Abstract

Time perception has been cited as a good measure of workload because it seldom interferes with performance of tasks that do not require time estimation, is easy to implement, and is sensitive to task difficulty (Hart, 1975a; Zakay & Shub, 1998). It was hypothesized that duration productions could be used to measure workload caused by two word tasks that would interfere with one another as outlined by Wickens' (1980) multiple resource theory. To test this hypothesis participants estimated a 15 second duration while performing a visual animal name detection task, along with an auditory animal name detection task, or a tone change task. The mean duration produced for the condition with two word tasks was not significantly different from the duration produced for the condition with a word task and a tone task. There was also interference between tasks that should not have produced interference. The results do not support the use of the concurrent duration production method to measure the workload caused by dual nontemporal task interference.
