Spatial multistability and nonvariational effects

Physical Review E, 1999
We investigate the phenomenon of spatial multistability of fronts in thin bistable systems and stress the important role played by the absence of a variational principle. Nonvariational effects allow, for instance, two different immobilized fronts to coexist.

Sequential effects modulate spatial biases.

Journal of Experimental Psychology: General, 2017
Healthy individuals usually display a bias toward the left side of space. This effect can be measured in a line bisection task or, alternatively, in a landmark task where prebisected lines are presented to participants. Several factors have been shown to influence pseudoneglect, that is, to vary the magnitude of the left side bias.

Spatial Effects on Temporal Categorisation

Perception, 2009
We examined the influence of spatial factors in temporal processing. Participants categorised as short or long empty intervals marked by two brief flashes delivered from locations differing in height and depth (experiment 1), or from two of three locations on a vertical plane (experiment 2).

Spatial Content and Spatial Quantisation Effects in Face Recognition

Perception, 1994
It has recently become apparent that if face images are degraded by spatial quantisation, or block averaging, there is a nonlinear acceleration of the decline in accuracy of recognition as block size increases. This suggests recognition requires a critical minimum range of object spatial frequencies.

Virtual collaboration: effect of spatial configuration on spatial statements production

Cognitive Processing, 2015
When guiding a remote collaborator in a virtual environment, people often take an addressee-perspective, which may have a high cognitive cost. In order to improve collaborative virtual environments, a better understanding of how operators share spatial information is needed.

Spatial dispersion effects in polariton solitons

Physical Review B, 1992
Effects of the exciton dispersion on the properties of polariton solitons in gyrotropic and nongyrotropic crystals are investigated. Bell- and kink-type solutions are obtained, and the conditions for their existence are determined. For excitons with a positive effective mass, a change of the type of the solution is shown to take place at a critical ...

Spatial effects in social dilemmas

Journal of Theoretical Biology, 2006
Social dilemmas and the evolutionary conundrum of cooperation are traditionally studied through various kinds of game theoretical models such as the prisoner's dilemma, public goods games, snowdrift games or by-product mutualism. All of them exemplify situations which are characterized by different degrees of conflicting interests between the ...

SPATIAL EFFECTS IN TACTILE METACONTRAST MASKING

Perceptual and Motor Skills, 1973
Summary.-Masking of and by mechanical tactile stimuli was investigated as a function of spatial relations between the stimuli. Masking was stronger when the stimuli were applied to the same side of the body than when they were placed contralaterally to each other.
