Spatial Representations Without Spatial Computations
Psychological Science, 2022Cognitive maps are assumed to be fundamentally spatial and grounded only in perceptual processes, as supported by the discovery of functionally dedicated cell types in the human brain, which tile the environment in a maplike fashion. Challenging this view, we demonstrate that spatial representations—such as large-scale geographical maps—can be as well ...

Spatial Representation of Maps
The American Journal of Psychology, 1983Two experiments tested the hypothesis that the cognitive representation of spatial relations on a map is primarily a visually keyed process. In Experiment 1, undergraduates studied a labeled map where features were presented either as words alone, as mimetic drawings of the referent, or as geometric symbols.

SPATIAL KNOWLEDGE REPRESENTATION
International Journal of Pattern Recognition and Artificial Intelligence, 1989The use of spatial knowledge is necessary in a variety of artificial intelligence and expert systems applications. The need is not only in tasks with spatial goals such as image interpretation and robot motion, but also in tasks not involving spatial goals, e.g. diagnosis and language understanding.

Prelexical Spatial Representations
Cognitive Neuropsychology, 1996The Simon task was employed to establish the nature of the representation of printed words with which the mental lexicon is accessed. In the first five experiments, the subjects were required to discriminate target letters in words or nonwords, presented vertically or horizontally.

The Role of Vision in Spatial Representation
Cortex, 2004A complex link exists between vision and unilateral spatial neglect (USN). Firstly, USN is not a perceptual deficit, secondly, USN is not necessarily accompanied by a visual deficit and finally, USN can be observed in non-visual modalities as well as in mental spatial imagery. This apparent supramodality of USN stands in sharp contrast to the fact that

On Linked Spatial Representations
Journal of Knot Theory and Its Ramifications, 2001What is the smallest positive integer m=m(L) such that every linear spatial representation of the complete graph with n vertices, n≥m contain cycles isotopic to link L? In this paper, we show that [Formula: see text]. The proof uses the well-known cyclic polytope and its combinatorial description in terms of oriented matroids.

A unified representation of spatial displacements
Mechanism and Machine Theory, 1984Abstract The spatial screw displacement of a rigid body can be expressed in terms of points and in terms of lines by real (3 × 3)-matrices and (4 × 4)-matrices for the screw displacement of points, and by dual vectors and tensors, dual-number (3 × 3)-matrices, screw coordinates and dual-number quaternions for the screw displacement of lines.

The Effect of Barriers on Spatial Representations
Child Development, 198148 first graders and 48 fifth graders learned the arrangement of 6 objects in a novel environment containing 2 large barriers. 3 nonoverlapping paths, each connecting all locations, were devised. Children were assigned to 4 experimental conditions representing the factorial combination of number of trials of walking (2 vs.
