Saccadic eye movements struggle to recognize complete shapes when parts are hidden or missing. The visual system relies more on visible fragments than inferred object outlines for guiding eye movements.

Area of Science:

  • Visual perception
  • Oculomotor control
  • Cognitive neuroscience

Background:

  • Saccadic eye movements precisely localize targets like shapes.
  • Understanding shape representations guiding saccades is crucial.

Purpose of the Study:

  • Investigate how the brain represents object shape for saccadic guidance.
  • Determine if saccades access full shape information despite occlusion or missing parts.

Main Methods:

  • Saccadic localization of partially-occluded and fragmented triangles was tested.
  • A discrimination paradigm assessed accuracy in saccading to inferred full shapes.

Main Results:

  • Occlusion cues were ineffective; saccades targeted visible fragments, not inferred full triangles.

  • Removing vertices (fragmented shapes) improved performance slightly but not to full shape levels.

    • Conclusions:

    • The saccadic system is insensitive to certain shape inference cues.
    • Saccadic representations of occluded objects may rely on retinal image configuration.
