A location task, in which a worker must locate a point in space given information on its position, has much in common with a Choice Reaction Time (CRT) task. One particular task, wiring of electronic components, was studied by measuring location time as a function of total information per stimulus. A linear relationship was found, confirming Hicks Law, but systematic deviations from the line were noted. Further analysis showed differential rates of information processing and suggested a two-stage strategy. The first stage corresponded to the usual binary classification in CRT studies, while the second had similarities to an exhaustive serial search.
