Why are some kids easily able to keep listening to a teacher when their friends are chatting, refrain from blurting out an answer or get started on their homework instead of playing?The ability to pay attention, manage impulses and to intentionally start a behavior are all examples of self-regulation. Children vary widely in their ability to regulate their behaviors, and a new study from the Arizona State University Department of Psychology has shown that genetics and the actions of mothers and fathers all play a role in how self-regulation differs across kids.
