Refrigerator mother
The term refrigerator mother was coined around 1950 as a label for mothers of autistic children. These mothers were often blamed for their children's atypical behaviors, which included rigid rituals, speech difficulty, and self-isolation.
The "refrigerator mother" label was based on the assumption  now discredited among a majority of, though not all, mental health professionals  that autistic behaviors stem from the emotional frigidity of the children's mothers. As a result, many mothers of autistic children suffered from blame, guilt, and self-doubt from the 1950s throughout the 1970s and beyond: when the prevailing medical belief that autism resulted from inadequate parenting was widely assumed to be correct. Present-day proponents of the psychogenic theory of autism continue to maintain that the condition is a result of poor parenting.

# Origins of theory
In his 1943 paper that first identified autism, Leo Kanner called attention to what appeared to him as a lack of warmth among the fathers and mothers of autistic children. In a 1949 paper, he suggested autism may be related to a "genuine lack of maternal warmth", noted that fathers rarely stepped down to indulge in children's play, and observed that children were exposed from "the beginning to parental coldness, obsessiveness, and a mechanical type of attention to material needs only.... They were left neatly in refrigerators which did not defrost. Their withdrawal seems to be an act of turning away from such a situation to seek comfort in solitude." In a 1960 interview, Kanner bluntly described parents of autistic children as "just happening to defrost enough to produce a child."
In the absence of any biomedical explanation for what causes autism after the telltale symptoms were first described by scientists, Bruno Bettelheim, a University of Chicago professor and child development specialist, and other leading psychoanalysts championed the notion that autism was the product of mothers who were cold, distant and rejecting, thus deprived of the chance to "bond properly". The theory was embraced by the medical establishment and went largely unchallenged into the mid-1960s, but its effects have lingered into the 21st century. Many articles and books published in that era blamed autism on a maternal lack of affection, but by 1964, Bernard Rimland, a psychologist with an autistic son, published a book that signaled the emergence of a counter-explanation to the established misconceptions about the causes of autism. His book, Infantile Autism: The Syndrome and its Implications for a Neural Theory of Behavior, attacked the "refrigerator mother" hypothesis directly.
Soon afterwards, Bettelheim wrote The Empty Fortress: Infantile Autism and the Birth of the Self, in which he compared autism to being a prisoner in a concentration camp:
"The difference between the plight of prisoners in a concentration camp and the conditions which lead to autism and schizophrenia in children is, of course, that the child has never had a previous chance to develop much of a personality."
Some authority was granted to this as well because Bettelheim had himself been interned at the Dachau concentration camp during World War II. The book was immensely popular and Bettelheim became a leading public figure on autism until his death, when it was revealed that Bettelheim plagiarized others' work and falsified his credentials. Also, three ex-patients questioned his work, characterizing him as a cruel tyrant.
Although Kanner was instrumental in framing the "refrigerator mother" theory, it was Bettelheim who facilitated its widespread acceptance by the public and the medical establishment cognoscenti in the 1950s and 1960s.
In 1969, Kanner addressed the "refrigerator mother" issue at the first annual meeting of what is now the Autism Society of America, stating:
From the very first publication until the last, I spoke of this condition in no uncertain terms as "innate."  But because I described some of the characteristics of the parents as persons, I was misquoted often as having said that "it is all the parents' fault."
This was somewhat a whitewashing of his own history. In many of his articles Kanner explicitly and clearly suggested that parental behavior can contribute to autism. But the renunciation of the idea by the person who originated it was seen as a decisive blow in any event.

# Other notable psychiatrists
For Silvano Arieti, who wrote his major works from the 1950s through the 70s, the terms autistic thought and what he called paleologic thought are apparently the same phenomenon.  Paleologic thought is a characteristic in both present-day schizophrenics and primitive men: a type of thinking that has its foundations in non Aristotelian logic.  An autistic child speaks of himself as "you" and not too infrequently of the mother as "I".  The "you" remains a"you" and is not transformed into "I".
For Margaret Mahler and her colleagues, autism is a defense of children who cannot experience the mother as the living primary-object. According to them, autism is an attempt at dedifferentiation and deanimation. The symbiotic autistic syndrome used to be called the "Mahler syndrome" because Mahler first described it: The child is unable to differentiate from the mother.
Arieti warned that an autistic tendency is a sign of a kind of disorder in the process of socialization, and that when autistic expressions appear it should be assumed that there is a sort of difficulty between the child and his parents, especially the schizogenic mother.  Children who use autistic expressions, Arieti observes, are children who cannot bond socially.
In Interpretation of Schizophrenia Arieti maintained that for a normal process of socialization, it is necessary for the parent-child relations to be normal.  Loving or non-anxiety parental attitudes favor socialization. Arieti not only maintained that the parent-child relations are the first social act and the major drive of socialization, but also a stimulus to either accept or reject society. The childs self in this view is a reflection of the sentiments, thoughts, and attitudes of the parents toward the child.  Autistic children show an extreme socializing disorder and do not want any sort of relationship with people.  They "eliminate" people from their consciousness.  For Arieti the fear of the parents is extended to other adults: a tendency to cut off communication with human beings.

# Persistence of the theory
According to Peter Breggins Toxic Psychiatry, the psychogenic theory of autism was abandoned for political pressure from parents organizations; not for scientific reasons. For example, some case reports have shown that profound institutional privation can result in quasi-autistic symptoms. Clinician Frances Tustin devoted her life to the theory. She wrote:
Alice Miller, one of the best-known authors of the consequences of child abuse, has maintained that autism is psychogenic, and that it is fear of the truth about child abuse the leitmotif of nearly all forms of autistic therapy known to her.  When Miller visited several therapy centers for autism in the United States, it became apparent to her that the stories of children "inspired fear in both doctors and mothers alike":
Like Arieti and Tustin, Miller believes that only empathetic parental attitudes lead to the complete blossoming of the childs personality.
Despite the current genetic research on autism and autism-related conditions, the "refrigerator mother" theory, widely discarded in the United States, still has some support in Europe and is largely believed to be the cause of autism in South Korea.
