The temperament mix between parents and children also affects family life. For example, a slow-paced parent may be irritated by a highly active child; or if both parent and child are highly active and intense, conflict could result. This knowledge can help parents figure out how temperaments affect family relationships. What may appear to be a behavioral problem may actually be a mismatch between the parent's temperament and their child's. By taking a closer look at the nine traits that Thomas and Chess revealed from their study, parents can gain a better understanding of their child's temperament and their own. Parents may also notice that situational factors cause a child's temperament to seem problematic; for example, a child with low rhythmicity can cause difficulties for a family with a highly scheduled life, and a child with a high activity level may be difficult to cope with if the family lives in a crowded apartment upstairs from sensitive neighbors.
