Current methods assume that stronger coupling between object motion and neural activity indicates higher attention, but this can be confounded by eye movement artifacts and stimulus properties. This study investigates how visual eccentricity\u2014the distance between a visual object and the fixation point\u2014affects neural responses when eye movement artifacts are controlled.\n                    <jats:italic>Approach.<\/jats:italic>\n                    Electroencephalography (EEG) signals were recorded across three tasks that manipulated object eccentricity and attention conditions while participants maintained gaze fixation. Correlation analysis and match-mismatch decoding were performed to quantify the neural tracking of object motion.\n                    <jats:italic>Main results.<\/jats:italic>\n                    The analysis supports three conclusions: (1) neural tracking of object motion in natural videos works under gaze fixation; (2) the strength of this tracking under gaze fixation is modulated by attention; and (3) there exists a significant eccentricity confound in the EEG responses, with poorer neural tracking of motion at larger eccentricities.\n                    <jats:italic>Significance.<\/jats:italic>\n                    These results indicate that findings from previous free-viewing studies also reflect genuine neural processing rather than mere oculomotor artifacts. However, the identified eccentricity effect highlights a major limitation for current decoding approaches that assume coupling strength reflects attention levels alone.\n                  <\/jats:p>","DOI":"10.1088\/1741-2552\/aea449","type":"journal-article","created":{"date-parts":[[2026,9,8]],"date-time":"2026-09-08T22:50:51Z","timestamp":1788907851000},"page":"056024","update-policy":"https:\/\/doi.org\/10.1088\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Eccentricity confound in EEG-based visual attention decoding from gaze-fixated neural tracking of motion in natural videos"],"prefix":"10.1088","volume":"23","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4307-8137","authenticated-orcid":true,"given":"Yuanyuan","family":"Yao","sequence":"first","affiliation":[{"name":"STADIUS Center for Dynamical Systems, Signal Processing and Data Analytics"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Celina Salamanca","family":"Gonz\u00e1lez","sequence":"additional","affiliation":[{"name":"STADIUS Center for Dynamical Systems, Signal Processing and Data Analytics"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4120-4232","authenticated-orcid":true,"given":"Simon","family":"Geirnaert","sequence":"additional","affiliation":[{"name":"STADIUS Center for Dynamical Systems, Signal Processing and Data Analytics"},{"name":"Research Group ExpORL"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6686-7262","authenticated-orcid":false,"given":"C\u00e9line R","family":"Gillebert","sequence":"additional","affiliation":[{"name":"KU Leuven, Brain and Cognition"},{"name":"Leuven Brain Institute (LBI)"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3307-9723","authenticated-orcid":false,"given":"Tinne","family":"Tuytelaars","sequence":"additional","affiliation":[{"name":"Processing Speech and Images (PSI)"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4827-8568","authenticated-orcid":true,"given":"Alexander","family":"Bertrand","sequence":"additional","affiliation":[{"name":"STADIUS Center for Dynamical Systems, Signal Processing and Data Analytics"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"266","published-online":{"date-parts":[[2026,9,18]]},"reference":[{"key":"jneaea449bib1","doi-asserted-by":"publisher","first-page":"769","DOI":"10.1016\/j.neuron.2018.01.008","type":"journal-article","article-title":"Neuromodulation of attention","volume":"97","author":"Thiele","year":"2018","journal-title":"Neuron"},{"key":"jneaea449bib2","doi-asserted-by":"publisher","first-page":"781","DOI":"10.1073\/pnas.95.3.781","type":"journal-article","article-title":"Event-related brain potentials in the study of visual selective attention","volume":"95","author":"Hillyard","year":"1998","journal-title":"Proc.
