Why do we need two eyes? Why are all cats grey at night and appear to move faster the day? Why is the sky blue and the setting sun red? This book explains the multifaceted nature of perception, and discusses the mysteries of vision. It provides readers with experiments to help them discover optical illusions and the features of their own perception. Illusions of Seeing begins with a discussion on the essence of light and its perception to the human eye. It presents a comprehensive overview of the basic laws of human perception as well as the fundamentals of good gestalt. Subsequent chapters discuss geometric-optical illusions; the perception of form, brightness, and translucency and their interaction with each other; ambiguous perception, color vision, spatial vision. The book ends with a discussion of the perception of motion and its interaction with color, form, and spatial depth with a full chapter devoted to illusions in our everyday life. Consider this your travel guide in the marvelous world of sight, to experience a completely individual way to understand and improve your own perception. Illusions of Seeing will be of interest to psychologists, physicists, biologists, and undergraduate and graduate students within the field of cognitive psychology.

In this richly illustrated study, the first book-length exploration of illusionistic art in the early United States, Wendy Bellion investigates Americans' experiences with material forms of visual deception and argues that encounters with illusory art shaped their understanding of knowledge, representation, and subjectivity between 1790 and 1825. Focusing on the work of the well-known Peale family and their Philadelphia Museum, as well as other Philadelphians, Bellion explores the range of illusions encountered in public spaces, from trompe l'oeil paintings and drawings at art exhibitions to ephemeral displays of phantasmagoria, "Invisible Ladies," and other spectacles of deception. Bellion reconstructs the elite and vernacular sites where such art and objects appeared and argues that early national exhibitions doubled as spaces of citizen formation. Within a post-Revolutionary culture troubled by the social and political consequences of deception, keen perception signified able citizenship. Setting illusions into dialogue with Enlightenment cultures of science, print, politics, and the senses, Citizen Spectator demonstrates that pictorial and optical illusions functioned to cultivate but also to confound discernment. Bellion reveals the equivocal nature of illusion during the early republic, mapping its changing forms and functions, and uncovers surprising links between early American art, culture, and citizenship.
