The current research project aimed to investigate how various degrees of psychosis and autism traits were associated with different styles of reasoning. Therefore, a series of five studies were conducted that recruited participants who were considered to reside along different points of the psychosis and autism continua. Measures of intuitive and deliberative reasoning style were employed and were used to ascertain whether differing degrees of psychosis and autism reflected different profiles of reasoning style. In addition, a composite score was devised using the raw scores of measures of psychosis and autism traits to test Crespi and Badcocks (2008) diametric disorders hypothesis and to further explore the relationship between the two measures. Overall, the results revealed some evidence that psychosis traits were associated with a more intuitive relative to deliberative style of reasoning, whereas autism traits were reflective of the reverse profile. The findings were also able to shed further light on the intricate relationship between autism and psychotic spectrum disorders.
