This study compares the performance of blind and sighted children (6-11 years old) in the production and comprehension of spatial prepositions and motion verbs in French language. In both populations, performance was better in comprehension than in production and with prepositions than with verbs. Performance was better in the sighted than in the blind, although with prepositions this difference mostly concerned young children and gradually disappeared thereafter. With verbs, population differences decreased only at 11 years and never disappeared entirely. In both populations, but especially among blind children, performance was better with prepositions marking containment or implying a vertical plane than with those implying a sagittal plane, particularly with non-oriented entities. Performance was also best when verbs implied a vertical plane (ascend, descend). The discussion explores implications of these results in light of blind children’s performance.
