“…After reviewing a variety of methods, which tended to be labor andtraining intensive, we settled on a simplified cognitive task analysis method designed for use by the layman. Klein Associates developed Applied Cognitive Task Analysis (ACTA) (Militello, Hutton, Pliske, Knight, Klein, and Randel, 1997) for the U.S. Navy as a means of developing course material for Instructional Designers. This methodology provides a set of tools that elicit important cognitive aspects of expert performance, and that are more easily learned than earlier Cognitive Task Analysis methods (Militello, et al, 1997).…”

“…This model was based on data collected from a wide variety of experts through observation and interview techniques. We chose a modified version of the "simulation interview" (Militello, et al, 1997) as our method of choice in applying ACTA to our study.The simulation interview consists of using specific interview techniques to solicit an expert's view of the problem solving process in a specific domain. This interview technique is intended to provide the researcher with specific details of an expert's cognitive processes.…”

“…In this case, incidents were chosen that met three criteria: the incident clearly affected the outcome of the navigation task, the team spent a significant amount of time and effort to make a decision, and the problem appeared to the administrator to be cognitively demanding. The last criterion was purely subjective and was left to the administrator's experience and judgment.We used an interview method based on the critical incident method (Klein, Calderwood, & MacGregor, 1989), and the simulation interview method from AppliedCognitive Task Analysis (ACTA) (Militello, et al, 1997). This method was modified to support the investigation of more limited incidents.…”

DISTRIBUTION / AVAILABILITY STATEMENTApproved for public release; distribution is unlimited. 12b. DISTRIBUTION CODE ABSTRACT (maximum 200 words)Most tasks that are desirable to train in a virtual environment are not tasks that we do alone, but rather are executed collaboratively with one or more team members. Yet little is known about how to construct virtual environment training systems that support collaborative behavior. The purpose of this thesis was to explore methodologies for developing collaborative virtual environments for training. Our approach centered on analyzing task or training specific requirements for the simulation environment. We applied user-centered design techniques to analyze the cognitive processes of collaborative wayfinding to develop interface design guidelines. We utilized the results of our analysis to propose a general model of collaborative wayfinding. This model emphasizes team collaboration and interaction in problem solving and decision-making. We tested the model in the field, using cognitive task analysis methods to study land navigators. This study was intended to validate the use of user-centered design methodologies for the design of collaborative virtual environments. Our findings provide information useful to design, ranging from model enhancement to interface development. We have explored the cognitive aspects of collaborative human wayfinding and design for collaborative virtual environments. Further investigation of design paradigms should include cognitive task analysis and behavioral task analysis. Approved for public release; distribution is unlimited.

ObjectiveCervical spine imaging decision‐making for pediatric traumas is complex and multidisciplinary. Implementing a risk assessment tool has the potential to reduce variation in these decisions and unnecessary radiation exposure for pediatric patients. We sought to determine how emergency department–trauma team dynamics may affect implementation of such a tool.MethodsWe interviewed (pediatric and general emergency physicians, trauma surgeons, neurosurgeons, orthopedic surgeons and ED nurses at 21 hospitals to ascertain how team dynamics affect the pediatric cervical spine imaging decision‐making process. Data were coded following a framework‐driven deductive coding process and thematic analysis was used.ResultsForty‐eight physicians, advanced practice providers, and nurses from 21 hospitals (inclusive of three US regions, trauma levels I–III, and serving towns/cities of various population sizes) were interviewed. Overall, emergency physicians and trauma surgeons indicate being generally responsible for pediatric cervical spine imaging decisions. Conflict often occurs between these specialties due to differential weighting of concerns for missing an injury versus avoiding radiation exposure. Participants described a lack of trust and unclear roles regarding ownership for the final imaging decision. Nurses commonly described low psychological safety that prohibits them from participating in the decision‐making process.ConclusionsImplementation of a standardized risk assessment tool for cervical spine trauma imaging decisions must consider perspectives of both emergency medicine and trauma. Policies to define appropriate use of standardized tools within this team environment should be developed.

The commissioning of a nuclear power plant (NPP) is the last stage in the life cycle of an NPP before commercial operation. Human errors in this stage cannot only harm workers' safety but can also cause damage to system facilities, postpone the commissioning schedule, and become latent problems in the system if the errors are not discovered during the commissioning stage. Therefore, identifying and controlling potential human errors is of great importance at this stage. This study first reviewed
