Dual Processing of Aberrant Data Perception: Evidence From EEG Oscillations.

Area of Science:

• Neuroscience
• Cognitive Science
• Social Psychology

Background:

• Perception of aberrant data (PAD) is crucial for social interaction.
• The dual processing mechanisms underlying PAD, involving automatic processes (APs) and controlled processes (CPs), are not well understood.

Purpose of the Study:

• To investigate the neural oscillatory activity mediating APs and CPs in PAD using electroencephalogram (EEG).
• To elucidate the representational patterns of neural oscillations during dual processing in PAD tasks.

Main Methods:

• EEG time-frequency analysis was employed to examine neural activity during a PAD task.
• The study analyzed β and α oscillations, cross-frequency phase coherence, and intersite phase coherence in frontal-parietal regions.

Main Results:

• β oscillations showed event-related desynchronization in AP mode and synchronization in CP mode within frontal-parietal regions.
• A novel β-kα index effectively separated AP and CP modes (p < 0.001).
• Efficient communication via cross-frequency coherence and information integration via intersite coherence underpinned AP mode.

Conclusions:

• This research provides a framework for understanding the neural basis of dual processing in PAD.
• Findings offer insights into potential applications for neurodegenerative diseases and clinical interventions related to social cognition.
