird. Because we think of psychological disorders on a continuum, we may worry when our own ways of thinking and behaving don't match up with our idealized notion of health.

Pain is essential for survival. However, it could also slow rehabilitation, or could become a distinct disorder. How strongly we feel it depends on our individual pain threshold.
