Is there a bias in size measurements taken from mirror-reversed photographs of body parts?
This study compared measurements of hands, feet, and hemifaces taken from original and mirror-reversed photographs to determine whether a hemispace-bias exists in size measurements. Posers were adult right- and left-handers (50% female). In 80% of the measurement comparisons (total N = 84), there was complete agreement; there were no instances of right-left reversals among the discrepant comparisons. The side of the body measured as larger was independent of the side of space in which it appeared. The lack of such bias in physical measurements is discrepant with data suggesting a left-hemispace preference in psychological judgments of visual material.
