Effects of report order, identification method, and stimulus characteristics on multidimensional stimulus identification

Abstract

An experiment was conducted to investigate the effect of order of report, identification method, redundant color coding, and stimulus location under dual task conditions on multidimensional stimulus-identification performance. Analysis showed that order of report and identification method did affect speed and accuracy of identification. Subjects reacted faster and more accurately if this order of reporting stimulus-dimension values was appropriate. Physical identification was also faster and more accurate than identification of meaning, but there was no effect for redundant color coding, stimulus location, and difficulty of the dual task on identification. The implications of the results for design of visual displays were discussed.
