 Far-Apart Values on Spatial Dimensions

Show Summary Details


The results from summation experiments using far-apart values can be summarized as answers to two questions: (a) Do multiple analyzers exist along the dimension? (b) If so, is there probability summation among the analyzers? For spatial frequency the answer to both questions is yes. This chapter presents the other spatial dimensions: orientation, spatial position (in two dimensions), spatial extent (in two dimensions), and spatial phase. It also discusses the questions of interdependence among dimensions and how they affect results, e.g., the interdependence of spatial position with spatial frequency, orientation, and spatial extent.

Keywords: summation experiments; spatial frequency; orientation; spatial position; spatial extent; spatial phase; probability summation
