“…An observation study with a video-based analysis [21] would help to clarify why dentists who used Pd in this study spent more time on each task. Also a paper-based task analysis [22] or actual time measurements on patient visits [23] could give more interesting information on the variability of working time in dental work tasks.…”

Proprioceptive derivation (Pd), a new method of organising a dentist workstation as well as a working procedure, was introduced to Thailand. The aim of this study was to assess the working conditions and the attitude to Pd among experienced users. Questionnaires were distributed among 12 dentists. The results showed that all dentists chose to work in a sitting posture and mostly worked without breaks between patients. They spent less time on dental examination and crown and bridge therapy tasks. Solving problems in patients with physical limitations resulted in a low stress level. Seven dentists (58.3%) always used Pd and liked it. Five dentists (41.7%) sometimes used Pd, with 3 of them liking it. Only 2 dentists, who sometimes used Pd, did not like it because it could not cover all dental tasks and treatment, and it was difficult and complex.

“…A basic search in Medline conducted in November 2013 returned only two articles and one poster presented at the American Dental Education Association (ADEA) Annual Session & Exhibition 4 , 12 , 13 . In an article published in 2000, Cameron et al reported on their study that used a CTA to identify all the knowledge and tasks that are important to dental hygiene 12 . In isolating these discrete tasks, the authors designed nine cases, expecting that the solutions would differ depending on whether the participant was an expert, competent, or novice dental hygienist.…”

The purpose of this study was to explore the use of cognitive task analysis to inform the teaching of psychomotor skills and cognitive strategies in clinical tasks in dental education. Methods used were observing and videotaping an expert at one dental school thinking aloud while performing a speciic preclinical task (in a simulated environment), interviewing the expert to probe deeper into his thinking processes, and applying the same procedures to analyze the performance of three second-year dental students who had recently learned the analyzed task and who represented a spectrum of their cohort's ability to undertake the procedure. The investigators sought to understand how experts (clinical educators) and intermediates (trained students) overlapped and differed at points in the procedure that represented the highest cognitive load, known as "critical incidents." Findings from this study and previous research identiied possible limitations of current clinical teaching as a result of expert blind spots. These indings coupled with the growing evidence of the effectiveness of peer teaching suggest the potential role of intermediates in helping novices learn preclinical dentistry tasks.

“…Cognitive analyses that capture the knowledge and strategies of domain practitioners have application beyond design. For example, they have been used to support development of training (Johnson et al, 2006;O'Hare, Wiggins, Williams, & Wong, 1998;Schaafstal, Schraagen, & van Berlo, 2000;Seamster, Redding, & Kaempf, 1997) as well as specification of proficiency evaluation requirements (Cameron et al, 2000). More recently, CTAs have been used as a means to capture domain expertise for archival purposes.…”

shooting down of Iran Air Flight 655 by the USS Vincennes) provided evidence regarding the need for specific attention to the cognitive activities associated with complex system control, as well as the impetus for research and methodological developments in these areas. Since that time, numerous researchers and practitioners have put forth methodologies intended to explicitly identify the requirements of cognitive work so as to be able to anticipate contributors to performance problems (e.g., sources of high workload, contributors to error) and specify ways to improve individual and team performance, be it through new forms of training, user interfaces, or decision aids. These methodologies stem from, and extend, a century of research and applied methodologies that have focused on the improvement of human work through systematic analysis. This tradition can be traced back to early studies in areas of scientific management that put forward the notion that work could be decomposed into fundamental, repeatable components (Taylor, 1911). Additional advances in work measurement identified fundamental motions in work (e.g., grasp, reach), as well as unnecessary or inefficient motions, and developed innovative methodologies for work analysis (e.g., using motion pictures; Gilbreth & Gilbreth, 1919). The focus of these early methods on observable, physical work elements was well suited to the extensively manual work of the day. Refinements and applications of time-andmotion study, such as the development of predetermined time systems (Sellie, 1992), continued through much of the 20th century, providing a framework for task analysis methods that allowed the physical, perceptual, and cognitive demands of task components to be compared against human capabilities. Methods for examining cognitive work emerged as an adaptation and extension of these techniques in response to fundamental shifts in work that were driven by advances in automation and computerization, from primarily manual, observable activities (or routinized interactions with technology) to complex (and more hidden) cognitive activities, such as monitoring, planning, problem solving, and deciding (Schraagen, Chipman, & Shalin, 2000). 4 Reviews of Human Factors and Ergonomics, Volume 3 Figure 1.1. A cognitive analysis requires consideration of two perspectives: examination of domain characteristics and constraints that impose cognitive demands on domain practitioners, which include components of the task, technical system, social and organizational structure, and physical environment; and examination of the goals, knowledge, skills, and strategies that domain practitioners utilize in response.
