    • Above and beyond standardization: The role of communication and teamwork in patient handoffs 

      Fouquet, Sarah; Palmer, Evan M.; Keebler, Joseph R.; Lazzara, Elizabeth H.; Chan, Y. Raymond; Riss, Robert (Wichita State University. Graduate School, 2014-04-25)
      Patient handoffs are the transition of patient care from one provider or group of providers to the next (Joint Commission, 2005). Handoffs are important, information rich communication events that are essential for maintaining ...
    • Adding game-like elements to an armored vehicle recognition training 

      Smith, Dustin C.; Turner, Colton (Wichita State University. Graduate School, 2015-04-24)
      Fratricide accidents, or friendly-fire accidents, contribute to a large number of military operations casualties. Gadsden and Outteridge (2006) noted that misidentification caused a large number of these accidents. Therefore, ...
    • Adding game-like elements to an armored vehicle recognition training 

      Smith, Dustin C.; Palmer, Evan M.; Turner, Colton (Wichita State University, 2015-02-15)
      Fratricide, or friendly-fire accidents, account for an overwhelming number of casualties during military operations. Gadsden and Outteridge (2006) examined the varying causes of fratricide across the reported incidents. ...
    • The aperture capture illusion: Misperceived forms in dynamic occlusion displays 

      Palmer, Evan M.; Kellman, Philip J. (American Psychological Association, 2014-04)
      Visual illusions can reveal unconscious representations and processes at work in perception. Here we report a robust illusion that involves the misperception of moving, partially occluded objects. When a dynamically occluded ...
    • Beyond the content: the role of teamwork and communication in patient handoffs 

      Fouquet, Sarah; Lazzara, Elizabeth H.; Chan, Y. Raymond; Riss, Robert (Wichita State University, 2014-02-13)
      Patient handoffs are the transition of patient care from one provider or group of providers to the next (Joint Commission, 2005). Handoffs are important, information rich communication events that are essential for ...
    • Differentiating global and local contour completion using a dot localization paradigm 

      Carrigan, Susan B.; Palmer, Evan M.; Kellman, Philip J. (American Psychological Association, 2016-12)
      Competing theories of partially occluded object perception (amodal completion) emphasize either relatively local contour relationships or global factors such as symmetry. These disparate theories may reflect 2 separate ...
    • Documentation workflow in a pediatric emergency department 

      Fouquet, Sarah (Wichita State University, 2016-04-29)
      The pediatric emergency department (ED) is a complex environment where physicians perform multiple tasks under intense time pressure and are interrupted more often than in any other hospital department. Documentation is ...
    • Estimation of mental workload using saccadic eye movements in a free-viewing task 

      Tokuda, Satoru; Obinata, Goro; Palmer, Evan M.; Chaparro, Alex (IEEE, 2011-07)
      This study proposes a new method to automatically estimate a person's mental workload (MWL) using a specific type of eye movements called saccadic intrusions (SI). Previously, the most accurate existing method to estimate ...
    • Evaluation of MILSTD 2525 glyph features in a visual search paradigm 

      Siva, Navaneethan; Chaparro, Alex; Palmer, Evan M. (2014-10)
      MILSTD 2525 is a document that outlines the composition and use of a set of standardized symbology by the US Department of Defense to represent vehicles, equipment and personnel on tactical interfaces. These symbols are ...
    • Evaluation of the presence of a face search advantage in Chernoff faces 

      Sivagnanasundaram, Navaneethan; Chaparro, Alex; Palmer, Evan M. (2013-09)
      Chernoff faces (Chernoff, 1973) are an early attempt at large scale multivariate data representation and are based on underlying assumptions that have not been empirically tested. This study investigated i) whether data ...
    • Examining aviation navigation display symbology in visual search 

      Sivagnanasundaram, Navaneethan; Palmer, Evan M.; Chaparro, Alex (National Academies of Sciences, Engineering, and Medicine, 2016)
      This paper investigates properties of air traffic glyphs that may affect speed and accuracy when a navigation display is being searched. Four of these properties were explored: (a) the amount of information represented, ...
    • Exploring website gist through rapid serial visual presentation 

      Owens, Justin W.; Chaparro, Barbara S.; Palmer, Evan M. (Springer Nature, 2019-11-20)
      Background: Users can make judgments about web pages in a glance. Little research has explored what semantic information can be extracted from a web page within a single fixation or what mental representations users have ...
    • Frequency characteristics of eye movements during a cognitively demanding task 

      Tokuda, Satoru; Obinata, Goro; Palmer, Evan M.; Chaparro, Alex (Wiley-Blackwell, 2012-09)
      This study investigated the relation between cognitive load (CL) and eye movement frequency characteristics. Previously, eye gaze has been known to have more gaze deviation when the person is engaged in a cognitively ...
    • Gamified low-prevalence vigils 

      Miranda, Andrew T. (Wichita State University, 2015-12)
      The vigilance decrement has been a well-studied human factors problem since World War II (Mackworth, 1948). A more recently discovered and fundamentally similar problem is the low-prevalence effect in visual search (e.g., ...
    • Gaze pattern differences between objective and subjective search of e-commerce web pages 

      Nguyen, Duy; Owens, Justin W.; Chaparro, Alex; Chaparro, Barbara S.; Palmer, Evan M. (Sage, 2012-09)
