Individual Differences in Conscious Experience is intended for readers with philosophical, psychological, or clinical interests in subjective experience. It addresses some difficult but important issues in the study of consciousness, subconsciousness, and self-consciousness. The book's fourteen chapters are written by renowned, pioneering researchers who, collectively, have published more than fifty books and more than one thousand journal articles. The editors' introductory chapter frames the book's subtext: that mind-brain theories embodying the constraints of individual differences in subjective experience should be given greater credence than nomothetic theories ignoring those constraints. The next five chapters describe research and theory pertaining to individual differences in conscious sensations — specifically, individual differences in pain perception, phantom limbs, gustatory sensations, and mental imagery. Then, two succeeding chapters focus on individual differences in subconsciousness. The final six chapters address individual differences in altered states of self-consciousness — dreams, hypnotic phenomena, and various clinical syndromes. (Series B)

Philosophical 'thought experiments' invoking inverted spectra, zombies, et cetera suggest that conscious sensations have no function, and psychological studies finding no correlation between vivid visual imaging and visual problem solving suggest that conscious images have no function. Furthermore, both philosophical and psychological theories suggest that self-consciousness has no function. Countering such suggestions, the post-Darwinian double-aspect theory which Professor Robert Kunzendorf's introduces in the first chapter of his monograph On the Evolution of Conscious Sensation, Conscious Imagination, and Consciousness of Self points to evolutionary functions of certain sensations, youngling vivid images, and self-consciousness. Kunzendorf's second chapter presents evidence that the most primitive sensation-pain, the subjective aspect of free nerve endings or nociceptors-has a survival-promoting function. But as the pressure nociceptor mutates into a touch receptor, the heat nociceptor into temperature receptor, and the chemical nociceptor into a taste receptor, the painful qualia of these nociceptors evolve respectively into touch sensation, temperature sensation, or taste sensation-painless sensations that add no survival benefit to their receptor's physical aspect. Building on evidence that retinal receptors embodying visual qualia evolved from primitive eyespots responsive to injurious 'heat at a distance' or painful light, the third chapter presents evidence that visually imagined sensations are the subjective qualities of retinal receptors that are corticofugally innervated in warm-blooded animals-for the developmental purpose of testing cortically hypothesized sensory-motor rules that have greater survival value than cold-blooded stimulus-response associations. The fourth and final chapter focuses on self-conscious reality-testing and on visuo-spatial self-conceptualization, and presents evidence that such manifestations of self-awareness evolve only in those warm-blooded animals whose rule-developing youth lasts two years or longer-that is, those mammals and birds whose survival during the imaginal testing of rules is subjected to prolonged risk if self-consciousness that one is imaging sensations (rather than perceiving sensations) is absent.

A leading neuroscientist explores with authority, with imagination, and with unparalleled mastery how the brain constructs the mind and how the brain makes that mind conscious. Antonio Damasio has spent the past thirty years researching and and revealing how the brain works. Here, in his most ambitious and stunning work yet, he rejects the long-standing idea that consciousness is somehow separate from the body, and presents compelling new scientific evidence that posits an evolutionary perspective. His view entails a radical change in the way the history of the conscious mind is viewed and told, suggesting that the brain’s development of a human self is a challenge to nature’s indifference. This development helps to open the way for the appearance of culture, perhaps one of our most defining characteristics as thinking and self-aware beings.

Scientists elucidate the astounding collective sensory capacity of Earth and its evolution through time.

Writing in a rigorous, thought-provoking style, the author takes us on a far-reaching tour through the philosophical ramifications of consciousness, offering provocative insights into the relationship between mind and brain.

The Arthur M. Sackler Colloquia of the National Academy of Sciences address scientific topics of broad and current interest, cutting across the boundaries of traditional disciplines. Each year, four or five such colloquia are scheduled, typically two days in length and international in scope. Colloquia are organized by a member of the Academy, often with the assistance of an organizing committee, and feature presentations by leading scientists in the field and discussions with a hundred or more researchers with an interest in the topic. Colloquia presentations are recorded and posted on the National Academy of Sciences Sackler colloquia website and published on CD-ROM. These Colloquia are made possible by a generous gift from Mrs. Jill Sackler, in memory of her husband, Arthur M. Sackler.
