Beyond Core Knowledge: Natural Geometry
Euclidean geometry may be founded on at least two distinct, evolutionarily ancient, core cognitive systems for representing the shapes of large scale, navigable surface layouts and of small-scale, movable forms and objects. Expand

Children's use of geometry for reorientation.
Research on navigation has shown that humans and laboratory animals recover their sense of orientation primarily by detecting geometric properties of large-scale surface layouts (e.g. room shape),Expand

Reorientation and Landmark-Guided Search by Young Children
Disoriented 4-year-old children use a distinctive container to locate a hidden object, but do they reorient by this information? We addressed this question by testing children's search for objects inExpand

Two systems of spatial representation underlying navigation
We review evidence for two distinct cognitive processes by which humans and animals represent the navigable environment. One process uses the shape of the extended 3D surface layout to specify theExpand

Navigation as a source of geometric knowledge: Young children’s use of length, angle, distance, and direction in a reorientation task
Geometry is one of the highest achievements of our species, but its foundations are obscure. Consistent with longstanding suggestions that geometrical knowledge is rooted in processes guidingExpand

Direct Electrical Stimulation of the Human Entorhinal Region and Hippocampus Impairs Memory
Deep brain stimulation (DBS) has shown promise for treating a range of brain disorders and neurological conditions. One recent study showed that DBS in the entorhinal region improved the accuracy ofExpand

Young children reorient by computing layout geometry, not by matching images of the environment
Disoriented animals from ants to humans reorient in accord with the shape of the surrounding surface layout: a behavioral pattern long taken as evidence for sensitivity to layout geometry. RecentExpand

A modular geometric mechanism for reorientation in children
Although disoriented young children reorient themselves in relation to the shape of the surrounding surface layout, cognitive accounts of this ability vary. The present paper tests three theories ofExpand

Research on humans from birth to maturity converges with research on diverse animals to reveal foundational cognitive systems in human and animal minds. The present article focuses on two suchExpand

Chicks, like children, spontaneously reorient by three-dimensional environmental geometry, not by image matching
Spatial reorientation by layout geometry occurs in numerous species, but its underlying mechanisms are debated. While some argue that navigating animals' sense of place is based on geometricExpand
