TL;DR: The case study illustrates the utility of cognitive work analysis models in the design of large-scale, first-of-a-kind systems, and presents new design artifacts that link concepts used in cognitive analyses to those used in systems engineering for more effective integration within the systems engineering process.
Abstract: This paper describes the integration of cognitive analysis into the early stages of design of a new, large-scale system--a next generation US Navy Surface combatant. Influencing complex system designs in ways cognizant of human-system integration principles requires work products that are timely and tightly coupled to other elements of the design process. Because analyses were conducted simultaneously with the design processes regarding ship functionality and staffing, it was necessary to select and adapt cognitive work analysis methods to fit the demands of a time pressured and information-limited design situation. Interviews were conducted and analyzed based on aspects of an abstraction hierarchy and control task models. An abstraction hierarchy, a series of cross-linked matrices, and a set of decision ladder models were developed to provide a principled mapping between system function decompositions produced by system engineering teams and cognitive tasks, information needs, automation requirements, and concepts for displays. Cross-referencing the matrices supported design traceability and facilitated the integration of cognitive analyses with functional analyses being performed by other design teams. Results fed into design recommendations with respect to level of automation, human roles and initial display prototypes for the ship combat command center. The case study illustrates the utility of cognitive work analysis models (specifically, abstraction hierarchies and decision-ladder models) in the design of large-scale, first-of-a-kind systems, and presents new design artifacts that link concepts used in cognitive analyses to those used in systems engineering for more effective integration within the systems engineering process.

TL;DR: In this article, the authors argue for the incorporation of an individual differences approach into human factors/ergonomics research and practice, arguing that consideration of individual differences will lead to a more inclusive human factors, in which the properties of the human are described in a level of detail commensurate with the display and controls.
Abstract: This paper argues for incorporation of an individual differences approach into human factors/ergonomics research and practice. Description of the systematic variation in the human portion (e.g. cognitive and personality traits; motivational and emotional states) of human–technology systems can complement the existing design methods (e.g. task analysis) to yield better models of system performance and improve system design and operation. Individual differences research should not and need not be atheoretical and opportunistic and applications should not and need not be restricted to selection. Instead, consideration of individual differences will lead to a more inclusive human factors/ergonomics in which the properties of the human are described in a level of detail commensurate with the properties of the displays and controls. Three theories are described and their implications for human factors/ergonomics are discussed. Key issues for future research and practice are identified, including a set of guidel...

TL;DR: An interesting trade-off effect was observed between linguistic complexity and grammatical accuracy in the students' e-mail writing, indicating the complexity of the second language writing process.

TL;DR: This paper examined the mediating role of task complexity in the relationship between core self-evaluations (CSE) and satisfaction and found that people with higher CSE actually choose/seek higher levels of complexity on their tasks, which directly or indirectly increases their task/work satisfaction.

TL;DR: This paper will define and illustrate the various components of task knowledge and attempt to show the functional relationship between task knowledge, specifically “task knowledge” and autonomous learning.
