Data obtained from the Personal Beliefs Scale of Embree and Embree wer
e used to develop an analysis of variance model for mind-body belief w
hich emphasized a distinction between ''conventional'' and ''unconvent
ional'' mind-body beliefs. By means of this model a critically importa
nt distinction between high scoring second-order psychosomaticism subj
ects was achieved. It was proposed that subjects low in unconventional
/high conventional tend to employ classical logic when rating mind-bod
y belief items and that subjects high in unconventional/high conventio
nal mind-body belief characteristically engage in fuzzy logic. Possibl
e applications of the model in research were discussed.
