“…In a series of experiments, Stone investigated the relationship between psychiatrists' judgments and prognostic favorability, using magnitude estimates. In the first study, Stone and Skurdal (1968) sought evidence of the applicability of the power law to prognostic judgments by having 13 psychiatrist judges assess prognosis by using a 7-point category scale. When these data were plotted against magnitude estimates, they yielded the typical downward concavity similar in form to that obtained for brightness, loudness, and other sensory functions in Stevens's psychophysical research.…”

Recent developments in psychophysics termed statistical decision theory (or signal detection theory; SDT) and magnitude estimation (ME) are being applied to an increasing variety of previously recalcitrant problems in clinical psychology and medical decision making. One major value of the SDT method lies in the separation of human decision making into a discrimination accuracy measure and a criterion or bias measure. This characteristic is helpful in analyzing confusing situations such as pain assessment, where any number of impressive procedures or manipulations can and do affect the person's willingness to report pain but leave unaffected the detectability of pain-producing stimuli. ME methods as applied to personality research do not limit an individual's assessment of his or her personal reactions (e.g., degree of anxiety or intoxication) to a narrow range of categories devised by the experimenter but allow each person to construct as sensitive and unique a scale as is required. These methods also show superior agreement with psychophysiological measures of such factors. ME and SDT represent a significant advance over current chaotic and unreliable practices in terms of their greater objectivity and precision, parsimonious use of a single language for the laboratory and the clinic, and potential for the quantification of subtle covert psychological behaviors. This review describes applications of SDT and ME to the assessment and understanding of pain, anxiety, psychoactive drugs, and medical decision making.Although scientific progress has been slow technological advance quite rare in psycholin clinical psychology, it has not been for ogy: the discovery and elaboration of general lack of important problems to study.
