Examining the effects of mental workload and time pressure on cognitive task performance
MetadataShow full item record
In this research, I investigated ways to reliably measure the effects of time pressure on mental workload using physiological measurement techniques and subjective workload assessments, as well as the resultant effects on performance in a cognitively-demanding task. This task involved subjects solving mental arithmetic problems of varying difficulties to induce different workloads. Time pressure has not been systematically researched to the extent of mental workload, but has been observed to affect performance in two contrasting ways: 1) limiting performance in a manner similar to cognitive overload; and by 2) focusing cognitive activities to improve performance.
