Which theory was disproved by 1970 regarding the cause of ASD?

• A. Poor early father-child relationships
• B. Poor early mother-child relationships
• C. Genetic predisposition
• D. Environmental toxins

Answer: (B)

The belief in poor early mother-child relationships as a primary cause of Autism Spectrum Disorders (ASD) was rooted in the theory of "refrigerator mothers" that gained popularity in the mid-20th century. This theory suggested that a lack of maternal warmth and affection led to the development of autism in children. However, by the 1970s, research and clinical evidence began to challenge and ultimately disprove this notion. Studies demonstrated that autism was not a result of maternal behavior but was more complex, involving neurological and genetic factors.

This shift in understanding led to a more compassionate view of the disorder, pivoting away from blaming parents for their child's condition. Instead, focus shifted towards understanding autism as a developmental disorder with diverse causes, most notably highlighting genetic factors, brain structure anomalies, and other biological influences as contributing to the onset of autism.

The disproval of the "refrigerator mother" theory marked an important turning point in the field of autism research, helping to pave the way for a more comprehensive approach to understanding and addressing the needs of individuals with ASD.
