| Outline of Final Research Achievements |
The capacity of visual working memory is limited to representing three simple objects that no longer exist in the external environment. Interestingly, we previously found that this severe capacity limit also applies to representing objects that remained visible (Tsubomi, Fukuda, Watanabe, & Vogel, 2013). Here, we further found that only a few object worth of visual information can be maintained robustly against the interference at a given moment regardless of whether the objects are present or not. Meanwhile, there is another type of large-capacity visual representations that are vulnerable to interference and decay over time after the objects disappear. In addition, we also found that the capacity-limited representations are completely removed within 1 second after its use without necessitating the encoding of new visual input when they are deemed no-longer necessary.
