Considerable evidence exists that visual sensory information is analyzed simultaneously along two or more independent pathways. In the past two decades, researchers have extensively used the concept of parallel visual channels as a framework to direct their explorations of human vision. More recently, basic and clinical scientists have found such a dichotomy applicable to the way we organize our knowledge of visual development, higher order perception, and visual disorders, to name just a few. This volume attempts to provide a forum for gathering these different perspectives.

Is there a right way' to study coordination? What experimental paradigms are appropriate? Are there laws and principles that the biological system uses to coordinate movement? Do all biological systems - human and otherwise - share these same principles? Is coordination inherited or acquired? Is it a central nervous system, muscular, or mechanical problem? Indeed, what is coordination and how can it be quantified? This volume attempts to help to answer some of these questions by bringing together a collection of conceptual approaches to and empirical investigations of the coordination of...

Since the end of the sixties, Piagetian general theory with its inherent power of unification has gradually given way to a multitude of more specific models which is in evidence today. In this volume the authors concentrate on three perspectives namely cognitive, perceptuo-motor and neuropsychological development and attempt to coordinate these traditionally separated views. Good illustrations of these theoretical connections can be found in different chapters although the persistent isolation of these three domains still remains. However the authors believe efforts in developmental...

Real advances are not made in blind alleys (or culs-de-sac). In Social Psychology, as in every branch of science, the paths which appear to offer progress do not always result in theoretical elegance. Certain basic problems persistently defy final solution. This volume surveys the foundations and methods of Social Psychology with the aim of identifying ways out of the research maze. It examines the history and traditions of the field, looks at methodology and conceptual schemes, and discusses the actual research methods used.

Dementia diseases are the most common cause of severe mental deterioration in the world today, and expected changes in the population structure will inevitably result in a gradually increasing occurrence of dementia. One of the primary symptoms of dementia diseases is severe memory dysfunction. Knowledge about the ways in which dementia diseases affect memory increases our knowledge about the relationship between brain structures and memory functions, is imperative for early clinical diagnosis, and forms a basis for sound behavioral and pharmacological intervention. While the memory...

Left-handedness has been shown to be a possible marker for various psychological and physical abnormalities. This book presents evidence by a number of researchers who evaluate whether there are indeed differences between left- and right-handers which extend into the broader psychological and physiological realms. Several chapters show that left-handedness is found in unexpectedly high proportions in populations that suffer from various immune deficiency diseases, in alcoholics, dyslexics, mental retardates, psychopaths and other clinical groups. The book indicates why left-handedness should...

This volume is an historically based critical evaluation of Freud's personality theory. In it the observations Freud made are described and the theoretical ideas he put forward for explaining them are set out. The adequacy of Freud's explanations are judged against the logical and scientific standards of Freud's own time. The historical perspective will give the reader a sound basis on which to make a judgement about psycho-analysis as a method of investigation and a theory of personality as well as a sense of what Freud was about from Freud's own standpoint. Freud's endeavour is sited in the...

This book contains a number of chapters on the control and execution of skilled movements, as well as more general chapters on theoretical issues in skilled performance. The contributors have summarised their most recent research, and general themes and issues are presented in discussion chapters at the end of each section, thus providing a good general summary of the kind of research and theoretical frameworks developing in this area. The first section is concerned with the theoretical issues of programming and co-ordination. Issues raised in the second section are basic to much of the...

This volume is the outcome of an international symposium held in Berlin, FRG, which brought together researchers in the field of infant development. The contributors are from Europe and North America, and have as their primary professional interest either pediatrics, biology or psychology. These fields, in spite of common involvement and large overlap, still have to overcome communication problems and differences in scientific approaches. The emphasis of this book is on the efforts of the participants towards reaching a mutual understanding. In spite of disciplinary diversity, the papers in...
