Understanding visual perceptual organization remains a challenge
for vision science. Perceptual Organization in Vision: Behavioral
and Neural Perspectives explores ideas emanating from behavioral,
developmental, neuropsychological, neurophysiological, and
computational approaches to the problem of perceptual organization.
The growing body of research on perceptual organization has
converged on a number of critical issues, most of which are
addressed in this volume. These include issues concerning the
nature and order of organizational processes, the stimulus factors
that engage the mechanisms of organization, the developmental stage
at which the mechanisms of organization are available, the role of
past experience and learning in organization, the neural mechanisms
underlying perceptual organization, and the relations between
perceptual organization and other cognitive processes, in
particular, object recognition and visual attention. Divided into
four parts, the book is designed not only to detail the current
state of the art in the field but also to promote an
interdisciplinary approach to the study of perceptual organization.
Part I presents an overview of the problem of perceptual
organization, different frameworks for understanding perceptual
organization, and a state-of-the-art summary of the domain. Part II
details which organizational processes are hardwired in the
perceptual system, which are acquired through experience, and how
object perception relates to other aspects of cognition. Part III
describes various attempts to understand the neural mechanisms
underlying perceptual organization using two different
approaches--neurophysiological and neuropsychological. Part IV
offers a computational approach to the problem. This book is
intended for cognitive psychologists, neuroscientists,
computational vision scientists, and developmental psychologists.
To understand mental function, we need to uncover the
representations and processes underlying our ability to comprehend
and to produce words, sentences,numbers and objects (or pictures of
them). The unique contribution of the field of cognitive
neuropsychology is the investigation of these representations and
processes in individuals who have sustained selective brain damage.
Indeed, studies of such individuals provide a window into the
mental system and allow us to explore the functional architecture
that is necessary and sufficient for cognition. This special issue
of Cognitive Neuropsychology is a collection of papers that
exemplifies this type of cognitive neuropsychology research. The
special issue is designed to honour and pay tribute to Eleanor M.
Saffran, one of the pioneers of this discipline, who adopted this
approach in her wide-ranging investigations of individuals with
cognitive impairment following brain damage. The papers included in
this collection all explore issues concerning behavioural and
neural mechanisms mediating cognition and are divided into four
separate sections. Two of these focus on language, with the
emphasis of the first on single word recognition and the second on
processes that are invoked beyond the single word level. Conceptual
and semantic processes are covered in a third section and the final
section is concerned with issues related to more peripheral
processes, which, when impaired, give rise to alexia, agnosia
and/or agraphia. This extensive collection of papers represents a
comprehensive overview of the current state of the field and the
papers elucidate the most recent findings in the domain of
cognitive neuropsychology.
