Abstract

This paper provides the evidence base to construct a professional standard for discriminative scaling of taints and optima. The measurement of suboptimal sensed characteristics of a product has logical and empirical requirements that specify a single overall rating of each sample in a tetrad. Those four pairs of response/stimulus data determine the discrimination distance of each sample from the comparison in memory used by the assessor, together with the position of that standard on the straight line specified by the two stimulus levels in the tetrad. The rating's reference anchor can be the match to a familiar version of the product or the personally most preferred level. Each sample can be assessed again for sensory and/or conceptual attributes, using vocabulary learned in life or by sensory training. Those data give the ideal or matching value of that verbal category and the individual's tolerance of deviations from that value.
