New paper in Memory & Cognition: Late sign language exposure does not modulate the relation between spatial language and spatial memory in deaf children and adults by Dilay Karadöller, Beyza Sümer, Ercenur Ünal & Aslı Özyürek
Prior work with hearing children acquiring a spoken language as their first language shows that spatial language and cognition are related systems and spatial language use predicts spatial memory. In this paper, authors further investigate the extent of this relationship in signing deaf children and adults and ask if late sign language exposure modulate subsequent memory for spatial relations.
To assess whether late sign language exposure, as well as the frequency and the type of spatial language use that might be affected by late exposure, modulates memory for spatial relations, Dilay Karadöller, Beyza Sümer, Ercenur Ünal & Aslı Özyürek compared spatial language and memory of 8-year-old late-signing children and late-signing adults to their native-signing counterparts. Authors elicited picture descriptions of Left-Right relations in Turkish Sign Language (Türk İşaret Dili) and measured the subsequent recognition memory accuracy of the described pictures. Results showed that late-signing adults and children were similar to their native-signing counterparts in how often they encoded the spatial relation. However, late-signing adults but not children differed from their native-signing counterparts in the type of spatial language they used. However, neither late sign language exposure nor the frequency and type of spatial language use modulated spatial memory accuracy. Therefore, authors conclude that even though late language exposure seems to influence the type of spatial language use, this does not predict subsequent memory for spatial relations. Authors discuss the implications of these findings based on the theories concerning the correspondence between spatial language and cognition as related or rather independent systems.
