New research on individuals with schizotypal personalities - people characterized by odd behavior and language but who are not psychotic or schizophrenic - offers the first neurological evidence that they are more creative than either normal or fully schizophrenic individuals, and rely more heavily on the right sides of their brains than the general population to access their creativity.
Vincent Van Gogh, Albert Einstein, Emily Dickinson and Isaac Newton are amongst the few who can be cited as an example in this regard.
AdvertisementTwo experiments were conducted to compare the creative thinking processes of schizotypes, schizophrenics and normal control subjects. In the first experiment, the researchers showed research subjects a variety of household objects and asked them to make up new functions for them. The results showed that the schizotypes were better able to creatively suggest new uses for the objects, while the schizophrenics and average subjects performed similarly to one another.
In the second experiment, the three groups again were asked to identify new uses for everyday objects as well as to perform a basic control task while the activity in their prefrontal lobes was monitored using a brain scanning techniques called near-infrared optical spectroscopy. The brain scans showed that all groups used both brain hemispheres for creative tasks, but that the activation of the right hemispheres of the schizotypes was dramatically greater than that of the schizophrenic and average subjects, suggesting a positive benefit of schizotypy.
The researchers believe that the results offer support for the idea that schizotypes and other psychoses-prone populations draw on the left and right sides of their brains differently than the average population, and that this bilateral use of the brain for a variety of tasks may be related to their enhanced creativity.
