Abstract Field of view (FOV) allows us to perceive and learn our environment. Reducing the visual field impairs our ability to estimate distance and direction. It has been demonstrated that distance is estimated more accurately in outdoor environment (a lawn) than in indoors (hallway or lobby). This evidence suggests that features like width of environment, that is the openness of the environment that extends into periphery, might be important in affecting spatial representation. We studied route learning in Venice where features may or may not restrict the width of environment. Seventy participants learned narrow and wide routes from videos, then performed various spatial recall tasks. Results showed that environmental features that restricted the width of environment impaired participants’ pointing performance, and the metric properties of their mental representations. This study newly shows that environmental features naturally restricting the width of environment can influence the ability to form spatial mental representations.
