Genie's Case Study

Aug 19, 2025

Overview

This lecture explores the case of Genie, a girl who suffered extreme childhood isolation and abuse, and examines her subsequent rehabilitation and its implications for language development and psychology.

Discovery and Rescue of Genie

  • Genie was discovered in 1970 by social workers after her mother accidentally entered the wrong welfare office.
  • At age 13, Genie appeared much younger, was underweight, mute, incontinent, and had severe medical and developmental issues.
  • Genie had been kept isolated in a dark room, restrained, and deprived of social, emotional, and sensory stimulation.

Background and Abuse

  • Genie’s father, Clark Wiley, was deeply troubled by his own abusive upbringing and became increasingly paranoid and violent.
  • Genie’s family lived in severe isolation, with Clark forbidding communication and abusing both his wife and children.
  • Genie was kept restrained on a potty chair for most of her life, with minimal human interaction or stimulation.
  • Clark committed suicide before trial; Irene, Genie's mother, was found to be a victim herself and was not charged.

Rehabilitation and Study

  • Genie was made a ward of the state and became the subject of a major scientific study from 1971 to 1975, funded by the National Institute of Mental Health.
  • A multidisciplinary team worked on Genie's medical, psychological, and linguistic rehabilitation.
  • Genie showed rapid progress in vocabulary, social skills, sign language, and some cognitive tasks, but struggled with grammar and sentence structure.
  • Her case supported the critical period hypothesis: after puberty, acquiring complex grammar becomes extremely difficult.

Ethical Concerns and Later Life

  • Researchers struggled between caring for Genie’s well-being and pursuing scientific knowledge.
  • Genie lived with various team members, leading to conflicts of interest and ethical issues.
  • Genie's progress halted after being placed in foster homes, and she regressed due to further mistreatment.
  • Genie's later whereabouts are largely unknown; as of 2008, she was believed to be living in an assisted care facility.

Key Terms & Definitions

  • Critical Period Hypothesis — theory that language must be acquired before puberty for full fluency.
  • Social Isolation — lack of social interactions, leading to cognitive, emotional, and developmental deficits.
  • Neuroplasticity — the brain's ability to reorganize and form new connections, especially during learning or after injury.
  • Object Permanence — understanding that objects continue to exist even when not seen.
  • Deferred Imitation — ability to reproduce a behavior observed at an earlier time.

Action Items / Next Steps

  • Review the critical period hypothesis and its implications for language acquisition.
  • Consider ethical issues in research involving vulnerable populations.
  • Prepare questions on the effects of deprivation for class discussion.
