PSYCHOPHYSICS: TOP-DOWN AND BOTTOM-UP ENABLE â€˜MEASURING THE IMPOSSIBLEâ€™
â€˜Measuring the Impossibleâ€™ (MtI) refers to recent innovative research activities related to the measurement of quantities and qualities that are dependent on human perception and/or interpretation. Its interdisciplinary nature interconnects various monodisciplinary research areas; physics, physiology, mental part of psychology, and (overt) behavioral sciences. These four also depict the different aspects of inner and outer psychophysics. Outer psychophysics regards physiological and mental processing as a combined â€˜black boxâ€™ within which no measurement is performed. A key question within MtI and in inner psychophysics is how to explicate the mental or psychophysiological processes taking place within the â€˜black boxâ€™ and this is cardinal to developing new theories and methods of measurement. To accomplish this, we argue that the two traditional Bottom-Up and Top-Down approaches have to be integrated into a dual-directional Research Strategy Loop involving complex communication systems beyond the straight-forward psychophysical relationship.
