The issue of the relationship between cognition and motor processes can be - and has been - raised at different levels of analysis. At the neurophysiological level it refers to the interactions between afferent and efferent information. At the neurological and neuropsychological level it relates to the mutual dependencies between the sensory and the motor part of the brain, or, more precisely, between sensory and motor functions of various parts of the brain. In psychology, the issue under debate concerns, at a molecular level, the relationship between percep tion and movement or, at a more molar level, the relations between cognition and action. For the title of this book we deliberately decided to combine two terms that are taken from two of these levels ,in order to emphasize both the multilevel structure of the issues involved and the multidis ciplinary nature of the following contributions. Although the term "cognition" has been tremendously misused in recent years (at least in psychology), it is still the only term available to serve as a convenient collective name for all sorts of cognitive processes and functions.

Excerpt from The Accuracy of Voluntary Movement In view of all this interest, it is somewhat surprising that the subject of movement has received so little attention from one of the great departments of psychological research. We have as yet no psychophysics of the voluntary movements. By this I mean that we have no large mass of detailed study into the normal relations of voluntary movement to consciousness. We have nothing in this line that can compare with the immense amount of work done on the relation of perception to the stimulus perceived; or, to widen our view, we have nothing in the general subject of voluntary movement that can compare in completeness with the work done and still doing in all depart ments of sensation.

In recent years there has been steadily increasing interest in motor behavior and a growing awareness that a person not only has to know what to do in a particular situation, but also how to do it. The question of how actions are performed is of central concern in the area of motor control. This volume provides an advanced-level treatment of some of the main issues. Experiments concerned with basic processes of motor control typ ically examine very simple movements. At first glance these tasks appear to be far removed from real-world tasks, but it should be kept in mind that they are not studied for their own sake. One of the main reasons for using them is the well-recognized, but sometimes questioned, scientific principle that basic laws may be discovered more easily in simple situations than iIi complex situations. Another reason is that the simple tasks studied constitute building blocks of more complex tasks. For example, some complex skills can be consid ered as consisting of sequences of aimed movements, although, as no one would doubt, knowing everything about these individual movements does not mean knowing everything about, for example, typing. The first two chapters of the present volume focus on behavioral and physiological studies of programming and preparation of move ments. In the first chapter D. Rosenbaum introduces the concept of a motor program that is set up in advance of the overt movement.

Emerging and currently available technologies offer great promise for helping older adults, even those without serious disabilities, to live healthy, comfortable, and productive lives. What technologies offer the most potential benefit? What challenges must be overcome, what problems must be solved, for this promise to be fulfilled? How can federal agencies like the National Institute on Aging best use their resources to support the translation from laboratory findings to useful, marketable products and services? Technology for Adaptive Aging is the product of a workshop that brought together distinguished experts in aging research and in technology to discuss applications of technology to communication, education and learning, employment, health, living environments, and transportation for older adults. It includes all of the workshop papers and the report of the committee that organized the workshop. The committee report synthesizes and evaluates the points made in the workshop papers and recommends priorities for federal support of translational research in technology for older adults.
