The Nature vs. Nurture Debate and Feral Children
📌 Feral children, defined as those wild or undomesticated, serve as a natural experiment addressing the core scientific question: are humans a product of genes (nature) or experience (nurture)?
🐺 Stories like those of Romulus and Remus (raised by a wolf) or Tarzan highlight a primal fascination with the distinction between humans and animals.
🧠 Being raised by humans is considered a crucial part of human development; children raised without human interaction raise questions about their fundamental humanity.

Case Study: Oksana Malaya
🐶 Oksana Malaya, born in 1983, lived with dogs in a farm kennel for five years after being abandoned by alcoholic parents at age three.
🐕 Her survival mechanism involved adopting canine habits, resulting in her being more like a dog than a human child, including limited speech.
🗣️ The case illustrates that children can copy the habits of creatures they are surrounded by, reinforcing the power of immediate environment.

Historical Case: Victor of Aveyron (Early Scientific Study)
🌲 The scientific study of feral children began in 1800 with the capture of Victor in the woods of Southwest France, captivating Dr. Jean Itard.
❤️ Itard tested Victor's humanity based on the abilities to feel empathy and use language; initially, Victor possessed neither.
🤝 Progress was made through love and kindness provided by Dr. Itard and his housekeeper, Madame Guerin, especially when Victor demonstrated empathy by removing a place setting after Madame Guerin wept over her husband's death.
🗣️ Despite passing the empathy test, Victor failed to master language, leading Itard to lose interest after concluding that true humanity requires being sociable and language-using.

Experimental Reversal: Harlow and Kellogg Studies
🐒 Winthrop Kellogg attempted the "forbidden experiment" by raising a chimpanzee named Gua alongside his son, Donald, to prove nurture's dominance.
🙉 Gua learned human characteristics, but Donald started adopting chimpanzee vocalizations (barks and yelps), causing Kellogg to call off the experiment.
🧸 Harry Harlow’s monkey studies demonstrated the crucial importance of physical contact and emotional caregiving; infants chose soft, warm surrogate mothers over wire mothers offering milk, suffering devastating social effects from isolation.

Case Study: Genie Wiley
🔒 Genie was discovered at age 13, having spent 13 years in near total isolation—locked in a room or strapped to a potty chair—by her father, Clark Wiley.
👶 She was the size of a six-year-old, had no verbal skills, and was entirely dependent, exhibiting "feral child" properties despite her urban setting.
🧠 Neuroscientific evaluation showed that the cortex areas responsible for speech and language had physically diminished because they were never stimulated by speech input during critical periods.
📉 Despite intensive rehabilitation, Genie learned many words but stopped making progress in grammar, suggesting a cognitive deficiency specifically in the mental faculty for grammar, reinforcing the critical period hypothesis for language acquisition.

Case Study: Edek and Prognosis for Recovery
🐕 Edek, found at age 4 in Ukraine after being raised by stray dogs due to maternal neglect, exhibited classic dog behaviors like eating with his hands and scratching.
⬆️ Because Edek was identified younger (age 4) compared to Victor (age 8) or Oksana (age 8), his prognosis for language recovery is considered encouraging, with experts anticipating a "grammar burst."
🤝 Socially, Edek remains vulnerable due to his indiscriminate attachment to almost anyone following years of neglect, highlighting long-term social vulnerability.

Key Points & Insights
➡️ Feral children studies underscore that extreme neglect, even for a finite period, causes physical changes and diminished functionality in brain regions responsible for language and social skills.
➡️ The cases of Victor, Oksana, and Genie suggest that while empathy might be recoverable, mastering complex skills like language is profoundly tied to early environmental exposure (critical periods).
➡️ While some cases like Edek show significant positive recovery when intervention occurs earlier, others like Oksana and Genie demonstrate that irreversible developmental consequences often remain, meaning they may never achieve full societal integration.
➡️ These cases prompt awe, showing the resilience required to develop survival strategies under unimaginable conditions, while simultaneously driving science to better understand and prevent neglect-induced brain damage.
