Relationship between perceptual stability and reversal of perspective

We have examined the relationship between the perspective reversal of both the Necker cube and the Schröder staircase and perceptual stability for 49 undergraduate students in psychology. There was a positive, statistically significant correlation of moderate magnitude between number of reversals of the Necker cube and differential score of perceptual stability, i.e., the difference between persistence of the visual image under right and left monocular viewing.
