Abstract
To assess the relationship between behavioral, subjective and physiological measures of mental workload, 10 adult subjects solved equations with 1,2 or 3 plus or minus operators (the Math Processing subtest of the CTS battery). Following extensive training, individual test sessions were held during which reaction times, subject workload ratings and a set of physiological measures were recorded. Reaction times and subjective workload ratings increased with the number of operators in the equations, but heart rhythm, eye blinks and peripheral temperature showed no systematic relationships to the number of operators. The P-300 event related potential decreased in amplitude and latency and a late positive component recorded at Cz decreased in amplitude and increased in latency as the number of operators in the equations was increased.Keywords
