Instead, contextual information is interpreted. We investigated the levels of processing at which this interpretation occurs. Combining three experimental paradigms, we explored whether masked and more implicitly coded objects are already size-rescaled. We induced object size rescaling using a modified variant of the Ebbinghaus illusion. In this variant, six dots altered the size of a central stimulus and served as inducers generating Object-Substitution Masking (OSM). Participants reported the average size of multiple circles using the size-averaging paradigm, allowing us to test the contribution of masked and non-masked central target circles. Our Ebbinghaus illusion variant altered perceived stimulus size and showed robust masking via OSM. Furthermore, size-averaging was sensitive enough to detect perceived size changes in the magnitude of the ones induced by the Ebbinghaus illusion. Finally, combining all three paradigms, we observed that masked and non-masked stimuli contributed to size averaging in a size-rescaled manner. In a control experiment testing the general effects of Ebbinghaus inducers, we observed a contrast-like effect on size averaging. Large inducers decreased the perceived average size, while small inducers increased it. In summary, our experiments indicate that context integration, induced by the Ebbinghaus illusion, alters size representations at an early stage. These modified size representations are independent of whether a target is recognisable. Moreover, perceived average size appears to be coded relative to surrounding perceptual groups.Keywords: Context integration; Ebbinghaus illusion; Object-substitution masking (OSM); Rescaled size perception in masked objects; Size averaging; Size illusion. 001035384 536__ $$0G:(DE-HGF)POF4-5251$$a5251 - Multilevel Brain Organization and Variability (POF4-525)$$cPOF4-525$$fPOF IV$$x0 001035384 536__ $$0G:(GEPRIS)491111487$$aDFG project G:(GEPRIS)491111487 - Open-Access-Publikationskosten / 2025 - 2027 / Forschungszentrum Jülich (OAPKFZJ) (491111487)$$c491111487$$x1 001035384 588__ $$aDataset connected to CrossRef, Journals: juser.fz-juelich.de 001035384 7001_ $$0P:(DE-Juel1)190278$$aYildiz, Gizem Y.$$b1 001035384 7001_ $$0P:(DE-Juel1)131720$$aFink, Gereon R.$$b2$$ufzj 001035384 7001_ $$0P:(DE-Juel1)131747$$aWeidner, Ralph$$b3$$ufzj 001035384 773__ $$0PERI:(DE-600)1499940-7$$a10.1016/j.cognition.2024.106041$$gVol. 256, p. 106041 -$$p106041 -$$tCognition$$v256$$x0010-0277$$y2025 001035384 8564_ $$uhttps://juser.fz-juelich.de/record/1035384/files/1-s2.0-S0010027724003275-main.pdf$$yOpenAccess 001035384 8564_ $$uhttps://juser.fz-juelich.de/record/1035384/files/PDF.pdf$$yOpenAccess 001035384 8767_ $$d2025-01-10$$eHybrid-OA$$jDEAL 001035384 909CO $$ooai:juser.fz-juelich.de:1035384$$pdnbdelivery$$popenCost$$pVDB$$pdriver$$pOpenAPC_DEAL$$popen_access$$popenaire 001035384 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)190281$$aForschungszentrum Jülich$$b0$$kFZJ 001035384 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)131720$$aForschungszentrum Jülich$$b2$$kFZJ 001035384 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)131747$$aForschungszentrum Jülich$$b3$$kFZJ 001035384 9131_ $$0G:(DE-HGF)POF4-525$$1G:(DE-HGF)POF4-520$$2G:(DE-HGF)POF4-500$$3G:(DE-HGF)POF4$$4G:(DE-HGF)POF$$9G:(DE-HGF)POF4-5251$$aDE-HGF$$bKey Technologies$$lNatural, Artificial and Cognitive Information Processing$$vDecoding Brain Organization and Dysfunction$$x0 001035384 9141_ $$y2025 001035384 915pc $$0PC:(DE-HGF)0000$$2APC$$aAPC keys set 001035384 915pc $$0PC:(DE-HGF)0125$$2APC$$aDEAL: Elsevier 09/01/2023 001035384 915__ $$0StatID:(DE-HGF)0200$$2StatID$$aDBCoverage$$bSCOPUS$$d2024-12-20 001035384 915__ $$0StatID:(DE-HGF)0160$$2StatID$$aDBCoverage$$bEssential Science Indicators$$d2024-12-20 001035384 915__ $$0StatID:(DE-HGF)1050$$2StatID$$aDBCoverage$$bBIOSIS Previews$$d2024-12-20 001035384 915__ $$0StatID:(DE-HGF)1190$$2StatID$$aDBCoverage$$bBiological Abstracts$$d2024-12-20 001035384 915__ $$0StatID:(DE-HGF)0600$$2StatID$$aDBCoverage$$bEbsco Academic Search$$d2024-12-20 001035384 915__ $$0StatID:(DE-HGF)0100$$2StatID$$aJCR$$bCOGNITION : 2022$$d2024-12-20 001035384 915__ $$0StatID:(DE-HGF)1180$$2StatID$$aDBCoverage$$bCurrent Contents - Social and Behavioral Sciences$$d2024-12-20 001035384 915__ $$0StatID:(DE-HGF)0510$$2StatID$$aOpenAccess 001035384 915__ $$0StatID:(DE-HGF)9900$$2StatID$$aIF < 5$$d2024-12-20 001035384 915__ $$0StatID:(DE-HGF)0030$$2StatID$$aPeer Review$$bASC$$d2024-12-20 001035384 915__ $$0StatID:(DE-HGF)0130$$2StatID$$aDBCoverage$$bSocial Sciences Citation Index$$d2024-12-20 001035384 915__ $$0StatID:(DE-HGF)0300$$2StatID$$aDBCoverage$$bMedline$$d2024-12-20 001035384 915__ $$0LIC:(DE-HGF)CCBY4$$2HGFVOC$$aCreative Commons Attribution CC BY 4.0 001035384 915__ $$0StatID:(DE-HGF)0420$$2StatID$$aNationallizenz$$d2024-12-20$$wger 001035384 915__ $$0StatID:(DE-HGF)0199$$2StatID$$aDBCoverage$$bClarivate Analytics Master Journal List$$d2024-12-20 001035384 920__ $$lyes 001035384 9201_ $$0I:(DE-Juel1)INM-3-20090406$$kINM-3$$lKognitive Neurowissenschaften$$x0 001035384 980__ $$ajournal 001035384 980__ $$aVDB 001035384 980__ $$aUNRESTRICTED 001035384 980__ $$aI:(DE-Juel1)INM-3-20090406 001035384 980__ $$aAPC 001035384 9801_ $$aAPC 001035384 9801_ $$aFullTexts
