The encoding of information involves integrating multiple pieces of information, which constitutes an essential ability for higher cognitive functions such as working memory. Common tasks used to measure working memory capacity include binding tasks, which assess the ability to build and maintain associations between mental representations, and updating tasks, which involve flexibly changing these associations between different pieces of information. However, the underlying neurocognitive processes behind these tasks remain unclear. In this talk, we present findings from a study that investigated the specific and general neurophysiological mechanisms involved. To do this, we designed a set of tasks in order to distinguish and examine the nature of binding and two types of updating processes: substitution and transformation. Participants (N= 150, female = 89, Mage = 34.77, SD = 12.78) completed a binding and two updating tasks while an EEG was recorded. Mass univariate cluster-based permutation analyses of event-related potentials revealed a temporally and spatially widespread cluster when comparing binding and updating demands. These differences may reflect neurophysiological correlates of early attentional processes and the costs associated with updating. Additionally, the comparison between the two types of updating demands—substitution and transformation—revealed a more temporally concentrated cluster within the typical P3 time window. As a result, our findings highlight significant differences in the neurophysiological processes involved in binding and updating, while suggesting greater similarities between the various updating demands.
