Flexible updating of information in Visual Working Memory (VWM) is crucial to deal with its limited capacity. Previous research has shown that the removal no longer relevant takes some time complete. Here, we sought study course such by tracking accompanying drop load through behavioral and neurophysiological measures. In a first experimental session, participants completed visuospatial retro-cue task which Cue-Target Interval (CTI) was manipulated. Performance revealed it about half second make full use retro-cue. dynamics load-related electroencephalographic (EEG) signals track information. We applied Multivariate Pattern Analysis (MVPA) EEG data from same task. However, contrary previous indicating MVPA can be used uniquely decode VWM load, results suggested classifiers were mainly sensitive selection, visual cue variations, or eye movements accompany manipulations, not so much per se. These findings advise caution when using as may confounding operations.
