“…The perceptual functioning may be unnecessarily influenced by, for example, habituation and diurnal variation (see, e.g., Engen, 1973). It is probable that the time-saving method of successive approximations (Svensson & Szczygiel, 1974) and the well-controlled design of the present experiment have been of importance for the demonstrated findings. Magnitude matching with successive approximations is therefore regarded by the authors as a valuable complement to modern psychophysical scaling methods in perceptual research.…”

Magnitude matchings of odor intensity were obtained for three chemical compounds (hydrogen sulfide, pyridine, and dimethyl disulfide) in four experiments. An equal-sensation function in the form of a power function described the data well. This equation can be written neglecting the multiplicative constant, 1>i = 1>kbik, where i and k represent two different odorants. The exponent bik, where the first index stands for matching continuum and the second index for reference continuum, was fairly well predicted according to the formulae,

“…In order to obtain a precise control of the stimulation during the matchings, a new method of successive approximations with automatic equipment was developed (Svensson & Szczygiel, 1974). The reference stimulus is presented in one of the hoods and the matching stimulus in the other.…”
