“…Ample evidence from the visual perception literature has documented the importance of semantic and spatial object-to-object relations to online unitization or to ''perceptual grouping'' processes (e.g., Auckland, Cave, & Donnelly, 2007;Davenport, 2007;Green & Hummel, 2006;Gronau & Shachar, 2014;Oppermann, Hassler, Jescheniak, & Gruber, 2012;Roberts & Humphreys, 2011). More relevant to the present research, several studies have demonstrated the significance of such unitization processes for visual memory encoding and retrieval processes (e.g., Hollingworth, 2006;Mandler & Parker, 1976;Mandler & Ritchey, 1977).…”
