Cognitive Systems Engineering
Cognitive systems engineering (CSE) is a field of study that examines the intersection of people, work, and technology, with a focus on safety-critical systems. The central tenet of cognitive systems engineering is that it views a collection of people and technology as a single unit that is capable of cognitive work, which is called a joint cognitive system. CSE draws on concepts from cognitive psychology and cognitive anthropology, such as Edwin Hutchins's distributed cognition, James Gibson's ecological theory of visual perception, Ulric Neisser's ''perceptual cycle,'' and William Clancey's situated cognition. CSE techniques include cognitive task analysis and cognitive work analysis. Origins Three Mile Island Cognitive systems engineering emerged in the wake of the Three Mile Island (TMI) accident. At the time, existing theories about safety were unable to explain how the operators at TMI could be confused about what was actually happening inside of the plant. Followi ...

Cognitive Psychology
Cognitive psychology is the scientific study of mental processes such as attention, language use, memory, perception, problem solving, creativity, and reasoning. Cognitive psychology originated in the 1960s in a break from behaviorism, which held from the 1920s to 1950s that unobservable mental processes were outside the realm of empirical science. This break came as researchers in linguistics and cybernetics, as well as applied psychology, used models of mental processing to explain human behavior. Work derived from cognitive psychology was integrated into other branches of psychology and various other modern disciplines like cognitive science, linguistics, and economics. The domain of cognitive psychology overlaps with that of cognitive science, which takes a more interdisciplinary approach and includes studies of non-human subjects and artificial intelligence. History Philosophically, ruminations on the human mind and its processes have been around since the times of the a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cognitive Work Analysis
Cognitive work analysis (CWA) is a framework that was developed to model a complex sociotechnical system. Modeling of system constraints The framework models different types of constraints, building a model of how work could proceed within a given work system. The focus on constraints separates the technique from other approaches to analysis that aim to describe how work is actually conducted, or prescribe how it should be conducted. The CWA approach can be used to describe the constraints imposed by the purpose of a system, its functional properties, the nature of the activities that are conducted, the roles of the different human actors, and their cognition skills and strategy. Application Rather than offer a prescribed methodology, the CWA framework instead acts as a toolkit that can be used either individually or in combination with one another, depending upon the analysis needs. These tools are divided between phases. The exact names and scopes of these phases differ sligh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grounding In Communication
Grounding in communication is a concept proposed by Herbert H. Clark and Susan E. Brennan. It comprises the collection of "mutual knowledge, mutual beliefs, and mutual assumptions" that is essential for communication between two people. Successful grounding in communication requires parties "to coordinate both the content and process". The concept is also common in philosophy of language. Elements of theory Grounding in conversation Grounding in communication theory has described conversation as a form of collaborative action. While grounding in communication theory has been applied to mediated communication, the theory primarily addresses face-to-face conversation. Groups working together will ground their conversations by coming up with common ground or mutual knowledge. The members will utilize this knowledge in order to contribute to a more efficient dialogue. Grounding criterion is the mutual belief between conversational partners that everyone involved has a clear enou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1994 Black Hawk Shootdown Incident
The 1994 Black Hawk shootdown incident, sometimes referred to as the Black Hawk Incident, was a friendly fire incident over northern Iraq that occurred on 14 April 1994 during Operation Provide Comfort (OPC). The pilots of two United States Air Force (USAF) F-15 fighter aircraft, operating under the control of a USAF airborne warning and control system (AWACS) aircraft, misidentified two United States Army UH-60 Black Hawk helicopters as Iraqi Mil Mi-24 "Hind" helicopters. The F-15 pilots fired on and destroyed both helicopters, killing all 26 military and civilians aboard, including personnel from the United States, United Kingdom, France, Turkey, and the Kurdish community. A subsequent USAF investigation blamed the accident on several factors. The F-15 pilots were faulted for misidentifying the helicopters as hostile. Also, the crew members of the AWACS aircraft were blamed for their inaction in failing to exercise appropriate control and for not intervening in the situation. ...

Space Shuttle Challenger Disaster
On January 28, 1986, the broke apart 73 seconds into its flight, killing all seven crew members aboard. The spacecraft disintegrated above the Atlantic Ocean, off the coast of Cape Canaveral, Florida, at 11:39a.m. Eastern Time Zone, EST (16:39 Coordinated Universal Time, UTC). It was the first fatal accident involving an List of space programs of the United States, American spacecraft in flight. The mission, designated STS-51-L, was the tenth flight for the Space Shuttle orbiter, orbiter and the twenty-fifth flight of the Space Shuttle fleet. The crew was scheduled to deploy a communications satellite and study Halley's Comet while they were in orbit, in addition to taking school teacher Christa McAuliffe into space. The latter resulted in a higher than usual media interest and coverage of the mission; the launch and subsequent disaster were seen live in many schools across the United States. The cause of the disaster was the failure of the two O-ring seals in a joint in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diane Vaughan
Diane Vaughan is an American sociologist and professor at Columbia University. She is known for her work on organizational and management issues, in particular in the case of the space shuttle ''Challenger'' Disaster. In the understanding of safety and risk, Vaughan is perhaps best known for coining the phrase "normalization of deviance", which she has used to explain the sociological causes of the '' Challenger'' and ''Columbia'' disasters. Vaughan defines this as a process where a clearly unsafe practice comes to be considered normal if it does not immediately cause a catastrophe: "a long incubation period efore a final disasterwith early warning signs that were either misinterpreted, ignored or missed completely." In the study of relationships, Vaughan is known for her research into the process of relationship breakups. Vaughan received her Ph.D. in sociology from Ohio State University and is a laureate of the ''Public Understanding of Sociology'' ''Award'', of the America ...

Lucy Suchman
Lucy Suchman is a Professor of Anthropology of Science and Technology in the Department of Sociology at Lancaster University, in the United Kingdom. Her current research extends her longstanding critical engagement with the field of human-computer interaction to the domain of contemporary war fighting, including problems of ‘situational awareness’ in military training and simulation, and in the design and deployment of automated weapon systems. At the center of this research is the question of whose bodies are incorporated into military systems, how and with what consequences for social justice and the possibility for a less violent world. Suchman is a member of International Committee for Robot Arms Control and the author of the blog dedicated to the problems of ethical robotics and 'technocultures of humanlike machines' Before coming to Lancaster, she worked for 22 years at Xerox's Palo Alto Research Center (PARC) in California, where she held the positions of principal ...

Naturalistic Decision-making
The naturalistic decision making (NDM) framework emerged as a means of studying how people make decisions and perform cognitively complex functions in demanding, real-world situations. These include situations marked by limited time, uncertainty, high stakes, team and organizational constraints, unstable conditions, and varying amounts of experience. The NDM framework and its origins The NDM movement originated at a conference in Dayton, Ohio in 1989, which resulted in a book by Gary Klein, Judith Orasanu, Roberta Calderwood, and Caroline Zsambok. The NDM framework focuses on cognitive functions such as decision making, sensemaking, situational awareness, and planning – which emerge in natural settings and take forms that are not easily replicated in the laboratory. For example, it is difficult to replicate high stakes, or to achieve extremely high levels of expertise, or to realistically incorporate team and organizational constraints. Therefore, NDM researchers rely on cogn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Macrocognition
Macrocognition indicates a descriptive level of cognition performed in natural instead of artificial (laboratory) environments. This term is reported to have been coined by Pietro Cacciabue and Erik Hollnagel in 1995. However, it is also reported that the term was used in the 1980s in European Cognitive Systems Engineering research. Possibly the earliest reference is the following, although it does not use the exact term "macrocognition": A macro-theory is a theory which is concerned with the obvious regularities of human experience, rather than with some theoretically defined unit. To refer to another psychological school, it would correspond to a theory at the level of Gestalten. It resembles Newell’s suggestion for a solution that would analyse more complex tasks, although the idea of a macro-theory does not entail an analysis of the mechanistic materialistic kind which is predominant in cognitive psychology. Thus we should have a macro-theory of remembering rather than of mem ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
In Situ
''In situ'' (; often not italicized in English) is a Latin phrase that translates literally to "on site" or "in position." It can mean "locally", "on site", "on the premises", or "in place" to describe where an event takes place and is used in many different contexts. For example, in fields such as physics, geology, chemistry, or biology, ''in situ'' may describe the way a measurement is taken, that is, in the same place the phenomenon is occurring without isolating it from other systems or altering the original conditions of the test. The opposite of ''in situ'' is ''ex situ''. Aerospace In the aerospace industry, equipment on-board aircraft must be tested ''in situ'', or in place, to confirm everything functions properly as a system. Individually, each piece may work but interference from nearby equipment may create unanticipated problems. Special test equipment is available for this ''in situ'' testing. It can also refer to repairs made to the aircraft structure or flight con ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
