How do children develop an understanding of these domains and the distinctions between them?

As children interact with others and observe the consequences of their actions, they gradually develop a more sophisticated understanding of differences among the domains (Nucci, 2009; Turiel, 2008a, 2008b; Parke & Clarke-Steward, 2011). For example, when children push a classmate down on the playground, they see the impact of their actions on others, and they are often reprimanded by adults. They also begin to realise that conventions are arbitrary and situation specific, which can result in their questioning both school regulations and rules at home.
