Original publisher: Orlando, FL: Technology-Based Training Research Unit, U.S. Army Research Institute for the Behavioral and Social Sciences, [2007] OCLC Number: (OCoLC)231322938 Subject: Military education -- United States. Excerpt: ... modality that can provide spatial locations, however with potential for performance costs ( Wickens & Liu, 1988 ). The purpose of this research effort is to determine if the user can successfully focus attention on specific spatial locations of the visual scene when cued from either visual, auditory, tactile, or a combination of modalities, if there are any differences when the user is cued using similar cues but with no specific spatial location information, and if the user can be cued to focus attention of differing breadths from different cue specificities. The following section of this paper will summarize the literature, first from a basic level describing the theories and models of attention, then next from a more specific level describing the research findings from more recent work on orienting attention. For years the limits of human attention have intrigued philosophers, theorists, and researchers. Exploring and explaining the processes underlying the causes of these limitations provides invaluable information that helps determine what types of situations are safe and, more importantly, unsafe for human operators. One such example is the maximum number of airplanes an air-traffic controller should have to coordinate ( Hopkin, 1995 ). Other situations may be unsafe not due to the number of items required to monitor but because of the combination of one situation task with another ( Wickens, 1984 ). UPS and FedEx employees drive trucks to deliver packages to addresses they have never visited before. Therefore, navigation is an important aspect of their job. However, navigation aids like global positioning systems ( GPS ) and other computer aided visual maps may contribute to distraction to the main task of driving
