Summary
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.
