One of the most important discussions in psychophysics is related to the measurement and quantifying of the variations in sensory reactions. In a sensory system which physical stimuli are entries and sensations are the outcomes, the measurement functions will be achievable while both the stimuli and sensory reactions are measurable. In color science, the mentioned functions could be applied to investigate the color difference formulae, the color emotion of observers, the way of representing an index to evaluate the objects’ color and so on. The application of these functions in textile area is related to investigate the fabric structural properties based on sensory parameters, i.e., fabric handle attribute, softness and fineness. It is noticeable that the final result is based on quantifying of perceived sensory attributes. Clearly, it is difficult to perceive and quantify these psychophysical phenomena. On the other hand, in order to avoid serious errors, unsuitable computation and incorrect results, it is necessary for a researcher to know the measurement methods and the corresponded scales to analyze the achieved data. In this way, the paper tries to review the measurement methods as well as the manner of allocation of scales to sensory attributes.
