• Historical EvidenceThe account by Salimbene de Adam highlights that babies require not just physical care but also emotional and linguistic nurturing to thrive.
• Rene Spitz's ResearchIn the 1940s, Spitz's study showed that infants in a foundling home, despite being well-fed, suffered severe developmental issues due to lack of human interaction, leading to high mortality rates.
• Genie's CaseThe story of Genie, a girl raised in isolation, illustrates the lasting impact of language deprivation. Although she learned vocabulary, she could not grasp grammar, missing the critical period for language development.

🧠 Lessons

• Language is Essential for DevelopmentChildren need language and social interaction to develop properly; it is not merely a tool for communication but a fundamental aspect of human existence.
• The Critical PeriodThere is a crucial window for language acquisition in early childhood, after which it becomes significantly harder to learn language structures.
• Identity FormationLanguage shapes our thoughts, memories, and identities. Without it, individuals may struggle to form a coherent sense of self.
• Cultural ContextThe idea of a "pre-cultural self" is a myth; our identities are constructed through the language and interactions we experience from birth.
