There have been a number of cases of feral children raised in social isolation with little or no human contact. Few have captured public and scientific attention like that of a young girl called Genie Wiley. She spent almost her entire childhood locked in a bedroom, isolated and abused for over a decade.

Genie's case was one of the first to put the critical period theory to the test. Could a child reared in utter deprivation and isolation develop language? Could a nurturing environment make up for a horrifying past?

This article discusses Genie's life, her treatment, and the impact that abuse and deprivation had on her language development. It also covers the ethical problems with her case.

Genie's Story

In order to understand Genie's story, it is important to look at what is known about her early life, the discovery of the abuse she had endured, and the subsequent efforts to treat and study her.

Early Life (1957-1970)

Genie's life prior to her discovery was one of utter deprivation. She spent most of her days tied naked to a potty chair, only able to move her hands and feet. When she made noise, her father would beat her. The rare times her father did interact with her, it was to bark or growl. Genie Wiley's brother, who was five years older than Genie, also suffered abuse under their father.

Discovery and Study (1970-1975)

Genie's story came to light on November 4, 1970, in Los Angeles, California. A social worker discovered the 13-year old girl after her mother sought out services for her own health. The social worker soon discovered that the girl had been confined to a small room, and an investigation by authorities quickly revealed that the child had spent most of her life in this room, often tied to a potty chair.

A Genie Wiley documentary was made in 1997 called "Secrets of the Wild Child." In it, Susan Curtiss, PhD, a linguist and researcher who worked with Genie, explained that the name Genie was used in case files to protect the girl's identity and privacy.

Susan Curtiss, PhD

"The case name is Genie. This is not the person's real name, but when we think about what a genie is, a genie is a creature that comes out of a bottle or whatever but emerges into human society past childhood. We assume that it really isn't a creature that had a human childhood.”

— Susan Curtiss, PhD

Both parents were charged with abuse, but Genie's father died by suicide the day before he was due to appear in court, leaving behind a note stating that "the world will never understand."

The story of Genie's case soon spread, drawing attention from both the public and the scientific community. The case was important, said psycholinguist and author Harlan Lane, PhD, because "our morality doesn’t allow us to conduct deprivation experiments with human beings; these unfortunate people are all we have to go on."

With so much interest in her case, the question became what should be done to help her. A team of psychologists and language experts began the process of rehabilitating Genie.

The National Institute of Mental Health (NIMH) provided funding for scientific research on Genie’s case. Psychologist David Rigler, PhD, was part of the "Genie team" and he explained the process.

David Rigler, PhD

"I think everybody who came in contact with her was attracted to her. She had a quality of somehow connecting with people, which developed more and more but was present, really, from the start. She had a way of reaching out without saying anything, but just somehow by the kind of look in her eyes, and people wanted to do things for her.”

— David Rigler, PhD

Genie's rehabilitation team also included graduate student Susan Curtiss and psychologist James Kent. Upon her initial arrival at UCLA, Genie weighed just 59 pounds and moved with a strange "bunny walk." She often spat and was unable to straighten her arms and legs. Silent, incontinent, and unable to chew, she initially seemed only able to recognize her own name and the word "sorry."

After assessing Genie's emotional and cognitive abilities, Kent described her as "the most profoundly damaged child I've ever seen … Genie's life is a wasteland." Her silence and inability to use language made it difficult to assess her mental abilities, but on tests, she scored at about the level of a one-year-old.

She soon began to make rapid progression in specific areas, quickly learning how to use the toilet and dress herself. Over the next few months, she began to experience more developmental progress but remained poor in areas such as language. She enjoyed going out on day trips outside of the hospital and explored her new environment with an intensity that amazed her caregivers and strangers alike.

Curtiss suggested that Genie had a strong ability to communicate nonverbally, often receiving gifts from total strangers who seemed to understand the young girl's powerful need to explore the world around her.

Psychiatrist Jay Shurley, MD, helped assess Genie after she was first discovered, and he noted that since situations like hers were so rare, she quickly became the center of a battle between the researchers involved in her case. Arguments over the research and the course of her treatment soon erupted. Genie occasionally spent the night at the home of Jean Butler, one of her teachers.

After an outbreak of measles, Genie was quarantined at her teacher's home. Butler soon became protective and began restricting access to Genie. Other members of the team felt that Butler's goal was to become famous from the case, at one point claiming that Butler had called herself the next Anne Sullivan, the teacher famous for helping Helen Keller learn to communicate.

Eventually, Genie was removed from Butler's care and went to live in the home of psychologist David Rigler, where she remained for the next four years. Despite some difficulties, she appeared to do well in the Rigler household. She enjoyed listening to classical music on the piano and loved to draw, often finding it easier to communicate through drawing than through other methods.


After Genie was discovered, a group of researchers began the process of rehabilitation. However, this work also coincided with research to study her ability to acquire and use language. These two interests led to conflicts in her treatment and between the researchers and therapists working on her case.

State Custody (1975-Present)

NIMH withdrew funding in 1974, due to the lack of scientific findings. Linguist Susan Curtiss had found that while Genie could use words, she could not produce grammar. She could not arrange these words in a meaningful way, supporting the idea of a critical period in language development.

Rigler's research was disorganized and largely anecdotal. Without funds to continue the research and care for Genie, she was moved from the Riglers' care.

In 1975, Genie returned to live with her birth mother. When her mother found the task too difficult, Genie was moved through a series of foster homes, where she was often subjected to further abuse and neglect.

Genie’s situation continued to worsen. After spending a significant amount of time in foster homes, she returned to Children’s Hospital. Unfortunately, the progress that had occurred during her first stay had been severely compromised by the subsequent treatment she received in foster care. Genie was afraid to open her mouth and had regressed back into silence.

Genie’s birth mother then sued the Children’s Hospital of Los Angeles and the research team, charging them with excessive testing. While the lawsuit was eventually settled, it raised important questions about the treatment and care of Genie. Did the research interfere with the girl's therapeutic treatment?

Psychiatrist Jay Shurley visited her on her 27th and 29th birthdays and characterized her as largely silent, depressed, and chronically institutionalized. Little is known about Genie's present condition, although an anonymous individual hired a private investigator to track her down in 2000 and described her as happy. But this contrasts with other reports.

Genie Wiley Today

Today, Genie Wiley's whereabouts are unknown; though, if she is still living, she is presumed to be a ward of the state of California, living in an adult care home. As of 2022, Genie would be 65 years old.

Genie and Language Development

Part of the reason why Genie's case fascinated psychologists and linguists so deeply was that it presented a unique opportunity to study a hotly contested debate about language development.

Essentially, it boils down to the age-old nature versus nurture debate. Does genetics or environment play a greater role in the development of language?


Nativists believe that the capacity for language is innate, while empiricists suggest that environmental variables play a key role. Nativist Noam Chomsky suggested that acquiring language could not be fully explained by learning alone.

Instead, Chomsky proposed that children are born with a language acquisition device (LAD), an innate ability to understand the principles of language. Once exposed to language, the LAD allows children to learn the language at a remarkable pace.

Critical Periods

Linguist Eric Lenneberg suggests that like many other human behaviors, the ability to acquire language is subject to critical periods. A critical period is a limited span of time during which an organism is sensitive to external stimuli and capable of acquiring certain skills.

According to Lenneberg, the critical period for language acquisition lasts until around age 12. After the onset of puberty, he argued, the organization of the brain becomes set and no longer able to learn and use language in a fully functional manner.

Genie's case presented researchers with a unique opportunity. If given an enriched learning environment, could she overcome her deprived childhood and learn language even though she had missed the critical period?

If Genie could learn language, it would suggest that the critical period hypothesis of language development was wrong. If she could not, it would indicate that Lenneberg's theory was correct.

Despite scoring at the level of a 1-year-old upon her initial assessment, Genie quickly began adding new words to her vocabulary. She started by learning single words and eventually began putting two words together much the way young children do. Curtiss began to feel that Genie would be fully capable of acquiring language.

Genie's Language Development

After a year of treatment, she even started putting three words together occasionally. In children going through normal language development, this stage is followed by what is known as a language explosion. Children rapidly acquire new words and begin putting them together in novel ways.

Unfortunately, this never happened for Genie. Her language abilities remained stuck at this stage and she appeared unable to apply grammatical rules and use language in a meaningful way. At this point, her progress leveled off and her acquisition of new language halted.

While Genie was able to learn some language after puberty, her inability to use grammar (which Chomsky suggests is what separates human language from animal communication) offers evidence for the critical period hypothesis.

Of course, Genie's case is not so simple. Not only did she miss the critical period for learning language, but she was also horrifically abused. She was malnourished and deprived of cognitive stimulation for most of her childhood.

Researchers were also never able to fully determine if Genie had any pre-existing cognitive deficits. As an infant, a pediatrician had identified her as having some type of mental delay. So researchers were left to wonder whether Genie had experienced cognitive deficits caused by her years of abuse or if she had been born with some degree of intellectual disability.

Ethics Concerns

There are many ethical concerns surrounding Genie's story. Arguments among those in charge of Genie's care and rehabilitation reflect some of these concerns.

"If you want to do rigorous science, then Genie's interests are going to come second some of the time. If you only care about helping Genie, then you wouldn't do a lot of the scientific research," suggested psycholinguist Harlan Lane in the NOVA documentary focused on her life.

In Genie's case, the role of researcher and therapist were combined in one person. While Genie's story may be studied for its implications in our understanding of language acquisition and development, it is also a case that will continue to be studied over its serious ethical issues.

"I think future generations are going to study Genie's case not only for what it can teach us about human development but also for what it can teach us about the rewards and the risks of conducting 'the forbidden experiment,'" Lane explained.

Frequently Asked Questions

  • Where is Genie Wiley now?

    Genie, now in her 60s, is believed to be living in an adult care facility in California. Efforts by journalists to learn more about her location and current condition have been rejected by authorities due to confidentiality rules. Curtiss has also reported attempting to contact Genie without success.

  • Why wasn’t Genie Wiley’s mother prosecuted?

    Along with her husband, Irene Wiley was charged with abuse, but these charges were eventually dropped. Irene was blind and reportedly mentally ill, so it is believed that Genie's father was the child's primary caretaker. Genie's father, Clark Wiley, also abused his wife and other children. Two of the couple's children died in infancy under suspicious circumstances.

  • What have we learned from Genie Wiley?

    Genie's story suggests that the acquisition of language has a critical period of development. Her case is complex, however, since it is unclear if her language deficits were due to deprivation or if there was an underlying mental disability that played a role. The severe abuse she experienced may have also affected her mental development and language acquisition.

A Word From Verywell

Genie Wiley's story perhaps leaves us with more questions than answers. Though it was difficult for Genie to learn language, she was able to communicate through body language, music, and art once she was in a safe home environment. Unfortunately, we don't know what her progress could have been had adequate care not been taken away from her.

Genie's story raises questions about how we can better address the needs of child abuse survivors, as well as how we can learn from them without exploiting their cases or disrupting their care.
