SUMMARY:

A defining characteristic of humanity as a species is its ability to invent and culturally transmit technologies that were responsible for transforming life on Earth. One of these greatest inventions that allowed humans to “communicate their thoughts” throw visual support is writing and reading. One visual difficulty that children face is mirror writing by creating confusion between mirror letters (e.g., b=d). Mirror confusion for letters emerges as a natural consequence of a deeply rooted visual mechanism in our visual system: the mirror invariance. Mirror invariance is a visual mechanism that enables a prompt recognition of mirror images. This visual capacity emerges early in human development and is useful to recognize objects, faces, and places from both left and right perspectives, and is also present in primates, pigeons, and cephalopods. Thus, mirror discrimination for letters should be learned for fast letter recognition and thus for fluent reading. But traditionally, schools do not provide such specific learning and the correct orientation of letters is learned sparsely, with time. Based on that we applied a specific targeted training to address mirror confusion for letters in 1st graders learning to read. The training was based on our hypothetical mechanism: “multisystem mappings”, i.e., mappings of letter representation across sensory-motor systems. To keep the training short (7.5 hours in total, across 3 weeks), we associated a physiological learning enhancer: post-training sleep consolidation. We observed massif effects of mirror discrimination learning for letters and a critical role played by sleep consolidation in the magnitude, automaticity, and long-term duration of this specific learning.
