I was unable to find any research examining the relationship between children and road rage. However, the relationship is not that far-fetched, because children learn by example. Social learning theory is based on the principle that children become socialized by interacting with others and will model behaviors they observe. Under this behavioral model, children who are exposed to road rage, are more likely to perpetuate that behavior when, they, themselves begin to drive. Our aggressiveness generally is not due to a lack of control, but unconsciousness.
Some people use tests find out if they are road rage denial.
The self-witnessing exercise calls for drivers to observe their unconscious and actions while driving, by talking into a tape recorder as they drive. Most participants are shocked at the what they say and do while driving. Although adults may not be aware of their actions, children are highly perceptive and synthesize what they observe. In a report by Kendra Morgan, she practiced self-witnessing with a small child. The activity illustrated just how observant children can be.
