Social Domain Theory (SDT) Turiel is a psychological theory that aims to explain how children and adults reason about different social issues. According to this theory, people categorize social situations into different domains based on the values and principles that are considered important in that particular situation. These domains include moral, social-conventional, and personal domains.

The moral domain involves issues related to the harm and well-being of others, such as stealing or physical violence. The social-conventional domain includes norms and rules that are created by society, such as dress codes or table manners. Lastly, the personal domain involves individual preferences and choices that do not affect others, such as choosing what clothes to wear or food to eat.

SDT Turiel proposes that individuals have different criteria for evaluating behavior in each of these domains. For instance, actions in the moral domain are often judged based on whether they cause harm or benefit others. In contrast, actions in the social-conventional domain are evaluated based on whether they conform to established norms or rules.

Research has shown that children as young as 2 years old can distinguish between these domains and apply different criteria for evaluating behavior within them. However, children’s understanding of these domains becomes more sophisticated with age and experience.

One of the key contributions of SDT Turiel is its emphasis on cultural variability in how people classify social situations into different domains. For example, some cultures may emphasize individual rights more than others when evaluating behavior in the moral domain.

In addition to cultural variability, SDT Turiel has also been applied to understanding individual differences in moral reasoning. For instance, some researchers have found that individuals who endorse more collectivistic values tend to prioritize group harmony over individual rights when making moral judgments.

Overall, Social Domain Theory Turiel provides a useful framework for understanding how people reason about different social issues. By recognizing the importance of context-specific values and principles when making evaluations about behavior, this theory can help us better understand the complexities of moral reasoning.
