Strong, secure relationships help stabilize children's behavior and provide the core guidance needed to build lifelong social skills. Children who grow up with such relationships learn healthy, appropriate emotional responses to everyday situations. But children raised in poor households often fail to learn these responses, to the detriment of their school performance. For example, students with emotional dysregulation may get so easily frustrated that they give up on a task when success was just moments away. And social dysfunction may inhibit students' ability to work well in cooperative groups, quite possibly leading to their exclusion by group members who believe they aren't "doing their part” or "pulling their share of the load.” This exclusion and the accompanying decrease in collaboration and exchange of information exacerbate at-risk students' already shaky academic performance and behavior.
