Context Binding in Visual Working Memory Is Reflected in Bilateral Event-Related Potentials, But Not in Contralateral Delay Activity

↵1 Note that although one of the studies summarized here failed to find evidence of stimulus information in delay-period signal in IPS (i.e., Emrich et al., 2013), several other studies have found evidence for stimulus information in delay-period signal in IPS (e.g., Ester et al., 2015; Samaha et al., 2016; Bettencourt and Xu, 2016; Gosseries et al., 2018; Rademaker et al., 2019; Cai et al., 2020). The idea that IPS may contribute to context-binding operations, the focus of this report, does not exclude the involvement of this region in other functions, including stimulus representation.

↵2 Note that there are other types of “nonrepresentational factor,” not manipulated here, to which the CDA has been shown to be sensitive. For example, multiple-object tracking tasks yield a much larger CDA than WM tasks, and WM for random polygons yields higher CDAs than WM for simple features (for more details, see Luria et al., 2016).
