This book is a multi- and interdisciplinary volume in which scientists from the psychological, physical, biological, and social sciences reach a common understanding of measurement theory and methods. "Birgitta Berglund and Giovanni Battista Rossi, two distinguished and active scientists in the field, have brought together in this volume a set of valuable papers by experts. It is a most welcome contribution to an important area of measurement science." -Ludwik Finkelstein, Ph.D.,OBE FREng, City University, United Kingdom "This collection of 16 chapters on human measurement topics follows the 20th Century tradition of Handbooks except for being uniquely international in scope. It appears to stem from the annual meeting of the International Society for Psychophysics. Of course, brain imaging is a substantial presence." -R. Duncan Luce, Ph.D., University of California, Irvine, USA
