Human cognition, behaviour, and performance in an on-going dynamic task

This thesis’ experiment directed participants to drive a simulator while having their vision obstructed for various time intervals. The aim was to evaluate the effects that visual obstructions have on participants’ driving performance, subjective workload, and biological responses. Interviews were conducted to identify what strategies participants used to cope with the visual obstructions. This thesis has implications for defence domains, proposing that when multitasking within a vehicle, individuals will experience task performance decrements if they disengage from one task for 3 seconds or longer. Lastly, merging different types of data can develop better predictors of performance.
