Summary

Brain pathways for mirror discrimination learning during literacy acquisition. Upper: The Visual Word Form Area [VWFA] (in red) presents mirror invariance before alphabetization and mirror discrimination for letters after alphabetization.

A key aspect of alphabetization is to set in place the audio-visual mapping known as “phoneme-grapheme correspondence,” whereby elementary sounds of language (i.e., phonemes) are linked to visual representations of them (i.e., graphemes) (Frith, 1986).

Lower: During alphabetization, the VWFA can receive top-down inputs with discriminative information from phonological, gestural (handwriting) and speech production areas and bottom-up inputs from lower level visual areas. All these inputs can help the VWFA to discriminate between mirror representations, thus correctly identifying letters to enable a fluent reading.
