title: Constancy of individual exponents for inspired lung volume: a comment on Harver (1987).
abstract: In this paper we made two brief commentaries on Harver's (1987) experiment. The first comment is an observation on the growing area of respiratory psychophysics for which we prefer the name Behavioral Physiology. In the second comment it is suggested that the stable individual differences in the exponent of the psychophysical power law reported by Harver may be an artifact of the psychophysical method employed: category production.
