Title and Subtitle: Methodology in the assessment of complex human performance: The effects of signal rate on monitoring a dynamic process.

Report Date: April 1969

Authors: Chiles WD, Bruni CB, Lewis RA.

Abstract: Male subjects were tested after extensive training as two five-man 'crews' in an experiment designed to examine the effects of signal rate on the performance of a task involving the monitoring of a dynamic process. Performance was measured using three signal rates with several levels of workload induced by the simultaneous performance of different combinations of tasks involving reaction time, mental arithmetic, pattern discrimination, and group problem solving.

Key Words: PERFORMANCE (HUMAN), VISUAL SIGNALS, MONITORS, DYNAMICS, PROBABILITY, FREQUENCY, REACTION (PSYCHOLOGY), TIME, MEASURING INSTRUMENTS, SIGNAL LIGHTS, NUMERICAL METHODS AND PROCEDURES, STATISTICAL ANALYSIS, STUDENTS, RELIABILITY.
