Redundancy in Coding of a Visual Display as Assessed by a Signal Detection Paradigm

A signal detection paradigm was applied to performance of a visual search task under varying degrees of shape-color redundant coding and two levels of practice. The coding conditions were (1) Black and White, (2) Totally Nonredundant, (3) Partially Redundant, and (4) Totally Redundant. In addition to the traditional signal detection measures, subjective coding condition preference ratings were also recorded. Generally, the objective performance measures were influenced by practice. However, neither the objective nor the subjective measures were affected by coding conditions. A significant Coding Condition by Practice interaction on the percentage of correct responses was also found.
