Mechanisms of Averaging

We should emphasize in what way the averaging takes place. The dictates of different landmarks, or different dimensions of experience, are averaged , in a weighted fashion, to come up with a single intermediate criterion as a basis for responding. The different dictates are not ‘fighting' directly over the control of the muscular outputs. This is what can generate a single-peaked search distribution at an intermediate location, rather than two different peaks, one appropriate for each dictate. The weights dictate just which intermediate position becomes the target criterion.
