Nonverbal Rigidity and Its Relationship to Performance on Three Standard Reversible Figures

Summary

This study investigated the relationship between nonverbal rigidity, as measured by the Breskin Rigidity Test (BRT), and performance on three standard reversible figures: the Necker Cube, the Rubin Vase, and the Mach Book. No significant relationships between the BRT and frequency of reported reversals for any of the three figures were found. These results were taken to indicate that the BRT does not measure “perceptual rigidity,” but may measure what has been called obsessive-compulsive rigidity.
