The Influence of Simultaneous and Sequential Display Modes on Human Information-Transfer Behavior

Abstract

The experiment investigated how two display modes affect human information-transfer performance. Subjects read test numbers from a cathode-ray tube and entered them into a keyboard. The numbers appeared either one digit after another (sequentially) or all digits at once (simultaneously). There were three number-lengths (four, six, and eight digits) and three exposure times (100, 500, and 1000 msec.). Performance was evaluated from errors and response times, and subjects transfer strategies were examined. Simultaneous displays transferred digits more effectively than sequential ones. Performance was better with shorter numbers or longer exposure times. Subjects transferred only four to five digits accurately, and only when the exposure time was 500 msec. or longer. Their channel capacity approximated 13 bits.
