    Objective: The aim of this laboratory experiment was to demonstrate how taking a longitudinal, multilevel approach can be used to examine the dynamic relationship between subjective workload and performance over a given period of activity involving shifts in task demand.Yeshttps://us.sagepub.com/en-us/nam/manuscript-submission-guideline

    Information Processing in Aviation

    No full text
    This chapter reviews the extant understanding of the fundamental capabilities that humans can contribute to aviation operations. The chapter examines how the pilots adapt to the changing aviation environment as information processing demands shifted from direct perceptual-motor control of the aircraft flight path and attitude to more complex and strategic, higher-level processing enabling the aircraft to safely operate in otherwise untenable regimes (e.g., night flight) and more crowded airspace. How limited human attention is mobilized, allocated, and optimized to meet the myriad challenges of the aviation environment is discussed. The interplay between the essential skills that enable performance and the human biases that can conspire to produce errors is examined. Last, the pragmatic need to characterize the demands of information processing has led to the development of the concepts of mental workload and situation awareness to help guide design and to assess the effectiveness of aviation systems. Considering the extant knowledge of human information processing and emerging technological trends, the chapter looks forward to a likely future aviation system

    A defeasible reasoning framework for human mental workload representation and assessment

    Human mental workload (MWL) has gained importance in the last few decades as an important design concept. It is a multifaceted complex construct mainly applied in cognitive sciences and has been defined in many different ways. Although measuring MWL has potential advantages in interaction and interface design, its formalisation as an operational and computational construct has not sufficiently been addressed. This research contributes to the body of knowledge by providing an extensible framework built upon defeasible reasoning, and implemented with argumentation theory (AT), in which MWL can be better defined, measured, analysed, explained and applied in different human–computer interactive contexts. User studies have demonstrated how a particular instance of this framework outperformed state-of-the-art subjective MWL assessment techniques in terms of sensitivity, diagnosticity and validity. This in turn encourages further application of defeasible AT for enhancing the representation of MWL and improving the quality of its assessment
