Helicopter parenting can violate students' basic needs Posted: 12 Feb 2013 08:18 AM PST When is it time for parents to back away? A new study shows that college students with overcontroling parents are more likely to be depressed and less satisfied with their lives. This so-called helicopter parenting style negatively affects students' well-being by violating their need to feel both autonomous and competent. Parental overinvolvement may lead to negative outcomes in children, including higher levels of depression and anxiety. Studies also suggest that children of overinvolved or overcontroling parents may feel less competent and less able to manage life and its stressors. In contrast, evidence suggests that some parental involvement in children's lives facilitates healthy development, both emotionally and socially.

Teaching teens that people can change reduces aggression in school Posted: 12 Feb 2013 07:05 AM PST In eight studies involving more than 1,600 diverse 8th-10th grade students, researchers show that teenagers who believe people can't change react more aggressively to a peer conflict than those who think people can change. Following these studies, researchers developed a brief intervention that taught teens that people have the potential to change. The intervention reduced the teens' tendency to see the offense as having been done on purpose, and reduced their desire for aggressive revenge.

Differential parenting found to negatively affect whole family, even the favored child Posted: 12 Feb 2013 07:05 AM PST Parents act differently with different children -- for example, being more positive with one child and more negative with another. A new longitudinal study looking at almost 400 Canadian families has found that this behavior negatively affects not only the child who receives more negative feedback, but all the children in the family. The study also found that the more risks experienced by parents, the more likely they will treat their children differentially.

Negative stereotypes about boys hinder their academic achievement Posted: 12 Feb 2013 07:05 AM PST Researchers investigated the role of gender stereotypes. They found that from a very young age, children think boys are academically inferior to girls, and they believe that adults think so, too.
