Left-right confusion and the perception of bilateral symmetry.
The present study investigates the relationship between the perception of bilateral symmetry and left-right disorientation in neurologically-intact adults. Using tachistoscopic presentation of stimuli and a choice reaction-time procedure, we found a small but consistent trend toward quicker symmetry judgements in left-right confused subjects. Possible neuropsychological mechanisms underlying this curious finding are discussed.
