Reading mirror-reversed text: sinistrals really are inferior.
R. Tankle and K. M. Heilman (1982, Brain and Language, 17, 124-132) reported a sinistral superiority in obligatory reading of left-right mirror-reversed material. Their subjects included weak left- and right-handers. J. L. Bradshaw, N. C. Nettleton, L. Wilson, and V. Burden (1985, Brain and Language, 26, 322-331) employed a variety of geometrically transformed text, including mirror-reversed, and found that strong familial sinistrals were either not different from or were even slightly inferior to dextrals in reading most transformations, including left-right mirror reversals. We now report a study using subjects selected according to criteria similar to those of Tankle and Heilman, and find under these conditions that sinistrals are indeed significantly inferior to dextrals.
