问答题
Social Referencing
Social referencing is a process in which infants seek out and interpret the emotional responses from their parents to form their own emotional understanding of unfamiliar events, objects, or people. The concept of social referencing in children has been the subject of increasing studies over the last quarter of a century, as developmental psychologists seek to understand the formation of emotion in infants and children. Researches in this area have sought to understand how children learn to respond emotionally to various events, how they learn to interpret emotional responses of others, and how they form ideas about appropriateness of emotional displays.
Question: The professor uses two experiments to illustrate the definition of "social referencing". Explain how the two experiments are related to the reading passage.
