Study Summary

Atypical developpement of spatial cognition has been shown in congenital bindness with some consequences on mathematic learning (Cattaneo et al., 2010) as well as on the mental representation of spatial maps (Thinus-Blanc & Gaunet, 1997). This raises the issue of the role of vision in spatial abilities underlying mathematics and locomotion. These difficulties could also be found in case of partial visual deficiency, like very low visual acuity or large peripheral shrinkage of the visual field.
