The influence of object and background color manipulations on the electrophysiological indices of recognition memory

Target-context unitization effect on the familiarity-related FN400: A face recognition exclusion task

“…In other words, when it is not possible to process the relevant contextual feature and facial identity simultaneously, the familiarity signal is not prone to contextual influences. The present results are thus in line with previous work showing that the FN400 is modulated in source-memory tasks or associative-recognition tasks involving the retrieval of intrinsic features (e.g., Ecker et al, 2007a,b;Mecklinger, 2006;Nyhus and Curran, 2009), whereas it is not sensitive to the conscious retrieval of extrinsic information (Ecker et al, 2007b;Mollison and Curran, 2012).…”

“…On the other hand, the parietal old-new effect, which very likely relies on the activity of a fronto-temporo-parietal network (Aggleton and Brown, 2006) has been linked to the retrieval of specific information associated with a target, such as landscape-object associations (Tsivilis et al, 2001). It is also reduced if a feature is changed between study and test (Curran and Cleary, 2003;Ecker et al, 2007b;Groh-Bordin et al, 2006). Finally, a late frontal old-new effect, topographically dissociable from the late parietal old-new effect, is typically associated with generic monitoring and post-retrieval processes (Johnson and Rugg, 2006;Hayama et al, 2008;Johnson et al, 1998).…”

Visual and spatial working memory: From boxes to networks

“…Though this difference has not yet been considered in research on WM, I expect that it is relevant for these tasks, too, especially because location and object information should be bound by different processes (inter-versus intra-item, respectively). For example, in long-term memory tasks we could demonstrate that binding of object and color information has other electrophysiological signatures if color is an object feature than if it is a background feature (Ecker et al, 2007). Similar results are to be expected in WM tasks.…”

ERP evidence for hemispheric asymmetries in exemplar-specific explicit memory access

“…Task-relevant changes to ͷ perceptual intra-item features or exemplar-changes, as well as changes to the context of study items have reliably reduced the recollection-related LPC old/new effect. In contrast, the FN400 old/new effect as a correlate of familiarity is not affected by contextual changes (Ecker et al, 2007a(Ecker et al, , 2007b). Yet, presenting perceptually changed versions or different exemplars of study items at test has reduced the FN400 old/new effect, at least when stimulus encoding was perceptually focused (Ecker et al, 2007a;2007b;Groh-Bordin et al, 2005;2006;Schloerscheidt & Rugg, 2004;Grove & Wilding, 2009).…”

When perceptual information was not prioritized, however, equivalent FN400 old/new effects have emerged for studied and modified items (Curran, 2000;Curran & Cleary, 2003;Curran & Dien, 2003;Küper et al, 2012).…”
