The purpose of the study was to determine whether visual search can be mediated by an achromatic, or luminance, mechanism in which signals are independent of the chromaticity of the stimuli. Experiments were designed to determine whether variability in the chromaticity of distractor stimuli made it more difficult to search for a target that differed from(More)
OBJECTIVE We sought to determine the optimal focal distance for a semitransparent monocular head-mounted display (HMD) integrated with a flight simulator display and to investigate whether observers experienced visual discomfort or impaired target recognition when using an HMD set at the optimal distance. BACKGROUND When an observer wears a monocular HMD(More)
OBJECTIVE We provide a review and analysis of much of the published literature on visual perception issues that impact the design and use of head-mounted displays (HMDs). BACKGROUND Unlike the previous literature on HMDs, this review draws heavily from the basic vision literature in order to help provide insight for future design solutions for HMDs. (More)
OBJECTIVE We provide a review and analysis of much of the published literature on binocular rivalry that is relevant to the design and use of head-worn displays (HWDs). BACKGROUND This review draws heavily from both the basic vision literature and applied HWD literature in order to help provide insight for minimizing the effects of binocular rivalry when(More)
PURPOSE A driving simulator was used to examine the relationship between motion perception and driving performance. Although motion perception test scores have been shown to be related to driving safety, it is not clear which combination of tests are the best predictors and whether motion perception training can improve driving performance. METHODS In(More)
Motivation-Two decision-making processes have been identified: an analytical process and an intuitive process. One conceptual model of the latter is the Recognition Primed Decision (RPD) model (Klein, 2008). According to this model, decision making in naturalistic contexts entails a situational pattern-recognition process which, if subsequent expectancies(More)

OBJECTIVE The prevalence of anxiety and depressive disorders in people of South Asian origin in the UK is not accurately known. METHOD A population-based study of UK residents from the Indian subcontinent was screened for anxiety and depressive disorders with the Self-Rating Questionnaire (SRQ) and for life events using the brief list of threatening life(More)

Motivation – Validate a System Dynamics model of decision speed for a scenario relevant to an Air Force mission task. Research approach – Extend a decision priming basic research paradigm to a more applied case. Findings/Design – Decision priming was found to occur with more complex stimuli relevant to an air-to-ground target identification scenario. A(More)
