Mentalizing and self-other distinction in visual perspective taking: the analysis of temporal neural processing using...

Area of Science:

• Neuroscience
• Cognitive Neuroscience
• Visual Perception

Background:

• Visual perspective taking is a complex cognitive function.
• Understanding the neural underpinnings of how we process visual information from different viewpoints is crucial.

Purpose of the Study:

• To investigate the neural processing involved in visual perspective taking using high-density electroencephalography (EEG).
• To differentiate brain activation patterns between viewing objects and avatars, and between self and other perspectives.

Main Methods:

• High-density EEG recordings were used.
• Four experimental conditions were compared: Arrow, Avatar, Self, and Other.
• Analysis included activation differences, phase-locked responses, and microstate analysis.

Main Results:

• The Avatar condition showed early differences in primary visual pathways and later activation in the frontal lobe's paracentral lobule.
• Taking the 'other' perspective involved recruitment of occipital, temporal, mentalizing, and salience networks, progressing to frontal areas.
• Distinct brain processes were observed for the Avatar condition, with generator recruitment from visual to anterior brain regions.

Conclusions:

• Visual perspective taking, particularly with avatars and considering others' viewpoints, engages distinct and progressively recruited neural networks.
• Early visual processing and later recruitment of higher-order cognitive networks, including theory of mind, are essential for understanding others' perspectives.
