Despite strong interest in understanding how habitat spatial structure shapes the genetics of populations, the relative importance of habitat amount and configuration for patterns of genetic differentiation remains largely unexplored in empirical systems. In this study, we evaluate the relative influence of, and interactions among, the amount of habitat and aspects of its spatial configuration ...

The algorithmic design of an architectural configuration depends on one's ability to compare the merit of different solutions quantitatively, in order to decide which design is superior. We propose a merit function that accounts for the amount of view from a given unit and its accessibility to other units. The amount of view is measured as the size of the spatial region visible from the center ...

The concept of spatial ...

In order to collaborate with people in the real world, cognitive systems must be able to represent and reason about spatial regions in human environments. Consider the command “go to the front of the classroom”. The spatial region mentioned (the front of the classroom) is not perceivable using geometry alone. Instead it is defined by its functional use, implied by nearby objects and their confi...

Some individuals automatically and involuntarily “see” mental images of numbers in spatial arrays when they think of numbers (number forms). Makioka (2009) proposed a theoretical framework called self-organizing learning account of number forms (SOLA), which argues that number forms are generated by self-organizing learning between numerical and spatial representation. This framework explains t...

Representations of target features (attentional templates) guide attentional object selection during visual search. In many search tasks, targets objects are defined not by a single feature but by the spatial configuration of their component shapes. We used electrophysiological markers of attentional selection processes to determine whether the guidance of shape configuration search is entirely...
