On 65438+February 1 1 day, the Jiangge case was heard. Chen Shifeng, the murderer, and Liu Xin, the witness, held their own words, and the result was confusing. On the first day of the trial, Chen Shifeng's calm performance was somewhat surprising. He even looked directly at the mother of the victim Jiang Ge for 30 seconds, and the perilla in his heart made people shudder. Some netizens even put forward the view of anti-social personality.
What is antisocial personality?
Antisocial personality disorder, also known as emotionless personality disorder or social pathology, is the most serious type of antisocial disease. The prevalence rate is 4.3-9.4% in developed countries and 0.3% in Taiwan Province province.
How to diagnose antisocial personality disorder?
Anti-social personality disorder is characterized by high aggression, lack of sense of shame, inability to learn from experience, accidental motivation-driven behavior, and social maladjustment. However, these are relative.
The fifth edition of the Diagnostic and Statistical Manual of Mental Disorders lists six diagnostic criteria for antisocial personality disorder:
1. has the following personality defects, such as lack of compassion, self-centeredness, setting goals only for self-satisfaction, and being unable to establish intimate relationships with others.
2. Have the following morbid personality characteristics, such as being good at manipulating others, cheating, heartless, hostile to others, irresponsible, impulsive and adventurous.
3. These personality defects and characteristics must be long-term and stable.
4. These personality defects and characteristics are inevitably inconsistent with the individual's developmental age (many children are easily regarded as mental patients) and cultural environment.
Personal character and behavior are not caused by disease or substance abuse.
6. Individuals must be 18 years old-this standard is controversial, because many psychologists believe that patients will have symptoms in an emergency.
To sum up, if a person has three of the following seven characteristics, it is enough to be clinically diagnosed as "antisocial personality":
1. Unable to comply with social norms.
2. Used to cheating and manipulating others
3. Impulsive and unable to plan ahead
4. Irritability and influence on others
5. Have no scruples about the safety of yourself or others.
6. Always irresponsible
7. No regrets after hurting, abusing or stealing others.
How is antisocial personality formed?
We can influence the formation of a person's antisocial personality from three angles: heredity, family and culture.
Is antisocial personality innate or acquired? Consistent with most personality traits, the answer is probably both, in other words, a certain trait is possessed in the embryonic period.
In the family environment, anti-social personality children will refuse to establish a harmonious relationship with their families, and the family microenvironment affects the behavior of members in a complex and subtle way.
Finally, the influence of culture. Compared with eastern culture, western culture is more likely to produce tyrants. Because western culture emphasizes individualism, eastern culture emphasizes courtesy, justice, honesty and shame, and emphasizes monarch, minister and family to avoid ordinary people from doing excessive things.
In recent years, more and more attention has been paid to the genetic factors of antisocial personality disorder, and it has been found that personality disorder is related to the polymorphism or mutation of some genes. Early research found that 17%- 19% of relatives of schizophrenics were antisocial personality, but later research did not confirm it.
The change of human behavior is by no means caused by a single gene mutation. Paying attention to environmental factors, especially the family environment of individual's early growth and life, is particularly active for the prevention and treatment of antisocial personality disorder.
Anti-social personality people lack empathy, can't empathize with others, and sometimes they are even insensitive, but they don't necessarily have violent behavior, and some even have high IQ. Growing up in a warm and harmonious family can reduce the occurrence of personality disorders and crimes.
