The results demonstrated that regardless of whether the scene was rotated or the observer moved, greater angular disparity between judged and encoded views produced slower RTs.Thus, in contrast to previous findings which did not consider a wide range of observer movement, our data show that observer movement does not necessarily automatically update representations of spatial layouts in small-scale (room-sized) environments and raise questions about the effects of duration limitations and encoding points of view on the automatic spatial updating of representations of scenes.This chapter discusses the basic properties of spatial representations for navigation, spatial reasoning, and object/scene recognition.Contrary to the traditional models of allocentric cognitive maps, recent findings suggest that spatial representations for navigation, real world object and scene recognition, and spatial reasoning are primarily egocentric, and these egocentric representations are updated as the viewer moves.Spatial updating is a very common process found in almost all species tested, including insects, birds, rodents, and primates including humans. Spatial updating of virtual displays during self- and display rotation. Precision of spatial updating varies across species and individuals, and errors can accumulate over time.
Across two experiments we investigated spatial updating in environments encoded through narratives. At the neuronal level, spatial updating is thought to be maintained by receptive field locations that shift with changes in gaze, and evidence for such shifts has been shown in several cortical areas.These regions receive information about the intervening movement from several sources including motor efference copies when a voluntary movement is made and vestibular/somatosensory signals when the body is in motion.Spatial updating refers to the cognitive process that computes the spatial relationship between an animal and its surrounding environment as it moves based on perceptual information about its own movements.
