    Change blindness: eradication of gestalt strategies

    Arrays of eight, texture-defined rectangles were used as stimuli in a one-shot change blindness (CB) task where there was a 50% chance that one rectangle would change orientation between two successive presentations separated by an interval. CB was eliminated by cueing the target rectangle in the first stimulus, reduced by cueing in the interval and unaffected by cueing in the second presentation. This supports the idea that a representation was formed that persisted through the interval before being 'overwritten' by the second presentation (Landman et al, 2003 Vision Research 43149–164]. Another possibility is that participants used some kind of grouping or Gestalt strategy. To test this we changed the spatial position of the rectangles in the second presentation by shifting them along imaginary spokes (by ±1 degree) emanating from the central fixation point. There was no significant difference seen in performance between this and the standard task [F(1,4)=2.565, p=0.185]. This may suggest two things: (i) Gestalt grouping is not used as a strategy in these tasks, and (ii) it gives further weight to the argument that objects may be stored and retrieved from a pre-attentional store during this task

    Attention Allocation of Dynamic Icons on Mobile App Interfaces

    The interface serves as the primary channel for interaction between users and mobile apps, making interface design critical for a successful user experience. To enhance the design language of app interfaces, motion graphics have been used due to their unique appeal. However, mobile usage patterns and interface sizes pose challenges in transmitting information effectively. Thus, the question of how to effectively apply motion graphics to meet users\u27 needs and reflect design value remains a pressing concern for interface designers. To address this, this study focuses on the research of dynamic icons in app interfaces and employs the user\u27s cognitive mechanism as a theoretical basis to explore the influence boundary of dynamic icons\u27 core feature. Specifically, an eye-tracking experiment was conducted to study the impact of dynamic icon attention under various experimental conditions. Through the analysis of the distribution characteristics of user attention, it was found that the influence of dynamic icons on user attention varied with changes in the number of dynamic icons. Moreover, the number of dynamic icons played a significant role in regulating changes in a user\u27s information processing mode. These changes ultimately affect the attention of dynamic icons. This research provides a crucial point of reference for future motion graphics interface design and implementation, as well as a more efficient way to enhance user experiences in mobile app user interfaces

    This research presents an innovative approach to improving visual-spatial attention using a research tool based on the web. Recognizing the significant role visual-spatial attention plays in everyday life and cognitive function for humans, this research was undertaken with the aim of developing a user-friendly, accessible web-based tool called Attention Visual (attentionvisual.com) to enhance this crucial cognitive skill. This tool also facilitates data collection, potentially accelerating the pace and enhancing the quality of related research. Both qualitative and quantitative methods were utilized for data collection and analysis. In order to stimulate improvements in visual-spatial attention, the tool’s algorithm was structured to adjust task difficulty according to the user’s performance; heightened performance would yield more challenging tasks, whereas lower performance would result in easier tasks, fostering an adaptive and progressive learning environment. The main hypothesis that underlies this research was that regular use of this tool could result in measurable enhancements in visual-spatial attention. This has potential benefits for various population groups, from athletes to individuals with certain cognitive conditions. The results of the research validate this hypothesis, demonstrating the effectiveness of the webbased tool in enhancing visual-spatial attention and indicating that the design elements of the tool have a positive impact on user performance. The research additionally highlighted a wide range of participant diversity, thanks to the online nature of the tool, enhancing the robustness and generalizability of the data collected. These findings contribute significantly to the fields of cognitive science, neuroplasticity, and digital tool development, offering valuable insights for future research. They demonstrate the effectiveness of web-based tools in cognitive science research and suggest potential avenues for future investigation, such as exploring other aspects of visual cognition or the application of such tools in practical settings like cognitive therapy and rehabilitation

    Eye-Tracking in the Study of Visual Expertise: Methodology and Approaches in Medicine

    Get PDF
    Eye-tracking is the measurement of eye motions and point of gaze of a viewer. Advances in this technology have been essential to our understanding of many forms of visual learning, including the development of visual expertise. In recent years, these studies have been extended to the medical professions, where eye-tracking technology has helped us to understand acquired visual expertise, as well as the importance of visual training in various medical specialties. Medical decision-making involves a complex interplay between knowledge and sensory information, and the study of eye-movements can reveal the mechanisms involved in acquiring the visual component of these skills. Eye-tracking studies have even been extended to develop computational models of procedures for “expert” skill assessment, and to eliminate potential sources of error in image-based diagnostics. This review will examine the current eye-tracking frontier for the study of visual expertise, with specific application to medical professions

    Eyetracking methodology in SCMC: a tool for empowering learning and teaching

    Get PDF
    Computer-assisted language learning, or CALL, is an interdisciplinary area of research, positioned in tension between science and social science, computing and education, linguistics and applied linguistics. This paper argues that by appropriating methods originating in some areas of CALL-related research, for example, HCI or psycho-linguistics, the agenda of 'attention-focus' research can be shifted from a cognitive perspective to a learner-centred approach, understanding online language learning and teaching spaces as mediated by technology, second/foreign language, and online teaching culture. Taking a method that has traditionally been used within a positivist paradigm, the authors exemplify the potential of eyetracking to progress online language learning research - extending it in ways compatible with a sociocultural paradigm. This is evidenced by two pioneering studies in which an innovative combination of methods allows participants, whose gaze focus during synchronous computer-mediated communication (SCMC) has been recorded, to reflect back on their involvement. Eyetracking is combined with stimulated recall interviews that trigger deep reflection on learner and teacher strategies by directing participants’ recollections on their attention focus. The rich, multifaceted results shown by this original and innovative use of eyetracking methods in a sociocultural framework direct a way forward in researching online learning by integrating insider and outside views coherently and systematically
