Behavioral Distinctions between Twins with and without Schizophrenia
According to E. Fuller Torrey in his 1994 study, the twin that goes on to develop schizophrenia was the one who was "abnormal" throughout life. Here are some distinctions made:
-
Symptomatic twin frequently weighed less at birth
-
Symptomatic twin had early development history that included more instances of physiological distress
-
Symptomatic twin was more submissive, tearful, and sensitive than other twin and viewed as more vulnerable by parents
-
Impaired motor coordination
In a 1991 study by Elaine Walker, these differences can be seen even by watching home videos of children.

Behavioral Distinctions between Twins with and without Schizophrenia
Research has found that if one identical twin develops schizophrenia, the other twin has about a 50% chance of also developing the disorder. However, if one fraternal twin develops schizophrenia, the other twin has only about a 17% chance. Based on these findings, what is the most accurate evaluation of the factors contributing to schizophrenia?
A large-scale study finds that if one identical twin is diagnosed with a specific psychological disorder, there is a 48% chance the other twin will also have the disorder. For fraternal twins, this chance is only 17%. Based on these findings, what is the most logical conclusion about the nature of this disorder?
