Representation of the visual and spatial properties of our
environment is a pivotal requirement of everyday cognition. We can
mentally represent the visual form of objects. We can extract
information from several of the senses as to the location of
objects in relation to ourselves and to other objects nearby. For
some of those objects we can reach out and manipulate them. We can
also imagine ourselves manipulating objects in advance of doing so,
or even when it would be impossible to do so physically. The
problem posed to science is how these cognitive operations are
accomplished, and proffered accounts lie in two essentially
parallel research endeavours, working memory and imagery. Working
memory is thought to pervade everyday cognition, to provide on-line
processing and temporary storage, and to update, moment to moment,
our representation of the current state of our environment and our
interactions with that environment. There is now a strong case for
the claims of working memory in the area of phonological and
articulatory functions, all of which appear to contribute to
everyday activities such as counting, arithmetic, vocabulary
acquisition, and some aspects of reading and language
comprehension. The claims for visual and spatial working memory
functions are less convincing. Most notable has been the assumption
that visual and spatial working memory are intimately involved in
the generation, retention and manipulations of visual images. There
has until recently been little hard evidence to justify that
assumption, and the research on visual and spatial working memory
has focused on a relatively restricted range of imagery tasks and
phenomena. In a more or less independent development, the
literature on visual imagery has now amassed a voluminous corpus of
data and theory about a wide range of imagery phenomena. Despite
this, few books on imagery refer to the concept of working memory
in any detail, or specify the nature of the working memory system
that might be involved in mental imagery. This essay follows a line
of reconciliation and positive critiquing in exploring the possible
overlap between mental imagery and working memory. Theoretical
development in the book draws on data from both cognitive
psychology and cognitive neuropsychology. The aim is to stimulate
debate, to address directly a number of assumptions that hitherto
have been implicit, and to assess the contribution of the concept
of working memory to our understanding of these intriguing core
aspects of human cognition.
