Abstract
The study investigated the effectiveness of redundant color-codes and monochrome shape-codes for coding the operational states of scanpoints displayed on a CRT-displayed process-control diagram. Response-times were faster with color-coding than with shape-coding, and this relationship generally held true across all levels of display density and inspection load, with both search and identification tasks. Also, color-coding mitigated the detrimental effects of increased density and load. Coding did not affect response-accuracy on the search task, but on the identification task more errors were produced with shape-coding.
