Personality is the combination of thoughts, emotions and behaviors that makes you unique. It's the way you view, understand and relate to the outside world, as well as how you see yourself. Personality forms during childhood, shaped through an interaction of inherited tendencies and environmental factors.

In normal development, children learn over time to accurately interpret social cues and respond appropriately. For people with schizotypal personalities, something goes wrong during this process, leading to illogical beliefs, unusual thinking and paranoid feelings. What exactly goes wrong isn't known, but it's likely that one or more factors cause problems with the way the brain functions, and genetics may play a role.
