Repetition suppression for mirror images of objects and not Braille letters in the ventral visual stream of congenitally blind individuals
Mirror-invariance is the cognitive tendency to perceive mirror-image objects as identical. Mirrored letters, however, are distinct orthographic units, and must be identified as different; mirror-invariance must be ‘broken’ to enable efficient reading. Consistent with this phenomenon, a small, localized region in the ventral visual stream, the Visual Word Form Area (VWFA), exhibits repetition suppression to both identical and mirror pairs of objects but only to identical, not mirror, pairs o…
