Visual working memory involves the way we memorize, maintain, update, and remove visual information, e.g. “how do you remember someone’s face?” Some researchers simply replace the experiment stimulus with a visual stimulus, e.g. color, shape, and orientation. Other researchers, including a lot of research we did, abuse the fact that visual stimuli can be adjusted easily and continuously. Those researchers are not only interested whether the participant remembers a stimulus or not. They are also interested in how accurate the participant remembers the item. In our lab, we use both approaches and focus on the process of remembering, recalling, and recognizing visual stimuli.
