Figure 5.

Figure 5.

A vernier was flanked by either 1 or 6 lines on each side having either the same length or a length twice as long as the vernier. With the single flanks (# flanks 2), B-type masking occurs for both lengths. With 6 flanking lines on each side, strong A-type masking occurs for equal length flanks and an almost flat masking function for the double length flanks with thresholds only slightly above the one for an unmasked vernier. This figure summarizes results which cover four figures in Duangudom, Francis, & Herzog (2007). Stimulus examples sketch the condition for an SOA of 0 ms, i.e. simultaneous presentation. The vernier target is always the center element.
