Is it a pathological phenomenon when we can't control ourselves and feel like a suddenly changed person?
Schizophrenia vs split personality
Schizophrenia is a mental illness, and its symptoms are delusions and hallucinations. Some patients will have symptoms of numbness or excitement.
John Forbes Nash, a mathematician in the Oscar-winning film A Beautiful Mind, is a typical schizophrenic.
More than half of schizophrenics are diagnosed as paranoid schizophrenia.
Schizophrenia and schizophrenia patients are accompanied by delusions.
The difference between the two lies in the delusion that the voice heard in the mind of schizophrenic patients is the voice of the outside world, which means that schizophrenic patients can't tell the truth from fiction.
The delusion of schizophrenics is to hear voices in their own heads, but different people are talking.
It should be noted that schizophrenia is currently regarded as a disease dominated by heredity and supplemented by environment.
In terms of incidence, the incidence of schizophrenia is about 0.5%- 1%, while the personality classification is about one in a thousand. The incidence of schizophrenia is much higher than that of split personality.
The psychological term for split personality is called dissociative identity disorder.
The more popular name is "multiple personality disorder" or "dissociative personality disorder".
Symptoms describe that patients have multiple personalities, and these personalities cannot perceive each other.
There are two main puzzles about split personality:
Each of us will split ourselves sometimes. Is this a split personality?
How should doctors choose and decide what kind of personality they should leave in the face of patients with split personality?
Generally speaking, split personality is often the result of childhood trauma.
We divide the different personalities of schizophrenics into core personality and non-core personality.
Core personality refers to the initial personality, and the reason why patients have personality disorders is often because the pathological characteristics of core personality are too strong.
The nightshade in Legend of the Sword and the Chivalrous Man 3 is a kind of split personality. For example, before Solanum nigrum was bullied, her core personality was weak and unable to cope with the oppression of external monsters for a long time, so Hong Kui, a non-core personality, appeared to help her.
Another difference between core personality and non-core personality is that non-core personality knows the existence of core personality, while core personality doesn't know the existence of non-core personality.
Just like the blue sunflower doesn't know the red sunflower, but the red sunflower knows the existence of the blue sunflower.
Psychologists often choose to cure the pathological characteristics of the core personality and leave the core personality when facing the choice of patients with split personality.
Personality split and split
Personality split is the result of self-dissociation, but each of us will use dissociation as a psychological defense.
In other words, whether there will be a split personality depends on the intensity of dissociation.
Dissociation and isolation are both ways of psychological defense, but unlike dissociation, isolation means that we retain the ability to think and recognize events and remove the emotional cognition of events.
For example, a wife calmly states her husband's affair. She knew about her husband's extramarital affairs, but she eliminated her feelings.
We can think that division is the means by which we choose to disintegrate ourselves. Why do you want to disintegrate yourself?
The first reason is that we can't bear the impact of events on us at all, and the second reason is that we are ashamed of our existence, which is why the dissociation defense mechanism occurs.
Everyone will feel great pain and shame in life. At these moments, the defense mechanism of dissociation will appear. The essential reason for its disintegration is to offset these unpleasant feelings.
Because if the ego collapses, it won't be me who experiences those unpleasant things.
It can be said that isolation means that a person stands by and looks at what happens to him from a distance, while alienation means that a person stands by and looks at his own affairs, just like looking at other people's affairs.
Only by dissociation can we not develop into schizophrenics, because after rehabilitation, we feel that we are a complete individual again.
Divide me or unify me
A question discussed in philosophy is "Does human beings have soul and consciousness?" The existence of soul and consciousness means that we have a unified self, but the opposite view holds that the self owned by human beings is the divided self.
The reason why we feel different from ourselves in life is that there is a unified me in the world.
But in life, we all have different opinions on such a trivial matter as whether to eat a cone or not, which is enough to show that what human beings have is to share me.
Psychiatrist Sullivan described personality like this:
"Personality is a relatively lasting pattern of repetitive interpersonal situations, and repetitive interpersonal situations are the characteristics of a person's life ... there are as many kinds of personality as there are typical interpersonal relationships".
Sometimes I feel that life is divided, not necessarily schizophrenia.
First of all, we are conscious, which does not conform to the symptoms of schizophrenia; Secondly, although each of us has stable self-characteristics, we will change occasionally.
