(The Reis Group) Children who are bystanders to a bullying incident are more likely to intervene if their parents have given them advice to intervene and less likely to intervene if their parents tell them to 'stay out of it,' according to a new study published in the Journal of Clinical Child and Adolescent Psychology, a journal of the Society of Clinical Child and Adolescent Psychology.

In a new study, researchers for the first time have shown how different parts of the brain represent an object's location in depth compared to its 2-D location.
