Not all aggressive children are aggressive for the same reasons, according to Penn State researchers, who found that some kindergartners who are aggressive show low verbal abilities while others are more easily physiologically aroused. The findings suggest that different types of treatments may be needed to help kids with different underlying causes for problem behavior.
"Aggressive responses to being frustrated are a normal part of early childhood, but children are increasingly expected to manage their emotions and control their behavior when they enter school," said Lisa Gatzke-Kopp, assistant professor of human development and family studies. "Kids who don't do this well, who hit their classmates when they are frustrated or cause other types of disturbances in the classroom, are at especially high risk for long-term consequences including delinquency, violence, dropping out of school, abusing substances and even suicide. Research tells us that the earlier we can intervene, the better the chances of getting these children back on track."
"This group of kids may be functioning at a cognitive level that is more akin to a preschooler than a kindergartner," Gatzke-Kopp said. "They have a harder time extracting what other people are feeling. They don't have a nuanced sense of emotions; everything is either happy or sad to them. So they might not be as good at recognizing how their behavior is making another child feel. They may literally have a hard time 'using their words,' so hitting becomes an easier solution when they are frustrated."
The second group of kids had good verbal and cognitive functioning, but they were more physiologically aroused. They were more emotionally reactive, and tended to have more stressors in their lives.
"These children may be able to tell you that if somebody pushed them on the playground they would go get a teacher, but the push happens and they kind of lose it and it doesn't matter what they should do, they just act on impulse," Greenberg said. "One possibility is that the threshold for managing frustration is quite low for these kids. So what we might consider a minor annoyance to them is a major threat. When they are calm they function very well, but when they lose control of their emotions, they can't control their behavior."
