Although it was treated respectfully by early researchers such as Wilhelm Wundt, William James, and Edward Titchener, the concept of consciousness virtually disappeared from academic psychology until the 1980s, when it made a triumphant return to the behavioural sciences and reappeared as a legitimate subject of empirical study. There is, however, no succinct handbook or dictionary covering the most important experimental phenomena and research paradigms that have become the psychophysical basis for the modern empirical study of consciousness. This volume provides the first systematic listing and description of the typical experimental phenomena and effects where consciousness appears as a variable of interest. The authors describe the names and labels of these phenomena, the principal authors behind the respective research, the basic experimental designs needed to produce research, and provide a list of useful references that will help readers to expand and deepen their own knowledge of the consciousness.
