Covert visual attention and extrafoveal information use during object identification.

J M Henderson, A Pollatsek, K Rayner

    Perception & Psychophysics
    |March 1, 1989
    PubMed
    Summary

    Multiple extrafoveal previews offer no more benefit than a single preview for object identification. Extrafoveal information use during visual attention is primarily driven by the next eye movement target.

    Area of Science:

    • Cognitive Psychology
    • Neuroscience
    • Visual Perception

    Background:

    • Understanding how visual attention guides information processing is crucial for cognitive science.
    • Extrafoveal vision, information processed outside the central gaze, plays a role in object identification.
    • The relationship between covert visual attention and the utilization of extrafoveal information remains an active area of research.

    Purpose of the Study:

    • To investigate the impact of multiple extrafoveal previews on object identification.
    • To examine the role of covert visual attention in utilizing extrafoveal visual information.
    • To test a model of extrafoveal information acquisition during visual fixation.

    Main Methods:

    • Three experiments were conducted involving object identification tasks with recorded eye movements.

    Related Experiment Videos

  • Participants viewed arrays of objects, with manipulations in the number and location of visible objects during fixations.
  • Object identification accuracy and fixation durations were measured to assess information processing benefits.

    • Main Results:

    • Experiments 1 and 2 demonstrated that multiple extrafoveal previews provided no significant advantage over a single preview.
    • Experiment 3 provided evidence supporting a model where extrafoveal information is primarily gathered from the next intended fixation location.
    • Fixation time on objects did not improve with additional extrafoveal information.

    Conclusions:

    • The findings suggest that the benefits of extrafoveal information for object identification are limited, even with multiple previews.
    • A sequential attention model is proposed, highlighting the role of upcoming saccades in guiding extrafoveal information acquisition.
    • Covert visual attention appears to prioritize information relevant to the immediate future of visual exploration.
