Conflicting predictions from Broen's and Chapman's theories of schizophrenic thought disorder
AbstractDeveloped multiple-choice vocabulary items containing a correct alternative which was the dominant (most frequent) response for normal ss, an associative distractor alternative of nearly equal frequency, and an irrelevant alternative. W. Broen and L. Storms's theory predicts that a response which is nondominant for normals can never become dominant for schizophrenics, while L. Chapman's theory predicts that such a response can do so if it expresses a normal response bias. 26 chronic schizophrenics chose significantly more associative than correct responses on items for which 26 normals (matched on sex, age, education, and social position) chose significantly more correct than associative. Results are consistent with chapman's theory.
