The episodic buffer component of working memory is assumed to play a central role in the binding of features into objects, a process that was initially assumed to depend upon executive resources. This suggested a need to assume a feature-based attentional filter followed by an object based storage process. Those results are interpreted within a modified version of the multicomponent working memory model. The programme of research that we describe was motivated by an attempt to further develop our earlier multicomponent approach to working memory and in particular to explore the concept of an episodic buffer. This chapter focuses on the interface between the central executive and the episodic buffer, combining dual task methodology with the methods already developed to study binding in visual working memory. The studies that have described so far are purely behavioral, although they do have implications for the neurobiological basis of binding in both visual working memory, and broadly within the episodic buffer.
