Isi artikel

Schizophrenia is the most devastating form of psychopathology known to humankind, and it has been slow to yield clues to its origins. Meehl’s (1962, 1990) model detailed the nature of the latent liability for schizophrenia known as schizotypy and provided a major organizing function for research on schizophrenia. The schizotypy model integrates genetic and environmental contributions to liability as well as accounting for a range of clinical outcomes, all deriving from a genuine liability for the illness. Schizotypy, as a latent personality organization that harbors the liability for schizophrenia, provides a framework for detecting fundamental features of liability to schizophrenia prior to the onset of clinical illness. The schizotypy model is reviewed, the strategic benefits of it are discussed, and methods for detecting schizotypy are presented. A focus on perceptual aberrations—a schizotypic feature—in individuals unaffected by schizophrenia has yielded valuable clues to preclinical disturbances in neurocognitive processes, risk for schizophrenia among biological relatives, and genomic substrates, all of which are of interest to schizophrenia researchers.
