Answer:
Preoperational stage of Piaget's cognitive development.
Explanation:
When asked where the sun goes at night, four-year-old Kiet explains to his dad that it goes to sleep. Later that day, Kiet gets upset because he believes his sister's glass contains more juice than his glass. Both glasses actually contain the same amount of juice, but Kiet is confused because of the tall and thin shape of his sister's glass. From these instances, we can say that Kiet is in the pre-operational stage of Piaget's cognitive development.
Answer:
Mia and David exemplify characteristics associated with Social Psychology
Explanation:
Social psychology is a scientific study that deals with how human behavior is influenced by other people in a particular social context. For example, Mia in the question wears a skirt, loves shopping and has no problems with having long hair because her social circle comprises girls who exhibit the same traits. Likewise, David loves sporting and participating in aggressive activities because boys in his social circle do the same. You can see that in both cases, Mia and David's behavior are influenced by their peers (social context).
