Resumo(s)
Discrimination of reversible mirrored letters (e.g., d and b) poses a challenge
when learning to read as it requires overcoming mirror invariance, an evolutionaryold perceptual tendency of processing mirror images as equivalent. The present study
investigated when, in reading development, mirror-image discrimination becomes
automatic during visual word recognition. The developmental trajectory of masked
priming effects was investigated from 2nd to 6th grade and in adults, by manipulating
letter type (nonreversible; reversible) and prime condition (control; identity; mirrored;
rotated). Standardized identity priming increased along reading development. Beginning readers showed mirror invariance during reversible and nonreversible letter
processing. A mirror cost (slower word recognition in mirrored-letter than identity
prime condition) was found by 5th-grade but only for reversible letters. By 6th grade,
orthographic processing was no longer captive of mirror invariance. A multiple linear
regression showed that letter representations, but not phonological processes or age,
were a reliable predictor of the rise of mirror-image discrimination in 2nd–4th-graders.
The present results suggest a protracted development of automatic mirror-image discrimination during orthographic processing, contingent upon the quality of abstract
letter representations.
