Objects that direct visuospatial attention produce the search advantage for facing dyads

Area of Science:

• Cognitive Psychology
• Visual Perception
• Human-Computer Interaction

Background:

• Facing pairs of individuals are found faster in visual search than back-to-back pairs.
• Two theories explain this: social interaction processing vs. directional cuing by body parts.

Purpose of the Study:

• To test whether the search advantage for facing dyads is due to social processing or directional cuing.
• To determine if the effect extends to non-social objects.

Main Methods:

• Replicated the search advantage using non-social objects.
• Used a cuing paradigm to assess the role of visuospatial attention direction.

Main Results:

• The visual search advantage for facing pairs was replicated with non-social objects.
• Object categories that produced a stronger cuing effect also showed a stronger search advantage.
• The strength of the cuing effect correlated with the search advantage.

Conclusions:

• Results support the directional cuing account of the visual search advantage for facing dyads.
• The ability of objects to direct visuospatial attention explains the effect, not social interaction processing.
