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

Modern economic theory has experienced a persistent shift away from partial equilibrium modelling and towards the theory of general competitive equilibrium. Spatial economic analysis, however, has by and large remained rooted in the older approach.

Spatial Pricing, Spatial Rents, and Spatial Welfare
The Quarterly Journal of Economics, 1982This paper presents a model of spatial equilibrium that integrates elements of spatial pricing and ThA¼nen location models. Properties of equilibrium under mill, uniform, and discriminatory pricing regimes are explored. Three comparative propositions concerning firm, consumer, and landowner welfare that obtain under the alternative pricing schemes are ...

Spatial and spatial-frequency primitives in spatial-interval discrimination
Journal of the Optical Society of America A, 1985Thresholds for spatial-interval discrimination were determined under conditions designed to introduce randomness in the spatial-frequency content of the stimuli from trial to trial. Neither a random scaling of the display nor the addition of flanking bars at varying distances affected the observer's ability to judge the relative interval between pairs ...

Spatial Interaction and Spatial Autocorrelation
2008The objective is to combine insights from two research traditions, spatial interaction modelling and spatial autocorrelation modelling, to deal with the issue of spatial autocorrelation in spatial interaction data analysis. First, the problem is addressed from an exploratory perspective for which a generalisation of the Getis–Ord G statistic is ...

Spatial Flows and Spatial Patterns
Environment and Planning A: Economy and Space, 1984The misspecification of gravity spatial interaction models has recently been described by the author. The bias in parameter estimates that results from such misspecification appears to produce the ‘map pattern effect’ or ‘spatial structure bias’ in estimated distance-decay parameters.

Spatial Externalities, Spatial Multipliers, And Spatial Econometrics
International Regional Science Review, 2003This article outlines a taxonomy of spatial econometric model specifications that incorporate spatial externalities in various ways. The point of departure is a reduced form in which local or global spillovers are expressed as spatial multipliers. From this, a range of familiar and less familiar specifications is derived for the structural form of a ...

ACM SIGMOD Record, 2000
This paper discusses issues related to the integration of spatial operators into the new generation of SQL-like query languages. Starting from spatial data models, current spatial extensions of query languages are briefly reviewed and research directions are highlighted.

Twenty-one patients with right hemisphere damage were studied (11 men, 10 women; average age = 41.33; range = 19-65). Patients were divided in two groups: pre-Rolandic (six patients) and retro-Rolandic (15 patients) right hemisphere damage. A special reading test was given to each patient.
