Notes:
Using a Rank-Rating method, d’values were obtained for stimuli from a model system using 15-point, 9-point, 7-point and 5-point category scales. For an apple/grape juice system, d’values were compared for 9-point and 7-point scales. There was general agreement on d’values among the scales, except where stimuli had their scores ‘bunched’into one category: this tended to occur for the strongest and weakest stimuli for Rank-Rating and for the scales with fewer points. Bunching altered distribution variances and distorted the calculated d’values. Further study gave d’values for the discrimination of confusable stimuli, using paired-comparison and rating data, thus providing numerical measures of their relative sensitivity.
