Abstract: Binding problem is a central issue of cognitive sciences and neurosciences and is at the core of the dispute on consciousness. Much of mental life involves the manipulation of binding of features from different objects. The mechanisms that maintain these bindings within working memory are essential to efficient functioning. Feature binding in visual working memory turns to be a heated topic recently. Most related studies focus on whether visual working memory stores bound features, the relation between the storage of separate features and bound features, and the role of attention in the storage of bound features. However, there are not clear answers to above questions till now.

Key words: feature binding, working memory, attention, vision
