Now you see it, now you don't: representational pseudoneglect during computer maze navigation

Area of Science:

• Cognitive Psychology
• Neuroscience
• Human Spatial Navigation

Background:

• Pseudoneglect describes an attentional bias towards the left in near space, shifting rightward in far space.
• This spatial asymmetry impacts real-world activities like navigation, causing rightward deviations when passing through openings.
• A representational form of pseudoneglect, involving leftward attention shifts for memory-based stimuli, has been previously observed.

Purpose of the Study:

• To investigate the existence of representational pseudoneglect within a simulated navigation context.
• To determine if attentional biases differ between perceptual and representational tasks in virtual navigation.
• To explore the impact of memory load on spatial attention during simulated navigation.

Main Methods:

• Participants navigated through virtual doorways or lines in a simulated environment.
• Tasks included perceptual trials (stimulus remained visible) and representational trials (stimulus disappeared).
• Navigation paths were analyzed for directional biases, specifically rightward deviations.

Main Results:

• Significant rightward biases were observed in both perceptual and representational trials for both line and doorway conditions.
• These rightward biases were more pronounced during the representational trials compared to perceptual trials.
• The findings suggest an exacerbation of attentional shifts towards the right when stimuli must be held in memory.

Conclusions:

• Representational pseudoneglect appears to manifest in simulated navigation environments.
• Increased cognitive load associated with memory representation intensifies rightward attentional shifts.
• These results highlight the role of memory processes in modulating spatial attention during navigation.
