TL;DR: Results from a survey and a workshop show that there is a need for methodologies that systematically address the cognitive factors of complex task situations.
Abstract: : The development of support of decision making processes in complex systems requires a systematic approach based upon knowledge of the human's role, capabilities, and the tasks to be performed. Results from a survey and a workshop show that there is a need for methodologies that systematically address the cognitive factors of complex task situations. COADE provides the developer and cognitive specialist with an approach to the development of cognitively-centered systems. The COADE framework comprises a set of activities for cognitive analysis, design and evaluation. Analysis activities result in the specification of cognitive requirements; design activities translate those into design requirements; evaluation activities control the quality of the intermediate and final products of the development process.

TL;DR: This chapter presents an overview of the current state of cognitive task analysis (CTA) in research and practice, and describes research on the impact of CTA and synthesizes a number of studies and reviews pertinent to issues underlying knowledge elicitation.
Abstract: This chapter presents an overview of the current state of cognitive task analysis (CTA) in research and practice. CTA uses a variety of interview and observation strategies to capture a description of the explicit and implicit knowledge that experts use to perform complex tasks. The captured knowledge is most often transferred to training or the development of expert systems. The first section presents descriptions of a variety of CTA techniques, their common characteristics, and the typical strategies used to elicit knowledge from experts and other sources. The second section describes research on the impact of CTA and synthesizes a number of studies and reviews pertinent to issues underlying knowledge elicitation. In the third section, we discuss the integration of CTA with training design. Finally, in the fourth section, we present a number of recommendations for future research and conclude with general comments.

TL;DR: An Affect and Belief Adaptive Interface System (ABAIS) designed to compensate for performance biases caused by users’ affective states and active beliefs and provides a generic adaptive framework for integrating a variety of user assessment methods.
Abstract: We describe an Affect and Belief Adaptive Interface System (ABAIS) designed to compensate for performance biases caused by users' affective states and active beliefs. The ABAIS architecture implements an adaptive methodology consisting of four steps: sensing/inferring user affective state and performance-relevant beliefs; identifying their potential impact on performance; selecting a compensatory strategy; and implementing this strategy in terms of specific GUI adaptations. ABAIS provides a generic adaptive framework for integrating a variety of user assessment methods (e.g. knowledge-based, self-reports, diagnostic tasks, physiological sensing), and GUI adaptation strategies (e.g. content- and format-based). The ABAIS performance bias prediction is based on empirical findings from emotion research combined with detailed knowledge of the task context. The initial ABAIS prototype was demonstrated in the context of an Air Force combat task, used a knowledge-based approach to assess the pilot's anxiety level, and adapted to the pilot's anxiety and belief states by modifying selected cockpit instrument displays in response to detected changes in these states.
