Are deluded people unusually prone to illusory correlation?

This study reexamines the possibility that paranoid individuals are unusual ly prone to perceive; illusory correlations. The authors use emotionally ne utral word pairs to examine the illusory correlation phenomenon in three di agnostic groups: nonparanoid schizophrenia (n = 10), paranoid schizophrenia or delusional disorder(n = 9),and (n = 10). A one-way analysis of variance shows that the three groups do not differ in their tendency to make illuso ry correlations. Three separate t tests that compare the data from each of the clinical groups in this study with normative data again reveal no signi ficant difference. The clinical implications of these findings are discusse d.
