|
 | Situational judgment tests have been developed in the fields of Industrial/Organizational and Cognitive Psychology to predict performance and to evaluate theories of cognition. Production of these scales has usually required the opinions of subject matter experts to produce scoring keys or criterion data to compute empirically based standards. A simpler, more elegant procedure is considered that allows examinee responses to be scored as deviations from the consensus defined by the ... |

|
| Adapting instructional content to match the background knowledge of the student has been a long-standing goal of student modeling and tutoring (Bruner, 1966; Burton & Brown, 1979). To this end, cognitive scientists have developed student models that rely on manual knowledge bases relevant to the particular instructional task at hand. Normally, these include domain content, instructional content, models of student misconceptions, and more. While tailoring instruction to the learner has ... |

|
| The goal of the project was to provide preliminary insight into the process of tacit knowledge acquisition and to support the development of tools to assess the use of various knowledge-acquisition processes in solving practical leadership problems. These requirements were met by (a) reviewing relevant theory and research on tacit knowledge, leadership, and knowledge acquisition; (b) reporting results of analyses performed on free text responses ... |

|
| The accurate location of one's (sometimes virtual) egocenter in a geometric space is of critical importance for immersion technologies. Self - location is a relatively unexplored component of size and distance estimations. This experiment was conducted to investigate the role of field of view (FOV) and observer eye station points (ESP) in the perception of the location of one's egocenter (the personal viewpoint) in virtual space. Fifty students viewed an ... |

| In this paper, we address many aspects of Intelligent Tutoring Systems (ITS) in our search for answers to the following main questions; (a) What are the precursors of ITS? (b) What does the term mean? (c) What are some important milestones and issues across the 20+ year history of ITS? (d) What is the status of ITS evaluations? and (e) What is the future of ITS? We start with an ... |

|
| The Army needs to provide retention training in foreign languages for several military occupational specialties (MOS). With limited time and trainers to do so, developing computer training systems to support the training requirement is a viable solution. However, these computer systems need advanced technology such as Artificial Intelligence and natural language processing methods in order to deliver successful language instruction. We review the state-of-the-art technology in this report. Keywords: Artificial ... |

|
| Today's Army is highly dependent upon computer technology. Computers with specially designed applications software or command languages are integral to recruiting and record keeping, education and training, and maintenance and use of complex weapon systems. Since command languages are used in a wide variety of Army jobs, most soldiers will require training for at least one command language at some point in their Army career. The development of effective training ... |

|
| Smart Technology represents the application of cognitive and computer science to Army training. A major component of this technology is intelligent tutors. The authors discuss differences between intelligent and conventional CAI and emphasize the current status of intelligent tutors. Also discussed is ARI's effort to produce Smart Technology for CAI developers. The authors contend that most conventional CAI is undersophisticated and that this problem can be corrected by producing Smart ... |

| EFFECT OF DURATION ON AMPLITUDE DISCRIMINATION IN NOISE. |

|
 | Amplitude-discrimination performance is found to be independent of the duration of the signals to be discriminated for durations ranging from 20 to 200 msec provided that the ratio of signal energy to noise-power density is kept constant. If the ratio of signal energy to noise-power density is manipulated by altering either the noise-power density or the signal duration, then discrimination performance is also independent of that ratio once it exceeds ... |

|
| Leshowitz and Raab (1967) suggest that detection performance remains constant when the increment energy is fixed in spite of wide variation in both signal level and duration. Extension of the observations used to support this suggestion indicate that changes in performance result from changing signal duration even when the increment energy remains constant. (Author) |
