A shape-level flanker facilitation effect in contour integration and the role of shape complexity

The detection of an object in the visual field requires the visual system to integrate a variety of local features into a single object. How these local processes and their global integration is influenced by the presence of other shapes in the visual field is poorly understood. The detectability (contour integration) of a central target object in the form of a two dimensional Gaborized contour was compared in the presence or absence of nearby...
