"Students of vision, and more generally, anyone interested in studying the growth of ideas of a brilliant researcher will find this to be a remarkable collection of papers....Gunnar Johansson's distinguished career as an exceptionally skilled and creative experimentalist and an original and remarkably insightful theoretician is clearly displayed in this volume. This collection of his papers, and the accompanying commentaries, constitute one of the more important additions to the perceptual literature in recent years by chronicling some of the most significant experimental work of psychology's past half century."—The Psychological Record"This book takes a long stride in penetrating the importance of OST (optic sphere theory) in contemporary perception."—Contemporary Pshychology
