Final answer:
Rough-and-tumble play is not exclusive to children in the United States and is observed in different cultures and countries.
Step-by-step explanation:
The statement 'Rough-and-tumble play is found almost exclusively among children living in the United States' is False. Rough-and-tumble play, which involves physical play such as wrestling, chasing, and play-fighting, is not exclusive to children in the United States. It is observed in children across different cultures and countries. For example, research on children's play behavior in various societies has shown that rough-and-tumble play exists in cultures such as the Aka people of Central Africa, the Taira people of Indonesia, and the Trobriand Islanders of Papua New Guinea. It is a universal behavior among children, reflecting their need for physical play and social interaction.
