The present studies were designed to assess the performance impact of symbologies composed of discrete elements relative to more conventional continuous symbologies. In an attempt to examine information processing of various components of behavior--such as information input, central processing and output--three different tasks were selected. A two-or-four alternative choice reaction time task demonstrated an ability to measure a difference between punctate and continuous information, and suggested that the difference is reduced with increased task complexity. A memory search task demonstrated the importance of symbology compatibility and a display search task revealed equal search efficiencies for punctate and continuous alphanumerics. Additional areas of investigation are discussed.
