Book Description
Optical illusions constitute errors that accompany the brain's data reduction processes involved in pattern discrimination. The acquisition of an understanding of the cause of these visual aberrations will provide knowledge about the pattern recognition algorithms used by the eye and central nervous system which can aid efforts to model the brain's functions. The disparity between the 'apparent' line and the actual line that occurs in the case of peripheral vision is sufficient to produce the perceptual errors that occur in the Poggendorff, Hering and Muller-Lyer illusions. The magnitude of the Poggendorff illusion as a function of the line angle is derived and experimentally tested. The equations are further developed and used to derive Pollack's experimental results on figural after effects. The use of these concepts allows a degree of modeling of the central nervous system data reduction processes that may be of value in the development of pattern recognition for computer use. (Author).

Book Description
This book is based on a two-day symposium at the Paris Institute of Advanced Study titled "space-time geometries and movement in the brain and the arts". It includes over 20 chapters written by the leading scientists and artists who presented their related research studies at the symposium and includes six sections; the first three focus on space-time geometries in perception, action and memory while the last three focus on specific artistic domains: drawing and painting, dance, music, digital arts and robotics. The book is accompanied by a dedicated webpage including related images and videos. There is an ever-growing interest in the topics covered by this book. Space and time are of fundamental importance for our understanding of human perception, action, memory and cognition, and are entities which are equally important in physics, biology, neuroscience and psychology. Highly prominent scientists and mathematicians have expressed their belief that our bodies and minds shape the ways we perceive space and time and the physical laws we formulate. Understanding how the brain perceives motion and generates -bodily movements is of great significance. There is also growing interest in studying how space, time and movement subserve artistic creations in different artistic modalities (e.g., fine arts, digital and performing arts and music). This interest is inspired by the idea that artists make intuitive use of the principles and simplifying strategies used by the brain in movement generation and perception. Building upon new understanding of the spatio-temporal geometries subserving movement generation and perception by the brain we can start exploring how artists make use of such neuro --geometrical and neuro-dynamic representations in order to express artistic concepts and emotionally affect the human observers and listeners. Scientists have also started formulating new ideas of how aesthetic judgements emerge from the principles and brain mechanisms subserving motor control and motion perception. Covering novel and multidisciplinary topics, this advanced book will be of interest to neuroscientists, behavioral scientists, artificial intelligence and robotics experts, students and artists.

Book Description
Heinz Werner (1890-1964) was one of the three key developmental psychologists of the 20th century – along with Jean Piaget and Lev Vygotsky. This book is a new exploration of Werner’s ideas and their social contexts – in Vienna in his student years, in Hamburg up to 1933, followed by the years of transit as an immigrant to America at times of economic depression, finally culminating in his establishment of the prominent "Clark tradition" in American psychology in the 1950s. The book offers an in-depth analysis of Werner’s ideas as they were originally formulated in Vienna and Hamburg, and how they were changed by North American influences. Werner’s pivotal role between European and American intellectual traditions is illuminated through the use of rich memories of his former students, unique documents from Werner’s personal library at Clark, and analyses of links with other European traditions in philosophy and biological sciences. The European period (prior to 1933) in Werner’s academic life is found to be definitive for Werner’s contributions to science. The ideas developed in his early career continued in the form of a productive empirical research program in the 1950s at Clark. An analysis of the social-intellectual climate of the development of psychology in America in the 1950s is a special feature of this book that will further enhance an understanding of Werner’s unique contribution This book will be of interest to developmental psychologists, sociologists and historians of science, philosophers, practitioners working in special education and neuropsychology, and for general readers interested in the history of ideas and life courses of scientists.

Book Description
Originally published in 1981, this third volume deals with the empirical data base and the theories concerning visual perception – the set of mental responses to photic stimulation of the eyes. As the book develops, the plan was to present a general taxonomy of visual processes and phenomena. It was hoped that such a general perspective would help to bring some order to the extensive, but largely unorganized, research literature dealing with our immediate perceptual responses to visual stimuli at the time. The specific goal of this work was to provide a classification system that integrates and systematizes the data base of perceptual psychology into a comprehensive intellectual scheme by means of an eclectic, multi-level metatheory invoking several different kinds of explanation.
