Final answer:
Stranger anxiety is a fear of unfamiliar people exhibited by children. Xenophobia is the irrational fear or hatred of another culture.
Step-by-step explanation:
Stranger anxiety is a common phenomenon observed in children around the time they develop object permanence. It is a fear of unfamiliar people and can be exhibited through behaviors such as crying, turning away, or clinging to a caregiver. This fear arises when a child is unable to fit the stranger into their existing understanding or schema.
In addition, the irrational fear or hatred of another culture is known as xenophobia. Xenophobia is characterized by an intense dislike, fear, or prejudice against people from other cultures or who are perceived as strangers.
