Schizotaxia, schizotypy, and liability to schizophrenia

The schizotypal personality traits broadly correspond to the positive, negative and disorganized dimensions observed in schizophrenia. The personality traits include positive (cognitive-perceptual), such as magical thinking, unusual perceptual experiences, ideas of reference and paranoia; disorganization, such as odd behavior and odd speech; and negative (interpersonal), such as constricted affect, social anxiety, lack of close personal relationships, and suspiciousness. Disorganization includes odd behaviour and odd speech.³
