Eccentricity Confound Eeg Visual Attention Decoding

EEG Visual Attention Decoding with Eccentricity Control

Overview

Methodology for decoding visual attention from EEG signals during naturalistic video viewing, with explicit control for eccentricity confounds from eye movement artifacts and stimulus properties.

Problem

Current methods assume stronger coupling between object motion and neural activity indicates higher attention, but this is confounded by:

• Eye movement artifacts related to visual eccentricity
• Stimulus properties that vary with position in visual field

Core Methodology

1. Eccentricity-aware preprocessing: Control for position-dependent artifacts
2. Motion-neural coupling analysis: Measure neural tracking of object motion
3. Attention decoding: Isolate genuine attention signals from confounds
