Abstract : A study was accomplished to demonstrate the influence of display coding on a task of locating and identifying specific entries in a numerical matrix. Various relationships among factors of matrix size, complexity, and viewing time were determined and are presented in graphic form. In addition to demonstrating the expected efficacy of coding, several additional findings were revealed. It was found that coding is of particular value when search time is limited, and that as the difficulty of the task increases the value of coding also increases. It was also shown that with longer search times available, the relative value of coding appeared to increase. This finding was interpreted as the result of a two-stage data extra-ction effort: the first stage being a locating of the pertinent data entries, the second stage being the actual reading of the displayed values.
