While normal people’s thinking is subjectively controlled by themselves, some patients with schizophrenia feel that their thinking is not under their control, or experience that their thinking no longer belongs to them, but is controlled by an external force. This means that the patient feels that their thinking does not belong to them, that their thinking activity has lost its autonomy, or that it is controlled by an external force. Examples of such experiences are thought deprivation, thought insertion, and thought diffusion. Thought insertion, thought deprivation, and thought diffusion are common in the early stages of schizophrenia and in the full development of symptoms. Methods of examination for abnormal thought control 1. Some patients feel that there is thinking in their head that does not belong to them and has been imposed on them by others, and therefore feel that this thinking is not at their disposal and control, which is called thought insertion. 2. Some schizophrenia patients feel that their thinking is suddenly taken away by an external force, which is called thinking being taken away. 3. Other schizophrenic patients feel that their thinking is broadcast out for the well-known, which is called thinking broadcast, also called thinking being broadcast.
