 | Spatial disorientation (SD) and subsequent loss of situation awareness (LSA) mishaps for military air forces, commercial aviation, and general aviation have an estimated annual cost in the billions of dollars. SD occurs when the pilot has an incorrect perception of the attitude, altitude, or motion of one's own aircraft relative to the earth or other significant objects. One example of the devastating effects of SD is the following mishap: A ... |

| We present a framework within which to understand the causes of chronic susceptibility to disorientation and how it may be resolved. Motorists Disorientation Syndrome is given as an example disorientation syndrome which may occur without sensory or marked psychological disorder and resembles pilots' disorientation. The syndrome may begin with an episode of disorientation or a sensory impairment and thereafter can cause dysfunctional behaviour. A neglected feature of disorientation is that ... |

| Spatial disorientation (SD) is a long recognized problem in aviation environment. During flight the spatial disorientation may appear as a result of inadequate perception of the position or attitude of an aircraft in comparison of the co-ordinate system constituted by the Earth surface. It is extremely difficult to say how often spatial disorientation became the reason of military aircraft accidents 6 but in Poland it is calculated at around 8%. ... |

Our project focused on developing multimedia systems to support human learning, based on cognitive principles and guidelines from cognitive science. The question was not so much whether multimedia makes a difference, but rather how can it best be deployed to make a difference? Specifically, what combinations of media and methods of interaction are most effective ... |

David L. Williams; NAVAL POSTGRADUATE SCHOOL MONTEREY CA

| Why do countries want nuclear weapons? This question has plagued non- proliferation and U.S. intelligence experts since the beginning of the nuclear era. Motivations for nuclear weapons typically are viewed as the product of external variables (perceived insecurity, prestige, etc.). This thesis asserts that a different level of analysis is appropriate. It is a society's beliefs about nuclear technology that at least partially explains nuclear proliferation. The 1939 U.S. decision ... |

| This report reviews theoretical perspectives about how people use and understand information. This is particularly relevant to an information production domain such as military intelligence. We focused on approaches in cognitive psychology and on problem solving in particular. These approaches proved limited in several important ways but specifically because the emphasis in cognitive psychology is information processing rather than information content and on 'toy' problems rather than the pragmatic use ... |

|
| When stimuli presented to the two eyes differ considerably, stable binocular fusion fails, and the subjective percept alternates between the two monocular images, a phenomenon known as binocular rivalry. The influence of attention over this perceptual switching has long been studied, and although there is evidence that attention can affect the alternation rate, its role in the overall dynamics of the rivalry process remains unclear. The present study investigated the ... |

| Breast cancer screening is currently the most reasonable strategy for reducing the impact of breast cancer on women. However, increased perceived risk and psychological distress have been associated with lower screening rates. Thus, this study seeks to: (1) assess the psychological distress of 350 women ages 50 to 85 who receive breast cancer risk appraisal and randomization to immediate or delayed group psychosocial counseling (2) assess their breast cancer screening ... |

| In this paper, we identify domain-specific measures of individual differences in feedback propensities. In a series of studies, we identify the primary dimensions, psychometric characteristics, and construct validation evidence for internal ability, internal propensity, and external propensity for feedback. Confirmatory factor analysis supports the three-dimensional representation. Correlations between the new scales and existing differences of personality are consistent with theoretical predictions. Research that has used the new scales to predict ... |

| This paper reports on a meta-analytic integration of the relation between group cohesiveness and performance. Overall, the cohesiveness- performance effect was highly significant and of small magnitude. Several theoretically informative determinants of the cohesiveness-performance effect were examined. This effect was significantly stronger when cohesiveness was operationalized in terms of measurements of group members' perceptions of cohesiveness than when cohesiveness was operationalized in terms of experimental inductions of cohesiveness. The results ... |

| Perceptual-motor and cognitive processes whereby people perform multiple concurrent tasks have been studied through an overlapping-tasks procedure. During this procedure, two successive choice-region tasks are performed with a variable interval (stimulus onset asynchrony, or SOA) between the beginning of the first and second tasks. Subjects' reaction times (RTs) for Task 2 are typically greater after very short SOAs. The RT increase, called the psychological refractory-period (PRP) effect, reveals basic characteristics ... |

As U.S. defense expenditures are reduced in the 1990's, U.S. allies will be called upon to contribute a greater share to meet common security responsibilities. Japan's government faces a multitude of constraints to increasing defense expenditures placed upon them by the U.S., the Japanese public and Japan's Asian neighbors. Some of these constraints are affected significantly by Japanese perceptions of U.S. commitment ... |

| Charles de Gaulle's foreign and security policy pained and annoyed his American counterparts. Some observers, including his less-than-sympathetic biographer, Don Cook, attribute de Gaulle's actions primarily to the French President's "prejudices, suspicions, and resentments" of his past treatment at the hands of the United States and Great Britain, and a nostalgia for the European system of states of his youth. While there was an element of revenge for past Anglo-Saxon ... |

| Two experiments are reported that use gating methods to examine the role of non-semantic aspects of sentential context in the recognition of phonetic segments. Performance in recognizing syllable-final /s/ and /z/ improves when the syllables are presented to listeners in sentential context as compared to when they are presented in isolation. It appears that listeners are able to use sentential information in order to factor out prosodically based variations in ... |
