The central dilemma, addressed by Claridge at the outset, is that “schizotypy” is a rather specific term that is unambiguously associated with schizophrenia in its current usage. The terms used by Claridge and the chapter authors, however, appear to be more related to psychoticism. The choice of schizotypy fits well with some of the research literature that is presented, but the multidimensional approach espoused by the authors suggests that schizotypy consists of a number of dimensions, including psychoticism, negative schizotypy (marked by social withdrawal), and cognitive disorganization. Psychotic-like phenomena are the least specific aspect of schizotypy because they can extend from schizophrenia and bipolar disorder to other psychotic disorders, dyslexia, drug-induced states, and different forms of delirium. Yet, it is the rather quieter and sometimes more subtle social deficit symptoms that seem particularly specifically related to schizophrenia. At a time of intense interest in investigating the prodrome and endophenotypes related to schizophrenia, it is helpful to be reminded of this distinction. For example, Richardson reminds us in her chapter on dyslexia in schizotypy that psychotic-like symptoms can be common in dyslexia with no predictive power for a diagnosis of schizophrenia.
