- Original description
Disturbances in the sense of self and time could play an important role in the development of psychotic symptoms. Previous work has shown that patients have difficulty preparing to process information on the scale of a second, but are abnormally disturbed by slightly asynchronous information on the millisecond scale. In both cases, the anomalies could explain the patients' unusual experience of time. The hypothesis in neurotypical patients is that small delays or asynchronies asynchronies are treated as irrelevant information and ignored and ignored, whereas in patients suffering from schizophrenia they would disrupt the flow of time. This hypothesis is tested with a new visual illusion.Read full original descriptionShow less
