Stimulus comparison by human observers is a more complex process than the subtraction carried out by a simple comparator. This is shown by the patterns of time- and space-order "errors." Specifically, experiments show that the two compared stimuli exert differential influence on the comparative response. This invalidates models based on additive bias or semantic congruity. The sensation-weighting (SW) model can account for many of the results. One important consequence is that the discriminability of two stimuli depends on which of them is varied.
