The development of wayfinding competency: Asymmetrical effects of visuo-spatial and verbal ability

A cognitive developmental study examined the effects of visuo-spatial abili ty (V-SA) and verbal ability (VA) on wayfinding performance in young and ol der children. The age groups used corresponded to the pre-operational and c oncrete operational Piagetian stages of cognitive development. In addition to completing a battery of tests measuring V-SA and VA, children undertook a wayfinding task in a forward and reverse direction. High V-SA children ex hibited superior wayfinding skills to low V-SA children. In contrast, VA fa iled to influence wayfinding performance. Further analysis revealed that th e effects of V-SA were only reliable in young children, suggesting that old er children develop additional representational abilities that are neither visuo-spatial nor verbal in nature. Applications of these findings are disc ussed in terms of their implications for environmental design and planning. (C) 2000 Academic Press.
