Visual attention can select stimuli by size, even in rapid serial visual presentation (RSVP) conditions. This challenges previous findings, suggesting size-based selection is possible under specific circumstances.

Area of Science:

  • Cognitive Psychology
  • Visual Perception
  • Neuroscience

Background:

  • Previous research indicated limitations in visual selection based on stimulus size.
  • The rapid serial visual presentation (RSVP) paradigm was previously thought to preclude size-based attentional selection.

Purpose of the Study:

  • To investigate the effectiveness of size-based visual selection under RSVP conditions.
  • To determine the conditions under which attention to specific sizes is feasible.

Main Methods:

  • Experiments utilized RSVP stimuli with varying spatial configurations and onset characteristics.
  • Participants were tasked with attending to stimuli based on their size.

Main Results:

  • Effective size-based selection was demonstrated in several RSVP conditions.

  • Selection by size proved highly efficient at a single location and possible with 2-4 locations.
  • Size-based selection remained effective over six locations when stimuli lacked abrupt onsets.

    • Conclusions:

    • Contrary to prior research, size-based visual selection is achievable under specific RSVP paradigms.
    • The findings suggest that mandatory properties of spatial attention facilitate size-based selection.
