Left Illusions

"I make no apologies for my present position. My values have not changed, but my sense of what supports them and makes them possible has. It was what I thought was the humanity of the Marxist idea that made me what I was; it is the inhumanity of what I have seen to be the Marxist reality that has made me what I am."--David Horowitz.

Cognitive Illusions investigates a wide range of fascinating psychological effects in the way we think, judge and remember in our everyday lives. At the beginning of each chapter, leading researchers in the field introduce the background to phenomena such as illusions of control, overconfidence and hindsight bias. This is followed by an explanation of the experimental context in which these illusions can be investigated and a theoretical discussion drawing conclusions about the wider implications of these fallacy and bias effects. Written with researchers and instructors in mind, this tightly edited, reader-friendly text provides both an overview of research in the area and many lively pedagogic features such as chapter summaries, further reading lists and suggestions for classroom demonstrations.

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 ground-breaking synthesis of art and science, Diana Deutsch, one of the world's leading experts on the psychology of music, shows how illusions of music and speech--many of which she herself discovered--have fundamentally altered thinking about the brain. These astonishing illusions show that people can differ strikingly in how they hear musical patterns--differences that reflect variations in brain organization as well as influences of language on music perception. Drawing on a wide variety of fields, including psychology, music theory, linguistics, and neuroscience, Deutsch examines questions such as: When an orchestra performs a symphony, what is the "real" music? Is it in the mind of the composer, or the conductor, or different members of the audience? Deutsch also explores extremes of musical ability, and other surprising responses to music and speech. Why is perfect pitch so rare? Why do some people hallucinate music or speech? Why do we hear phantom words and phrases? Why are we subject to stuck tunes, or "earworms"? Why do we hear a spoken phrase as sung just because it is presented repeatedly? In evaluating these questions, she also shows how music and speech are intertwined, and argues that they stem from an early form of communication that had elements of both. Many of the illusions described in the book are so striking and paradoxical that you need to hear them to believe them. The book enables you to listen to the sounds that are described while reading about them.

This book is based on an extensive filmed conversation between Howard Burton and Diana Deutsch, Professor of Psychology at UC San Diego and one of the world’s leading experts on the psychology of music. This conversation provides behind the scenes insights into her discovery of a large number of auditory illusions, including the so-called Octave Illusion, which concretely illustrate how what we think we’re hearing is often quite different from the actual sounds that are hitting our eardrums. This carefully-edited book includes an introduction, Revealing Mistakes, and questions for discussion at the end of each chapter: I. Eclectic Beginnings - Music, art, philosophy, and philosophical psychology II. Tones, Pitches and Critical Values - Intriguing results in music and memory III. The Octave Illusion - How to confuse the brain with tones IV. Medical Applications - A highly suggestive result for epilepsy patients V. Eyes vs. Ears - The neurophysiological differences between vision and hearing VI. Gut Issues - The impact of discomfort VII. The Scale Illusion - Auditory scene analysis and evolutionary factors VIII. Surrounded by Illusions - From the Glissando Illusion to Tchaikovsky’s 6th IX. Perfect Pitch & Tone Languages - Why Mandarin might help your musicianship X. Towards Monotony? - The tonal implications of globalization XI. Embracing Discomfort - The benefits of being confused About Ideas Roadshow Conversations Series This book is part of an expanding series of 100+ Ideas Roadshow conversations, each one presenting a wealth of candid insights from a leading expert in a relaxed and informal setting to give non-specialists a uniquely accessible window into frontline research and scholarship that wouldn't otherwise be encountered through standard lectures and textbooks.

Visual illusions are compelling phenomena that draw attention to the brain's capacity to construct our perceptual world. The Compendium is a collection of over 100 chapters on visual illusions, written by the illusion creators or by vision scientists who have investigated mechanisms underlying the phenomena. --

Although current debates in epistemology and philosophy of mind show a renewed interest in perceptual illusions, there is no systematic work in the philosophy of perception and in the psychology of perception with respect to the concept of illusion and the relation between illusion and error. This book aims to fill that gap.

Most of us believe that we are unique and coherent individuals, but are we? The idea of a "self" has existed ever since humans began to live in groups and become sociable. Those who embrace the self as an individual in the West, or a member of the group in the East, feel fulfilled and purposeful. This experience seems incredibly real but a wealth of recent scientific evidence reveals that this notion of the independent, coherent self is an illusion - it is not what it seems. Reality as we perceive it is not something that objectively exists, but something that our brains construct from moment to moment, interpreting, summarizing, and substituting information along the way. Like a science fiction movie, we are living in a matrix that is our mind. In The Self Illusion, Dr. Bruce Hood reveals how the self emerges during childhood and how the architecture of the developing brain enables us to become social animals dependent on each other. He explains that self is the product of our relationships and interactions with others, and it exists only in our brains. The author argues, however, that though the self is an illusion, it is one that humans cannot live without. But things are changing as our technology develops and shapes society. The social bonds and relationships that used to take time and effort to form are now undergoing a revolution as we start to put our self online. Social networking activities such as blogging, Facebook, Linkedin and Twitter threaten to change the way we behave. Social networking is fast becoming socialization on steroids. The speed and ease at which we can form alliances and relationships is outstripping the same selection processes that shaped our self prior to the internet era. This book ventures into unchartered territory to explain how the idea of the self will never be the same again in the online social world.
