Collinearity, curvature interpolation, and the power of perceptual integration

Nikolaev, Andrey R. LU orcid and Leeuwen, Cees Van (2007) In Psychological Research 71(4). p.427-437
Abstract

In three experiments, participants determined the orientation of a global triangle formed by three Gabor patches of a target spatial frequency in a field of distracters. The orientation of the target patches and their proximity were varied between conditions. When all the target patches had the same orientation this facilitated the response compared to random orientations. This effect occurred only when the patches were in close proximity. When the orientations of the target patches were different but aligned to the global triangle, facilitation occurred regardless of proximity. These contrasting types of facilitation were attributed to different early perceptual integration mechanisms that enable the perception of holistic... (More)
