Effects of spatial separation on behavioral data and model predictions. (A) Data adapted from (Eriksen and Eriksen, 1974). When spatial separation between flankers and target increased (measured in degrees of visual angle), the compatibility effect in RT decreased. (B) For the compatibility bias model, a similar pattern of effects can be obtained if we assume that the prior bias for compatibility is not a fixed quantity, but rather a function of distance (see text for details). (C) The spatial uncertainty model can also capture the effects if we assume that the receptive fields overlap diminishes with separation (see text for details).
