Figure 1. Exemplar Pathfinder Stimulus Arrays.

Figure 1

Arrays of ten-by-ten randomly oriented Gabor elements (4 cycles per degree) were constructed with inter-element separation randomly jittered between 1 and 1.5 degrees of visual angle. In the case of contour-present arrangements, 10 of the Gabor elements were oriented within ± 30 degrees relative to the neighboring elements with no phase shift. An example is shown in the left hand panel where this arrangement of elements results in the perception of a snaking contour, which can be seen in the lower right corner of the panel. In the right hand panel, orientations of all elements are fully random and no countour is seen.
