Increment-decrement asymmetry in dichoptic matching with haploscopically superimposed backgrounds

Chichilnisky & Wandell [(1995). Vision Research, 35, 239-254], studying dichoptic asymmetric colour matching with haploscopically superimposed backgrounds explained their data in terms of a model that assumes incremental multiplicative sensitivity control. The model given in Mausfeld & Niederée [(1993). Perception, 22, 427-462] postulates a different incremental multiplicative sensitivity control for incremental and decremental stimuli. It accounts for systematic deviations between Chichilnisky and Wandell's predictions and data as well as for a certain type of increment-decrement asymmetry not compatible with their model.
