Visual working memory capacity does not modulate the feature-based information filtering in visual working memory.

<h4>Background</h4>The limited capacity of visual working memory (VWM) requires us to select the task relevant information and filter out the irrelevant information efficiently. Previous studies showed that the individual differences in VWM capacity dramatically influenced the way we fil...
