Continuing the debate over whether consciousness causes behaviour or plays no functional role in it, leading scholars discuss the question in terms of neuroscience, philosophy, law, and public policy.

It is argued that theoretical models cannot use qualia as explanatory tools, and cannot explain them either; thus, there is no way to make qualia do any useful work at all, at least in a theory. However, qualia do occur in both imagery and perception, and this article presents some ways of thinking about qualia from a functional perspective. Imagery differs from perception in its function. It is not a faded copy of perception. It is less distinct than perception because (...) it is only as distinct as it needs to be, not because it is inherently indistinct. Qualia represent functionally relevant encodings whether in perception or imagery. The present approach is functionalist and quite similar to Pani's. (shrink)

Consciousness has long been a subject of interest in philosophy and religion but only relatively recently has it become subject to scientific investigation. Now, more than ever before, we are beginning to understand this mental state. Developmental psychologists understand when we first develop a sense of self; neuropsychologists see which parts of the brain activate when we think about ourselves and which parts of the brain control that awareness. Cognitive scientists have mapped the circuitry that allows machines to have some (...) form of self awareness, and neuroscientists investigate similar circuitry in the human brain. Research that once was separate inquiries in discreet disciplines is converging. List serves and small conferences focused on consciousness are proliferating. New journals have emerged in this field. A huge number of monographs and edited treatises have recently been published on consciousness, but there is no recognized entry point to the field, no comprehensive summary. This encyclopedia is that reference. Organized alphabetically by topic, coverage encompasses a summary of major research and scientific thought regarding the nature of consciousness, the neural circuitry involved, how the brain, body, and world interact, and our understanding of subjective states. The work includes contributions covering neuroscience, psychology, philosophy, and artificial intelligence to provide a comprehensive backdrop to recent and ongoing investigations into the nature of conscious experience from a philosophical, psychological, and biological perspective.
