Originally published in 1982, Living in a World Transformed is now back in print. DolezalÆs book features his experiences wearing up-down reversing prisms attached to a football helmet while living in a Greek coastal village. Along with other daily activities, he hiked and water skied. His first study, the ôPrism Study,ö was an explanation of adaptation phenomena. The author sought to describe the change in how the visual system interacts with the motor systems when the available optical information incorrectly specifies the location of places, objects, people, and events. The second study, the ôTube Study,ö seeks to show how resourceful people can be under another unique condition of survival: living in a confined visual world by severely restricting the normal field of view. The results and analysis argue that such studies produce perceptual confusions and errors in action that have frequently been confounded with, and attributed to, the optical transformation rather than to the restriction of the field of view.Dolezal, Hubert is the author of 'Living in a World Transformed: Perceptual and Performatory Adaptation to Visual Distortion (Academic Press Series in Cognition and Perception)' with ISBN 9780122199509 and ISBN 0122199502.
