Answer:
The statement is true.
During middle childhood (between 6 and 11 years old), children's development allows them to become increasingly independent and self-regulated. They begin to understand the concept of rules and how they apply to different situations. They also start to internalize values and beliefs about what is right and wrong, and this internalization allows them to regulate their behavior without the need for external rewards or punishments.
For example, a 7-year-old child may start to understand that it is wrong to hit another child, even if an adult is not present to intervene. They may have learned this through previous experiences or from adults who have taught them this rule. As a result, they will regulate their behavior and choose not to hit the other child, even if there is no immediate reward or punishment for doing so.
Overall, as children progress through middle childhood, they become more capable of self-regulation and less reliant on external rewards and punishments to guide their behavior.
