Focus on psychometrics. Scaling stimuli with magnitude estimation

Magnitude estimation has been shown to be a useful model for scaling physical and social stimuli. This scaling method holds promise for researchers who are interested in scaling the individual's perceptions of physiological states such as breathlessness as well as social phenomena such as intrusiveness or difficulty in performing a task. The purpose of this article is to provide information about magnitude estimation as a scaling method in general and about the use of magnitude estimation to scale the individual's subjective responses to stimuli.
