Psychological disorders have etiologies that are largely multi-factorial, involving complex interactions between genetic and environmental factors. Early environmental exposures influence schizophrenia expression even in the presence of strong genetic predisposition. E., Cannon, M., Mc Clay, J., Murray, R., Harrington, H., Taylor, A., Arseneault, L., Williams, B., Braithwaite, A., Poulton, R., Craig, I. A number of risk factors have been implicated in the development of psychological disorders, but their relative contributions to mental illness are specific to different disorders and individual patients, and a precise cause can rarely be identified on an individual basis.(1) Below is a sampling of some of the variables identified as risk factors in the development of psychological disorders. Although the topic is primarily focused on psychology, psychiatry, and neuroscience, we will consider submissions from other disciplines if relevant to the topic area.
Mental imagery is increasingly shown in the literature to play a key role in various psychological disorders.
The exploration of mental imagery represents a new and important area within clinical psychology, but arguably one still in its infancy.

Twin studies report the concordance rate of schizophrenia (the probability that one twin will have the disorder if the other twin does) to be 45 to 60 % for monozygotic (identical) twins, compared to only 10 to 15 % for dizygotic (fraternal) twins.
