Procedure

Healthy control:
We recruit 30 healthy control volunteers through a homepage and mailing-list from January 17, 2018. We obtain written informed consent using a document with the approval of the ethics committee. We conduct psychological test and EEG (N400) experiment in Kanazawa University hospital. We calculate earson correlation coefficient between N400 amplitude/latency and delusive thought score to show validation of this experiment.


Patients:
After showing validation of this experiment, we recruit 30 schizophrenia out/inpatient in Kanazawa University hospital diagnosed by physicians. We obtain written informed consent using a document with the approval of the ethics committee. We conducted EEG (N400) experiment by the same procedure of the healthy control group.
