How do the signal detection indices react to frequency context bias for intensity scaling?

Stimulus frequency context effects were noted for stimuli with positive, ne gative and no skew, using aqueous NaCl stimuli of different concentrations as a model system and orange juice stimuli with added amounts of sucrose as a beverage system. The hypothesis that analysis by signal detection Deltam values, rather than individually rated intensity values, would result in t he absence of the context effect, was not confirmed.
