Who were Isabelle and Genie?

Isabelle and Genie were both subjects of significant cases in psychological research on language acquisition and social development. Isabelle, a girl isolated with her deaf-mute mother until the age of six, was able to develop language skills rapidly after being discovered and given appropriate support. Genie, on the other hand, was a girl who endured severe social isolation and abuse, being found at age 13, which severely impacted her language development and social skills. Their cases highlight the critical importance of social interaction and language exposure in early childhood development.
