Figure 5.

An example of how shine-through depends on the temporal layout of the grating is shown. The results are determined in terms of thresholds (i.e., the spatial offset of the preceding vernier for which 75% correct responses are reached). (A) Elements in the center of the grating were displayed earlier (as in this example) or later than outer elements. Actual gratings comprise 23 elements. (B) Even if the outer 2 × 9 double-bars are presented only 10 ms later than the central five elements, a significant deterioration of performance is found. Depending on temporal onset difference, shine-through can be completely eliminated. Negative onset differences mean the outer elements appear before the central five elements; positive onset differences mean the outer elements appear after the central five elements. Simultaneous presentation occurs for zero onset difference.
